DELL desktop power supply replacement

This 240 W ATX unit is built to replace the original power supply in DELL OptiPlex 7040MT, 3650, 3040 and 3046 tower chassis. It matches the L240EM-00, L240AM-00 and B240NM-00 part numbers so the connectors and mounting points line up without adapters. The unit is new and ready for installation in compatible business desktops.

240 W capacity for standard office builds

The 240 W rating covers typical office configurations with integrated graphics, a single hard drive or SSD and standard memory. Systems upgraded with a discrete graphics card, multiple drives or high-wattage processors will exceed the available headroom and require a higher-output supply. Builders planning such expansions should verify total power draw before ordering.
