I brought a SSD last week that supports SATA III. I wish to connect it to my PC but I have no idea whether my PC has SATA II or SATA III. I can provide any details or screenshots if needed.

Motherboard: ASUS M5A78L-M/USB3
Chipset: AMD 780G
Processor: AMD FX6100
OS: Windows 8.1


Your motherboard only supports SATA II.

You can find this out by doing a simple Google Search for the motherboard and following the link to the specification page on the ASUS website. It ways you have "6 x SATA 3Gb/s port(s)" and SATA 3Gb/s is SATA II. (SATA differences)

    Of course, your SSD will work on a SATA II port. Just not as fast as it would on a SATA III port. – Jamie Hanrahan Aug 4 '14 at 19:56
