Hi, I have a EVGA Supernova P2 750w and was wondering if it is ok to have a power draw of 650w out of the PUS. I have read that you should have at least 20% from max watts the PSU can give. So is it ok to have a 750w power supply and use 650w of it or could problems arise?
If you're not overclocking, you should be good to go. Though just for the sake of reference, how old is the PSU? Older units will have capacitor and internal componentry degradation which will reduce the effective power output from the PSU.
