My latest project 😁
It isn't exactly
PC Modding, but it is still modding. I came across some interesting guides online. I wanted to build a test PSU—something I could use for testing fans, showing off some LED lights on the fans, and playing around with some low voltage stuff.
A friend gave me this crappy 400W power supply, a real piece of junk hardware that I wasn't even sure would work 🤣
The plan was basically something like this:

Of course, why build a test power supply without doing a little bit of customizing? 😁

Then the cutting started. I stripped everything out and found the wires I needed. I took the green one (to signal that the "PC" is powered on) from the ATX bundle and a black one (any black one) for ground. I had to trim them down a bit for better aesthetics and ease of use, then join them together.

Messy.
The fan from the PSU was connected using red and black wires. Usually, the red wire in a power supply is 5V, but since I wasn't certain if that was the case for the fan, I played it safe and connected it to a yellow (12V) one. The photo basically shows everything I put together.
All in all, here is how it looks now:

That circle in the middle was a bit tricky; my scalpel didn't quite cooperate. 😁
