2U Power Supplies Shelf (for KWS rack)

Part of the KWS Rack v2 system

What is this?

This is a 2U module that stores all your rack’s power supplies in one clean place.

It’s designed for high airflow + tidy wiring:

• The front is a printed mesh/net (minimal, clean look) that lets air flow into the rack.
• Inside there’s a vented shelf where you can stack your power supplies.
• In the middle of the shelf you can secure PSUs with zip ties.
• Along the back edge there are cable wrap tabs so you can coil leftover cable length neatly and keep the rack organized.

Airflow & cooling

• The module is built around front intake airflow to help cool the PSU stack.
• If you want active cooling, you can mount 2× 80mm fans behind the front mesh (optional).

Note: In the photos you may see fans, but the default front panel is just a mesh/net.

Hardware / Assembly

To mount the shelf to the front panel:

• M4 screws + nuts (use the holes in the shelf and front brackets)

PSU mounting:

• Use zip ties through the shelf openings to lock power supplies in place.

Optional upgrades (recommended)

Lightbox (looks amazing)

In the middle I’ve got a KWS lightbox with a WLED-controlled LED inside.

Cable management mounts

For clean routing and strain relief, use my cable mounts

Back cable pass-through

On the backside I used one of the “brush cable management” panels on MakerWorld to let cable bundles exit cleanly.

This is one more module in the KWS Rack v2 ecosystem.
