How to build a $20 47A power supply

[snellemin]

I was in the same boat man. I was seeking a simple high quality 40+A 12V power supply without breaking the bank. I also didn't want to spend too much time hacking a regular computer power supply. Nice thing is, that I work at HP and have access to the Server group and PSU group. I got to open a few PSU's up and asked the designers and engineers what the limitations where and what not. I went on Ebay and started inputting different HP part numbers and found the older stuff to be dirt cheap and easy to mod. Easy as in, not having to open up the Power Supply at all. I also found that some people on rcgroups have used the same power supply I have listed. I figured that 47A PSU is more than enough for the majority of the people and $20 dollars is more than affordable for nearly anybody in this hobby.
