No problem, I also found a pinout from hp, but the walk through on rc tech did a much better job than the pinout from HP.

Got both my ps done and charging fine both put out at least 15 amps. I know that cause one chrger is 7 amp max and the. Other is 8 amp max. Both ps will power them both fine. I spent around 15 bucks for everything at radio shack for both ps converisons. Thanks again for a great write up.

I snagged another PSU out of a computer that was getting thrown away at work. I think I'm going to convert this one over and actually use it at work. I need a 12v source other than a battery to test aftermarket radios that come in some of the cars we get (I work at a salvage yard, LKQ). I tell you though, this little converted PSU has come in very useful, aside from powering my charger. I used it this past weekend to power up an LED array I'm making; making a custom LED 3rd brake light for my truck. |

Here is my little power supply in action. Got it from a dead pc. It works like a charm! Last edited by halon; 11-14-2013 at 07:55 PM. |

i built mine about a year ago.added a 5v a tap few months ago to run my lathe. i run the same B6 charger above and a hobbyking 6-10 charger. both run at the same time no problem. i havent tried running the lathe with both chargers yet. i think its 14 amp on the 12v rail, dont remember what the 5v rail is. it came out of a old Dell PC Last edited by stanmondz; 08-12-2012 at 09:08 PM. |

Sounds like you actually have 2 12V 18A circuits in it, I would keep them separate if there are 2 circuits. | |

post a picture of the guts, you don't want to tie the two rails together. Just put 2 sets of posts to hook up multiple chargers

i tied both rails together on my charger and it is rock solid.. The more load i put to it the better it works.. Voltage never seems to drop.. Instead of a resistor i just used the second fan to create a load on the 5v rail

A "safe" current hand-to-hand is only 0.5 mA, not 30 mA! (Near the heart only 0.05 mA can be considered somewhat safe.) I work with medical devices on a daily basis, this kind of knowledge is part of my profession... Quote:

Here's mine that I built on a raining Saturday morning. Power supply - free Parts from RadioShack - less than $20. It was a fun build, got the USB ports from a PS3 unit that crapped out. Also building another one with the PS3 power supply. |

Also built one using a PS3 power supply and using the dual USB charging posts. I can leave this one on my toolbox. 12v @ 32a |
