Dell OptiPlex 290W Power Supply – PS-3291-1DA / WHN49 – Fits 3020, 7020, 9020 (SMT) & Precision T1700

Got a Dell OptiPlex or Precision tower that needs juice?

This is a 290-watt power module pulled from a brand new system.

It's a genuine Dell part, model PS-3291-1DA (also known as WHN49, HYV3H, or L290EM-01).

It fits the Mini-Tower versions of the OptiPlex 3020, 7020, 9020, and the Precision T1700.

A heads-up though: since it was installed in a system, it might have some minor scratches from handling, even though it's functionally new.

Just want to be upfront about that.

Works with standard 110V/120V.
