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.
FSP Hydro K PRO 750W
7 / 10 Expert Rating
A solid 750W Bronze-rated ATX unit for a popular RTX 4070 Ti / RTX 5070-class gaming build, held back only by the usual mid-tier compromises on cabling and OEM sourcing.
