"Whether it was running MemTest86 with a 2GB kit of memory at DDR540 for 297 hours straight, or dual priming an X2 3800+ at 2.9GHz and an Asetek water kit for over 48 hours, or finding the maximum 2.5-3-3-5 frequency of a trick TCC5 kit and passing 310HTT 1:1 on chilled water, none of the systems had a failure, reboot, or random possible power related issue. Voltage always remained within specification but did drop below 12v on occasion under heavy loads with a couple of the units but for the most part they all seemed to hold their own."
