The PSU controls the system’s power supply for optimal performance and protection, making it the heart of anygaming PC build.
You, therefore, want to pick the best PSU you may get for your money in terms of wattage, modular design, and energy efficiency rating.
Most gaming builds will need power ranging between 450 to 650 watts unless you use a powerful GPU like the recently released RTX 4090.
But picking an 850W PSU ensures it reliably supplies your system with all the power it needs while making room for future upgrades.
I have handpicked the best 850W PSUs for gaming for all budgets in this guide. It includes both ATX and SFX to cater to all builders.
Best 850W PSUs for Gaming
Corsair RM850x—Overall Best 850W PSU for Gaming Builds
The Corsair RM850x power supply is highly regarded by most builders. It’s fully modular and has an 80+ Gold efficiency rating.
My favorite feature about it is the zero RPM fan mode that offers near-silent operation at low to medium loads.
The Corsair RM850x affords a high-efficiency operation for lower power consumption, less noise, and cooler temperatures.
EVGA 850 BQ—Best Budget 850W PSU for Gaming Builds
The EVGA 850 BQ is a semi-modular PSU that offers a great balance between price and performance.
It has an 80+ Bronze efficiency rating with a tried and tested efficiency of over 85% under typical loads.
The EVGA 850 BQ PSU is a perfect choice for builders who want great value for their money. But you may get the much better EVGA 850 BQ 80+ Gold for a few extra bucks.
