KHACHIMO 280 G4 Pro 600 800G3 4Pin 310W Power Supply

Compatible Replacement PSU

This 310W ATX unit fits HP 280 G4 Pro 600 and 800 G3 desktop chassis. It matches the D17-310P1A, L07305-002, D16-250P2A, D16-180P1B, PCH023, PCG007 and D16-180P1A part numbers. Builders repairing or upgrading those specific models can install it directly. It is not for systems that require a higher wattage rating or a different form factor.

4Pin Power Connector

The cable harness uses a 4-pin main power connector that mates with the motherboard socket on the listed HP platforms. Pin count and keying must match exactly or the board will not receive power. Verify the existing connector before ordering because other HP desktops use 6-pin or 24-pin layouts instead.

Gold Efficiency and Quiet Operation

80 PLUS Gold certification means the unit wastes less electricity and runs cooler than lower-rated supplies. Zero RPM fan mode stops the fan completely at low and medium loads for silent running. Resonant LLC topology with DC-to-DC conversion delivers stable voltage and reduces coil whine. Modern Standby support enables faster wake-from-sleep times.
