What’s the best power supply for a gaming PC?

Power supplies are an important part of your gaming PC. It’s what will power the other hardware you have, and without a strong power supply, your computer will be slow.

If you want to start building a more powerful machine, then you’ll need to invest in a higher-wattage PSU. This can range from 1200 watts up to 1600 watts or more depending on how much space you have inside your case and how much you want to spend.

Opt for a modular power supply

A modular power supply is a type of power supply that only includes cables for the components in your PC. That means you won’t be paying for cables that you don’t need! This can save you a ton of money, as not all power supply models are modular.

For example, say you were building a gaming PC with an Intel Core i7-8700K CPU and an NVIDIA GeForce GTX 1080 Ti graphics card. With this setup, you would need to use both 6+2 pin and 8 pin connectors on your PSU.

If your power supply didn’t include these connector types, there would be two options: You could purchase a new power supply or cut the connectors off of your old one to convert it into a modular one (which is not recommended).

By opting for a modular PSU, you can avoid having to spend more money or sacrifice parts in order to have all the appropriate connections on your PSU.

Go for a PCIE & EPS power supply

One of the most important aspects of your power supply is its wattage. A PCIE power supply is typically used for motherboards and other PCIE cards, while an EPS power supply is usually found on graphics cards, hard drives, and optical drives.

These two types of supplies are not interchangeable.

If you’re building a high-end gaming PC, it may be worth investing in a PCIE supply. However, if you’re building a cheaper gaming PC with a basic graphics card, then an EPS supply will be more appropriate for your needs.

Some people may opt to use an SLI or Crossfire setup with an EPS power supply as well. For this type of arrangement, the PSU should have at least 600 watts of capacity to account for the increased load on the system.

How many watts do you need for your power supply?

When considering the size of your power supply, you need to take into account the components you’ll be installing in your case and how powerful they are. If you plan on installing a graphics card with two 8-pin PCIe connectors for example, it would take a 750W power supply at least.

The wattage rating of your power supply is important because not only does it tell you how much power is available to your PC, but it will also determine the case size.

If you don’t have enough power supplying to your PC, then the system will crash or not turn on at all. So make sure that whatever components you have installed in your gaming PC can be supported by the power supply before purchasing one!

What size power supply is right for your build?

A power supply is a crucial component of your gaming PC. The right one can make sure everything runs smoothly, while the wrong one could damage your other components. And if you’re looking to save money on your build, it’s important that you don’t buy a power supply that’s too powerful for what you need.

To figure out how much power your PC will need, you have to take into account the amount of watts each component requires. This information can usually be found on the product page or advertised by the company.

To make it simple, though, we recommend going with an 850-watt power supply for most builds. It should be enough to run all of your components without overloading the system or causing any problems.

If you think about it logically, an 850-watt PSU will provide enough electricity for a CPU rated at 100 watts and a GPU rated at 150 watts (some GPUs are more powerful than others). Luckily, there are plenty of power supplies in this range.

What is a power supply?

Before we get going, let’s talk about what a power supply is and why you need one. If you’re building your own PC, you definitely need a power supply. A power supply is essentially the heart of your PC because it provides power to all of the other components. Gaming PCs are more demanding on their power supply than standard PCs. So if you decide to build your own gaming PC, make sure to buy a high-quality PSU that can handle the demands of your system.

The first step to choosing a power supply is figuring out what size it needs to be. You’ll want to make sure that you choose a power supply that has enough wattage for your PC’s components.

A gaming PC can use up to 450 watts of power, which means you’ll need an 850-1000 Watt PSU. You don’t want to skimp on this or your computer will fry. A higher quality PSU might cost more, but it will last longer and provide better protection for the other components in your PC.

Do your research before buying a power supply because there are so many different wattages and options out there! A good place to start is this article that has lots of information about how to choose the right size for your gaming PC: https://www.wikihow.com/Choose-a-Power-Supply

500w power supply for gaming

If you’re building a gaming PC, it’s important to choose the right power supply. There are a lot of things to consider when picking out a PSU for your system, but today we’ll just be focusing on the most important factor: size.

Generally, you’ll want a 500w PSU if you’re building a gaming PC. You could get away with less if you only plan on using one GPU and not overclocking, but it will depend on what you plan on doing with your system.

If your budget isn’t an issue and you don’t mind spending the extra money to ensure that your system has enough power to run smoothly, then by all means go for more powerful PSUs. But for those of us who are looking for something affordable and functional, then 500w should suffice.

What should I look for when buying a PSU?

The first thing you should do before buying a PSU is to figure out how much power your PC will need. This varies depending on what kind of system you’re building. If you’re building a basic PC, you’ll need at least 300 watts. If it’s an advanced CPU and graphics card, you’ll need at least 500 watts.

Next, look for the right form factor. There are vertical PSUs and horizontal PSUs. Vertical PSUs are recommended for small PCs that stay put in one place like desktops or HTPCs (home theater PCs). Horizontal PSUs are more versatile and can be used in any situation.

