240W ATX Power Supply

This 240W ATX power supply delivers reliable power for compact or office-oriented desktop builds. It is suited for users replacing a failed unit in a compatible chassis or assembling a low-draw system that values efficiency and quiet operation.

Check part numbers and connector layout

Verify that your existing unit matches the listed reference numbers such as 54y8874, 54Y8897, 54Y8858, PCB020, FSP240-40SBV or PS-4241-02 before ordering. Ensure the 14-pin connector arrangement and physical dimensions suit your motherboard and case, as this unit is not intended for standard 24-pin ATX configurations.

Gold efficiency with semi-passive cooling

The 80 PLUS Gold rating and resonant LLC topology with DC-to-DC conversion keep waste heat low and reduce coil whine under load. A zero-RPM fan mode stops the fan entirely at low and medium loads, while Modern Standby support allows faster wake times and deeper sleep states for lower overall power draw.
