Genuine 200 W Dell power module for OptiPlex USFF

This Dell PS-3201-9DA power supply delivers up to 200 W for OptiPlex 780, 790 and 990 ultra-small-form-factor systems. It accepts 100-240 V input at 50-60 Hz and draws a maximum of 2.9 A. The unit is supplied new and weighs 3.1 kg.

Continuous 200 W output with dual rail connectors

The supply is rated for a sustained 200 W maximum rather than a short peak. It provides one 8-pin connector and one 4-pin ATX connector to feed the motherboard and peripheral rails. Input frequency tolerance spans 50 Hz to 60 Hz for stable operation across regions.

Verify USFF chassis and connector match before

This module fits only the ultra-small-form-factor variants of the listed OptiPlex models; tower or small-form-factor versions use different housings. Confirm that your system requires the 8-pin plus 4-pin ATX combination and that the original part number matches C0G5T or 1VCY4.

Questions about this item

How much power does the 200W unit draw from the wall when the OptiPlex runs continuously?

The supply accepts 100-240V at up to 2.9A, so maximum input power stays within the rated 200W output envelope during all-day operation.

Which motherboard connectors must already be present on the OptiPlex 780, 790 or 990 USFF for this PS-3201-9DA to plug in?

The unit provides one 8-pin and one 4-pin ATX connector, matching the factory headers on those USFF chassis.

Will the PS-3201-9DA fit the same mounting points as the original C0G5T or 1VCY4 supply in a kept OptiPlex 790 USFF?

Yes, it shares the USFF form factor and the listed compatible part numbers, so it aligns with the existing screw holes and chassis guides.
