My Optiplex 790 Mini Tower died suddenly after losing power for about a week. It just wouldn't turn on and I couldn't turn the light green or amber so I figured it was the power supply. Took me about 5 minutes to uninstall the old one and maybe 3 minutes to install the new one. Now it shines like new again; Who knows, maybe I can live with this thing for another 10 years! However, the PSU was brand new in new packaging and is a genuine Dell OEM product. Highly recommended.
