WMtec PS-4181-7 180W server power supply 793073-001 797009-001

Small-Chassis 180 W Server PSU

The WMtec PS-4181-7 is a 180 W power supply designed for small-form-factor server chassis. It fits systems that require the HP 793073-001 or 797009-001 part numbers. The unit delivers power through a 24-pin motherboard connector, a 4-pin CPU connector, SATA drive connectors and a notebook optical-drive connector. It is intended for administrators replacing a failed unit in compatible HP small-chassis servers.

Steady 180 W Delivery

Under sustained load the supply maintains its rated 180 W output without relying on short-term peak headroom. The 24-pin, 4-pin and SATA rails share the same power budget, so total draw across all connectors must stay within the 180 W limit. Systems with multiple drives or higher-wattage CPUs may exceed this budget during prolonged workloads. Builders needing more continuous power for additional components should consider a higher-capacity unit.

Compact Cooling in 19.8 × 8.5 × 5.2 cm

The 19.8 × 8.5 × 5.2 cm enclosure uses an internal fan to move air across the components during normal operation. Acoustic output and power draw at the wall will vary with the actual load placed on the 180 W rating. No further thermal, noise or efficiency specifications are provided by the manufacturer.
