    Do you need to connect the JP13 connector? (atx mobo, small 4 pin molex)

    I have a shuttle xpc that i'm going to use for my car pc project. I was looking at some Opus power supplies and it dawned on me that they don't have the little 4 prong plug. I don't know if I even need it or not so if someone that knows more than me can chime in, i'd appreciate it. I always thought they were for Pentium 4s but my board is for Athlons.

    yes, if the board has a connector it needs the power. You should be able to build an adaptor easily to plug into a molex connector and adapt it to the square 4 pin.

    I believe my OPUS does not have a 4 pin connector on the PSU itself, it has a master cable that plugs into the PSU which has the 4 pin connector coming off of it.

    I'm not positive though, and I can't check because of how it is currently installed.

    They really need to get a Smile that says "I did search" because I did and wasn't finding anything related. If you can search my topic and pull something up, go right ahead. Looks like i'll be getting an opus unless I can find another dc-dc ps that works with atx mobos.
