My first reaction to reading your problem was of a power-supply issue. It's typically when the going gets tough that a top-end GPU like yours will start drinking power and if the system diverts too much from the rest of the components you get a crash.
However, having said that, your PSU is a powerful one and you mention this getting worse when you change O/S version. Plenty of other builders have put together machines this powerful - and more - without the issue.
So ... Perhaps try that GPU in a different PCIe slot. I know they will be slower assuming you have it currently in slot PCIeX16 but it might be a valid check that the GPU can run in a lesser one with sufficient power (assuming you've checked the PSU leads and connectors etc). Hopefully there will be no configuration problems...
I might be way off mark but your problem sounds like power to me.
Good luck anyway
Hello, I also think it's a power problem. If I change gpu of slot... I should reinstall Sierra, multibeast or something else after?
I was about to do a new fresh installation of El Capitan, but now I think it is best to install windows to test if the hardware is good.
