Batasminimal tegangan ELKO harus diatas 18 Volt, usahakan yang 50v saja. ===== UPDATE Untuk rekan FauzyMuliaMakmur Aku pernah reparasi simbada multi media yang dipakai untuk komputer Madrasah, suaranya JOS banget. sy tes pake PSU mantan CPU komputer 12v, bunyi crriieeettt.. sama tda 2050 puuaaanaas.. spek PSU nya 12v+ 16A, 12v- nya 0,5A.. Memangtidak bisa dapat tegangan pas 24v, jadi bisa dapat tegangan kurang lebih 24v. Silahkan ambil tegangan ct 15v dari trafo, maka akan jadi 15vac x 1,414=21vdc. Atau ambil tegangan ct 18v dari trafo, maka akan jadi 18vac x 1,414= 25vdc. Nah tinggal pilih, tegangan mana yang cocok untuk power supplynya. Pakai tegangan 21v atau 25v. Bisamas. Dari out psu 12v, masuk inverter ct 24v. Jadi nanti outputnya jadi +24v ct -24v. Untuk mendapatkan tegangan +24v non ct, maka tinggal konek ke CT dan +24v saja. Untuk -24v gak digunakan. Jadi tinggal Anda belikan kit inverter 12v to ct 24v. Untuk merubah tegangan 12v menjadi ct 24v. Untuk koneksi 24v non ct, tinggal gunakan pin ct dan +24v. PowerSupply ATX 24 Pin ATX jenis ini adalah power Supply ATX yang menggunakan 4 pin tambahan yang digabungkan dengan power 20 pin, dan 4 pin lagi terpisah yang berupa tambahan 12 volt.

And if yours has recently stopped beating, or you’re upgrading your computer with more powerful components, you need a new one. Choosing a new power supply can be tricky, since you’ll need to determine the required power draw, or wattage, of the rest of your components. You’ll also have to select a model that fits in your PC, and one that has the correct cables rails to fit your components. Then you’ll need to install it, and since the power supply is directly connected to multiple components, it’s a rather involved procedure. Let’s break it down. Picking a New Power Supply Choosing the right power supply is essential for making sure your PC runs well. Without an adequate supply of regulated electricity, your desktop might suffer from performance issues, or possibly not boot at all. How Much Power Do I Need? The amount of power a power supply delivers is measured in watts. They generally provide from around two hundred for the smallest and most efficient machines to over a thousand one kilowatt for the biggest, beefiest gaming and media desktops. Determining how much power you need is a matter of adding up the power draw from all of your components. The biggest two power draws on a PC are typically CPU and graphics card. That’s assuming you use a graphics card, of course—not all PCs have a separate card, and sometimes even a discrete card is low-power enough to draw its electricity directly from the motherboard. But if your PC is built for gaming or even light media editing duties, you’ll need to account for it. Other components also draw power, including hard drives, optical drives, and cooling systems like fans or radiators. These are typically require much lower power, and can usually get away with rough estimates. If you want to estimate your power requirements, look at the specifications of each component in particular. For example, our test machine at How-To Geek uses an Intel Core i7-7700K processor. On Intel’s website, we see that the processor draws an average of 91 watts under high load. Here are the power requirements for the rest of our test build’s components Processor 91 watts Graphics card Radeon RX 460 114 watts at peak Motherboard 40-80 watts RAM under 5 watts per DIMM – estimate 20 watts for our build SSD under 10 watts 120mm fan for CPU cooler under 10 watts Based on these general figures, we can estimate that the How-To Geek desktop won’t use more than 350 watts under its full load. And since the graphics card specifications recommend at least a 400 watt power supply, that’s where we’ll start. A margin of error is a handy thing to have, not to mention the fact that having a little extra power gives you room to add more components in the future—like extra storage drives or cooling fans. If you’re not entirely sure about your PC’s power supply needs, check out this handy online calculator. Just plug in your components and it gives you a recommended wattage. Add a little bit for a safety margin, and you have wattage you need your PSU to deliver. What Form Factor Should I Choose? After you’ve determined how much power you need, you’ll need to find a power supply that physically fits in your computer. That’s what “form factor” means there are a few standardized sizes for power supplies, and odds are that one of them will fit the case you’re already using. The most common size for power supplies is “ATX”—the same standard name for a consumer-grade “tower” computer. These fit into almost all full-sized desktop computers, and you’ll find them ranging in power from around 300 watts all the way up to 850 watts. Some ATX-standard power supplies are longer than normal, stretching to eight or ten inches long, but keeping their width and height standardized. These are the monsters that can power high-end CPUs, multiple GPUs, arrays of storage drives, and a wind tunnel’s worth of cooling fans, stretching from 900 watts all the way up to 1200 watts and beyond. Sometimes these extra-large ATX power supplies will have trouble fitting into a standard case, and require oversized “gaming” or workstation cases. Unless you specifically bought or built your computer to have a ton of power, you probably don’t have to worry about it. If you do have a monster PC, look up the case’s specifications it will let you know the maximum dimensions of the power supply bay. On the opposite end of the spectrum, some cases are too small for even a normal-sized ATX power supply. These include “small form factor” cases and those that are meant to hold smaller standardized motherboards, like Micro-ATX and Mini-ITX. These power supplied generally