Hooking up Hard-Drives to new PSU

My old PSU had only 1 SATA cable with 3 connectors on it. I had my C drive (SSD) and 2 1tb hard-drives plugged in to it with the hard-drives closest to the PSU and the SSD at the very end of the cable. The new PSU can house up to 3 SATA cables, each (in theory) with 3 drives. Using only 1 cable is a very tight fit getting all the drives plugged in, so I'd rather use more cables. But I have no idea if there are any restrictions on which SATA outputs on the PSU I should use. Does it makes any difference which of the 3 plugs on each cable is being used. Can I skip plugs on a cable (e.g. use the first and last and leave the middle unconnected? If nothing else, I'd like to put the SSD on a separate cable and spread the drives out a bit to allow better air-flow. (New PSU is a EVGA 750 GQ.) Can anybody help?

Is it one of those 15-pin SATA to 4-pin SATA things? Should not be a problem. In fact, the PSU may have included one or more cables with 4-pin SATA power ends.

If all 3 jacks on the PSU are labeled for SATA use, you can mix and match any way you need. Same applies for any multi-drive cables you attach. Use in whatever combination works for your setup. They are all just power cables.

EDIT: I assume the multi-drive cables you talk about (x3 ends) came with the PSU and the PSU can drive 3 drives with one such cable on a single PSU jack.
