Im just about to buy two hd6950 and I dont know how to connect them. I have a cooler master gx650 and it has two 4+2 pcie connectors so powering one card is no problem. But because my powersupply only has three molex connectors I cant just take two two molex to 6 pin adapters but what i could do is take one two molex to one 8 pin adapter and then take a 8 pin to two 6 pins. But woud that put to much strain on the powersupply?
sorry for my english

Your PSU should be able to run it but it will be pushing it hard.


What would happen if it wont be able to do it?

The power supply is not the greatest , it may run the 2 cards , but will likely fail quickly.

Best case scenario just the PSU dies. Worst case scenario it fries the system and burns down your house.

The B1 isn't the good one , get the B2 made by Super Flower.

Better quality with a single 12v+ rail.
