Well I had an Antec Trupower II 550w SLI power supply die on me last week when something blew in side of it and replaced with an Ultra 600w SLI PS. About a year ago, I started having a problem where none of my BIOS settings were saving if the PS was disconnected or there was a black out. I replaced the battery and it didn't help. Thought it would be something I had to live with. Well put in the new PS, and 2 days latter we lost power for an hour or so. When I turned on the PC, all of the settings were saved and I didn't have to reset everything in the BIOS. Two problems solved with one fix....Just curious, any thoughts what might have been happening?
