Linking to Newegg is hardly research
On the Silverstone site the previous model ST45SF lists the 670 and 680 explicitly as compatible GPUs. Anandtech did an overclock test of all the release-day 670s with an overclocked i7-3960X and saw maximum draw of under 350W for the whole system (remember i5-3570K takes is much less consumption than the i7-X series). http://www.anandtech.com/show/5818/nvidia-geforce-gtx-670-review-feat-evga/18Moreover, since the GTX670 only has two 6-pin PCIe sockets, it won't draw more than 225W (75W from the motherboard and 2x75 PCIe). That's less than 19 amps. It leaves 18 amps for the rest of the system.
