3D Models for PC Power Supply Covers and Guards

This collection gathers STL files for covers, guards, and enclosures around PC power supplies. You can find parts for standard ATX units, open-frame supplies, and case power buttons. It helps when you need to adapt a power supply to a build or replace a missing cover. Polyzon does not confirm whether models are free, their price, license, official status, affiliation, safety or fitness. Check the current terms at the source.

«3D Models for PC Power Supply Covers and Guards»

Covers range from simple plates that close an opening to full enclosures with cutouts for sockets, switches, and fans. Some designs protect a power button on a PC case, while others wrap an open-frame supply or a bench unit built from a desktop ATX unit. The shape depends on the supply type and on which connectors or controls must remain accessible.

When choosing a model, check the listed dimensions and scale against your supply, and count the separate parts to see whether assembly is required. Look at whether the author notes support needs, screw holes, or fan openings, and review photos of real prints to judge the result. The material and settings on the model page give a starting point, but you may need to adjust them for your 3D printer.

To narrow the search, try terms such as PSU cover, power supply shroud, ATX enclosure, button guard, or open-frame supply cover. Related topics include cable management, case modding, bench power supplies, and printer power supply housings. Combining a supply type with the needed cutouts usually returns more precise results.

FAQ

Frequently asked questions

What measurements should I check before printing a power supply cover?
Compare the model's outer dimensions, mounting hole spacing, and opening sizes with your supply. The author's page often lists these values or shows them in a diagram.
Do power supply covers always need supports?
It depends on the overhangs and the orientation you choose. Check the model page for the author's notes and look at print photos to see how others oriented the part.
Can I adapt a cover designed for one supply to another?
You can scale or edit the model if the differences are small, but connector and switch positions must line up. Check the listed dimensions before making changes.
What is the difference between a PSU cover and a power button guard?
A PSU cover encloses or shields the power supply body, while a button guard sits over the case power button. Both appear in this collection as separate model types.
