I will oc my i5 atleast 4.4,4.5 ghz
That CPU overclock would take around 26 Watts more than when operating at stock clock setting.
Overclocking the ASUS Strix GTX 970 would increase the graphics card's maximum power consumption by 33 Watts.
The Corsair VS650 is theoretically more than sufficient to handle the overclocking.
