Summary

Another ATX bench power supply, inspired by https://www.thingiverse.com/thing:5894950 (thanks Maker-Y!), but designed from scratch. There is no need for cutting PS wires that you dont use - there is enough place inside between PS and housing to store them away (properly insulated). Behind the front panel some hooks are added for better wiring organization. Other changes are:

  • not using DC Power Supply Jack Socket Female
  • added two LEDs (blue and red) for indicating operating status
  • used 8 Ohm, 25 W Aluminum Housed Resistor as load
  • used VA meters for each fixed voltage output

Printing:
Printed with 0.2 mm resolution, 20% infill, supports needed for some parts. Front panel printed with filament change above 4mm (above layer 20) for texts and markings. Housing screws holes are printed small (if wider needed, just drill them out a bit), so any screw for plastic will fit. Part "top back" is made with extension (if you want to mount ATX breakout board between "top back" and "bottom back"). If your PS's vent opening is more on the left side use "top back-left", for right sided vent openings use "top back". Also there is "top back - wide" part for PS with vent opening at different position (it should fit for all).

Changelog:
V1

  • added fuse for USB circuit protecion, removed current labels for fixed voltages outputs on front panel, changed schematic diagram according to cbx_micha's comment (thanks!).
  • as user raymond008 pointed out A meters works correctly only for separated loads. For correct current measuring in circuits that use multiple voltages in same circuit, you will need different VA meters and different wiring scheme (more in comments - thanks raymond008!).
  • wiring diagram removed. Everybody should find out his own way to connect things together, according to his own needs. Not at last this site is about .stl files.
