Coolermaster 600W psu hey guys. Can a stressed PSU cause bad overclocking and bsod`s? My Coolermaster 600Watt Igreen psu seems to be undervolting,but its only about 5-6 months old. The 12v rail is always at 11.89 v at idle and drops to 11.84 under load. The 5v is also at 4.89 and under load down to 4.82,and the 5v+ the same. Is this cause for concern. My overclock that was rock solid a few months ago has suddenly become increasing unstable. I have even tried manually setting the voltages in bios,but no joy. I had my cpu at 3.2 gigs before with a 355FSB,now I cant do much more than 300FSB. Is something else failing perhaps that Im not aware of. Specs as follows: Asus P5N32E-sli C2D E6600 at 3gigs 2x Kingston ddr800 Hyper X(2gigs) Asus GTS 8800 320M 2x Seagate 250gigs Sata2 Zalman 9700led cpu cooler 2x120mm Zalman System fans 1x240mm Sidefan Creative Audigy 4 s/card Logitech Momo wheel MS kb and mouse Logitech Z5300 speakers Liteon sata dvd writer Im using Everest 4.20 to test the loads on psu rails. Any suggestions welcome.

I am probably using the term incorrectly but, when the voltages are dropping below what they are set to or "supposed" to be. Most of the time the term is used in ref to a mobo's ability to maintain the set voltage in the bios. Simple version. In your case, the PSU is being asked to handle more than it really can. The voltages can not be maintained. Using a volt meter will tell you this for sure. If at no load your 12V rail is say 12.4 volts, but once you load it with all your components and your OC then the 12v rail only reads 11.8v, there is a problem. +/- 5% is what is required by standard, that does not mean that your components will like even a 3% drop.
