I've never seen a riser like those before...those look really interesting. Anyone know of an online vendor selling these?
Technically, wouldn't padrino technically be an online vendor? I've bought stuff from him before and he's great to work with.
I haven't looked to carefully into the spec, but I know that with the risers using the Molex connector, they're definitely using both the 5v and the 12v power supplied - whereas this riser would only be providing 12v from the PCI-e connector, so presumably drawing 5v across the ribbon cable.
On my 6 card systems, each card generally draws about 1a at 5v across the riser molex connector... That's what steered me away from these solution combined with the fact it doesn't have mounting points, although I loved the fact they use PCI-e cables as that's a big hassle for my configurations.
