Server-grade 800 W redundant unit
The Supermicro PWS-801-1R is an 800 W redundant power supply built for rackmount servers. It fits 1U and larger chassis that accept the 13.58" x 2.99" x 1.58" form factor and need hot-swap capability.
Single +12 V rail at 66 A
The unit delivers its full 800 W through a single +12 V rail rated at 66 A with a 5 V standby output of 4 A. All DC power comes from that one rail, so the total 12 V current budget is the hard limit for every component in the system.
Not for non-redundant or lower-wattage builds
Buyers who need a stand-alone supply without hot-swap redundancy or who are building a system that draws less than 800 W will not use the redundant architecture this model provides.

Questions about this item
Should I choose the 800W model or look for a different capacity?
The PWS-801-1R delivers 800W total output with +12V at 66A and +5VSB at 4A, matching Supermicro redundant server chassis designed for this wattage.
What does the 800W rating mean once installed in a server?
It provides up to 800W continuous power, with the +12V rail supplying 66A for CPUs and GPUs while +5VSB delivers 4A for management controllers.
Which power interface standard does this supply use and what does it limit?
It uses the SSI-EPS redundant form factor with standard 24-pin and 8-pin EPS connectors, limiting use to compatible Supermicro server backplanes.
