Top 11 Power Supply for Gaming PC Reviews in 2023

When you construct a gaming PC, you use the best components for your system so that the gaming experience can be smooth. Starting from CPU and GPU to RAM and SSD, you need to have high-end components so that there is no lagging and crashing issue when you play high-graphics games. Along with these components, you should pay attention to the power supply unit(PSU) of your gaming PC.

The power supply unit ensures a steady flow of current to all the different components so that they function properly. Most importantly, the power supply of your gaming PC ensures an efficient flow of current so that there is no wastage of energy. There are different types of power supplies available in the online world dedicated to gaming PCs. Before you purchase a power supply unit for your gaming PC, you should watch out for the following parameters.

  • Output Wattage – The most important parameter to check while purchasing a power supply for a gaming PC is the output wattage rating. You should already have a rough estimation of the maximum power needed by your gaming PC. You should always opt for a higher power supply unit so that there is no dearth of supply of energy as demanded by different components. Some of the common output wattages of power supplies for gaming PCs are 550W, 750W, and 850W.
  • Power Supply Design – When you check out the power supplies for gaming PCs, you will come across different power supply modular designs such as non-modular, semi and full modular. A full-modular design lets you remove cable connections as per your requirements. On the contrary, non-modular power supply units have non-removable cables. Depending on your requirements and budget, you have to choose accordingly.
  • Efficiency – For any power supply, efficiency plays a key role as it determines the consumption of electricity as well as the reliability factor. A power supply with high energy efficiency will consume less electricity as most of the amount is utilized. For example, a power supply of 80% efficiency means it wastes 20% of electricity as heat. Besides, power supplies for gaming PCs have certain efficiency standards such as gold and bronze. A gold power supply is more efficient than a bronze power supply of the same wattage.

Apart from these, there are multiple factors a buyer has to check in order to purchase the perfect power supply for his gaming PC. That is why we have written a detailed Buying Guide where you will find all the buying parameters to check. You can use those parameters to compare and choose the best product. To make things even easier, we have handpicked the best power supplies for gaming PCs for your consideration. We have outlined their features, benefits as well as negative points for better understanding.

Buying Guide for Best Power Supply for Gaming PC 

A power supply is an equally important component for a gaming PC as the rest of the components that make the PC powerful for high-end games. Hence, you should pay attention to the details while purchasing a power supply for your gaming PC. You must have seen that there are different types of power supplies for gaming PCs available.

Without the proper knowledge, you can easily end up with an unsuitable power supply for your gaming PC even though the power supply is of high quality. We have selected the best power supplies, but you have to choose the perfect one from the list. Hence, you should go through the following buying guide so that you can pick the best suitable power supply for your gaming PC easily.

1. Output Wattage

The first thing you notice in a power supply unit is the output wattage. You will find various power supply units for gaming PCs with different output wattage such as 550W, 750W, and 850W. The higher the output wattage, the more power it can supply to the components. However, you need to choose a power supply based on your power requirements. If your gaming PC needs around 400W power, a 550W PSU will suffice.

Therefore, you need to have an idea of the power requirements of your gaming PC based on its components. Ideally speaking, if you have a budget gaming PC, 550W PSU is enough. If you have a high-end gaming PC, a 750W PSU will suffice. If you have dual graphics cards on your PC, you have to opt for an 850W power supply. However, you can keep some headroom with a higher power supply than requirements for future upgrading of components.

2. Power Supply Design

There are mainly three power supply designs available in the market. They are non-modular, semi-modular and full modular power supply designs. In a non-modular power supply, the cable connections come fixed, and they are non-removable. On the contrary, you can remove the cable connections in a modular power supply as per your requirements.

Coming to a semi-modular power supply, you can remove selected cable connections. The non-modular power supply is cheaper in comparison to semi-modular and full-modular PSUs. Gamers who have transparent glass cabinets, they opt for a modular power supply so that they can remove unnecessary cables so that the cable organization could be better.

3. Efficiency

The efficiency of the power supply for gaming PCs matters a lot. You do not want to buy a power supply that wastes power and generates too much heat. To make this easy to understand, power supply units come with efficiency ratings. A PSU with 80% efficiency converts 20% power into heat which goes into wastage. Naturally, you should opt for a power supply with higher efficiency.

You should be aware of the fact that there are metallic codes assigned to power supplies for the buyers to differentiate the efficiency of power supplies. The gold power supplies are more efficient than bronze power supplies even though their percentage of efficiency mentioned is the same. You should opt for a PSU that has 80+ certification in power efficiency.

4. Connections

Since a power supply unit ensures proper power distribution in the components of the gaming PC, you should check for the connections that are possible. The most important connector is the 24 PIN cable that powers the entire motherboard. Additionally, there are 8 PIN CPU and 6 PIN GPU cable connectors.

Generally, the 24 PIN should suffice but there are motherboards that require CPU and GPU connectors. Moreover, it is useful if you have extra connectors on your power supply which you can use in future time when you attach different expansion cards on your motherboard. That is also why you should opt for a fully modular power supply so that you can attach and detach cables as and when required.

5. Warranty

Warranty plays a major role when it comes to power supply units. You should not purchase a PSU without any warranty. A power supply can get damaged but to over voltage, over power and short circuit. If a company has confidence in its products, it gives a considerable warranty. For power supplies, you should watch out for 3-5 years of warranty at least. However, there are several brands that offer 10 years of warranty. The higher the warranty period, the more confidence the company has on its products and the product is likely to be better.

Frequently Asked Questions

1. Do power supplies matter for gaming?

Ans: Yes, power supply is an important component of a gaming PC. Not only should a power supply meet the demand of the components of the system but also efficiently manage power distribution. A high-quality power supply ensures long life for motherboard and other PC components. Moreover, it gives more room to overclock your CPU and GPU for better and faster performance.

2. What power supply do I need for a gaming PC?

Ans: It is difficult to predict the power supply that your gaming PC needs because it depends on the power rating of the components in your PC. The more powerful and high-end your gaming PC is, the higher will be the demand for power supply. Ideally speaking, a gaming PC needs power supply in the range of 550W to 750W.

3. Is a 750W PSU good for gaming?

Ans: Ideally speaking, a 550W power supply is good enough for a regular gaming PC. However, if you have installed two graphics cards on your PC, you will need 750W power supply. Therefore, if you have a powerful gaming PC, 750W is good for a smooth gaming experience. Otherwise, 550W PSU can suffice.


It is crucial to get a proper power supply for your gaming PC so that the components can get the necessary power as required. In fact, some components like CPU and GPU may require additional power for overclocking. In short, the power supply should meet all the demands of different internal components so that the system can deliver more than expected.
