New SSD undiscoverable when connected to MB.

So I setup and partitioned my new Kingston SV300 using my USB-Sata connection cable. But When I connect to an onboard Sata port, I get nothing. I cant even manually discover it in bios. Why is this happening? I've used every onboard sata port except the one that my current HDD is plugged in to. I've also tried 3 different sata cables, all with no change. Any help would be great, thanks.

Nevermind. Figured it out. I forgot I unplugged all of the Sata power connectors I wasn't using from the PSU. Stupid me. Thanks.
