DELL Ncyvn 250 W Switch Module for Optiplex 790 990

250 W power supply for Optiplex 790 990

This 250 watt unit is a direct replacement power supply built for Dell Optiplex 790 and 990 desktop towers. It delivers the rated wattage the original chassis and motherboard expect. Buyers who need a higher output for discrete graphics upgrades cannot use this module.

Fits Optiplex 790 and 990 DT chassis

The supply mounts inside the original desktop case and connects to the existing motherboard power headers. It frees the builder from sourcing proprietary pin-out adapters or modifying the case. No additional cables or brackets are required beyond what the Optiplex 790 or 990 already provides.
