Default Power Distrubition Block Question

My question is I have a 12v distrubition block off my power supply so I can run more then one charger and so on. What I'm wanting to do is put in 5v jacks to run my lathe and tire warmers but not sure how or what I need to do this.

If there is anyone who has did this or knows how to do this I would really appreciate the help. I bought this a couple years ago from Jusbox and he offered a 5v jack in them and I didn't get it then and I've been kicking myself eversince.

Sounds like youre using a Computer PS, right? If so just seaqrch the threads for "Computer Power Supply" Theres lots of converstaion on the topic.

No I have a Rivergate 30 amp power supply but I have read some of the posts on doing a PC power supply I just thought I would try this before I went that way.

you could wire a 5v jack off the 12v using the right resistors in series.

Ya thats what I would like to do but I'm not sure how many in series I would need. I've seen the 1/2 or 1/4 volt resistors but i'm not sure if that is a 1/2 or 1/4 down on volts or a 1/2 or 1/4 total volts.

I would think that its down but I want to be sure before I start so I don't make it any harder in myself.

It would not be practical to use resistors for this application. You would have to know the exact current that you are going to draw in order to size the resistors properly. There are more complicated ways to do it that will work, but resistors are not the way.
