Computer power supply
Has anyone used a computer power supply to feed their DC charger? I have a PS laying around from a computer I disassembled.

I bought one of the newest computer power supplies that Micro Center had to power the newest generation of computers with the big processors. I then disassembled it and de-soldiered all the extra wire harnesses for the low current outputs and only used the two 12v high amperage lines, one 14amp and one 16amp to make a power supply for all my 12v tools!
Works great with no problems.
Much cheaper then buying a dedicated hobby industry power supply!

Sometimes I wonder what the deal is for the inflated prices... when conventional PSU's from computers do a much better job at lower prices.

Here's a link to a UK forum which discussed this very subject some time ago.
There are quite a few pages to wander through and keep you all occupied

Yes They totally work
Yea they are pretty easy to configure.
Just short the green wire to ground (black) and on the 24 pin connector there will be (if ATX PS) 2 wires that are jointed to gether at the plug usually a Orange and brown. Shorth those 2 and then Just use a few yellows for positive and a few blacks for negative and presto done. now if you want more current just get a sandbar resistor (10 Watt) anywhere netween 4 - 10 Ohms across the red to black and you will have true 12V and full Amperage that the PS can supply.
Currently I have one that will output 18A according to the sticker but I have run everything on it (2 chargers, tire warmer, lights, fan, laptop. pulling 15A with no issues of Voltage Fade

I think one of the RC Helicopeter magazines ran a "how to" article on this last fall. RCHeli October 2008?
