Product overview
D250AD-00 is a Dell 250W desktop power Supply (24-pin ATX, for OptiPlex 390/790/990/3010, inspiron/vostro/studio slim desktops). Power supplies must match the chassis, the wattage the configuration actually draws and, in a redundant pair, each other. This unit is 250W. Send us the server model and current PSU part number and we will confirm the pairing.
Send the part number of the supply already fitted and we will match it rather than merely match the wattage.

What you get ordering this from us
Ordered by part number
D250AD-00 is what is quoted and D250AD-00 is what ships; where an alternate code is genuinely the same part we name it rather than swap it silently.
Draw calculated, not assumed
We work out what the configuration actually pulls before recommending a wattage.
Matched to the installed unit
Send the part number already in the chassis and we supply its pair, including the efficiency grade that stops the mismatch alert.
Questions buyers ask about this part
Is D250AD-00 genuine and is the warranty intact?
Yes. It ships new in Dell packaging, which is what keeps the warranty and the firmware entitlement valid. Anything we cannot supply that way we tell you about before you order.
Will D250AD-00 work in my server?
Send the server model and the part number of the supply already fitted. In a redundant pair both units have to match on wattage and efficiency grade, or the chassis alerts on every boot.
Do you accept purchase orders and quote at volume?
Yes. Purchase orders are accepted from qualified organisations, net terms are available on approval, and tiered pricing applies at quantity. Tell us how many you need.

Specifying a system, not just the part?
An accelerated node draws far more than a general-purpose server, so power is sized with the build rather than assumed from the chassis.
