Desktop Power Supply ATX conversion (corsair)

thingiverse

I created a case for a PC ATX power supply conversion. Credit to helping me learn which cables do what goes to DroneBot on youtube here: https://www.youtube.com/watch?v=n_A-jkpjpcM&t=2146s The unit can do 62 Amps 12V DC or 30 Amps 5V/3.3V DC or a mixture of all three. This is considerable more than DroneBot's exmaple so don't follow his guide to the letter if you want to get that much current out. The unit also has an integrated combination voltmeter and ammeter. https://www.amazon.co.uk/gp/product/B078TGKH2S/ There is space for a minimum load resistor in the box but upon testing I found that it wasn't required for my device. This will be dependant on the voltage vs current draw curves that should be available for your particular model of corsair PSU. This may fit on other PSUs too but I have only tested it on corsair styled ones. I have supplied 2 test files called PSU Front Case (front panel test) and PSU Front Case (size test) that you can print in 30 minutes to make sure that the connectors you have purchased actually fit and that the whole unit fits around your PSU before committing to the huge print itself. If the sizes are off, I have also supplied the OpenSCAD files. I haven't really written these well as I didn't think I'd be sharing them so if you have issues working out which values to change let me know and I will help. I have additionally supplied the corsair 24 pin (10+14) pinout diagram as this varies from DroneBot's description. The triangle leading edges are there to reduce required supports. Provided your printer can print at 45 degrees without sag the supports for this are really easy to remove. You do need to use bed supports though, it won't work without them. The connecting rods are M6 threaded rods with nylocks on one side and thumb screws on the other, but you could just put nylocks on both sides.
