Default Power Supply

I recently purchased a tire truer that required a 12 volt power supply to drive it. i tried to onvert an ATX computer power supply, but my conversion didn't go well.

Can anyone recommend an affordable power supply?

The other gentleman that recommended the p/s that runs I-charger its really under power. That charger is only rated up to 10amps max. I really dont know. To run a truer it is recommened to run 13.8v with 20-30amps constant. I've been using a Pyramid 25k since '93 with no problems. Truer never jammed. And its a Hudy Truer. Expensive p/s but worth it. Pyramid p/s I'd recommend.

What did you do wrong?

Sometimes the 5V and 3.3V need a small load to makew the 12V regulate properly.

This is your best (cheapest) route. I have one myself and it's very simple to setup yourself. The HP DPS 600PB is a server PSU that can be purchased from eBay for $20. There are lots of great tutorials on how to set them up as a power supply. Hope that helps.
