How to use a standard atx ps on a compaq mobo
ok well I did tons of searching and wasnt able to find anything on this. I purchased a compaq ipaq off ebay for a rediculously cheap price. you can get used whole systems with a 733 for about 100$ or so. This is a good midrange system for people on the cheap. complete with case and all you need except for a power supply. Unfortuanately, compaq being seperated from the crowd, they used a non standard 14 pin style of atx. After awhile of searching the net I decided to call hp cust. support. After awhile of convincing I managed to squeeze the pinout from someone!! this is good for future reference if anyone needs it...

First column is compaq pin#, second is atx pin #. Use this guide to match up the pins from the power supply on your atx, to the one on the compaq. this * should* work fine.
1 - 1
2 - 6
3 - gnd
4 - 4
5 - gnd
6 - 19
7 - gnd
8 - 2
9 - 12
10 - ??
11 - 14
12 - 20
13 - gnd
14 - 10
the only pin that doesnt match up is pin 10 which is fan off. I have a feeling everything will work fine without that pin so if anyone needs to follow my lead there ya go :-) Enjoy your cheaper complete carpcs :-)
