pc shuts off coming out of sleep mode

[piper42]

I have been building gaming computers for myself mostly for about ten years. I just finished a new build and have tested it and have had no issues. I bought a 550w evga g2 and thought because I wanted a little more headroom I replaced it with a 650w g2 and will keep the 550w for backup. Its fully modular so I didn't have to change any of the cables. Since then when wake my computer from sleep mode it acts like its going to come on then shuts off. I cant figure it out. Anyone have a similar issue in the past that could help with this issue?
6600k i5
msi gaming m5
2x evga 960 4g sli
16g gskill ripjaws
950 Samsung m.2 240
850 Samsung evo 500
evga 650w g2 supernova
corsair h60
nzxt s340
Also on a side note I have my cpu overclocked to 4.5 at 1.125 completely stable. Is this the norm for skylake or did I just get a good one?

Problems with sleep are usually power or motherboard related, so first thing to do is disable any overclocks and sleep states and see if that improves startup. If the problem still stays, try removing one graphics card. If that fixes it, either your mobo or PSU can't handle the transient power spike (most likely the PSU)

I had no problem with the 550. I guess the 650 could be faulty.
