Verdict
Antec HCG1000 Gold Extreme
8.3 / 10 Expert Rating
A solid 1000W Gold-rated ATX unit for an RTX 4080/4090 or RTX 5080/5090-class high-end gaming build, held back only by the usual mid-tier compromises on cabling and OEM sourcing.
XPG Core Reactor II 850W
8.2 / 10 Expert Rating
Core Reactor II is the first ATX 3.1-certified unit in this batch, so it carries the tightened 12V-2x6 transient spec, a meaningful reassurance for anyone running a power-hungry RTX 50-series card.
