Hi, I have some -+ 12 volt supplies I have made for other projects. Where should I make the connections?? Do you suggest cutting and splicing the main power connector that goes to the ATX mother board?? This my first ATX computer and it seems that the power is switch on and off a bit differently than on an AT computer. The power off is just a software thing. -- Best regards, Angel mailto:angel@............ __________________________________________________________ Public Seismic Network Mailing List (PSN-L)
