I just bought a GTX1080ti + a similar corsair as an upgrade for my 3 year old Dell, it works like a charm.
If you have a PSU that big then that probably isn't the problem. I thought you might be using the PSU that comes with those extender boxes and they usually are very puny (250 W or so).

Do you use it for gaming or for CUDA?
Do you run the 4 GPUs in the extender?
