What to look for

  • 80 PLUS Gold certification (Bronze if your budget is tight).
  • Modular or semi-modular: makes cable management easier.
  • Make sure it has the PCIe connectors your graphics card needs: check the specific model.

How it's calculated

Peak processor power + graphics card power + 100 W for the rest of the system. The minimum adds 20% and the recommended adds 40% headroom, rounded to a standard size. The processor's peak power is an estimate (1.35 × its TDP). This is a rough estimate: also check the graphics card manufacturer's recommendation.
