Seasonic PRIME TX-1600 (ATX 3)

Cat. no. psu-seasonic-prime-tx-1600

Curator note

A 1600 W Titanium ATX 3 unit that covers about three power-limited cards by this site's estimate. Two native 12V-2x6 cables are the connectors for RTX 4090 or 5090-class cards, and six 8-pin PCIe connectors cover older cards such as the RTX 3090. Seasonic rates the full 1600 W from 115 V input. At 210 mm it is longer than most ATX units, so check the case's PSU clearance; it is expensive.
