Thanks Ron, Problem solved. Your are correct in that I should have been looking for modular cables that connect directly to the card. Another person on another forum also advised to forget the adaptor cables from Gigabyte and look for two direct connections from my Seasonic PSU, which I have subsequently found and it is now powered up and working. Cheers, -James

Unless someone has already taken the plunge with the graphics card power wiring like this, I am reluctant to take the risk myself - I will sit on my hands until I get a reply from Gigabyte support or someone can convince me that it is meant to be that way. The Seasonic PSU pinouts conforms to the usual ATX 4 pin Molex peripheral power connector standard so I don't believe there is any issue on that side. -James

Attached is a photo of the four connections, the white female connectors are from the graphics card. The photo is not ideal but hopefully you can see that the red wire from the graphics card is connected to pin 3 in each case and that the red wire from the PSU is on pin 4 on each of the black connectors. So the connections are: From PSU --------> GTX 670 OC card Pin1 +12V DC Yellow wire -----> Yellow wire Pin2 Common Black wire -----> Black wire Pin3 Common Black wire -----> Red wire Pin4 +5V DC Red wire -----> N/C Gigabyte support should be back at work on the 17th after the Chinese New Year break, so I will refer this issue to them. I was hoping that someone on the forum might be able tell me quickly if this adaptor cable wiring was normal for this card (GV-N670OC-2GD) or not. -James

You are correct in that there are potentially 8 pins associated with each of the adaptor cables. I forgot that each of the two adaptor cables splits into two 4 pin plugs which are then connected to cables coming from the powers supply. The graphics card only uses 3 of the 4 pins in each plug and every one of these 4 plugs has this same issue of the red wire being connected to the black wire on power supply plug. -James

I am installing a Gigabyte GTX 670 OC Edition card in my new build and I noticed that power adaptor cables that came with the card do not seem to match the color coding of the cables from my Seasonic power supply. The Seasonic power cables have 4 pins: Pin 1. yellow = 12V DC Pin 2. black = Gnd or common Pin 3. black = 2nd Gnd or common (presumably associated with the 5V DC) Pin 4. red = 5V DC The two graphic card adaptor cables only use 3 pins on each. The yellow and black wires/pins match with Pn 1 Pin 2 OK ,but the red wire is connected to Pin 3 which is the second black wire from the power supply. The fourth pin is lefty empty. Does anyone know if this wire color missmatch is normal? I cannot think of any logical reason why this third red wire would need to be grounded. -James .

Have you tried re-running the Ezdoc Aircraft Configurator Tool - that has fixed some strange behaviour with external views for me on several occasions. -James