top out at around 400 watts, though some more expensive and more powerful units are made. At this size things can get confusing, since some enthusiast Mini-ITX cases can also fit a full-sized ATX power supply for beefy gamer configurations. SFX and TFX power supplies are for small, compact cases. If you go even smaller, things tend to get non-standardized, and you’ll want to look for a replacement for your specific model. If you’re upgrading because you don’t have enough power in your current power supply and your case won’t accept anything bigger, you’ll likely need to upgrade your case as well, and move all of your other components into it. At this point, a complete PC replacement might be more practical. What Cables Do I Need? The cables that run from your power supply to the various components in your PC generally standardized, but there are three crucial types you want to check for compatibility with your specific machine Main motherboard cable This cable runs directly from your power supply to your motherboard, and plugs into the board using 20 or 24 pin plug. Most high-end power supplies have 20 pin plug, plus an additional 4 pin plug so that you can plug it into either type of motherboard. It’s worth paying attention to how many pins your motherboard uses and making sure you buy a power supply that can handle it. CPU motherboard cable This cable also runs to the motherboard, but is used to power your CPU. These come in 4, 6, and 8 pin varieties. Some high-end motherboards offer combinations like an 8-pin and additional 4-pin connection to spread out the voltage, but these are rare. GPU power cables These cables run from your power supply directly to a graphics card. If you don’t use a graphics card, or if the card you use doesn’t require separate power, then you don’t need to worry about these. Graphics cards that do require separate power use either a 6 or 8 pin plug. Some of the bigger cards even require two cables. Most power supplies powerful enough to run gaming rigs offer a pair of cables for your graphics card even if you only need one of them, and offer a 6 pin plug with an additional 2 pin plug so they can accomodate whatever card you use. It’s something to watch out for, though. You’ll also need cables for other components hard drives, optical drives, case fans, and so on. Modern storage and optical drives use standardized SATA power connections, and every modern power supply includes them. Case fans typically use 3 or 4 pin plugs, and again, modern power supplies usually come with at least one of these. Older drives or fans may use a 4-pin Molex connector, with larger pins and a trapezoidal plug. Many power supplies offer a rail or adapters for these, but if the model you’ve chosen doesn’t, Molex adapters are cheap and easy to find. What About Efficiency? Modern power supplies include an efficiency rating, usually indicated by the “80 Plus” voluntary certification system. This indicates that the power supply consumes no more than 20% over its output wattage; if you buy a 400 watt power supply, at full load it won’t consume more than 500 watts from your home’s electrical system. Compliance with the 80 Plus system is indicated by a sticker on the power supply, and usually advertised as a feature on the box or online listing. There are different grades of the 80 Plus sticker standard, bronze, silver, gold, platinum, and titanium. Each higher level indicates a higher point of efficiency, and generally a higher price. Almost all power supplies sold at retail reach the minimum 80 Plus requirement. Your power supply’s efficiency rating won’t affect its output—if you buy a 400 watt supply, it will deliver 400 watts to your computer, no matter how much it draws from the power outlet. But those wishing to save some money on their power bills in the long term may want to shop for a higher-rated supply. Modular Power Supplies Are Awesome Modular power supplies allow the power rails from the PSU to be unplugged both at the component side and on the power supply side. A full modular system. By comparison, a non-modular design has a big bundle of power cables permanently affixed to the steel box of the power supply itself. A non-modular power supply, with permanently-affixed cables. The advantage of a modular supply is that you don’t have to have cables in your case that you don’t need. This makes running the power cables easier, keeps things looking tidier, and helping preserve good air flow in the case. The only real downside of modular supplies is that tend to be a bit more expensive, and they’re usually only offered on higher-end power supplies. You’ll also find semi-modular designs, with permanent rails for common components like the motherboard and CPU but modular rails for the rest. They can be a handy compromise. Installing Your New Power Supply So you’ve picked out your power supply and you’re ready to install it. You’ll need a standard Philips-head screwdriver and a clean, well-lit place to work. If your home or office is particularly susceptible to static electricity, you might also want an anti-static bracelet. Oh, and before you go any further DO NOT OPEN THE METAL CASING OF THE POWER SUPPLY ITSELF. There are high-power capacitors inside that can injure or kill you if they discharge. For the same reason, don’t stick any tools or wires inside the holes for the cooling fan or exhaust, either. Removing the Old Power Supply Power down your PC, remove all the power and data cables, and then move it to your work area. You’ll want to remove any access panels from the case on some PCs, you have to remove the whole case as one piece. On a standard ATX case, these are on the right and left sides, held in place with screws on the back of the computer. Remove these screws two or three on a side, then pull