It was the first major change in desktop computer enclosure, motherboard and power supply design in many years, improving standardization and interchangeability of parts. Maybe I shoudl buy a second spare just in case though.Comparison of some common motherboard form factors (pen for scale)ĪTX ( Advanced Technology eXtended) is a motherboard and power supply configuration specification, patented by David Dent in 1995 at Intel, to improve on previous de facto standards like the AT design. Moving the bottom pin in that image to the top slot and moving the +12V pin right next to it seems to be the correct answer. I used a multi-meter to continuity test the 5 fan pins and using another online guide I determined that there was continuity between the fan side pin 2 and the pin on the other end of the connector. Apparently the way I had it was connecting power and ground to the signal RPM & PWM pins, which is why the PWM chip exploded. Plugged it in the other way, and although I have fried the control portion, nothing is melting or popping any more. This is such a minor part of my project that I am already regretting choosing your products since apparently you have decided not to document them any more. I am following online pinout guides like this one.Please let me know before the second controller arrives. You could save everyone a lot of trouble here by using cables with the standard IEEE color scheme, although I am sure these all black ones are cheaper. On the 4 pin connector as it sits in the controller looking top (side with the buttons) down I have the following left to right: I have this thing wired up to a molex and have tucked the unused signal wires into the shield that came with the cable. Already fried a controller and it takes almost a full week to get another one. I also need the pinout for the 4 pin header on the north (opposite the 5-pin fan connectors) side. ![]()
