ATX Power Supply Breakout Terminal Block Frame

prusaprinters

<p>We began like many makers and used whatever we had laying about the shop before ordering parts. &nbsp;One of our early questions was how we could use the old ATX power supplies we had laying about. &nbsp;ATX power supplies provide hundreds of watts of precious 5V and 12V power, so you can hang all kinds of stuff off them. &nbsp;We came up with this solution.</p><p>The 3d printed part here is really simple. &nbsp;It's just a plastic frame into which you can screw everything else into. &nbsp;You simply plug your ATX power supply into the breakout board that is screwed into one end of the frame and then pull power from there to whatever terminal you want.</p><p>We pull uniquely pull 12V off these supplies. &nbsp;We've got one terminal block set up as ground, one as 12V, and the four small ones are available for use.</p><p>Given the size and shape of this frame, we may have printed it solid. &nbsp;If not, then it's probably the standard 2 perimeters, 20% grid infill. &nbsp;The holes have been designed to take the screws directly and have them create their own grooves.</p><p>&nbsp;</p><h4>Bill of Materials:</h4><p>(includes affiliate links)</p><figure class="table"><table><thead><tr><th style="width:40px;">No</th><th>Part</th><th>Notes&nbsp;</th></tr></thead><tbody><tr><td>1x</td><td style="width:165px;">ATX Breakout Terminal Frame</td><td>3d printed</td></tr><tr><td>1x</td><td>ATX power supply</td><td>Pull one out of an old computer if you can. &nbsp;You can find a cheap one for $30 if you search. &nbsp;Just make sure that the cable harness is either pre-attached or else you've got one.</td></tr><tr><td>1x</td><td>XH-M229 board</td><td>This is a generic board that's available from a number of suppliers. &nbsp;We picked <a href="https://amzn.to/3O5Eoyr">this one</a> because it met our cost/number needs at the time we ordered it. &nbsp;I'd bet money they all come from the same factory. &nbsp;$8.</td></tr><tr><td>2x</td><td>12 position terminal block</td><td>Again, these are all over the place from different suppliers. &nbsp;<a href="https://amzn.to/3aEDmLR">The pack we ordered</a> had 5 with both red and black barrier strips for about $13.</td></tr><tr><td>4x</td><td>3 position terminal block</td><td>Same as the above re: suppliers. &nbsp;We ordered a <a href="https://amzn.to/3ANAtTH">5-pack with barrier strips</a> for about $10.</td></tr><tr><td>6x</td><td>M3x6</td><td>We purchase most of our fasteners from <a href="https://www.boltdepot.com/">Bolt Depot</a> (in the USA, non affiliate) because we buy a lot and they're well priced (not affiliated). &nbsp;If you just need a small amount look for something like this <a href="https://www.amazon.com/dp/B071G2T6DV?&amp;_encoding=UTF8&amp;tag=originate3d01-20&amp;linkCode=ur2&amp;linkId=10dbd3337a88b3ef67a604848f79a59f&amp;camp=1789&amp;creative=9325">M3 cap head screw assortment</a>. &nbsp;It's way more expensive per part but we've gotten these kinds of assortments when we need something we don't normally stock and need it right now.</td></tr><tr><td>12x &nbsp; &nbsp;</td><td>M3x10</td><td>&nbsp;</td></tr></tbody></table></figure><p>As always, if you're patient you can order parts from China through AliExpress and save some money. &nbsp;Great if you know a month ahead of time what project you want to work on.</p>
