Verdict
Antec HCG850 Gold Extreme
8.1 / 10 Expert Rating
A well-priced step below the HCG1000 with the same ATX 3.0 platform and 10-year warranty, right for RTX 4080-class builds.
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.
