Supermicro 740W Redundant Server Supply

This 740 watt redundant power supply from Supermicro fits 1U and 2U server chassis that use the common redundant form factor. It provides a single high-current output plus a 5 volt standby rail for baseboard management. The unit is new and rated for continuous operation in rack environments.

Suited for single-socket rack builds.

System integrators populating redundant bays in Supermicro or compatible OEM chassis will find the correct connector keying and airflow direction here. Builders using standard desktop ATX cases cannot mount this supply because the physical layout and connector pinout differ from consumer designs. Buyers who need a non-redundant desktop unit should look elsewhere.

740W maximum power rating

The 740 watt maximum power rating is the primary figure for sizing the supply against the server's total load. With a single main output and 5 volt standby at 4 amps, the unit covers typical single-processor configurations with multiple drives and add-in cards. Dimensions of 2.99 by 1.57 by 14.17 inches and a weight of 2.2 lbs confirm the slim redundant footprint.

Questions about this item

Will the 2.99" x 1.57" x 14.17" housing fit a standard 1U redundant power supply bay?

The 2.99" x 1.57" x 14.17" form factor matches the industry-standard 1U redundant PSU footprint, so it slides into any compatible hot-swap cage.

What is the correct way to seat the PWS-741P-1R so the 740W unit powers on, and what step do installers often miss?

Push the module firmly until the latch clicks into the chassis connector; the common error is stopping when resistance is first felt instead of completing the full insertion.

When should the internal cooling fan be cleaned or the whole 2.2 lb supply replaced to maintain 740W output?

Vacuum the fan intake every six to twelve months; replace the unit if the fan becomes noisy, airflow drops, or the supply fails to maintain 740W under load.
