Genuine 180 W USFF replacement for OptiPlex 780

This genuine Dell power supply delivers 180 W maximum output in the USFF form factor. It is built specifically for the OptiPlex 780 ultra-small-form-factor chassis. The unit accepts 100-240 V input at 2.6 A across 50-60 Hz mains. It carries part numbers 0K350R, CN-0K350R, M178R and PS-3181-9DA.

Check chassis, connector layout and total power draw

Verify that the target system uses the USFF chassis and not a larger OptiPlex variant. Confirm the motherboard requires both a 4-pin P4 connector and an 8-pin 12 V ATX connector in this arrangement. Ensure the combined load of all installed components stays within the 180 W limit. The unit is not compatible with standard ATX or SFX mounting brackets.

No extra cables or software included

The supply ships as the bare unit shown in the product imagery. No additional power cables, mounting screws or adapter harnesses are bundled. No configuration utility, monitoring software or driver package accompanies the hardware. Installation relies entirely on the existing cabling and mounting points already present in the OptiPlex 780 USFF chassis.
