Direct replacement for ThinkCentre towers

The DoDo DIY PS-4281-02 is a 280 W power supply built to fit ThinkCentre M5200t, m8300t, m8320t, m8400t and m8500t systems. It matches the original FSP280-40EPA and HK380-16FP units and carries the 54Y8900, 54Y8851 and 54Y8859 part numbers. Buyers restoring or repairing those specific desktops receive a new unit rated for 100% working condition.

Proprietary 14-pin connector simplifies installation

The supply uses a 14-pin motherboard connector rather than the common 24-pin ATX layout, so it plugs straight into the ThinkCentre board without adapters or pin rearrangements. This exact fit removes the need to source separate cables or modify the chassis wiring harness. Systems outside the listed models cannot use this connector.

280 W limit restricts component upgrades

The 280 W rating caps the total power available to the CPU, graphics card, drives and peripherals. Adding a discrete GPU, extra storage or a higher-TDP processor will likely exceed the budget and cause instability. The unit is intended for like-for-like replacement in the original office configurations, not for expanded builds.
