Power Supply information
« on: February 24, 2015, 10:09:01 AM »
Hello all,
I've owned several PC-FX over the last 10 years. I bought and sold many. I never had issue with them.

The last one I have (I bought 2 at the same time from a Japanese reseller) was said as JUNK.
I found out what was the issue: the power supply.
First I changed the main fuse (2.5A/100V) with a euro one (2.5A/250V, I live in France current is 230V/50Hz) but it kept blowing (don't really now why). So I start planning to create my own power supply that would fit in the console and that would be compatible with 230 and 110V (as almost all recent power supplies).
However, as I don't own a working PC-FX , I can't figure out what is the pinout of the two connectors that give power to the mainboard (CN1 and CN2 on the power supply board).

Does somebody in here knows or maybe can help me by checking the voltage on pins?
Maybe someone has a junk PC-FX (with a working power supply) and would either lend or sell me the power supply?

Thanks in advance

Hello,
A friend of mine has a working PCFX. I managed to get it this evening.

I found what are 8 pins on 9...

On the last one, it seems that there is some current but really low voltage (0.1v).
Here is the layout
CN1
1    2    3    4
5v  9v   M   M
CN2
1    2    3    4   5
5v  9v   M   M   ?

Pin 5 seems it's linked to power switch (as on the old AT power supplies).
