Hello, I got a Dell XPS 7100. I want to put a second HDD in it, i was looking at maybe a 1TB WD black. Anybody know if this mobo supports SATA 3.0?

No mention of it having SATA3, but SATA3 drives are backward compatible anyway, though transfer speed will be limited to whatever SATA spec the PC has.
You might also have to configure a jumper on a SATA3 drive to allow it to work on SATA or SATA2 controller.

Hey guys, thanks for the speedy reply. Glad to know these are backward compatible. Do you think the powersupply can handle another HDD i know its already pretty limited as i have the 1090T and the 5870?

According to this benchmark, > four-and five platter models. Note that unlike most hard disk specifications, power consumption normally is higher for drives with more platters even within the same family--since they have more mass to move, more power is required to turn the platters. Many manufacturers just quote an average for the whole family, but IBM generally doesn't:

I would say the PSU could handle the slight power draw.
