HP 400 G3 SFF replacement PSU

This 180 W unit is built for the HP 400 G3 small-form-factor desktop. It matches part numbers 793073-001, 797009-001 and 848050-003 so the swap is direct. Buyers restoring or servicing that chassis get the exact power rating the system expects.

Standard ATX cabling fits the proprietary connector

The supply uses the native pin-out for the 400 G3 motherboard, so no adapter is required. It frees the builder from hunting a rare OEM spare. Systems needing higher wattage or a different form factor cannot use this unit.

Questions about this item

What sustained load can the 180 W PS-4181-7 deliver before hitting its thermal limit?

The unit is rated for 180 W continuous output; sustained loads above that level will trigger protection and shut the supply down.

How much heat does the PS-4181-7 add to the chassis during all-day operation?

At full 180 W load the supply dissipates its losses as heat inside the HP 400 G3 SFF case, so plan airflow for that thermal contribution.
