Is your Dell desktop acting up or not turning on?

Might be the power supply.
This 250W replacement is compatible with a ton of Dell OptiPlex, Vostro, and Studio models.
We're talking OptiPlex 390, 790, 990, 3010, and the SFF models like 537s, 540s, 545s, 546s, 560s.
Also fits Vostro 200s, 220s, 230s, 260s, 400s and Studio 540s, 537s, 560s.
Important note: this is for the small form factor (SFF) systems, NOT the mini tower (MT) or ultra small form factor (USFF) ones.

It replaces part numbers like D250AD-00, PS-5251-08D, L250NS-00, and a bunch of others listed.

If your old PSU failed or you're upgrading a build, this is a direct swap.

Just make sure to match your model and part number.

Installation is pretty standard if you're comfortable working inside a PC.
Get your Dell desktop back up and running with a reliable power supply replacement.
