Supermicro PWS-1K81P-1R 1U 1800W 80 Plus Platinum redundant server power supply

Redundant 1U 1800W server power supply

This Supermicro PWS-1K81P-1R is a hot-swap redundant power supply in a 1U form factor. It delivers up to 1800 W of power with 80 Plus Platinum efficiency rated above 90 per cent. The unit accepts 200 to 240 V input at 50 or 60 Hz and is built for mission-critical enterprise servers.

Suited for high-density redundant deployments

It suits data-centre racks that need N+1 redundancy in a single rack unit. Operators who must maintain uptime during module replacement benefit from the hot-swap design. It is not intended for systems that require 200 to 240 V input but cannot accommodate a redundant chassis, nor for environments limited to lower input voltage ranges.

80 Plus Platinum efficiency above 90 per cent

The single specification that decides fit is the certified efficiency exceeding 90 per cent at typical loads. This rating reduces waste heat and operating cost in dense 1U installations. Buyers whose infrastructure cannot meet the 200 to 240 V requirement must select a different power solution.
