This 240W power supply matches part numbers 54Y8819 54Y8846 PC9053 PS-5241-02 HK340-71FP. It fits the listed desktop chassis and restores factory power delivery. It is not for systems that need a higher wattage rating or a different mechanical layout.

Capacity and headroom

Rated at 240W maximum output the unit handles the original platform load with headroom for typical peripherals. It runs out when the combined draw exceeds the rated limit or when a configuration demands more power than the original design allowed.

Thermals noise and power draw

The supply accepts 100-127V at 8A or 200-240V at 4A across 50-60Hz. In normal operation the internal fan moves air through the 17.5 x 8.5 x 6.5CM housing keeping temperatures stable and acoustic output low.

Questions about this item

Will this 240W unit fit and power my M70E or M91P desktop that originally used part 54Y8819?

Yes, it matches part numbers 54Y8819 and 54Y8846 and is listed for M70E, M75E, M81 and M91P desktops.

How can I confirm the PS-5241-02 is delivering stable power after installation?

The system should boot normally, show no power-loss events under load, and the fan should spin quietly at 100-127V or 200-240V input.

Does the HK340-71FP come with the AC cable and mounting screws, or must I source them separately?

The unit includes the power supply only; the IEC power cord and any chassis screws are not included and must be supplied separately.
