What This 240 W ATX Unit Powers

This 240-watt ATX power supply fits Lenovo ThinkCentre M57E, M75E, M70E, M77, M90P and M91P desktops. It carries 80 PLUS Gold certification and a resonant LLC topology with DC-to-DC conversion for clean, efficient power delivery. Modern Standby support gives extremely fast wake-from-sleep times and better low-load efficiency. The Zero RPM fan mode stops the fan at low and medium loads for near-silent operation.

Who This Fits and Who It Does Not

System integrators maintaining the listed ThinkCentre models can use this unit as a direct replacement. Builders assembling custom ATX chassis or upgrading power-hungry graphics cards should look elsewhere because the 240 W limit and proprietary fit prevent such use. Offices needing higher continuous output for workstation components will also need a different solution.

The Deciding Specification

The 240 W rated output is the single figure that determines compatibility. If the target desktop draws more power under load, this supply will not sustain stable operation. Match the wattage to the system's maximum demand before purchasing.

Questions about this item

Which of the part numbers — 54Y8846, 54Y8826, 54Y8819, 54Y8887, 89Y8586 or 54Y8862 — matches my Lenovo desktop?

Match the part number printed on your existing unit; each code corresponds to a specific Lenovo M-series chassis such as the M57E, M75E, M70E, M77, M90P or M91P.

What does the 240 W rating mean for daily use in one of those machines?

It delivers up to 240 W of continuous power, sufficient for the original CPU, integrated graphics and typical office peripherals in the supported Lenovo systems.

How does the ATX form factor and 80 PLUS Gold rating affect installation and running costs?

The unit follows the standard ATX layout so it mounts directly in the listed Lenovo cases, and Gold certification means higher efficiency across typical loads, reducing waste heat and electricity use.
