hi everyone
my question is about the +12V rail, i know that high-end Graphic cards draw their power from this rail. then i recently knew that haswell CPUs also get their power from this rail (through the Mobo VRM). am i right until now?
i have an "XFX PRO1050W Black Edition Full Modular 80PLUS Gold" PSU with 87A on its only one +12V rail. i bought a EVGA GTX 780 SC ACX (the recommended amperage on the +12V rail is 42A".
so i assumed that i will be able to get another 780 in the future as SLi (42*2=84), then i realized that my i5-4670k will draw about 17A when OCed on load. (169W / 12V / 0.8 efficiency => 17A)
so in total i will need 42A+42A+17A = 101A on the +12V rail?
can anyone explain to me? am i right?
