I saw this picture while looking at overclocking guides and I wondered if I may have my power setup incorrectly. My GPU is currently connected exactly like the don’t do this diagram.
I seem to remember they started doing those daisy chain power connectors back in the SLi days. Take the GeForce 6800GT for example, which was a single slot card rated for 67 watts and had a single 6-pin power socket. You could safely drive two of them in SLi on a single 150 watt PCIe power cable. Hell they’d probably both run fine on motherboard power.
