Supersuperuncle server power supply 250W for Dell 390 790 990

SKU CH-V74E-XHQ5T

250W replacement power supply compatible with Dell 390, 790 and 990 systems

  • Compatible with Dell 390 790 990 systems
  • Replaces Dell D250AD-00 L250PS-00 F250AD-00 units
  • 250 watt output for medium power needs
  • New condition ensures reliable server operation

Replacement PSU for Dell OptiPlex towers

This 250 watt server power supply is built as a direct replacement for the Dell OptiPlex 390, 790 and 990 medium chassis. It matches the original D250AD-00, L250PS-00 and F250AD-00 part numbers so the unit fits the proprietary mounting points and connector layout without modification. The supply ships new and ready for installation in compatible office or home-lab systems.

Not for small-form-factor or high-power builds

The 250 watt rating and medium-tower form factor mean this unit will not fit small-form-factor OptiPlex cases nor deliver enough power for configurations with discrete graphics cards or multiple drive arrays. Buyers needing a compact PSU or higher output should look for a model specified for those chassis and load requirements.

Questions about this item

What does the 250 W rating mean once the unit is installed in a Dell 390, 790 or 990?

It supplies up to 250 W of continuous power to the motherboard, drives and expansion cards in those chassis, matching the original D250AD-00, L250PS-00 and F250AD-00 specifications.

Which power interface does this supply use and what does it limit in practice?

It uses the proprietary Dell medium-tower connector keyed for the 390, 790 and 990, so it only fits those models and cannot be adapted to standard ATX boards.
