Review on 🔌 LXun 290W Power Supply Dell Optiplex 3020 7020 9020/ Precision T1700/ PowerEdge T20 (Compatible PNs: RVTHD KPRG9 HYV3H H290AM-00 D290A001L L290AM-00 PS-3291-1DF H290EM-00) by Kenkoy Braggs

My PS fan drove me crazy. So I figured I'd just swap out the whole PS. Arrived on time, took out the old one, installed a replacement. stillness and peace. Running all night, restarted PC to update and it showed up, then disconnected at that time. I rummaged through my old junk drawer and found a new fan. Exchanged in my old PS, reinstalled and everything is quiet in the store. Sorry guys either parts or labor fail you. My guess is that old caps don't pull wires etc. Returned for credit thanks to Amazon.
