DIY 24W × 8 + 65W USB-C Charging Station from an Old PC PSU
I have a problem: over the past year, I rapidly accumulated devices. Tablet, smartwatch, AirPods, multiple phones, power banks, a laptop. Every single one came with either a slow charger or none at all. Stacking five tiny wall warts on a power strip works until it doesn’t. And good GaN chargers? They cost a fortune.
So I built my own charging station. Total cost: ~15,000 Ft (~$40). It has:
- 8x USB-A ports, each capable of 24W fast charging (QC 3.0)
- 1x USB-C PD port, capable of 65W, enough for a laptop
- A lab bench power supply (the SK120X module) for when I need adjustable voltage on the bench
- All powered by a salvaged (bought) 420W PC power supply
- Housed in a custom 3D printed case designed in Fusion 360 and printed in PETG

The guts
The heart of this build is a 420W ATX power supply I picked up on Vinted for a mere 2,200 Ft. It puts out plenty of 12V current, and I simply ran six 12V wires from the PSU bundle straight to the modules. No custom PCB, no buck converters, no fuss.
The modules themselves all came from AliExpress:
- 2× 4-in-1 USB QC 3.0 fast charger boards — eight ports total, each capable of 24W. These are the workhorses for daily device charging.
- 1× IP2368 module — handles the 65W USB-C Power Delivery for my laptop. Negotiates PD properly so I can charge with a single USB-C cable.
- 1× SK120X adjustable bench power supply — gives me a variable output for breadboarding, testing, or any random project where a fixed voltage isn’t enough.
The case
I knew this needed a proper home. I started with a Printables model for the SK120X case, imported it into Fusion 360, and modelled the rest of the enclosure around GrabCAD files of the other modules. Every cutout, every screw hole, every port position matches the real hardware.
The whole thing was printed on my upgraded Ender 6 in PETG, tough enough to handle the warmth from eight concurrent fast charges without warping. The hand-drawn texture of 3D printing fits the vibe.
Wiring: boring is good
There’s no secret sauce in the wiring. The PSU has six 12V wires coming out of its harness. I snipped, stripped, and crimped them onto the input terminals of the USB modules, the IP2368, and the SK120X. Grounds go to ground. That’s it. No switch, no fuse, no displays — just raw, reliable power distribution. Sometimes the simplest solution is the right one.
Why not just buy one?
A quality GaN charger with 4 ports runs 10–15,000 Ft these days. A 65W GaN with a single USB-C? Same ballpark. I wanted:
- 8 fast-charge USB-A ports
- A dedicated 65W USB-C PD for my laptop
- A bench supply on top
- Something that looks like it belongs on a desk, not a tangle of wall warts
At 15,000 Ft total, I got all of that, plus the satisfaction of building it myself.
