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.

Questions about this item

How much heat and noise does the 180W PS-4181-7 produce when running continuously?

The 180W PS-4181-7 is a small-chassis server supply measuring 19.8 × 8.5 × 5.2 cm; its compact form factor means the internal fan must move air through a tight space, so expect audible airflow under sustained load.

Which cables or connectors must my system already provide for the PS-4181-7 to work?

Your motherboard needs a 24-pin ATX socket and a 4-pin CPU power header, while drives require SATA power ports and the slim optical bay uses the notebook optical-drive connector built into the unit.

Will the PS-4181-7 fit and power an older HP small-form-factor chassis that used the 793073-001 or 797009-001 part?

Yes — the PS-4181-7 matches the 19.8 × 8.5 × 5.2 cm dimensions and the 24-pin, 4-pin CPU, SATA and notebook optical-drive interfaces of those original HP SFF power supplies.
