yea i got one with the purchase of my Abit Nf7 mobo... never used it until recently with my new comp (in the sig) i got a great deal on a 160gb HD from staples, but it was IDE so i wanted to try to "make" it SATA... it worked fine, the one i have takes its own power source (the little connector used for the floppy's power)
Never had any problems thus far, no installation needed either
