Compatible 290W replacement for OptiPlex MT

This 290W ATX power supply is built as a direct replacement for the original units shipped in DELL OptiPlex 3020, 7020 and 9020 mini-tower desktops. It matches the factory pin-out and mounting points so the system powers on without adapter cables or case modifications. The unit is new and ready for immediate installation.

Replaces failed or degraded OEM units

It takes the place of L290EM-00, AC290AM-00, H290AM-00, HU290EM-00 and L290AM-00 power supplies when the original fails, becomes noisy or can no longer hold stable voltages under load. The upgrade is worth it when the desktop shuts down unexpectedly, shows POST power errors or the fan runs at maximum speed continuously. Builders adding high-wattage graphics cards or extra drive arrays should look for a higher-capacity supply instead.

Questions about this item

Does this 290W unit fit the standard ATX cut-out in a DELL OptiPlex 3020 MT chassis?

Yes, it is an ATX type supply built to match the L290EM-00, AC290AM-00, H290AM-00, HU290EM-00 and L290AM-00 form factor used in the 3020, 7020 and 9020 MT models.

Which power cables must be connected during installation, and which one is most often missed?

Connect the 24-pin main motherboard plug and the 4-pin CPU power plug; the 4-pin CPU connector is the one installers most frequently forget to seat fully.
