Can SATA 3 cables be used on SATA 2 slots?

[thepcgamer099]

I have found a motherboard thta i want but the problem is it has 2 sata 3 slots and 4 sata 2 slots but I want more than 2 sata 3 hard drives and a SATA 3 optical drive. Here is the motherboard I am hoping to get: http://www.eclipsecomputers.com/product.aspx?code=MBM-Z77AG43G
also would this motherboard support a MSI geforce gtx 770 twin frozr gpu? Thanks

Yup, the cable doesn't really matter.

Only thing is that the link will operate at the slower of the two endpoints' speeds. That's not an issue though, as neither HDDs or ODDs can currently max out a SATA2 link.

so would I be able to use a sata 3 hdd or ssd in a sata 2 slot on a motherboard? So will this make the hard drive slower if i plug a sata 3 hard drive into a sata 2 socket? Also what is a ODD?

ODD = Optical Disk Drive. DVD, Bluray etc.

It will theoretically, but not in practice. Nothing other than an SSD gets anywhere near the limits of a SATA2 port.
