Platinum efficiency for 1U servers

The Supermicro PWS-501P-1R is a 500 Watt internal power supply certified to the 80 PLUS Platinum standard. It targets system integrators and IT teams deploying dense 1U rackmount servers where high conversion efficiency reduces operating cost and heat output. Its compact form factor suits space-constrained chassis that require reliable, continuous power delivery.

Fits 1U redundant or single-slot bays

This unit installs directly into a standard 1U power-supply bay and provides active PFC for clean input current. It frees internal volume for additional compute or storage modules by keeping the power footprint minimal. Builders needing higher wattage or non-redundant ATX form factors should look elsewhere, as this model is purpose-built for the 1U 500 Watt Platinum class.

Questions about this item

What is the first limit reached under sustained load with this 500 Watt unit?

The 500 Watt continuous rating is the ceiling; 80 PLUS Platinum efficiency keeps waste heat low so thermal protection rarely trips before the power limit.

How does the 80 PLUS Platinum rating affect noise and heat during all-day operation?

Platinum efficiency means less waste heat, so the fan can run slower and quieter while the supply delivers full rated power continuously.
