Compatible SFF servers
This 180W power supply is built for Dell OptiPlex 3040, 5040 and 7040 small form factor systems as well as the 3650 and 3656 SFF models. It replaces part numbers 5XV5K, RWMNY, 9XD51, L180AS-00, PS-3181-1DF and H180ES-00 in those chassis.
Who this suits and who it does not
It fits owners of the listed SFF desktops or servers who need a direct 180W replacement with an 8-pin plus 4-pin CPU connector. Builders working with larger towers, higher-wattage platforms or systems that require modular cabling or PCIe power connectors should look elsewhere.
What to verify before ordering
Confirm your chassis is one of the compatible SFF models and that the existing unit uses the same 8-pin plus 4-pin CPU power arrangement. Check that the 100-264V input range matches your mains supply and that the non-modular cable layout will fit your case routing.

Questions about this item
Does this PSU fit a standard ATX motherboard 24-pin connector or does it use a proprietary Dell pinout?
The L180AS-00 is built for Dell 3040, 5040 and 7040 SFF chassis and uses the proprietary 8-pin plus 4-pin motherboard connector, not a standard 24-pin ATX plug.
Can I reuse the 6-pin PCIe cable from my old GPU with this unit?
This 180 W supply provides zero 12 V graphics pins, so there is no PCIe cable to connect; a discrete card requiring external power will not run.
How do I confirm the PSU is delivering power after installation?
With the 4-pin CPU and 8-pin main connectors seated, the system should POST and the front-panel power LED will show solid amber or white depending on the model.
