It probably depends on the number of other devices. Sharing with
more than one other device may cause problems. I have a BFG 6800 ultra OC
I had to configure my system so one power connector was only shared with one
other device and the other on its own.
Since then I've added a supply so the BFG is powered by its own supply.

Yes I'm running two supplies on one system.

At random times in windows my screen would
go blank and I would have to turn off my system
and restart it. After changing the power set up
I haven't had that problem.

This issue is way overblown. I've been tested my BFG6800u for weeks,
and it just doesn't matter how I split them off. I've used:
generic 300w
zalman 300w
tagan 480w
antec 430w

in all split-off/dongle configs, oced to 446/118 core/mem.
works fine .
