Affect of power to peripherals on motherboard

My husband and I were installing a new solid state hard drive into our computer. We were having problems with the power cable we were using so we switched cables. When we did, the computer wouldn't turn on. We unplugged and plugged in the main power cable and then it came on just fine and booted up...once (I think).

On either that first boot or the one right after that we got a hard-drive failure error and the system wouldn't recognized any boot devices. Late we found out that the cable we were using was incompatible with the power supply and we're fairly certain it supplied too much power to the devices.

We're pretty sure that the hard drive is dead and possibly the optic drive, as well, since we can't get a Windows 7 disc to read on the drive (we have another hard drive we're trying to install on).

However, the optic drive does spin up, but is not being recognized by the computer as a boot device. We're in the process of getting a cheap optic drive that we can test to see if that's the problem.

In the meantime, is it possible we fried the SATA ports on the motherboard by using the wrong power cable?

Any tips or information you have would be greatly appreciated.

Update: We swapped out the optic drive and it found the Windows install disc. I'm going to keep this thread open until we get everything up and running just in case we run in to other problems.

Power cable incompatible with the power supply? That's weird, I've never heard of such a thing/issue. If it fits into connector it should be fine, especially if it's SATA power connector (even if it's molex it should still be ok).

Maybe I am mistaken, but I thought certain cables carried a higher voltage than other cables and if you mixed them up then you could potentially have problems. Maybe there was a different problem with the cable, but we definitely had issues when we installed the new cable.

What I'm really concerned about is that it caused problems with the motherboard.

Drive power cables all provide same voltage as per their standard specification. Cables that carry unsuitable voltage cannot physically be connected to the drives, but only to their appropriate sockets (such as motherboard socket). It could be that the power supply rail is faulty (if that PSU is of multi-rail type).
