Power supply for pc
A power supply is a critical component of any gaming PC. Without a power supply, your computer would essentially be a giant paperweight. Power supplies turn the alternating current (AC) from your wall outlet into the direct current (DC) that your components need to operate.
When building a custom gaming PC, it’s important to get the right size power supply for your build. The easiest way to do this is to use one of our pre-made Gaming PC Builds and then select from our list of recommended power supplies.
Computer power supply voltage and amperage
The power supply’s job is to take AC current and convert it to DC current, which is what your computer needs. The power supply’s voltage and amperage work together to create the wattage as a whole. Your power supply will provide the wattage your computer needs based on the components you have installed.
Power Supply for Gaming PCs
While power supplies don’t vary too wildly in cost, they can vary significantly in watts and amps.
For example, a PSU with 500 watts might not be enough for the GPU and CPU of a gaming PC that uses an SLI or Crossfire setup.
When building your own gaming PC, you should always check the recommended wattage for your specific components.
**Recommended Power Supply Sizes for Gaming PCs**
While there are two main types of power supplies-modular and non-modular-the wattage plays a big part when considering which one to buy. A modular power supply is one where all cables are separate, so you only have to connect the cables you will actually be using at that time.
Non-modular power supplies have all cables attached and must be installed before connecting them to the motherboard. For this reason, we recommend buying a modular PSU if possible as it makes installation easier and ensures that you’re only using what’s necessary at any given time.
**How to Size Your Power Supply**
The best way to size your power supply is to take into account your system’s peak voltage requirements (measured in volts). This is typically displayed on your system specs page on manufacturer sites like ASUS ROG Forums or Gigabyte OC Forum for their respective systems.
If those websites aren’t available, then search the internet for “X system specs” (in X replace the product name of your system) and it should show up when
Computer power supply voltages
A computer power supply is an important component in any gaming PC. It converts the alternating current (AC) from a wall outlet into direct current (DC) that your components need to be able to operate. Without a power supply, your computer would essentially be a giant paperweight.
What size power supply do I need for my gaming PC?
The size of a power supply is measured in watts. The higher the watts, the more power the supply can provide. To determine what size power supply you need for your gaming PC, first figure out the rated wattage of your computer parts (CPU, GPU and motherboard). Then add up those ratings to get your total wattage.
For example: if you have a GPU that requires 300W, a CPU that requires 250W and a motherboard with 150W requirements then your total wattage requirement would be 675W. In this case, it would be best to go with a 750-watt power supply or larger to ensure there’s enough headroom for your components to grow without causing an overload on your PSU.
Power Supply for Gaming PCs
Power Supplies can vary a lot, but you need to pay close attention to the wattage. You want to make sure you have enough wattage for your components. For example, if you are putting together a gaming PC with a high-end graphics card, you will need more power than if that same build didn’t have such a heavy graphics card.
Generally speaking, a 500W power supply should be enough for most builds (depending on what kind of components are inside). That being said, there are many different kinds of power supplies out there and it’s important to get one that matches your needs.
There is no one size fits all when it comes to power supplies. One thing to keep in mind is that they can’t be returned once they’re opened so make sure you buy an adequate sized one!
**BONUS TIP:** Although it falls outside the scope of this guide, we recommend using a modular power supply whenever possible and purchasing from reputable brands like Corsair or Crucial.
How to size a power supply for Pc gaming
Since there are many different factors to consider when choosing a power supply, it can be a bit of a guessing game. We’ve put together some guidelines to help you make the best decision possible.
It’s important that you select a power supply that can handle the wattage required by your components. If you’re using a high-powered video card or multiple video cards, your power supply needs to be larger than if you were using just a single card.
For example, an 850 Watt power supply is large enough for an overclocked Quad Core CPU and one high-end video card such as the NVIDIA GeForce GTX 480. However, this same power supply may not be powerful enough in the event you have more than one high-end video card in your gaming PC build.
If you’re building a gaming PC from scratch, it’s recommended that you purchase at least a 600 Watt power supply for your build. This will cover most of what gamers need in terms of wattage and should provide adequate headroom for future upgrades.
If you plan on running multiple GPUs, we recommend going with at least 850 Watts or higher (depending on how many GPUs). In addition to considering the amount of watts needed by the component(s), it’s also important to think about what types of connectors will be used by the component(s).
For example, if you’re planning on running two hard drives and two optical drives off of one SATA power connector on one cable then this will cut into your available
What Type of Computer Power Supply Should You Buy?
500W Power Supply
If you have a low-end system, then a 500W power supply will be more than enough to power your system.
650W Power Supply
If you’re building a mid-range gaming PC, then a 650W power supply should be enough.
750W Power Supply
A 750W PSU is perfect for building a high-end gaming PC with multiple graphics cards.
850W Power Supply
For extreme high-end gaming PCs with multiple graphics cards and overclocking the CPU or GPU, an 850W power supply is recommended. These types of systems are typically reserved for hardcore gamers, who demand the most out of their systems.
