12Vhpwr Adapters - more stress with higher power draw on 5000 series

With the Nvidia 5000 series approaching with a significant higher power draw then the 4000 series, cables, connectors and adapters are under even more stress. It would be awesome to have some tests of several adapters so consumers know what is safe to use in their setups. Are there already such tests? Or are test planned?

For me, im particularly interested in the phobya 12vhpwr 180 degree adapter. Do anyone of you know about test of it? Or reports of issues with this adapter?
