It does have Q connectors. One is already in use for the hd light/pwer led e t c and it's been so long since I've looked in the box, I'd forgotten there were 2 more in the pack.. one red, one blue. I've just ordered/received 2 new sata cables and there are 4 brand new ones in the box already D'oh!
I'll bet the new cards make things run very smoothly
