Corsair HX1500i (2025, ATX 3.1)

Cat. no. psu-corsair-hx1500i

Curator note

A 1500 W ATX 3.1 unit that covers about three power-limited cards by this site's estimate. Its two 12V-2x6 cables are the connectors for RTX 4090 or 5090-class cards, and five 8-pin PCIe connectors cover older cards such as the RTX 3090; the 12V-2x6 cables use the same sockets as the 8-pin ones, so the two counts can't all be used together. Corsair rates it at 1500 W from 115 V up but 1200 W on 100 to 115 V input. At 200 mm long it fits most ATX cases.
