Intel Motherboards : Z170 Extreme7+ Sleep Issue

I've actually RMA'd the power supply right after I got it, due to coil wine when it was under load. It's a Corsair CX750 (which should be plenty). I've disassembled the board all the way down to the core components ( CPU / RAM / SSD with Fresh Copy of Windows 10 / Onboard Graphics ). It won't come back from boot following that. After we trouble shot everything, I RMA'd the board to ASRock and they sent me another one... same test conditions, same results. 

The only thing I haven't tried doing is hooking another PSU into the board and trying to do it from that. I don't exactly have another brand of PSU to test it with at the moment so ... yeah. I don't think it's that though. Oh and it could be the CPU... but... if the CPU doesn't have any issues on boot, then it shouldn't have any issues on sleep recovery. 

I think I mentioned it, but the last thing they did was send me a BIOS chip replacement. I did wipe that over and do an internet update on it and then switched to it... it's working fine off the chip now... but sleep is still in-op

I think the only options here are to do a RAM swap (brand new ram from GSkill or someone) or just start looking for another board (which would be cheaper than replacing 32GB of DDR4 3200MHz RAM). 

The thing that really rubs me the wrong way is that ASRock acts like it's something I'm doing wrong or that I'm lying about the situation. I don't know that I'll ever buy another board from them after this experience though.
