ATX Bench Power Supply

thingiverse

This is a case for a bench power supply that uses a standard ATX computer power supply and a DPS 5005. I really wanted to make a cheap bench power supply for use with my electronics project. This design allows you to use the 12v, 5v, 3.3v from the ATX PSU and the DPS 5005 for a variable output from 0-11.1V. The DPS 5005 gives you constant voltage and current modes, as well as various protection features. I hot glue the led, usb jack and nuts in place. Then used quick disconnects for the on/off switch and ring terminals for the banana jacks. The led and usb connections were soldered. <b>Parts List:</b> <ul> <li><a href="https://www.banggood.com/DPS5005-50V-5A-Buck-Adjustable-DC-Constant-Voltage-Power-Supply-Module-Integrated-Voltmeter-Ammeter-p-1062473.html">DPS 5005</a></li> <li><a href="https://www.amazon.com/gp/product/B00UHFF2ME/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1">Banana Plug Jack</a></li> <li><a href="https://www.amazon.com/gp/product/B01N2U8PK0/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1"> On/Off Switch</a></li> <li><a href="https://www.amazon.com/Uxcell-a13081900ux0112-Female-Socket-Connector/dp/B00H51E7B0/ref=sr_1_1?ie=UTF8&qid=1500922307&sr=8-1&keywords=female+usb"> Female USB Socket</a></li> </ul> I got these at Home Depot, but here are some examples for reference. <ul> <li><a href="https://www.amazon.com/Gardner-Bender-10-106-Vinyl-Insulated-Crimp-type/dp/B000LNOJYY/ref=sr_1_9?ie=UTF8&qid=1500921987&sr=8-9&keywords=ring+terminals">Ring Terminal for back of Banana Plug Jack</a></li> <li><a href="https://www.amazon.com/Install-Bay-BVFD250-Connector-100-Pack/dp/B005HQ4T5E/ref=sr_1_20?s=hi&ie=UTF8&qid=1500922073&sr=1-20&keywords=female+quick+disconnect">Female Quick Disconnect</a></li> <li> four #4-40 x 3/8 in screws and nuts</li> </ul> <ul> <li>Rubber Standoff, I had some old ones laying around.

Maybe. </font> It seems newer power supplies are stable without a load on it, but if you use an older one you might need this. If most of your power is on the 5v rail, you need about <b>10Ω 2.5w</b>. If most of your power is on the 12v rail, you need about <b>24Ω 6w</b>. </li> </ul> <b>Tools:</b> <ul> <li>Hot Glue Gun</li> <li>Soldering Iron</li> <li>Wire Cutters/strippers</li> <li>Crimpers</li> <li>Screw Drivers</li> </ul> <b>Good References:</b> <ul> <li><a href="http://makezine.com/projects/computer-power-supply-to-bench-power-supply-adapter/">Make: Turn a Computer Power Supply into Bench Power</a></li> <li>Search Youtube: "GreatScott!
