It's a low profile card and I don't remember it needing any power being plugged in. To be fair, I think this card is overpriced for whatever performance you would get out of it. That is especially considering I only use it for 2d acceleration. But I needed the card because I could not get displayport from the motherboard working - I suspect it is the particular CPU. Regardless, my entire outlay for this machine was the price of the graphics card.

It is fairly quiet, but I've never heard it really ramp up.

I do vaugely remember the card NOT coming with the shorter edge connect (metal L bracket thingy). Need to look back there and see what I have going on.
