I'm currently running Cooler Master Extreme Power RS500-PCAR-A3 ---I have heard advice about how weak and poor efficiency this PSU is and that i should get one with 'true power' instead. Recently i upgraded my gfx to HD 6870 which requires 2 X 6 Pins, and since i have only 1, i used the 4Pin+4Pin to 6Pin adapter and it appears to be working pretty okay. But i worry that my PSU would cause problems when i OC my hd 6870. Will a lousy PSU lower the stable speed i can get? I have 1 X 7200 HDD, 1 X dvd drive and 1 ext usb wireless adaptor. On i7 860 2X2gb ram. Would this setup be screwed over by the bad PSU? Thanks