back the access panels and set them aside. If you use a small form factor or other non-standard case, consult the manual. Remove as much of the exterior panels as you can to give yourself maximum access to the interior you’ll need to unplug power cables from multiple components. Now, identify all of the components plugged into your power supply. On a standard PC build, this will be Motherboard long 20 or 24 pin plug. CPU on the motherboard 4 or 8 pin plug, near the top of the motherboard. You may need to remove the CPU cooler to see this if it’s an oversized cooler. Storage drives Hard drives and solid-state drives, usually plugged in with a standard SATA cable. Multiple drives may be connected to one cable. Optical drives Also use a standard SATA cable. Older models may use a Molex adapter. Graphics cards larger, more powerful discrete cards draw power directly from the power supply, even though they’re plugged into the motherboard. 6 pin and 8 pin rails are common, with some high-end cards needing multiple rails. Case fans and radiators When not plugged into the motherboard or case itself, these fans can draw power from accessory rails using small 4 pin connections or older Molex connections. Check from both sides of your PC and multiple angles excess lengths of power and data cables are often stored behind the metal motherboard mounting tray. When you’ve identified which components are plugged into your power supply, unplug them one by one. Some may be held in place with plastic tabs, but you shouldn’t need to use anything except your fingers to unplug them. If you have to remove anything to get to these plugs, especially data cables, remember their original positions and restore them as you have access. Taking pictures as you go is a great idea. If your power supply is modular, you also can remove the power rails from the back of the power supply housing. Carefully pull them free of the PC case itself and set them aside. If your power supply isn’t modular, simply pull all the power rails to the most accessible open space and make sure they’re free of entanglements with anything else in the case. Now turn your attention to the back of the PC. The power supply is held in place with three to five screws that are accessible from the outside of the PC case. Remove them and set them aside. Some case designs differ; if you see more screws in non-standard locations on the power supply, remove them too. With all the cables unplugged and the retention screws removed, you can now pull the power supply free of the case. Depending on where the power supply is placed top or bottom of the case and what other components are nearby, pulling it out of the case might be easy or might be challenging. If it’s near the top of the case and it’s crowded by an oversized CPU cooler, for example, you might end up having to remove that cooler so you can get the power supply out. Installing the New Power Supply Now, we’re going to reverse the process. Place the new power supply in position in your PC. If it’s modular, don’t plug anything into it. If it isn’t modular, simply trail the power cables outside of the PC for easy access. You’ll want to position the exhaust fan on the top or bottom of the power supply so that it’s facing away from the motherboard and the other internal components. So if the power supply is mounted at the top of the case, point the exhaust fan up. If it’s bottom-mounted, point it down. If the exhaust fan blows out the back of the case, it doesn’t matter. Secure the power supply to the rear of the PC case with the retention screws, screwing from the outside of the case into the metal housing of the power supply. Use the screws from the previous power supply if you’re replacing it, otherwise the screws should have come with either your PC case or the power supply itself. When the power supply is fixed in place, it’s time to plug in all those cables. If your power supply is modular, plug the cables into their sockets on the back of the supply itself. Now plug the opposite end of the rails into their corresponding components. These components are fairly standardized motherboard, motherboard-CPU, storage drives and disc drives, GPU if applicable, and case fans or radiators if they’re not already plugged in. You should be able to plug everything in without any further tools. If something isn’t plugging in all the way, check the orientation of the plug; all of the multi-pin cables should only be able to fit one way. As you’re plugging in components, be wary of where you run the power cables. The inside of your PC doesn’t have to look like a showroom, but you should make sure that power and data cables don’t trail near cooling fans they can drag and tangle. Even if they’re only touching slightly, they’ll make an annoying noise once your PC is running and potentially strip the protective casing. Also, keeping cables as tidy as you can not only looks better, it helps promote good airflow inside your case and makes components easier for you to get to in the future. Once you’re sure everything’s plugged in, you might want to move your PC back to its normal position with your mouse, keyboard, and monitor before closing up. Being careful not to touch any of the interior components while it’s running, plug everything in and power it up, just to make sure it’s booting correctly. If not, then go back and check your connections again to make sure you haven’t missed a power plug or accidentally removed a data cable. Oh, and check the switch on the back of the power supply to make sure it’s in the “ON” position. If everything looks good, then unplug the external cables, close up the access panels, and screw them into place to get your PC ready for normal operation. Then place it back in its usual spot, and enjoy your new power supply.

