Power only goes to one storage drive for new build

[Redsama]

So I've successfully built my first PC and every part works well except one small issue. I have an SSD with windows 8 on it and an HDD. The SSD and HDD are connected to the PSU with one cable (the cable has 3 power ports on it) and I can only get power going through one drive no matter how much I switch up the cable ports. Can someone tell me what I'm doing wrong?

Have you tested different cable?

Have you tested different cable?

The only other power cable I have is connected to the optical drive but I suppose I can swap those. You think the cable might be faulty?

Alright so I tried using the optical's power cable onto the HDD and the HDD worked but the SSD didn't. So I tried using 1 cable (shared) for the SSD and the HDD with the optical's cable unplugged...and it worked. Then I tried putting back the optical cables power but it didn't work. Seems like it refuses to have 3 satas running at the same time or something.

Am I able to switch around the power cables in the bios screen or do I have to restart every time?

It's good to power off when switching cables.
Does the PSU have more than one SATA power cable?

Got them all too work. It was just the power cables weren't pushed in enough I'm guessing.
