Oh yes. More than enough.

BarbaricSoul · Dec 5, 2015

it should be fine

GreiverBlade · Dec 5, 2015

yep more than enough (it would be enough in my case if i did SLI, check my sys specs)

If you're overclocking and using a custom bios on both cards, with an overclock on your CPU as well, it could start cutting it pretty tight. The 970s are very capable of pulling 300 watts each, of system power when overclocked with a custom bios. With a stock bios you're fine though.

yes, it is more than enough. unless you do overclocking on both ends I:e CPU and GPUs. try to stay within constraints and you are good to go.
