Although i "do not" need a new psu looking at the recommended power for my parts and with the use of cooler masters psu calculator i wonder if it would be good to upgrade. I have a i7 4790k with no oc yet and 2 windforce r9 290's.i have a 750 watt power supply what is enough but my worry is the bronze efficacy is less stable of a current and if a spike happens at a low poing of the current something could go wrong. im thinking of getting around a 800 watt gold psu i dont know what type yet just because i have a bit of over head and expandablity for hopefully watercooling this spring when im back working (high school student with no expenses so i work to afford computer parts haha!) whats your thoughts on a new psu, is it needed sooner or later.
