my friend will build a new pc and i want to know wat power supply should he get for core i5 4690 and 8gb 4x2 hyperx ram 1600mhz and gtx 760 oc edition 2gb windforce 3x will 550 be enoug or 600 would be better
headroom mean extra power for other components if they need it. A 550w would definatley run that make sure its from corsair(HX and AX are best), evga,seasonic,antec, or xfx all quality components and will last a long time.
