The 6970 was probably the only thing under full load. That is, the CPU was probably idling. That's usually how it's done during such tests of video cards.
With one 6970 under full load in their system, their PSU pulled 312W from the wall outlet. Their CPU was idling, so I have to add about 125 for your FX-6300 overclocked to 4.4 GHz (this is approximate, it could be more). So, adding 125W to 312W makes the PSU pulling 437W from the wall outlet. This means that if the PSU is 85% efficient while pulling 437W from the wall, then the computer is pulling 371W from the PSU. With your PSU's +12V capacity of only 312W, this will likely cause problems for you while gaming. Take the CPU down to stock, and you might have a chance.
