1400W Redundant Server Power Supply

The Supermicro PWS-1K41F-1R is a 1400W server power supply built for 1U rackmount chassis. It delivers 1400 watts of continuous power through a single 24Pin main connector. The unit meets 80Plus Gold efficiency standards for lower operating costs. Its front-loaded design simplifies installation and hot-swap maintenance in dense server racks.

Ideal for High-Density 1U Deployments

This supply suits administrators running 1U servers that require redundant 1400W capacity and front-access serviceability. It provides +12V output at 92A or 116A with +5VSB at 6A for standby functions. Builders needing rear-exhaust airflow or non-redundant ATX form factors should look at alternative designs. Systems requiring different voltage distributions or connector layouts will not match this specification.

1400W Rating Defines Compatibility

The single specification that decides fit is the 1400W maximum power rating combined with the 24Pin main connector. Your server backplane must accept this wattage and connector type for the unit to function. Physical dimensions of 12.83 x 4.09 x 1.57 inches determine whether the module seats correctly in the target chassis. Verify both electrical and mechanical requirements before procurement.

Questions about this item

What chassis depth and height does the 12.83" x 4.09" x 1.57" unit require?

The supply fits a 1U slot and needs at least 12.83 inches of clear depth behind the front rail.

How is the 24-pin main connector seated in a front-loaded bay?

Slide the unit in until the latch clicks, then press the 24-pin plug straight onto the motherboard header until it locks.

When should the internal fan be cleaned or replaced?

Vacuum the intake grille every six months; replace the fan if bearing noise appears or airflow drops.
