I got a thermaltake 420w true power. Athlon 5000+ overclocked to 3ghz, 2gb ram, 3 hard disks, dvdrw, floppy and 8800GT graphics card. the PSU is almost 2 years old (I had it in an older, weaker system). I've been running this config for about 2 months. today as I was playing Jericho after an hour so the pc turned off instantly (no blue screen or anything, just off, like electricity was lost, but it wasnt, as the mouse still had light and the room still had electricity). I'm guessing this is a sign that the PSU is going to fail? I rebooted 2 hours ago and it's ok , but havent played any games yet to stress it. the thing is , I did log the voltages using speedfan and they were normal at the time the pc went off.
