Question How to power an SSD?

[Boblobb14]

I'm thinking of getting an SSD to put my os (Win 10) and some games on, however, I don't know how to power it. It will be replacing an Optical Disk Drive which was powered by Slimline Sata, and the new SSD will be powered by normal sata power, so can I get an adapter from slimline Sata to normal sata, or if not, can I get a pcie expansion card for a normal sata power cable? Also, how would I transfer my OS to the ssd, and I've also seen that it says to connect the drive with the OS to sata 0 on my motherboard?

Edit: I forgot to mention that for some reason my current HDD is powered using a normal sata power, but that was extended using another male sata power plug, so is there enough power to power both a 1tb HDD and a probably 240gb sad from 1 sata power cable with an extension

Ok...now the SATA power cable(s) attached to the PSU.
You have one for the current drive, correct? Is there another one just like it, possibly an extension off that same cable?

There is one being used as an extension for the other drive but I wasn't sure if it had enough power to power an SSD and a hard drive
Edit: I didn't make that clear, there is a free one but it is powered by the same wires as the other one, so 2 connectors from 1 wire.
