Build your own EVbot for AMD cards
 

Requires a couple bucks in a parts and some software to get it running, so not exactly the same but neat nonetheless

you can use a EVbot for a ATI 5870 if you whant, all vga's that have Volterra VRM

this is where you connect of the 5870

now only one out of the 4 connections to the evbot seems to need +5v, +3.3v and gnd (please correct me if im wrong mate), so if your using a classified board then you can connect that to your evbot and the other 3 gfx cards dont need power...


with just 2 wires he takes your 5870 VCCD and Vxxx?? to 2.0v if needed :D
