Hmm...... I avoid Coolermaster PSUs now as I had one go bang with a puff of black smoke after 24 hours use, that was a 750W one. RMA'd it and got it replaced with a Corsair. According to my supplier "someone" had omitted to fasten one of the chips to a heatsink and it exploded!

I had problems with two XFX PSUs which had failed 5V standby circuits causing the PC to fail to boot. I'm now quite happy with the EVGA PSU I bought as a replacement. They also offer a 10 year PSU warranty.
