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.
Gigabyte UD850GM PG5
8 / 10 Expert Rating
A modern, well-specced ATX 3.1 Gold unit for Gigabyte-themed builds, docked slightly for being a newer, less field-tested platform.
