Making an adapter to run my cordless drill from ATX PSU

Recently I came across a video (    • ATX series: ATX Power Supply Mod for Handr...   ) on how to run a cordless drill with ATX PSU. I have multiple cordless drills with broken batteries and I never remember to charge those that have a working battery. So this seemed like a great idea. However, I decided to change few things for my own version. My local flea market usually has ATX PSUs with a price of just 1€. So I picked one with high enough power ( 450W, 19A at 12V) so that I don't have to modify it. Then I just used a normal 20pin connector to make an adapter which turns the PSU on and used 4pin connectors to get 12V out of the PSU. This enables me to easily change the PSU if it breaks. In addition, I didn't want to modify the drill itself as I still want to use it with a battery once in a while. So I disassembled a broken battery and connected power leads to the power terminals. Now I can use the drill with battery or ATX PSU. The 12V provided by ATX PSU is actually a bit low for my 14.4V drill. However, that mainly seems to affect the speed. The torque provided by the drill seems to be enough to drive some screws and drill some smaller holes. At least it's better than empty or broken battery. Additionally, my drill seems to use less than 10A of power so I added a 10A fuse just in case to protect the ATX PSU. 20pin ATX connector, eBay: https://ebay.to/3lrVgEA 4 pin Molex plugs, eBay: https://ebay.to/3xoOv93
