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.
Silverstone ST75F-PT
8.4 / 10 Expert Rating
A genuinely efficient Platinum-rated ATX PSU for buyers who want Silverstone's SFX-L build quality without the compact form factor.
