Another ATX Bench Power Supply This ATX PSU bench power supply combines some of the best features of other designs I found on Thingiverse : variable voltage unit, fuses, mini-voltmeters, USB,.... Features : Fixed 3.3 V, 5 V and 12 V terminals Variable voltage (0-12 V) terminal (from DPS5005 module) Two usb 5V ports Fuses on all + terminals external for 3.3, 5, 12 and var. internal in-line fuse for USB Bottom panel has a 'window' to allow you to read the ATX PSU specs. The eight 3D printed parts for his unit : Top- and bottom-panels Front- and back panel 2 Left-side panels 2 Right-side panels If your Right-side panel 01 is a little warped, you could print 4 extra little spacers and glue them on the inside (around the ventilator opening). All parts are printable on small-platform printers, no supports needed. Assemble using M3 x 10 mm. screws (conical shaped head). (32 pcs.) You will need : DPS5005 Programmable Power Supply Module (here) Blue or red mini-voltmeters (4) (here) 12V USB adapter (here) 10 Ohm 10 Watt resistance Switch (here) 8 banana binding posts (4 red, 4 black) (here) 5 x 20 mm fuses (5) (here) 5 x 20 mm fuse-holders (4) (here) in-line 5 x20 mm fuse holder (1) (here) 2 leds (+ two 330 ohm resistors) 2 led holders (here) ATX 500W PSU with silent 12 cm ventilator and SATA, Molex connector (here) soldering iron and screwdriver, multimeter. I used (part of) an aluminium heat sink from a broken icebox to mount the 10 Ohm 10W resistance on top of the ATX module (using some thermal silicone paste compound / thermal glue) Update 15-07-19 : new version of front-panel V2 Enjoy !
