Hi,

I want to connect my AT psu( for fans only)to my ATX psu so that both will power up when I turn on PC. So far I found guides on connecting 2ATX or 2 AT power supplies. Radioshack sold me a relay that had only 4 terminals, but my AT psu already have 4 leads ( blue, white, brown, and black)going to the switch. Can anyone tell me what is the type of relay that I need? So far all I know now is that I need a 12vdc relay to hook up the 4 wires to 12v + ground from the molex of my ATX psu.

I was looking thru the Jameco catalog, and I am overwhelmed by the choices there. Now I am more confused as I do not know how to read the schematics.

Any help will be appreciated.

Thanks
