Based on what I am seeing it looks like the Z87X-OC is not good design and will end up failing before the Force will. Force has double the number of higher amperage rated true "OC" (per IR manufacturer guidlines) 3550 part. With the low rated higher spec choke the power has better digital distribution of cleaner power for pushing cpu. The Force is a much more cleaner power design and the "OC" with 3553M is has a much higher potential to put out low quality power.
The Z87X-OC is marketed as being budget no thrill get to the point over clocking mother board yet uses the same CPU power IR3553M part found in the much cheaper priced Z87 being used in the UD3H. I could have spent less money and got a UD4H with double the amount of IR3553 power(16) for CPU. This IR3553M part is recommended to be used in server motherboard not over clocked gaming mother boards.
Sorry but I coudn't find some of the reviews that lead me to believe the CPU VRM IR were IR3550. Vortez still shows some nice art work for the "OC" series that show IR3550.

I really thought the "OC" series featured this IR 3550 VRM for the CPU power.
No theory here. Just sharing what I have found. To me it seems Gigabyte was trying to offer a "OC" series MB with the Z87X-OC but cheapened out on parts to make the most money possible from hyping it up and marketing.
To the enthusiast it makes no sense to buy this MB because its obvious the main VRM power output desing was cheapened out. I know this now but when I ordered it I didn't realize the IR's being used were cheapened out.
I'm not seeing other results with high CPU over clocks for ambient temp cooling with the Z87X-OC either. My delidded bare die mounted 4770k requires 1.4v withis mother board to clear a pass of the pre configured tests of the new Linpack with AVX2 and temps are in the low to mid 90C so I really don't have much head room left.
In that VOrtez review link that I posted they had a much better quality 4770k that required much less voltage and wasn't delided and they could only get to 4.7GHZ.
If I had cleaner cooler power from VRM I think my CPU would do better.
Couldn't a bios update fix the power? It's all digital so I think there is room for BIOS improvement but right now things don't seem right for my over clocks on ambient temps and I am not seeing many people results with ambient temp cooling and most people seem more interested in RAM speed. I am more interested in MAX CPU over clocks.
