Power Draw Tests
Looking at the power draw side of things, we can see that the P9X79 Deluxe is drawing similar power numbers to the Rampage IV Extreme with both boards sitting higher than the MSI one. Overclocked we see those numbers blow out even more with an extra 100 Watt of power draw at load over stock.
On the temperature side of things we can see that our stock numbers line up fairly close with each other, with the MSI one coming in a little cooler. Overclocked, though, we do of course see quite a jump in the heat.
