So I was wondering if a rm series 750w psu would support 2 r9 290's? I have the sapphire toxic already OC card and was wondering if I got a 2nd would this 750w be able to handle it? The max a r9 290 gets to is like 220w, isnt it? so surely if i got 2 that leaves about 200w for cpu and other components.
I wont ever use stress testing on the powersupply or benchmarking.
Could this be done?

I have:
intel i5 4670k-Stock fan and not overclocked
2x4gb ram
z87 hd3 mobo
2 x 1tb 7200rpm HDD
6 case fans
RM Series fully modular 750w psu
Nzxt hue
r9 290-factory overclocked
Is that too much? I got a fair few fans for good air flow, nzxt hue for decoration and the rest is pretty basic, could the 750 handle it?

hmm,do you think it is a safe "tight fit" though,would it realistically exceed 750w? 2x275=550w
750-550=200w
cpu usage-?? cant find this info
2 hdd = 25w max
6 fans= 10w max
mobo = ??
ram= 5w max
this leaves about 160w for cpu and mobo. Is that good?
