I bought a motherboard which has one 6Gb/s header and five 3Gb/s headers. It came with two 6 Gb/s cables.

I'll connect my SSD to the 6Gb/s header but can I connect my HDD to a 3Gb/s header using the other 6 Gb/s cable?

Yes. All SATA is backwards compatible. The SSD needs a SATA 3 ( 6Gb/s ) port but a mechanical hard drive although it might be labeled SATA 3 can't even come close to moving enough data to actually need a SATA 3 port. It just has a SATA 3 'interface' basically for marketing purposes.

Sorry I didn't communicate properly my bad. A little too many beers inside me I guess lol.

This is what I have.

1. SSD 6Gb/s
2. HDD 3Gb/s
3. 2 sata 6Gb/s cables
4. One 6Gb/s header on mobo. SSD gets this one.
5. Five 3Gb/s headers on mobo, HDD gets one of these.

Can I connect a 3Gb/s HDD to 3 GB/s header in mobo using a 6Gb/s sata cable?

First sentence in my first post: Yes. All SATA is backwards compatible.

That includes cables and ports. ;)