What Size Power Supply Do I Need for My Gaming PC?
The amount of power you need depends on the components in your gaming PC. Generally, a 350-500 W power supply is adequate for most people. However, if you have lots of high-end hardware, like multiple graphics cards, or a custom water cooling system, you may need more power.
Two good places to start are 500 W and 850 W PSUs as they will offer enough power for the majority of people’s gaming systems. Additionally, PSUs with more wattage do not necessarily produce better performance. In fact, some can even be dangerous to use because they can provide more voltage than necessary.
Which Wattage Should You Buy?
The main factor when choosing the wattage of your power supply is how powerful your gaming PC is. If you have a high-end gaming PC, you’ll want a higher wattage PSU to power all the components in your system. For example, if you’re buying a 1000 W PSU, it’s perfect for a high-end system with many GPUs or overclocked CPUs with multiple cores.
If you’re building an average mainstream computer, you’ll get by with a 550 W PSU (the most popular size) and should probably stay under 650 W.
If you’re not sure what size power supply unit to buy for your gaming PC, here’s our quick guide:
Which Power Supply Type Should You Buy?
If you’re building a high end gaming PC, you’ll want to get a high-end power supply unit for your build. A 1000 W PSU is the optimal choice for gamers running a multi-GPU setup. If your budget is limited and you don’t plan on using multiple graphics cards, a 750 W PSU would be more than enough.
Many people find 500W to be adequate for building a low-end gaming PC. But if you’re looking to upgrade in the future, it’s best to go with a higher wattage. For example, if you plan to buy a video card that requires 400W or more of power, it’s better to start off with a 600W PSU so that you’re not limited down the road.
What are the benefits of using a high-end power supply?
High-end power supply units come with greater wattage ratings than mainstream power supply units. For example, a 1000 W high-end PSU can provide more power to your gaming PC than a 500 W mainstream PSU. Higher wattage means that it’s capable of supplying more power to your system.
This means your computer will have an easier time dealing with heavy demands, like when playing intensive games. If you plan to use CPU overclocking or GPU overclocking, the higher wattage of a high-end PSU makes it better suited for those tasks.
The increased wattage rating can also help keep your computer cool by providing ample power that can overcome heat generated by intense graphics and processing.
Best power supply for gaming pc
A power supply is a vital component of any gaming PC. Without one, your PC would essentially be a giant paperweight.
There are two different types of power supplies: modular and non-modular. The main difference between these is that modular power supplies have the power cables (usually 24-pin ATX cable, 8-pin EPS cable, 4+4 pin CPU cable, and 6+2 pin PCI-E cable) all built in to the unit. Non-modular power supplies require you to plug in cables before use.
The size of the PSU is also an important factor to consider when purchasing one. One hundred watts will be enough for most builds, but it’s important to consider how many components you plan on having in your build as well as where you’re going to place it inside your case.
If you want to stack your components close together, then a larger PSU will be necessary. Otherwise, you may find yourself running out of space or potentially damaging something by placing too much pressure on it.
When selecting a power supply for your build, there are three things that should be considered: wattage (size), efficiency rating (category), and the number and type of connectors included with the unit.
A higher wattage means higher performance while lower efficiency ratings mean lower operating temperatures which can help keep noise levels down inside your system. Higher quality connectors mean less chance they’ll break and more stability while providing more current capacity at lower voltage drops which in turn means

To calculate how much power you need for your gaming PC, you’ll want to use a PSU calculator. You can use this calculator from our friends at Tom’s Hardware to get an idea of the size of power supply that will work best for your build.
How to choose the best PC power supply
Choosing the right power supply for your build is essential to ensuring that your gaming PC will be able to successfully run all of its components. If you purchase a power supply that is too small, it won’t be able to provide enough power for your rig. Similarly, if your power supply is too large for your system setup, it will just waste energy.
Fortunately, there are a variety of ways you can choose the best PC power supply for your specific build. The first is by calculating how much wattage (W) you need based on the specs of the components in your computer.
You also have the option to use an online calculator like this one which simplifies the process. The option you choose depends on how confident you feel with your math skills and what type of calculations you’re comfortable with.
After doing some calculations and choosing the right option, simply compare power supplies until you find one that has the correct wattage and meets all other requirements such as connectors or PCI-E support. The last way to choose a power supply is by following our guide below:
Is 1000 watts good for a gaming PC?
A 1000 watt power supply is a good size for a gaming PC (depending on your specific build). However, it’s not the only option. For example, if your build requires components that suck up a lot of power (like overclocking your CPU), then you might want to go with a 1200 or 1500 watt power supply.
The best way to determine how much wattage you need is by reading reviews and checking the list of components needed in your build. This will give you an idea of how much electricity each component needs so you can determine what size power supply is right for you.
It’s also important to consider where you’ll be plugging in your computer. If there are multiple plugs available at the spot where you plan on building your rig, then it would make sense to invest in a larger power supply that could support all those outlets rather than buy one with less watts and have to worry about changing the cord when switching between plugs.
