We measured the power consumption with the system resting at the Windows 7 desktop, representing idle values.
The power consumption of our entire test system (at the wall) is measured while loading only the CPU using Prime95′s in-place large FFTs setting. The rest of the system’s components were operating in their idle states, hence the increased power consumption values (in comparison to the idle figures) are largely related to the load on the CPU and motherboard power delivery components.
With a low number of add-on components or efficiency-hampering PCB space, Gigabyte's X99M-Gaming 5 is able to show positive idle power consumption numbers, especially when overclocked.
The load power usage levels are equally positive, showing that Gigabyte's decision to opt for the quality of power delivery phases over their quantity, was a smart one.
ASRock Fatal1ty X99M Killer seems like the Best bet with a 4x m.2
I have been having that odd GPU load crashing issue, and I was beginning to think that I was going crazy. System is totally stable otherwise, Aida64 for 10+ hours with no issues, browse the web, watch movies, etc no problems. Game for more than a couple of minutes and crash, every time.
At first I thought it was my XFX R9 270X, so I grabbed my other one (I pulled these out of a crossfire setup on my other system) and same issues occurred. I was just starting think about returning motherboard when I came across this post. I am going to try this fix when I get home and see if it resolves the issue for me.
