i just downloaded Overdrive to check few things , and i managed to see CPU and GPU temperatures .. but when i opet Voltage section i can't understand a thing .. I might be having Power supply problems since i have old beast GPU (radeon HD 5970) and she takes alot of voltage so could someone tell me is it ok ? and are these informations from OverDrive enough to determin power supply status ?
