180 W SFF Power Supply for OptiPlex

This Dell H180AS-00 unit delivers 180 W of power in a small form factor design. It is built as a direct replacement for the original supply in compatible OptiPlex desktops. The unit accepts a wide 100-240 V input range at 50-60 Hz. It suits owners of listed OptiPlex models needing a new or spare power source.

Suits OptiPlex 3040 5040 7040 3650 3656 SFF owners

This supply fits the OptiPlex 3040, 5040, 7040, 3650 and 3656 small form factor chassis. It is not for standard tower or micro tower cases that require a larger PSU footprint. Builders wanting higher wattage for discrete graphics upgrades should look at something else. It also does not fit non-Dell proprietary chassis designs.

Verify OptiPlex SFF model and part number match

Confirm your system is one of the OptiPlex SFF models listed in the compatibility data. Check that the existing unit carries part numbers 4R1KT or 04R1KT for an exact match. Ensure the chassis is the small form factor variant and not a larger tower version. The 180 W maximum output must meet the power needs of your installed components.
