connecting a PSU to a board which doesn't a have 20 pin connector
Hey, I have a micro sized board which has no connection for the ATX 20 pin connector but the manufacturer states that it can be used with ATX.
Connections on the board are a standard four pin Molex and an "external ATX control pin" There is a picture here if it helps
The three pins for the connector (white 3 pin connector to the right of the purple circular thing) are labeled ground, power on and always 5V. The instructions from the manual state
Manual available here
This CPU board can support an advanced soft power switch function if an ATX power supply is used. To enable the soft power switch function:
1. Take the specially designed ATX-to-PS/2 power cable out of NC-674ís
2. Connect the 3-pin plug of the cable to EXTATX (ATX feature connector).
3. Connect the power on/off button to PW/ON. (A momentary type of
button should be used).
I guess the ATX to PS/2 cable is not actually what it means, as it just has a 3 pin connector which connects to the board and has a 3 pin female plug on the end.
I've tried connecting the cable to - ground pin to black from PSU, always 5V to Red from PSU but am confused where the power on should connect to. Baring in mind I am using the PSU on a desk, so the green wire is shorted on a ground to give it power.
I manage to get the system to POST, but every time it tries to boot into windows it resets and I get the "start in safe mode" option on the next boot up with the reason being "power faliure" so I'm a bit stumped really.
Other specs that may help someone help me are...
Not running a power switch as it isnt' required as the board is getting power
Screen - LinITX - external power from its power supply
Hitachi travelstar 2.5" drive
200W PSU - known working correctly
Any help would be great :)
