This 310W SFF switching power supply unit is a fully compatible replacement power module designed exclusively for HP business small form factor desktops, including ProDesk 280 G3, 288 G3, 282 G3 SF and ProDesk 400 G4. It replaces the original PCG007 power supply and cross-compatible spare part numbers 901772-004 and 937516-004, also interchangeable with DPS-310AB-1A series power units.

It adopts an exact OEM wiring layout with dedicated 4+4pin EPS CPU power, flat 7pin motherboard control connector and 6pin peripheral power cable, eliminating adapter or rewiring needs during installation. The compact metal casing retains the original mounting hole positions for quick swap during IT fleet maintenance and desktop repair.

Certified 80 Plus Gold energy efficiency greatly reduces idle power draw and heat generation during long-hour office standby and document processing. 100-240V full-range AC input fits all global office mains grids without voltage transformers.

Built-in multi-layer intelligent safety protection instantly cuts off power output once overload, short circuit or excessive internal temperature is detected, preventing permanent hardware damage to mainboards, memory modules and hard disk arrays. The variable-speed cooling fan adjusts rotation speed based on internal heat load to minimize idle running noise.

Every PSU undergoes strict full-load aging testing before shipment to guarantee consistent low-ripple 12V output stability. Optimized honeycomb ventilation structure accelerates heat dissipation, making it ideal for corporate offices, school labs and stable round-the-clock business computing environments.
