Is there a different voltage on the SATA port and on the Peripheral port?

When i was adding a graphic card to my computer (SLI) and changed my PSU from a 750w to a 1000w. I got myself into some trouble. The system is fine but my secondary harddrive and my optical disk reader doesn't seem to work now. (Can't find them on the BOIS or on the Disk Manager.)

I was wondering. Does a SATA port have a different voltage outage then from a peripheral port on the PSU?
In the beginning before i booted the computer, I used the SATA ports to supply my harddrives and one for the optical disk reader.
I booted the computer and saw the secondary disk wasn't there anymore. But later i saw there were some ports that says "PERIF" on some separate ports on the PSU.
Was i suppose to connect the power supply to the hard drives on those ports? My old PSU had both SATA and peripheral on the same ports, so i didn't pay much attention on what ports i connected the supply on. I used my old peripheral cables to supply the hard drives but i did change the pci-e cables for the graphics cards. (couldn't fit in the new PSU anyway)

Did i do wrong on connecting the SATA ports for the harddrives?

PC specs:
The new PSU: EVGA Supernova 1000W 2G, The old PSU: Corsair PowerSupply CX 750M 750W
RAM: (2x) G.Skill Ares 16GB DDR3 PC-12800 1600MHz 8GB
Motherboard: ASUS Z87-A - ATX / Z87
CPU: Intel Core i7-4770K
Optical reader: (This one cant find) ASUS DVD±RW 24X SATA Bulk Black
Graphic cards: (SLI) ASUS GeForce GTX 780 3GB DirectCU II OC
Primary Hardrive: (This one is ok) Samsung 840 EVO Series SSD 250GB SATA3 Basic Kit
Secondary harddrive: Seagate Intern Harddrive Desktop HDD 1TB (Cache 64MB / 7200RPM / Sata 6Gb/s)
 
Solution
You really need a voltage meter, so you are not guessing.

The only real way of diagnosing, computer problems is trying your parts in another working computer,
Or trying known working parts in your computer, one at a time.

Computer parts can bad even new.
Static electricity can kill them instantly, if you don't take precautions.
First
I would check the voltages on the power supply, with a multi-meter, while the computer is under load.

I looked into the instructions and you'r right. Peripheral ports are for the molex cables. I have now tested my SATA ports on the motherboard by connecting the primary harddrive into each one of them and they all work:D. So all the SATA cables and the SATA ports on the motherboard are working. I have also changed ALL the power supply cables but got the same results. I think both of them are actually dead:(

BUT how can it be? How can both a harddrive AND a optical reader be broken when i try to install a graphics card SLI and a new PSU? Any ideas? It's very difficult to plug in to the wrong port on a PSU. The cables are simply formed like that.
