240W PSU for Dell Optiplex SFF

This 240-watt ATX power supply is built as a direct replacement for Dell Optiplex 3040, 5040, 7040, 3650 and 3656 small-form-factor desktops. It ships new and is tested before dispatch to match the original L240Am-00 specification.

Check part number and connector layout

Verify that your current unit carries one of the listed part numbers such as Thrjk, 4Gtn5, D7Gx8 or Hgrmh and that the motherboard uses the combined 8-pin and 4-pin power connector arrangement. The supply is intended only for the SFF chassis models named above.

Unit only with tested reliability

No cables, mounting brackets or software are bundled beyond the fixed leads attached to the PSU itself. The practical difference is that every unit has already passed a functional test, reducing the chance of a dead-on-arrival replacement.
