i have the gigabyte z77 -ds3h motherboard,
it has 1x 6pin power connector right?(i dont find anything else)
and i want to buy the 7970 and im not sure if i need an 6 pin or an 8 pin connector for it
do you know which it needs?
A molex connection is flat and contains 4 pins. Molex connections are commonly used for powering case fans and IDE hard drives. To find out what one looks like, just google 'molex' and looka t the images.
You should use the manual to check what connections your motherboard has. Somewhere in there will be a diagram of your motherboard, and it will show things such as the ATX power connector, fan headers and any other power inputs. But to be honest if you looka round the CPU socket you should find that there is only 1 CPU power socket, whihc by the sounds of it you have already connected a cable to.
If you can give me the make and model of your PSU I can check and see if it will be able to power the 7970. You need to make sure that it is powerful enough to run the card, as well as have enought connections.
