Power Draw Tests

Power draw numbers on the new platform are excellent. Idle numbers at stock and overclocked are lower than any of our other setups. The same goes for load numbers at stock speed.

It's only when we overclock that we see it jump up, but mid 300 watt is an extremely impressive number considering the performance on offer from these new Haswell parts.

Core Temperature

Out of the box the i7 4770K runs a bit warmer than the i7 3770K when it comes to load numbers. Looking above you can see those idle numbers are up a bit more, sitting just a little lower than the i7 3970X Extreme Edition.

Overclocking, though, you can see jumps up into the 90c range, which was quite common with the 3770K as well.

We had hoped that it would've been a little lower. Saying that, performance was rock solid at all times and we never experienced any issues.