Dipasaran tersedia berbagi macam power supply variabel mulai dari versi analog hingga digital namun tentunya dengan harga yang lumayan cukup mengurus isi kantong heheh 😁.Pada artikel sebelumnya saya telah membuat beberapa rangkaian yang boleh dibilang bisa sebagai power supply variabel analog karena memang memiliki kemampuan yang dapat mengatur tegangan keluaran secara variabel dan telah saya gunakan sejak lama untuk menemani kegiatan eksperimen proyek-proyek elektronika ringan sebelumnya dengan arus yang cukup sedang yaitu maksimal 3A dengan pengaturan tegangan melalui potensiometer maksimal 15V. Baca juga Membuat Power Supply Variable PSUKIT 0 - 30V Karena dirumah saya mempunyai beberapa koleksi atx psu atau power supply komputer dan sudah lama tidak digunakan maka saya akan mencoba memodifikasinya menjadi power supply variabel mengingat sudah banyak artikel diluaran sana yang sudah memodifikasi power supply komputer ini menjadi dapat diatur keluarannya tidak ada salahnya saya pun mencobanya. Dari beberapa power supply komputer yang saya milik ada dua buah yang memakai ic pwm tl494 atau ka7500. Kenapa harus yang memakai ic tl494? Ya alasan utamanya adalah karena sangat mudah untuk dilakukan modifikasi sebab ic tl494 memilih dua buah error amplifier didalamnya yang akan digunakan sebagai pengatur tegangan dan arus keluarannya. Skema ATX-300P4-PFCModifikasi yang dilakukan hanya pada kedua pin error amplifier tersebut yaitu pin 1 dan pin 2 serta pin 15 dan pin 16. Pin 1 dan pin 2 digunakan sebagai pengaturan tegangan dimana pin 1 digunakan sebagai limit dan pin 2 digunakan sebagai set tegangan sementara pin 15 dan pin 16 digunakan sebagai pengaturan batas arus dimana pin 15 digunakan sebagai set arus dan pin 16 digunakan sebagai limit arus. Satu lagi agar psu atx tidak protek saat tegangan keluaran lebih dari 12 V maka pin 4 Dead Time harus dimatikan atau diputus dari rangkaian proteknya, jadi pin 4 harus 0V. Dengan mematikan pin 4 maka keluaran dari psu atx ini mampu diatur sampai 25 V dengan demikian elko bagian sekunder harus diganti karena memiliki rating tegang maksimal hanya 16V, diganti dengan elko yang mempunyai rating tegang maksimal 50V. Kemudian rangkaian protek dan komponen lainnya pada bagian sekunder harus dilepas agar tidak pusing dalam melakukan modifikasi. Dibawah ini saya tampilkan skema mana saja yang perlu dimodifikasi dan komponen mana saja yang bisa dibuang.

