Choosing the best power supply for your system is absolutely necessary, as it plays an important role in the reliability and longevity of your PC. The power supply unit provides power to all your expensive components, so the best power supply should have the ability to back up your parts in the event of a power surge or failure.
The importance of proper nutrition should never be underestimated. When choosing parts for your gaming PC, the power supply you choose today will determine how long your PC will last. Cheap PSUs aren’t worth it, so it’s a good idea to spend a little more and be safe.
Best Power Supply Units for Gaming PCs
1) Corsair AX1600i
High wattage power coupled with the highest power rating a PSU can get (Titanium) makes this a brilliant choice for a PSU. Apart from its high efficiency, it has a unique LAMBDA-A rating, which certifies it for low-noise output as you have the option to disable/enable a semi-passive fan mode via Corsair Link software.
2) XPG 650W core reactor
This power supply unit can easily power a powerful gaming PC with high-end GPU and power-hungry CPU. It’s a compact PSU with a top-mounted 120mm fan and a second best efficiency rating from Gold. As a modular power supply, it contains all the cables and connectors you might need, with enough length for all PC sizes.
3) Cooler Master V750 Gold V2
The Cooler Master V750 is a cold power unit, with the highest temperature up to 47 degrees Celsius. With an excellent efficiency rating from Gold and being fully modular, this is the PSU to go for if 750W is the amount your PC will need.
4) Corsair CX450
The Corsair CX450 is the best cheap PSU if you’re looking for a low-power PC build. Although it is not a modular design, it has all the cables and connectors necessary for the usual construction. It’s also a compact PSU that will fit into smaller cases, although you’ll have to tuck away the extra cables.
5) Fractal Design Ion SFX 650 Gold
With a gold rating, modular design, 10-year warranty, and long flex cables, the ION SFX houses a 120mm fan. Thus, the power supply can become noisy under heavy load.
6) Seasonic Prime Titanium TX-1000
Seasonic’s Prime Titanium is a more expensive choice, but it guarantees you all the conveniences. Being completely silent in semi-passive mode, this is a power supply that will last you many years with a 12-year warranty.
7) shut up! Dark Power Pro 12 1500W
With a maximum output of 1500W, this PSU can power a beast of a PC with multiple GPUs installed. A modular design with wrapped cables will help your build look minimal and sleek. There is also a 1200W version if you don’t need the extra 300W for your PC.
Before buying a power supply, you need to calculate how much power your PC will need. A power supply that can supply less than your power consumption will shut down the PC as soon as it overcurrents, damaging components. While there’s nothing wrong with buying a PSU that can handle more power consumption than necessary, overspending is likely.
Another factor that can change your choice is if a power supply is modular. A modular power supply allows you to plug in only the cables you need, while a non-modular power supply comes with cables attached.
The efficiency of a power supply determines the electricity consumption. If a 500W PSU is rated at 80% efficiency, that means it will draw 625W from the mains as 600W/0.8=625W, while the remaining 125W is simply wasted and dissipated as heat, which is where cooling comes in.
Considering all these factors, you can make your decision and purchase the best power supply for your build.
