Hi there, I'm intending to upgrade my pc with a secone 560ti (I already have one and I got this one for free).
But my power supply unit doesn't have enough ports to supply them both and I'm also not sure if 560W is enough.

Can you recommend one?
And do I have to do sth. else (like connecting them directly, i dunno...)

Thanks in advance(:

Well, it seems to be enough but thanks fo your answers anyways:P
