14-Pin 180W PSU Replacement

The Ruth's sister HK280-22FP is a 180W internal power supply unit built for compatible desktop and server chassis. It delivers power through a single 14-pin motherboard connector and a 4-pin CPU connector. Active PFC corrects the power factor across the 100-264V input range. Four SATA ports are provided for drive connections.

Replaces HK280-22FP and listed compatibles

This unit replaces power supplies carrying model numbers PCB038, PCB037, HK280-23FP, HK280-25FP, PE-3181-01, PS-3181-03 and HK280-22PP. It is also specified for systems identified as M6300, M6308, M6408, M6475, M4800N, TS140, TS230, M8400, M8500, A6800T, M4500, M4550, M4600, H5050, H5055, D5050, F5050, T530, M2610N, T4900, 6800, 5050, 4900 and 75. The jump is worth it when the original 180W supply has failed or shows instability.

Verify 14-pin motherboard and 4-pin CPU fit

Before ordering, confirm the motherboard uses a 14-pin main power socket and a 4-pin CPU power socket. Check that the chassis can accommodate a non-modular unit measuring 150 by 86 by 100 millimetres. Ensure the four SATA connectors match the drive count required. No PCIe graphics power connectors are present on this model.

Questions about this item

Will the 14-pin motherboard connector and 4-pin CPU connector fit inside a 150 mm by 86 mm by 100 mm chassis?

The unit measures 150 mm by 86 mm by 100 mm and provides a 14-pin motherboard connector plus a 4-pin CPU connector, so it fits that exact form factor.

Which step is most often missed when installing this non-modular 180 W power supply?

Connect the 14-pin motherboard cable and the 4-pin CPU cable before securing the PSU with screws; forgetting the CPU 4-pin is the common oversight.

How often should the active PFC circuit be checked on this HK280-22FP unit?

No scheduled PFC check is required; replace the supply only if voltages drift or the system becomes unstable.