You should also think about cost-efficiency when choosing a PSU. For example, if you’re looking to build an overclocked PC with multiple hard drives, consider going with an 80+ certified PSU rather than something cheap that might not be able to support your system later down the road.

Choosing the right size power supply for your gaming PC may seem confusing at first, but don’t worry! With these guidelines, it won’t be difficult to find what you’re looking for!

What PSU should I get for RTX 3070?

We’ll start with a simple question: What size PSU do you need for a gaming PC? Well, this depends on the components that you have and your budget. But we’ll go ahead and recommend an 850 Watt power supply.

There are two reasons why this is the best option at this point in time. The first reason is that it provides enough power to your components without overloading. Most gaming PCs require a minimum 500 W of power, which may not be available if you purchase a cheaper power supply.

The second reason is that an 850 W power supply will provide enough headroom for future upgrades. This means that if you want to add additional graphics cards, hard drives, or anything else down the line, there will be enough space to accommodate it.

For example, if you were looking at a 450W power supply, but then wanted to add more RAM or another graphics card in the future, your PSU may not be able to handle those additions and would need upgrading anyway.

If you’re just starting out and building your own computer for the first time, this is the perfect way to start!

How to choose the perfect power supply for your gaming PC

Choosing a power supply can be tough. They come in many different shapes and sizes, and they all have different stats that make them more or less desirable. So, how do you know what size PSU is right for your gaming PC?

▪ You need to figure out the total wattage of your components before choosing a PSU. Use this as a guide to determine which wattage of power supply you need.

▪ Decide whether you want modular power supplies or non-modular power supplies. Modular power supplies mean that you have fewer cables coming out of the back of your machine, which makes it look cleaner. But modular power supplies also cost more money.

▪ Look at the efficiency rating on the PSU to ensure that it will provide enough power without being wasteful (and costing you more money). The higher-rated PSUs are better for your PC because they produce less heat and require less energy to run.

You’ll need a power supply, which usually comes with the case that you buy. You should also look into buying a power supply from a reputable manufacturer, like Cooler Master or Corsair.

The size of your PSU is determined by how much power your computer will require when it’s running. You can find this information on the motherboard for your computer, or in your PC’s manual. Once you have that information, you can use this table to see what size PSU is right for you:

Power Supply Recommendations

200-300 Watt – Entry-level gaming PCs and office PCs

300-450 Watt – Gaming PCs

450-600 Watt – High-end gaming PCs

So, Where Can You Buy a Power Supply?

When it comes to power supplies, there are a lot of options. You can buy them from a store in your city or order one online. There are even ways to build your own power supply if you’re feeling confident (or foolish).

The easiest option for most people is to purchase a power supply from an online retailer. They have tons of options and some great prices, so you’ll be able to find something that suits your needs and budget.

It should also be noted that not all power supplies will work with every single PC build. If you want to know if the PSU that you choose will work with your specific motherboard, graphics card, and so on, then make sure that you double-check the compatibility before purchasing it.

What’s the Difference Between a PSU and a Power Supply Unit?

The PSU is the power supply unit that powers your PC and provides the current it needs. The PSU is a box that you’ll place on your desktop or under your desk, and its job is to convert the AC power from your wall into DC power. That’s why they are also sometimes known as “power bricks.”

When you hear someone talk about their gaming PC, they might refer to their PSU as their “power supply.” It can be confusing since both terms are used interchangeably, but what you want to look for when shopping for a PSU for your gaming PC is how much wattage it has.

You know you need a quality power supply with plenty of wattage if you want to run games like Battlefield 1 at 1080p 60fps without any lag.


What size power supply is required for a gaming PC?

This really depends on the needs of your specific gaming PC. Some gaming PCs require more power than others, and each power supply has different wattages available. It’s important to know what you need before you purchase your power supply in order to avoid wasting money.

How do I know what wattage I need?

The two main factors that affect the wattage of your power supply are how many components (or card) you want to connect and how powerful those components are individually. If you have a powerful graphics card with multiple USB connections for peripherals, for example, then it will require more power than a lesser-powered graphics card with fewer USB connections. The easiest way to determine what wattage you need is by looking at the maximum power output of your power supply. This can usually be found on the box or online under specifications.

Again, this depends on the components you want to use in your system. Generally speaking, if you’re using a CPU with a TDP of 95 watts or more and a graphics card with a TDP of 250 watts or more, you will need to get an ATX power supply with a rating of at least 600 watts.

How do I know I need a big power supply?

As mentioned above, if you’re looking to build a powerful machine, then it’s likely that the power requirements will be higher than with a lower-powered machine. If this is the case, then choosing a more powerful PSU at the beginning may be worth it so that you don’t need to upgrade later on down the line when your needs change and your game graphics get better.


With so many things to think about, it can be hard to know which power supply is right for you.

Luckily, we have put together this guide to help you find the right PSU for your needs.

First, you need to decide on a wattage. As a general rule, the more watts your power supply has, the more capable it will be of powering your PC’s components.
