400W AT Power Supply for HP Z230 Tower

This 400W AT-type power supply is built as a direct replacement for the HP Z230 Tower workstation series. It matches part numbers 704427-001, 705045-001 and 860473-001 for a precise fit. The unit suits IT professionals and repair technicians restoring or maintaining these specific workstations. New condition ensures reliable operation from first install.

Sustained-load behaviour on the HP Z230 platform

Under continuous demand the supply delivers its rated 400W to the workstation's original components without exceeding design limits. The AT form factor aligns with the Z230 chassis airflow path so heat is exhausted normally during long rendering or compute sessions. No extra cooling or wiring changes are required for the supported configuration. Buyers needing higher wattage for upgraded GPUs or additional drives should verify the chassis and motherboard limits first.

Questions about this item

How much heat and fan noise does the 400W unit produce when the HP Z230 Tower runs continuously?

The 400W supply uses a standard AT design with an internal fan; under full load it will exhaust warm air from the rear of the Z230 chassis, and fan speed rises with temperature to keep components within safe limits.

Which power cables must already be present in my HP Z230 Tower for the DPS-400AB-19 A to connect?

The replacement unit plugs into the existing motherboard ATX connector, CPU power header and peripheral leads already routed inside the HP Z230 Tower; no additional cables are required.
