  • 80 Plus Platinum efficiency reduces energy waste

Replacement PSU for HP ProDesk SFF

This 200 watt unit replaces the original power supply in HP ProDesk 400 600 800 G1 and G2 small form factor desktops. It matches the listed part numbers and model numbers from the manufacturer. The AC input range covers 100 to 240 volts at 50 to 60 hertz. Maximum output power is rated at 240 watts.

Direct swap with three keyed connectors

Installation uses the existing mounting points and three keyed cables: one six pin, one six pin and one four pin. The connectors only fit one way so polarity errors are unlikely. The main risk is ordering the wrong revision for a chassis that needs a different pinout or wattage. Always verify the exact part number on the old unit before fitting.

Check your current label before ordering

Confirm the sticker on your existing supply shows one of the compatible part or model numbers supplied in the data. Ensure the chassis is the small form factor version and not a tower or micro tower variant. The replacement is rated for 200 watts continuous output so systems upgraded with high power graphics cards may exceed its capacity.

Questions about this item

How do I verify the 200W power supply is working after installing it in my HP ProDesk 400 G1 SFF?

The system should power on normally, the PSU fan should spin, and the motherboard LED should light up. No error beeps or shutdowns under load confirm the 200W unit delivers stable DC output through the P1 6-pin, P2 6-pin and P3 4-pin connectors.

What comes in the box with this myVolts 200W PSU and what must I source separately?

The package contains the 200W power supply unit only. You must reuse the original AC power cord, mounting screws and any proprietary HP cable adapters from the old PSU, as none are included with this replacement unit.

Which compatible part number should I match — 796349-001 or 796351-001 — for my HP ProDesk 600 G2 SFF?

Both part numbers are listed as compatible. Check the label on your existing PSU; if it reads 796349-001 or 796351-001 (or any other number in the compatibility list), this 200W unit will fit and function correctly.
