Your system draws like 500W from the wall max under full load, even after a hefty overclock on the both the GPU and CPU. Also, Reason why hes recommending the MSI card over the EVGA one is cause, your spending alot more money for the exact same card, just a different cooler. So if that cooler is really worth the 80 dollar difference to you then go get it. Other than that, both use reference PCBs.
