External power for an internal hard drive

[artk1]

I have the Adpatec USBXchange adapter for converting a SCSI hard drive to USB. I have several internal scsi drives and adapters to convert to the USBXchage adapter but do not an have an external power source for the drives ( it is not being supplied by the USB port for these devices). Any known devices for converting the internal 4-pin power adapater to an external source ?
Thanks in advance.

Most Antec PSU's now come with an external molex power connection now but other than that ya'll just have to extend one of the internal ones to the outside with something like this (I don't know what ya'd use the switch itself for though unless ya had some internal lighting).

That's excellent. Thank you very much .
