Just hook it up to any, might as well hook it up to sata 1.
So we're it says sata 1 on my psu is that were I plug in my sata power?
What is your PSU?
I think the above two people are referring to the motherboard connection, so there is miscommunication. There are two cables: SATA and SATA power cables. A SATA cable, shown below, goes from the HDD to any port on the motherboard:
The next, the SATA power cable, goes from the PSU to the hard drive. It supplies it with energy, makes it work and run. I'm assuming you have a fully modular power supply from what you are saying. This means you plug in the cables that you use, and you don't need to plug in cables you won't use. Check your power supply manual for details on where to plug in the SATA power cable. In general, it's very intuitive, there are labels on the modular connector board. The SATA power end of the cable should look like below, whereas the PSU-in end is usually 4 pins.
