Need help with choosing power cable for GPU

[cb600fshornet]

For what it's worth I ran a GTX280 (pulling 40A) on a PSU that only supplied 36A on a single 12V rail using a six pin, then using a dual molex to 8 pin adapter, and it worked fine for ages. The only reason it's not working now is because I killed it with static!

Dude the card is an asus gtx 750 ti oc 2gb
It says clearly that it needs only 150 watt on the box.
