Not enough power cables

I have the above computer, it has 2 open slots for expansion.

1/1) PCI-E x1
(1/1) PCI-E x16

I really wanted a usb 3.0 card, so I bought this one:
http://www.amazon.com/gp/product/B00...?ie=UTF8&psc=1 (2 Port Rear & USB3.0 20PIN Internal)

I was able to fit it into the x16 slot fine, however I didn't realize the power cable connection it has is IDE, and my computer has SATA power connectors

I also didn't realize I didn't have any open power cables.

so.. I am wondering if something like this would work, so I can get power to my usb 3.0 drive.

unplug the sata power cable to my dvdrom and plug it into a splitter with 2 sata plugs:

plug one of those back into the dvdrom.. and plug the other one into a sata to ide converter cable:
http://www.amazon.com/StarTech-LP4SA...de+power+cable

which plugs into my usb card.

is this too much? should I just buy the first cable so I have 2 open plugs.. and return my usb 3.0 card and buy one that has a sata power connector?


Lastly.. I wanted to ask what the 20PIN Internal slot was on the usb 3.0 card?

Newer motherboards have the 20 pin plugs built into them, I assume the 20 pin would plug right into it.

It's not IDE. It's just a generic molex PC power connector.

I also didn't realize I didn't have any open power cables.

That's the common case with most big OEM PCs. Saves them a few cents.

so.. I am wondering if something like this would work, so I can get power to my usb 3.0 drive.

Yes. But, does it work without it? I would imagine it is to supplement it, but most devices will be fine with power supplied over PCIe (I think 25W for non-video cards), unless the card only gets port power by that connector.

A header for front USB 3.0 ports.

Do you have any of the molex connections in your computer (these are the larger ones with four connections, not the flat SATA ones.) if you do, something like this should work:

If all sata cables, you will want something like this:
