Default RE: How to convert an ATX power supply to rc use

Here is my PS:


[link=http://www.putfile.com/pic.php?img=6440642]Power Supply[/link]




I did the mod using the new P4 power supply. I get 12.15v without a load. When I add a load, it goes down to 11.95v. Therefore, I added a 10ohm 10watt sandbar resistor between a red & black wire and it stays at 12.30v with a load and w/o 12.5v. I added (2) 10ohm 10watt sandbar resistors in parallel and get 12.65v w/o load & 12.5v with load.

Since all the yellow, black, & orange wires were already soldered to the front bracket, I just heated up the solder and pulled out the pins. Then I drilled out the opening in order to fit in the banana post (Radio Shack Model: 274-718) Link: Banana posts . I used the existing solder and covered up the hole then added more around the post. Finally, I used the nut that came with the post and screwed it on to make a stronger hold.




Final product:


I noticed that the sandbar resistors get really hot.
*Question - Is there a way to keep a load without the excessive heat from it?
