Power supply (PSU)

Good8.5/10Mid-range

Corsair is the most common recommendation for a mainstream gaming PSU, with the RMx and RMe ranges widely stocked and well reviewed. Its high-end HX and compact SF units are also strong. Check which revision you are buying, as names carry across generations.

Good at

  • RMx and HX units rank highly on tier lists and Cybenetics
  • 10-year warranty on RMx and HX lines
  • SF-series SFX units are a small-form-factor favourite
  • Stocked by nearly every PC retailer

Weak at

  • Budget CX line is decent, not a standout
  • 2020 SF Platinum recall over a batch of failures
  • Model revisions share names, so check the year
