Modding a PC Power Supply into a 12 Volt Supply for your DC charger You should be good to go as long as your charger will accept the 6A as being enough to charge your batteries! Open the PSU up and look at the wire colors, then you can determine which instructions to use. REMEMBER that you need to discharge the capacitors before use. The left over current in the caps can KILL you! |

Thanks for the info! I got it converted and wasn't to bad a task. A little time consuming but not to bad. I think with it being a bit small in output I'll just go with a charger that has it's own internal power supply. I don't want to run the risk of overworking the charger and killing the charger itself. Sent from my iPhone using Tapatalk |

Re: Modding a PC Power Supply into a 12 Volt Supply for your DC charger Reviving this guy... The AC side of my charger is starting to flake out, luckily it has DC input as well, the manual recommend 20A. I have a 700w ATX power supply, it has three rails of +12VDC rated at 18A each. I am trying to see if there is a problem will paralleling them up for a combined 54A of current, basically, just gain all of the yellow wires together. Or, I might go a safer route and just buy a 30A power supply off of Amazon... https://www.amazon.com/BMOUO-Univers...a+power+supply Thoughts? |

18 amps is enough as long as your not trying to charge 4 batteries at 5A at once. |

I treat batteries like the ocean, I rarely turn my back on them when they are charging. Plus, I have welder's gloves and a chemical extinguisher at the ready if anything decides to get unhappy. This PC PS is out of my poor old Alienware that developed motherboard issues. After 10 years of use I had gotten my money out of the machine, and happy I can re-purpose some of it. But, the PS is not a cheapy, as a result not built like a cheap PS, so to get at the main power distribution rails. It does have a very nice connector that plugs the whole mess into the PS, so I am just going to ohm out the individual 12v leads to figure out which go together. I'll likely wire everything into a project box with output terminals, I have a 10A PS, it will be nice to have a beefier PS on the bench. |

Hi, my friend, I have the same power supply as this one. I want to increase the voltage of it to 13.8v you have the scheme of how to do that. Thank you very much in advance |
