Chris and Phil,<br> <br> The last PC power supply that I purchased came with a 24 pin connector and the obligatory 24 to 20 pin adapter cable. I didn't check the pinouts for compatibility, but based on my experience adapters are available.<br> <br> http://www.endpcnoise.com/cgi-bin/e/00444.html<br> <br> 73<br> <br> Dan N4XWE<br><br><b><i>"Christopher T.

this header is not pin compatible with the 20-pin<br>version; the latch is in the wrong place and the pin across from #8 is<br>NC instead of -5VDC as specified for the 20-pin connector in the ATX<br>v2.1 spec <br><http:>.
