I am asking this question because i have a mobo that has a SATA 1 cable,, if i bring a SATA 2 to it will it get any effect to it .

SATA and SATA2 hard drives can be used with any SATA controller. If the SATA controller can only handle 150mb/s then a SATA2 drive will function as a SATA drive. Also, any SATA cable can be used for either a SATA or SATA2 drive. Both drives and cables are fully interchangeable.

SATA I / II differ for the most part only in the theoretical bandwidth of the interface (i.e. SATA I 1.5Gbit/s; SATA II 3Gbit/s). There are minimal differencies but they are not in cables. The form and functionality of cables are exactly the same.
