10 Best Power Supply Units for PC Gaming

PSU is one of the building blocks of a desktop computer. Without a proper power supply unit, you can not make, let alone run, a PC. Here, we will point out the 10 best power supplies for PC gaming from the sea of high-quality PSUs. They are made with high-quality components that provide optimal protection against sudden power surges and fluctuations. Keep in mind that you must use at least an 80 Plus Bronze-rated power supply in a gaming system.

What to Check Before Buying the Best Power Supply?

There are some points you should check to get the best PSUs for gaming PCs. You have to check these features and points before making any buying decisions. These are valid for all the PSUs for desktop computers available in the market. We have tried to include the most important things you should check before getting a new PSU.

Size: You must know the size of the PSU you require before scrolling down on websites and wandering in the local shops. There are ATX, SFX, and a few other sizes available. The OEM-built ones are not expected as they are proprietary built and certainly not suitable for general and custom PC users. Almost all types of casings, from full tower to mini-ITX size ATX sized PSUs, have the most clearances.

Wattage Capacity: This is a crucial point to pay heed to. There is a belief that the more the Watt is capable of maximum output, the better. This is certainly not true; yes, you can buy a large-capacity PSU for future upgrades.

But it would help if you did not overdo it, as it will cost more and does not bear any additional value. You must check your CPU, motherboard, and GPU power requirements. For a single GPU-based PC, a 650-750-watt PSU is more than enough in most cases.

If you have a mid-tier GPU, we suggest you buy a PSU that has a capacity of between 550 and 650 watts. You will have some of the best PSUs for PC gaming at that range at affordable prices.

Efficiency Certifications: Power-efficient certification is necessary to know about the overall quality of a PSU. The way a PSU is rated goes through a lot of processes and expectations. PSUs are supposed to provide continuous power of at least 80 percent of the advertised wattage. The rating starts from 80 Plus white to Platinum.

It is better to choose one of the best power supplies for PC gaming from at least 80 Plus Bronze. The 80 Plus Gold is the sweet spot. Most of the GOLD-grade PSUs are made with high-quality components and come in an affordable price range. For budget gamers, 80 Plus Bronze/Silver-rated PSUs are more than enough if that is from a well-known brand.

Budget: Like it or not, the budget plays a huge role in making any purchasing decisions. To buy one of the best PSUs for gaming, you must get the most feature-enriched one with an extended warranty period.

If you are tight on a budget, try getting a large-capacity PSU from the Bronze or Gold-rated tier. You can easily find 650w or 750w of Bronze-rated PSUs under 80USD from any good brand.

If the budget is not a problem, you can surely get the best PSUs to your satisfaction. Thermaltake Toughpower Grand RGB 1050W is expensive and has solid built quality with an extended warranty period. Although, this might seem overkill for budget builders.

Warranty: This is an essential point you have to check, and the more warranty a company provides, the better. You will find that GOLD or more excellent-rated power supplies for gaming PCs are entitled to 10 or more years of warranty. A bronze-rated power supply unit with a 5-year warranty will also do the job. You might probably upgrade or change your PC components every 3/4 years.

Modularity: There are different types of power supplies for gaming available in the market. Some come with detachable ports and cables, which are known as modular PSUs. The fixed ported ones are non-modular type PSUs. You will find these at a relatively low price. You can choose any of them according to your preference.

PCIe and EPS connectors: This is another critical factor you must check before buying a new PSU. PCIe connectors and EPS connectors are the reasons you should buy a high-quality PSU, so check your requirements. It is always better to get a PSU with additional connectors. That way, you will have an easy path to upgrade in the future.

Some PSU comes with more than 1 EPS connector with 8pins. They tend to be pricier. You can buy them, but you should not spend more if you need that additional feature. Also, check the voltage and ampere ratings for the PCIe and EPS connectors.

Where to Find the Best Power Supply?

You will find PSUs for gaming PCs in almost all the computer stores. It is a fundamental component, so it is widely available. If you are looking for the best power supply for PC gaming, you can easily buy it at online shops, such as your local Amazon, NewEgg, eBay, PCPartPicker, Walmart, etc. They even provide attractive discounts and price cuts on high-quality PSUs from time to time.

You have to choose the suitable power supply for your gaming PC according to the system’s overall needs. If you choose a well-known brand with at least 80 Plus gold or bronze, that is good to go.

Also, you have to keep in mind that 80 Plus certification certifies the efficiency performance. You can choose from EVGA, Thermaltake, Corsair, Seasonic, etc. Also, look out for package deals with PSUs; they can save you some bucks.

Besides, its 80PLUS Bronze Certified functions under the typical loads, which will ensure around 85 percent efficiency. Also, its efficiency and maximum power are increased with the High Amperage Multi-Rail Design.

EVGA 500 B1

This 500w rating PSU also comes with a few drawbacks as well. Unlike most other PSUs, it provides only 3 years of warranty, which is quite disappointing. Also, it’s a non-modular PSU.

But still, it can perform perfectly for regular users and medium graphics gamers. However, this protective PSU offers Over Voltage Protection, Under Voltage Protection, and Over Current Protection. So, it must be a good pick if you don’t have too many functions to use.

And an anti-vibration mounting system will be there to protect the Riings. It also has the best Japanese capacitor with temperature protection of 105°C. Its completely modular design provides the best performance.

Thermaltake Toughpower Grand RGB 1050W Platinum

About the ventilation system, I have a lot to say. Its side ventilation design is very protective, and you will also love its concentrated compression fan blade. Still, the fan profile is not satisfactory if you plan heavy use like mining or extreme overclocking.

Besides, the lack of over-temperature protection can be a cause for people to stop thinking about it. Still, the overall performance of the PSU with the LLC converter is appreciated, and the 10 years of warranty will definitely make you assured.

This fully modular power supply unit also comes at a comparatively affordable price and provides a long-term warranty. This compact-size power supply unit also works silently, and even under excessive load, it won’t sound at all. However, you may not like the function of this PSU’s transient response.

Its response is only at 3.3V, and it could be developed for sure. Also, two EPS connectors in this power supply unit are on the same cable, and that can be an effective drawback. Still, this PSU performs incredibly well in gaming and overall performance.

Regarding the performance, it also shows its excellence. The company even ensures the best analog platform with this unit. And still, after so many years, it is known to be the strongest Titanium-class PSU.

Seasonic Prime Titanium TX-1000, Best Power Supply for PC Gaming

I would also like to mention the price as well. Remember that you won’t get the great thing at a low price very often. As usual, it is pretty much pricey, and you must understand the reason for that. The LAMBDA-A++ badge of this PSU will keep an eye on its noise output for sure.

Also, the cooling fan of this PSU measures 135mm, and the ventilation system is perfect. But you may not like the short peripheral connection distance of it. Otherwise, it can be the ideal match for your next build.
