Supermicro 1000W Titanium Server Power Supply

The Supermicro PWS-1K03A-1R is a redundant 1000 watt server power supply rated at 96 percent efficiency under the 80 Plus Titanium programme. It includes PMBus monitoring and meets RoHS and REACH compliance standards.

Suited for high-density servers needing Titanium

Buyers who require a different wattage or a non-redundant form factor should consider other models. Systems without PMBus support cannot use the monitoring features. The unit is designed for compatible Supermicro chassis only.

Questions about this item

How do I install the PWS-1K03A-1R into a redundant server chassis and what step is often missed?

Slide the module into the hot-swap bay until the latch clicks, then verify the PMBus address is set correctly in the BMC — the address dip-switch position is the step most installers forget.

What maintenance or replacement will the PWS-1K03A-1R need over its service life?

The internal fan is the only moving part; plan to replace it when bearing noise appears, and re-apply thermal paste on the primary MOSFETs during that service.
