I really hope you didn't combine all the red, blacks and yellows into ONE plug, because that is what it sounds like to me.

My boss bitched at me for making one of these at work a few weeks ago. He ate his words this week when it came in handy more than once. |

Using a PC ATX PSU is good but I highly recommend using a server PSU. For example, I have found out that the 12v PSU from MaxAMPs http://www.maxamps.com/Power-Supply-12V.htm ($79) PSU they are using isn't a in-house built but a server PSU from HP DL380 series of a server machine. It's a PSU series 135 with 575Watts with 47A on 12v rail. Exactly same spec shown at maxamps site. This is a extremely easy to mod PSU, in fact there is absolutely no modding required. Simply short some pins to allow it to self power on, solder some wires to its 12v pin + GND = DONE! Great part is... this exact server PSU can be found online for under $20.(refurb/Used) In fact, I bought mine at a local computer server parts store for $15 only. Even at near full load, 12v rail would not drop below 12volts too. Hardware wise, it is a absolutely solid... so no need to worry anything about that. So I guess if you want to buy from maxamps, you would be paying extra for pretty skin, pre-solder wire with plug, power cable and its great warranty service. It almost makes me want to get me a higher quality charger. Like... Revolectrix Cellpro PowerLab 8 , Or I'll just run two charger off it. Hmmm... imagine parallel charging 8 5000mah packs in 1hr (1C) !! or faster. Enjoy! Last edited by xxgg; 07-04-2011 at 03:15 AM. |

I just did this mod to a power supply. All the outputs show correct voltage. But once I hook a lathe to the outputs the power supply shuts off. Any ideas?

Binding posts finally came in. Finding a place that sells them for cheap was hard. SparkFun.com was the best place I could find and they only had black and red. Making the holes was a pain. Had to move the fan to the outside since there wasn't much room inside the PSU since it is from a tiny HTPC. Left some PC plugs to test HDDs. Anyways here are some pics: |

I ended up finding out that mine would only work if I left it off, plugged in my desired electronics then turned it on. I assume my resistor is not pulling enough wasted energy for the PS to see a drain. For now it works, I may fix it later. |

| The power supply shut off becuase it saw the connection as a short and cut off to save its self. Most PS will do that, just connect charger\lathe first.

All works very well. I use my PS to power my Battery charger, test electronics and to power my motor lathe. Here are some pic's. Thanks for all the info on this thread..\\ Pic's. |