Changing your computer’s power supply is a simple enough process that anyone can do, once you know how. This guide will teach you how to replace/change the power supply unit in your computer, step by step. We’ll also look at the main reasons why you would need to change or upgrade your computer’s power supply, and things to look out for when choosing a replacement unit so that you can get one that’s going to last. These steps apply to tower and desktop computers. The entire process can be done within around 5-20 minutes, depending on how familiar you are with the task. Tools required Screwdriver to remove power supply unit and open computer case usually Phillips head Optional Anti-static wrist strap if not using a strap, just discharge yourself by touching any exposed metal part of your computer case before you begin the job. Overview Once you’ve identified that you need to replace the power supply unit in your tower or desktop computer, follow the steps below. The replacement is simple enough, first you’ll need to remove the old power supply, and then install the new one in its place. Disconnecting and connecting the power supply is straightforward – you just need to make sure that you plug/unplug it in to all the right connection points inside your computer if you’re not sure about this, refer to the checklist and pictures later in this article. Remember, the power supply’s main function is to provide power to all of the different hardware components in your PC, so you just need to make sure that it is plugged into each one correctly. A typical power supply consists of the main box-shaped unit, as well as the attached internal wiring- you’ll need to plug the relevant connectors into the various hardware components inside your computer. The good news is that if you are replacing an existing power supply, you can just follow the same cabling connections that you just unplugged from the old power supply as a guide. This makes it easy to know what plugs in to where, as you’re simply replicating what was already there. Stage 1 Removing the Old Power Supply Unit Before you begin anything, make sure that your computer is powered off and unplugged from the wall socket. Removing the power supply from your computer is fairly simple, and you can follow the steps below. If you’re unsure, it can help to take a photo of the power supply arrangement before your unplug anything – this way you can make sure that you re-connect everything you’re supposed to later on. The bulk of the task in replacing your computer’s power supply is plugging in the power connectors from the PSU to all the hardware components inside your computer. This is the largest one that plugs into your motherboard. How To Remove An Existing Power Supply Power off the computer and unplug the power cable from the wall socket and power supply unit. If your PSU has one, flick its power switch to the off position. Open up your computer case – usually the inside of the case is accessed by unscrewing the fastening screws on the back edge of the case, and sliding the side panel off. It’s usually easiest to work with the computer laying flat on its side, with the components facing up at you. Note down the existing internal connections from the power supply to the components in your computer it can help to take a photo, or count the number of connections that are plugged in. You’ll need to reconnect these to the new supply later. Unplug any hardware connectors that are attached to the power supply wiring. Pull each cable clear out of the case as you unplug it – this will help prevent cables snagging on things when removing the unit later and also acts as a visual check so you can check that everything is unplugged. Checklist for disconnection a Motherboard b CPU c Any Storage Drives and/0r Optical Disc Drives d Graphics card if applicable e Fans if applicable The power supply is held into the computer case by mounting screws. Locate and unscrew these. Remove the old power supply unit and cabling. Stage 2 Changing to the New Power Supply Unit Installing the replacement power supply unit is basically the reverse of the steps you did to remove the old PSU. If you haven’t changed any of the hardware in your computer, simply plug the cables from the new PSU back in to each component, replicating how it was before. If you have changed some hardware components like a new graphics card, for example, you’ll just need to make sure that you follow the manufacturer’s instructions for supplying it with power via the appropriate header connector. How To Install A New Power Supply Mount the new power supply unit into the computer case by using the case mounting screws. Reconnect the internal wiring from the output of the power supply unit to the hardware components inside your computer case. Be sure to refer to the notes/photos that you took in the removal stage to make sure that all the components are reconnected. Checklist for reconnection a Motherboard b CPU power connector c Hard drives, Solid state drives, Optical drives d Any power connections needed by your graphics card – if required not all graphics cards models require power from the PSU e Fans if applicable f Refer to your notes/photos of what was previously connected, and do a final check on all connectors to make sure they’re secure Close up the computer case. Plug in the input cable to the power supply. Connects the wall socket to the power supply. If your new PSU has a power switch, don’t forget to flick it to the on position. Power up the computer and test. Reasons To Change a Power Supply Unit There are only really two main reasons why you would need to replace the power supply unit in your computer, and if neither of these concerns you then the good news is that you can probably leave it alone. Reason 1 The PSU is dead won’t power on or faulty Reason 2 The PSU is not fit for purpose What do we mean by not fit for purpose’? Basically, this means that the power supply won’t reliably do what its intended to do – power your computer components safely and reliably. PSUs that are not fit for purpose generally fall into two categories The rated power output capacity of the PSU is too low Usually, this can happen if you are upgrading components in your computer that require more power. The rated power output of a PSU is measured in Watts, and must be high enough to supply all the components within your