Hi,
Windows 7, 8 or 8.1?
Is this going to be your system drive with Windows installed to it or how is your configuration meant to be?
For the operative system to be able to see a new drive, it must be partitioned and formatted and assigned a drive letter.
Tip:
Create a New Partition on a Windows 7 Hard Disk
If you are going to install Windows and have the SSD as your system drive to boot from; temporarily unplug all HDD first and connect the SSD SATA cabel preferably to the motherboards first SATA 6 port, install Windows from scratch (with AHCI set to Enable in BIOS).
During Windows installation it will then create a partition and it will be formatted as NTFS.

After Windows installation, run Windows Update, restart, run Windows update again and restart, shutdown the computer, connect the hard drive, start the computer and immediately enter BIOS Setup and check the drives Boot priority, so that the SSD is first.
Plus make sure that you visit the computer or motherboard manufacturer and download all essential drivers with start from the Chipset driver.
