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.
NZXT C650 Gold
8.3 / 10 Expert Rating
A solid 650W Gold-rated ATX unit for a mainstream single-GPU gaming build, held back only by the usual mid-tier compromises on cabling and OEM sourcing.
