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 provide 62 Amps of 12V DC or 30 Amps of 5V/3.3V DC, or a combination of all three. This is significantly more than DroneBot's example, so don't follow his guide to the letter if you want to achieve that much current output. The unit also features an integrated combination voltmeter and ammeter. You can find this product on Amazon at 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 necessary for my device. This will depend on the voltage vs current draw curves available for your particular model of Corsair PSU. It may fit other PSUs as well, but I have only tested it on Corsair-styled ones. I've supplied two test files called PSU Front Case (front panel test) and PSU Front Case (size test) that you can print in 30 minutes to ensure that the connectors you have purchased actually fit and that the whole unit fits around your PSU before committing to the large-scale print. If the sizes are off, I've also supplied the OpenSCAD files. I didn't write these well as I didn't think I'd be sharing them, so if you have issues figuring out which values to change, let me know and I'll help. I've also included the Corsair 24-pin (10+14) pinout diagram, as it varies from DroneBot's description. The triangle leading edges are designed to reduce required supports. Provided your printer can print at 45 degrees without sagging, removing the supports for this case will be easy. However, you do need to use bed supports, as it won't work without them. The connecting rods are M6 threaded rods with nylocks on one side and thumb screws on the other. You could also put nylocks on both sides if you prefer.
