Supermicro PWS-1K28P-SQ 1280W hot-swap platinum power supply

SKU CH-8C0X-HG5W2 MPN PWS-1K28P-SQ

A 1280 W hot-swap server power supply with 80 Plus Platinum efficiency and single-fan cooling

  • 1280 W output supports dense server configurations
  • 80 Plus Platinum efficiency reduces energy cost at 180–240 V input
  • Hot-swap design enables replacement without downtime
  • Single fan cooling maintains thermal control
  • Tested working units verified for immediate deployment

1280W hot-swap platinum server supply

This Supermicro PWS-1K28P-SQ is a 1280 watt redundant power module built for 1U to 4U rack servers. It carries 80 Plus Platinum efficiency and supports hot-swap replacement without shutting down the system. A single fan provides cooling inside the compact chassis. The unit has been tested and is ready for deployment.

Suited for rack builds needing redundant 1280W power

It fits administrators upgrading or repairing 1U, 2U, 3U or 4U servers that accept this form factor and require platinum-grade efficiency. The hot-swap design allows maintenance while the server stays online. Builders who need a different wattage, a non-redundant form factor or an input range outside 180-240V should look at other models.

180-240V AC input range decides fit

This supply operates only on 180 to 240 volt mains at 50 to 60 Hz and will not start on lower-voltage circuits. Confirm the facility power matches this range before purchase. No other single specification determines whether the unit will work in a given rack.

Questions about this item

What rack-mount chassis depth and form-factor slots does the PWS-1K28P-SQ require?

The supply fits 1U, 2U, 3U and 4U server bays and needs a redundant hot-swap backplane that accepts its 1280 W platinum module.

Can I mix this 1280 W platinum unit with an older lower-wattage supply in the same redundant pair?

No — redundant operation requires matching wattage and efficiency, so the second bay must also hold a 1280 W 80+ Platinum module.

Which LED or status signal confirms the PWS-1K28P-SQ is delivering power after installation?

A green front-panel LED on the unit lights when the 180-240 V input is present and the 1280 W output is active.
