250W replacement PSU for slim Dell desktops

This 250-watt server power supply replaces the original unit in compatible Dell Optiplex, Inspiron, Vostro and Studio slim systems. It delivers up to 250 watts of DC output from a 100-240 volt AC input rated at 4.4 amps. The unit is new and matches the D250AD-00 and H250AD-00 part numbers.

Verify your current part number and connector layout

Before ordering, confirm the existing power supply carries one of the listed compatible part or model numbers such as CYY97, 7GC81, L250NS-00 or DPS-250AB-67 A. Check that your motherboard uses a 24-pin ATX main connector and a 4-pin ATX auxiliary connector. Ensure the chassis can accept the same physical form factor as the original slim desktop unit.

Fits slim DT builds with SATA drives

The supply provides one 24-pin ATX connector, one 4-pin ATX connector and three SATA power connectors for drives. This covers the main board, CPU auxiliary power and up to three SATA devices such as hard drives or SSDs. Builds needing PCIe power connectors, additional SATA ports or higher wattage for discrete graphics cannot use this unit.

Questions about this item

Does the box include only the power supply unit or are mounting screws and cables also supplied?

The unit is supplied as the power supply only; mounting screws and any extra cables are not included and must be sourced separately.

My Dell OptiPlex 790 lists part numbers D250AD-00 and H250AD-00; which one should I select?

Both part numbers refer to the same 250 W unit, so either D250AD-00 or H250AD-00 will fit the OptiPlex 790.

What does the 250 W rating mean when the supply is installed in a Slim OptiPlex chassis?

The 250 W figure is the maximum continuous DC output the supply can deliver across its 24-pin ATX, 4-pin ATX and three SATA connectors.
