Power and Temp

We tested the power utilization at the wall of the entire system. For full load power and temperature testing we used real gaming. The power supply used in testing is a Enermax MaxRevo 1350W. Total system wattage at idle without video card is 86W.

The default full load system wattage on the MSI R9 390X GAMING 8G is 494W. When using the overclock which changes voltage the system wattage rose to 540W. This is quite high, we can imagine that with two of these cards in CrossFire overclocked you'd need at least a high quality 1000W PSU, and probably you would be better off with a larger wattage PSU to sustain these.

The GeForce GTX 980 when overclocked rose from 312W to 366W. Given the fact that the overclocked GeForce GTX 980 is faster than the MSI R9 390X GAMING 8G when overclocked, and consumes a lot less power, the overclocked GTX 980 hands down is the more efficient video card. It is able to provide a higher overclock, faster performance, with lower wattage. Talk about performance per watt! The GeForce GTX 980 walks all over AMD Radeon R9 390X in terms of PPW.
