SFX to ATX PSU Power Supply mount adapter with optional fill or drain port water cooling

prusaprinters

<p>This project was inspired by a small water-cooling project in a Thermaltake Tower 100. The TT100 case has support for full size ATX power supply, but I wanted a water-cooling system with the following:</p><p>-a drain port for flushing out the water-cooling system<br>-a design to help bring the fresh air outside of the case through the PSU<br>-support the weight of the PSU<br>-minimal modifications to the case, so it can be re-used in the future<br>**Pass-through port will require come modifications depending on the case.</p><p>The PSU that was modeled after was the Corsair SF600 SFX. &nbsp;Measurements were used off the SFX standard for case mounting holes. &nbsp;Fan and switch placement were based on the SF600. &nbsp;Please refer below for possible compatibility for other models.</p><p>**SFX standard 125x100x63.5mm (WxLxH). This is what I have based for my design.<br>**SFX-L is a longer standard 125x125x63.5mm (WxLxH). &nbsp;I have seen some variations of this. &nbsp;Some of my models will not look or work correctly with SFX-L or other variations of SFX standard.</p><p>Build of Materials (BOM)</p><p>3 x M3 Brass inserts (4-6 mm in length)<br>3 x M3 screws length will depend on your brass insert and your computer case</p><p>3 x UTS 6-32 screws. These are your standard PSU screws. This number could be 3-6 screws depending on your PSU and/or bracket, these go through the plastic into the PSU.</p><p>Printing Instructions/Recommendations<br>-make sure your printer is calibrated. &nbsp;I have allowed 0.15mm tolerances on the insides of SFX sections.<br>**If you are unsure if the fit will be right for you, I recommend printing either SFX2ATXFlush or SFX2ATXFlushPort to test fit. I find ABS shrinks, so you may need to scale to 100.1%.</p><p>Support Settings<br>Following models do not require support:</p><p>SFX2ATXFlush&nbsp;<br>SFX2ATXFlushPort<br>SFX2ATXHalf&nbsp;<br>SFX2ATXHalfPort</p><p>Following models may require support depending on your material, and over hang abilities of your part cooling.</p><p>SFX2ATXCircle<br>SFX2ATXCirclePort<br>SFX2ATXLoft&nbsp;<br>SFX2ATXLoftPort</p><p>Additional Print settings<br>20% infill should be enough<br>Infill pattern Gyroid<br>3-4 walls/perimeters</p><p>Material<br>I personally would recommend either PETG or ABS depending on if you are able print these materials as temperatures in the case may get too close to glass transition of PLA. &nbsp;PLA you could risk deformation long term. &nbsp;PETG will be the best in class as you can use active part cooling for the over hangs in the circle models, and still have some temperature resistance.</p><p>I choose to print the SFX2ATXCirclePort I used ABS, Brim, 20% infill, 4 walls, and Gyroid infill pattern. &nbsp;I did attempt the Loft, but the bridging with ABS without cooling, but the results were not pretty at the bridge.</p><p>Assembly Instructions<br>1) Install your 3 x M3 brass inserts into the plastic holes from the back of the model. These locations will have the plastic at 7mm. &nbsp;Use pictures as reference.</p><p>2) If you are using a Pass-Through fitting it would be a good time to install and tighten while PSU is out as you may need to 'finesse' the fitting or hole. &nbsp;Additionally testing the fittings, and/or shutoff values and try fitting the whole assembly into your case to make sure this part will work for you.</p><p>3) Install yours with 3 x UTS 6-32 screws reference picture to fasten SFX PSU through this model. Try another test fit to be sure clearances are to your liking.</p><p>4) Mount this model to your case or PSU adapter for your case. This will require 1x UTS 6-32 screw to go through the case (or adapter), through the model and into SFX PSU, and 3 x M3 of the length required to go into through the case (or adapter), and thread into the M3 brass inserts.</p><p>Possible Uses<br>-SFX PSU to ATX PSU<br>-SFX PSU to ATX PSU with drain port via pass-through fittings.
