There's a difference between that 550 and the 650. The 550 has probably about 200w overhead due to the components used. Try to remember that although the TX650 is really good, it's still only a step ahead of their budget line. If he had an Intel CPU I'd say it would be no big deal, but the 8350 pulls almost double that of a Haswell or IB and the 760s aren't factory clocked. They take over half the rated wattage by themselves.
Edit: Oh yea Sean, the 690 takes about 40w less than 2 reference 760s. Although with only a mild overclock I'd be willing to bet the wattage on his cards would be closer to 375/400 compared to your 300.
