Desktop Power Supply

thingiverse

I wanted a desktop power supply and had an extra computer power supply laying around. So I made an enclosure that I put the computer power supply into and bought a few items to make it nice. This supply has 5 volt output, 12 volt output and an adjustable 0-12 volt output. Instructions Simply print one of everything and two tops. (it actually is the top and bottom) the power supply can be mounted with the four 3mm x 10mm flat head screws. The sides can then be bolted to the top and bottom using the eight 3mm x 20mm bolts and 8 3mm nuts. (the nuts will be pressed into the top and bottom and will then not fall back out.) the front and back will snap into the grooves in the sides, top and bottom of the box. For the power connections I connected the black and green wire to the power switch and the yellow wire to one of the red banana plug posts (12 volt) and a red wire to the other red banana plug post. Both of the black banana plug posts are then connected to black wires. The hole below the switch is for a potentiometer that can be connected to a voltage regulator do it yourself kit. I connected 3 wires from the potentiometer leads to the places on the do it yourself voltage regulator board where the small potentiometer should go. The inputs to the regulator board are connected to the yellow and black wires and the outputs will go into the front in the bottom two holes. Items required: 1) Banana Jacks plugs (Radio Shack #271-661) 2) Switch (Radio Shack 275-0712) 3) Potentiometer (for adjustable power kit) 4) Power regulator kit (Velleman P1823) 5) Coolmax Micro ATX 300w Power Supply (http://www.frys.com/product/5841263?site=sr:SEARCH:MAIN_RSLT_PG) 6) four 3mm x 10mm flat head screw 7) eight 3mm x 20mm flat head screw 8) eight 3mm nuts
