Verdict

ASUS ROG Thor 1200W Platinum II

8.8 / 10 Expert Rating

A best-in-class 1200W Platinum-rated ATX unit for a workstation or multi-GPU build with serious headroom, held back only by its premium price.

Corsair RM650x

8.2 / 10 Expert Rating

The 650x is Corsair's mainstream sweet spot: quiet Zero RPM idling, a 10-year warranty, and enough headroom for a mid-range gaming build without overspending on wattage you won't use.
