So, I'm planning this build this summer which will invlove dual 7870s, an intel 4670k and maybe a few ssds, hard drives, fans and other junk. I put everything into cooler master's psu calculator, even on their advanced settings and the calculator said I would need a minimum of a 430 watt power supply (or something around that). Is that really feasible? It seems like that would be really low.
I was considering getting antec's 550w platinum earthwatts psu. I know I could probably use a couple suggestions, but I thought, eh what the heck, might as well get the most efficient thing I can.
Anyway, please leave suggestions, and if there are any, let me know of other ways I can calculate the wattage I'll need, thanks!
