Cheap 110v to 12v convertor

[milkbone]

I don't know how much 12v it supplies, but it's enough to run my 12v porch light on ct. It would depend on how big of a power supply it is also.
I work on and build my own computers so I have a few extra power supplies laying around, and use them to convert 110 to 12v. It's easy to do.

There is a simple method to "trick" the power supply to turn on:

1. Find the biggest bundle of wires with the 20 pin connector.
2. Find the green wire in that bundle - there is only one green wire
3. Connect the green wire to any black wire in the bundle - you can use a paperclip, a small piece of wire, etc. Or permanently splice and solder the wires together.

Then, just flip the power switch on the back and the fan will start running.

To get your 12 volts, find any one of the medium sized rectangular connectors with 4 wires. The yellow wire is 12v+, and the black wire next to it is 12v- (or ground).

Hope it helps
