Product identity

The WMtec PWS-1K21P-1R is a 1U redundant server power supply rated at 1000W on low-line input and 1200W on high-line input. It carries 80 Plus Gold certification with a peak efficiency of 92 percent. The unit uses a gold-finger output connector and is designed for hot-swap replacement in compatible Supermicro chassis. It targets system integrators and data-centre operators who need fault-tolerant power in a compact rack form factor.

Build integration

The supply measures 76 by 40.4 by 336 millimetres and slides into the redundant bays of supported Supermicro systems including the CSE-216E26-R1200LPB, CSE-745TQ-R1200B, CSE-826E16-R1200LPB, CSE-836 and CSE-846 families. At 100 to 140 volts it draws up to 11.5 amps for 1000 watts output; at 180 to 240 volts it draws up to 8 amps for 1200 watts output. The gold-finger interface connects directly to the chassis backplane, freeing internal space otherwise used by cable harnesses.

Upgrade context

This module replaces a failed or end-of-life redundant unit in the listed Supermicro servers, restoring N+1 redundancy without chassis modification. The jump is worth it when an existing supply shows degraded efficiency, audible fan wear or when a platform refresh demands the higher 1200 watt high-line capacity. It is not for builders needing ATX or EPS cabling, non-redundant desktop use, or chassis outside the specified Supermicro model range.

Highlights

  • 1U form factor fits dense racks with 76 x 40.4 x 336 mm dimensions

  • 80 PLUS Gold certified reaching 92% peak efficiency
  • Hot-swap redundant design supports continuous server uptime
  • Gold finger output connects directly to compatible Supermicro chassis

Questions about this item

Will the 1000W rating hold steady at 11.5 A input on a 100 V circuit?

At 100–140 V the unit draws 11.5–8 A to deliver 1000 W; above 140 V it switches to the 1200 W range.

How loud and hot does the 1U redundant PSU get when running 24/7 at full load?

The 80 Plus Gold design peaks at 92 % efficiency, so waste heat and fan speed stay lower than non-Gold units at the same 1000 W or 1200 W output.

Which Supermicro chassis already have the gold-finger backplane this PWS-1K21P-1R slides into?

Compatible models include CSE-216E26-R1200LPB, CSE-745TQ-R1200B, CSE-826E16-R1200LPB, CSE-836A-R1200B, CSE-836E16-R1200B, CSE-836E26-R1200B, CSE-846A-R1200B, CSE-846E16-R1200B, CSE-846E26-R1200B, and CSE-846TQ-R1200B.