computer. A classic example of when the power output of your PSU may suddenly become too low is if you are upgrading other components in your computer. For example, installing a new graphics card that requires more power consumption can in many cases trigger the need to replace the existing power supply to a unit with a higher output capacity. The PSU is a cheap brand or of low quality The power supply might be cheap and you don’t trust it. Unfortunately this can be the case with many pre-built computers, as cutting the budget spending on the PSU is very common. We recommend doing a little bit of research online on your particular brand/model of power supply to make sure it doesn’t have a reputation for blowing up or failing. How Do I Know What Size Power Supply I Should Have? Power supply size’ can mean two things, but usually refers to the output capacity of the unit measured in Watts. Output Capacity The output capacity of your computer’s power supply needs to be high enough to supply enough power to all of the components inside your computer case at the same time. Prebuilt Computers If you have a prebuilt computer, the designers would have calculated the maximum power requirements at any one time, and sized the PSU according to that – so you shouldn’t need to worry about the size of the PSU in your computer in this case. One thing you may have to worry about with prebuilt computers though, is the quality of the power supply. If it is a cheap/no-name brand, it may cause issues. DIY Computer Builds If you are building your own computer, then you need to work out the maximum power draw on your own in order to size your PSU. You can use calculators like this one to help you figure it out. Usually, the largest power-sucking component is your graphics card if you have a dedicated one. Many graphics card manufacturers have a minimum total system power’ recommendation in their graphics card specifications that can be used as a guideline to the total power supply size you’ll need if you want to build a computer with this graphics card. The manufacturer’s specifications for the Geforce GTX 1060 show that the minimum system power requirement is 400W. This means you’ll need to have at least a 400W power supply in your computer if you want to run this graphics card. Source GeForce Website Form Factor However, be aware that Size’ can also refer to the physical size dimensions of the power supply unit this can also be referred to as form factor’, which is the shape and general physical layout of a component. Not all power supply units are the same physical size, so you’ll definitely want to be aware of this before trying to swap out one unit for another – as the worst thing that can happen is to find out that the new one won’t physically fit where you want it to! Why You Should Care About What Power Supply Unit Is In Your Computer Remember that the power supply unit is responsible for supplying power to every hardware component that makes up your computer system. When it comes to power, there’s such a thing as quality too – when we talk about power quality, it means that the power being supplied is clean, constant, and within the expected operating limits. If you have a low-quality power supply, it may not supply a good quality power to the hardware components in your computer – which can cause performance issues, or at the extreme end of the scale, even damage or reduce the lifespan of your hardware. Unfortunately, many manufacturers of prebuilt computers tend to spend a lot of their budget on fitting in high spec’d items like a processor and graphics card – but then skimping on the power supply. The end result can be disastrous, just google something like power supply blew up’ to get an idea of what can happen… Caution Output Ratings Can Sometimes Be Misleading Cheaper brands can even tend to exaggerate their PSU’s output capacity rating example We’ve seen units to be a 300W power supply, but if you take a closer look, the rating is a 300W peak rating and the continuous rating may be less than this. If you’re planning on installing a new graphics card and still using your existing power supply unit, make sure to check the output rating first. Be especially careful to check for any trick ratings on no-name brand PSUs if you are pushing the upper limits of your existing rated power supply unit. It’s usually safer to oversize your PSU, just to be sure!. It’s really important to make sure your power supply is decent in order to protect your other hardware components and ensure they have a long life. 80 Plus Certification One certification to look out for is the 80+ certification, which means that the power supply is at least efficient and has less than 20% losses. While this is not specifically related to overall quality of a PSU, the fact that the PSU you’re considering buying has a certification of some sort is an indication that the manufacturers have considered quality at some level. What Brands To Use One of our favorite recommended brands of power supplies is EVGA because we like their warranty on some of their products its up to 10 years!, but there are plenty of reputable brands out there. Top-of-the-line/premium brands are ones like Seasonic and Superflower. If you’re looking for something a little more budget-friendly, then brands like SilverStone, Cooler Master, Corsair, Thermaltake and EVGA are all decent as well. Again – don’t forget to look for the 80 Plus ratings! Deending on the brand and Watt rating, prices can vary. Summary Changing the power supply unit in your computer is a relatively easy task that anyone can do – just follow the steps outlined in this post. You only need to replace your computer’s PSU if it is faulty or damaged, or if it’s not fit for purpose either a cheap/unreputable brand, or no longer large enough for your needs. If you’re upgrading other components within your computer – particularly graphics cards – this can trigger the need to replace your existing power supply unit for a larger one. Output capacity of a PSU is measured in Watts and should be calculated based on your other computer hardware – you can use online calculators or manufacturer’s specifications to help you find the required PSU size that you need. Make sure to stay safe when switching out hardware components in your PC, by turning off mains power before you access any internal parts of your computer.
