1U Platinum Power Module

This Supermicro PWS-1K66P-1R is a 1U form-factor power supply module certified 80 PLUS Platinum. It delivers a total output of 1000W or 1600W with a +12V rail rated at 82A and 132A respectively. The unit includes active PFC and PM Bus monitoring for enterprise deployment.

Suited for dense 1U server racks

The 73.0 x 265.0 x 40.0 mm dimensions fit standard 1U chassis where a redundant or hot-swap module is required. Builders needing a full-size ATX unit for tower cases or a lower-wattage module for lighter loads should consider other form factors.
