Good replies so far I was wondering if I didnt jump to too many conclusions from just the one test so far I have been browsing Nvidia for a untility for power supply testing. I have checked the bios before for voltages but havent seen it yet, I will look again tho. I tried the Occt stresstest .. I must admit I got a bit Squemish when I saw one of my temps on my gpu go up to 71 I am guessing that is celsius so I stoped it short at 7 minutes .. one card is running ten degree's hotter .. but thats probaly not a real issue .. maybe I didnt get enough dust out of the fans.
I can run it more for the sake of a better picture but even in that short time its showing a trend of under voltage .. if there is anything else I can try .. or run it longer let me know
