That rig will stay under 400W under full load. Hell, I have a 500W PSU and I run an i5 4690 and a GTX 970. PSU recommendations have really blown out of proportions nowadays, and while I'm absolutely for having a little extra juice for the machine, having a 500W is just that. He could be fine with a 450W or even a 400W, but that would be really pushing it.
Here's a little something something: http://outervision.com/power-supply-calculator It didn't have the 6100 yet but the 4360 should represent it just fine. Got 335W full load.
