No, your power consumption with two GTX 970s in this build would never exceed 450 while gaming (and with one GTX 970, it would never exceed 300W). Seriously, these things just
sip power, and the i7-6700 just sips power too, never pulling more than ~65W.
So, you could even power this with a good quality-made 550W PSU if you wanted to.
Here:

With two GTX 970s in SLI and under full load, their PSU pulled 439W from the wall outlet. The i7-6700 can pull up to 65W under full load, so here's how it breaks down: if we assume that Guru3D's PSU was 90% efficient while pulling 439W from the wall, then that means their computer was pulling about 395W from the PSU. Add 65W to that, and you have an absolute maximum of about 460W. While gaming, the power consumption will never exceed 400-425W.
With one GTX 970 under full load in their system, their PSU pulled 274W. Assuming 90% efficiency, their PSU pulled 247W from the PSU. Add 65W to that, and we have 312W. While gaming, the power consumption would be lower, never exceeding 275-300W.
So yeah, that's why I have two 550W PSUs in that list.
Anyway, again, the XFX XTR Series is a fully modular version of the SeaSonic G Series.
