  • Worked like a charm
I bought a optiplex 790 from an auction and the power supply was dead when I plugged it in. I pulled the power supply and ordered one of these worked like a charm. If the light is blinking orange your power supply is probably toast.

  • Easy to install
Ordered it; Arrived next day; Easy to install. I had ordered a generic power supply prior to this one, however, it didn't fit properly so I ordered this one. This power supply slid right in without a hitch and 15 minutes later I was up and running again.
