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.
Seasonic Core GM-650
7.6 / 10 Expert Rating
The cheapest legitimate route to 80 PLUS Gold in Seasonic's lineup, good for mainstream builds that don't need full modularity.
