... goes the powersupply in my gaming machine. 3 or 4 year old Corsair 850W. I've been hearing an occasional faint snap every once in a while but I could never figure out where it was coming from. But last night it was loud, and with 3 quick snaps in a row. I happened to have an ocean sound mp3 playing to help me sleep - it would hiccup with the snaps, easily ID'ing the source. Needless to say I shut it down. So out it comes. I'll have to cannibalize one from another machine since my biggest spare is only 600W and I don't think that'll cut it with my 6970HD.
