Depending on the Operating System you use you can check for power failures.
On mac there's a tool called istatmenus, but I'm pretty sure there are also such tools available for Windows.

If it's an issue caused by the Y-Cable, the cables are too thin. But I wouldn't count on that. It could also be a software issue.

For more information you could check the log files

Well, it appears that Windows is recording a power failure... Kernel-Power. I'm just not sure about why. Again, 1200W power supply, brings me back to the Y-Adapters.
