Running LinX right now... 5 passes in out of 10 at "All" for RAM and the CPU is running in the mid 50's and the PSU exhaust feels fine... I've not had storms come through and I've taken very good care of my stuff. The only thing that might possibly have ****ed it up is when I do a leak test and do the PSU paperclip trick to turn it on and off. I've only done that 3 times to this PSU. LinX passes take forever at high problem sizes ugh I wanna play WoW lol... Thanks for helping with this though man, I appreciate it!It's possible, but I doubt it. Not unless you've gone through some bad storms or your PSU was abused in that way. Mine is an older model too and I damn near blew it up trying to pull a retarded amount of power through it, but it still chugs. If you feel you should replace it, go ahead, to have a new unit before the warranty is up.
