I have an external sata usb caddy that I wish to fit internally. Just the circuit board, not the enclosure. I can connect it to a usb port on the mobo. It has its own power supply which connects via a PS2 port so I need to make a suitable adapter to power it from my PSU if possible.

Testing the output from its own transformer in order to make a cable I get reading of 12v and 5v both negative i.e. -12/-5 how can this be?

My concern is that if I connect it via a molex then it will get pos voltage and not work or damage something.

Why would you want to do that. Can't you just connect the drive to an internal SATA.

If I had a spare one then yes but I don't hence my asking.

OK that is as good a reason as any.

Would this help.

thanks alan. It looks like a PCIEX16 card which would be the ideal answer if it is.

Looks like its not viewing it again.

I have 3No PCIEX1 slots and 1No PCIEX16 available if there is anything else similar.

And 19 pin USB 3.

Motherboard is ASUS H81M-PLUS if that clarifies things a bit.
