Supermicro PWS-1K41F-1R 1400W power supply

SKU CH-95MW-FJD09 MPN PWS-1K41F-1R

Delivers 1400 W in a 1U form factor with 80Plus Gold efficiency and dual fans

  • Delivers 1400 W maximum output for demanding server workloads
  • 80Plus Gold efficiency reduces energy waste and operating costs
  • Redundant 1U form factor fits standard rackmount chassis
  • Dual fans provide active cooling under sustained heavy loads
  • 24-pin main connector ensures broad motherboard compatibility

Server power supply 1400W

The Supermicro PWS-1K41F-1R is a 1400 watt server power supply built for 1U rackmount installations. It carries an 80 Plus Gold rating and uses two internal fans for cooling. The unit provides a standard 24-pin main connector.

Suited for high-density server builds

This unit suits administrators upgrading or repairing compatible Supermicro 1U servers that require a 1400 watt Gold-rated module. It is not for desktop PC builders who need ATX form factor or modular cabling. Buyers without a matching server chassis and backplane should look elsewhere.

1400 watt maximum output

The single specification that decides fit is the 1400 watt maximum output power. Your system power budget must align with this limit and the chassis must accept the 1U form factor with 24-pin connectivity.

Questions about this item

Will the 24-pin connector or the dual fans need replacing first under continuous server loads?

The 24-pin connector is a standard ATX interface rated for the unit's full 1400 W output, while the dual-fan cooling assembly handles sustained airflow; neither component has a published service interval, so plan inspection during routine chassis maintenance.

Does the 1400 W rating or the 80 Plus Gold efficiency limit sustained output first?

The 1400 W maximum output is the hard ceiling; the 80 Plus Gold rating guarantees at least 80 % efficiency at typical loads, reducing waste heat but not raising the power ceiling.

How loud and hot do the two fans run when the supply delivers 1400 W all day?

Dual fans scale speed with internal temperature; at full 1400 W load expect elevated but server-typical noise and exhaust heat, while 80 Plus Gold efficiency keeps waste heat lower than non-certified units.
