They can be had for $10 or so. Check the voltages on each rail with a load on them. If they deviate much from their intended voltages (12v for Yellow, 5v for Red, 3.3v for Orange), then that may indicate a problem. m 0 l welliam September 1, 2010 12:24:13 AM thanks I had one already and I did that the voltage are normal, but how I can put my rig on load ? I have now i7 860, one hard drive, 8800 card so no heavy load on the psu but later I will add two other drives + gtx 460 m 0 l Can't find your answer ? Ask !
