Out of the box, the power draw on the MSI Z87I is fantastic, with an idle number that sits lower than all other boards we've tested. Considering the size of the board, we would expect the power draw to be lower, as there's just simply less to it.
When it comes to load, though, you can see that we're sitting in line with the other boards. Overclocking of course moves both numbers up, but with 85 watts at idle and 318 watts at load, these aren't exactly worrying numbers.
Checking out the CPU temperature, you can see we're sitting low and in line with the GIGABTYE Z87X-OC. Overclocked we see the load number jump up by a decent amount to 85c.
It's not quite as brutal as the 100c we've seen from some of our other boards recently, due to the fact that the overclock is both not as high and we're not pumping as much voltage through the CPU.
