Switch Box For HP Power Supply

I created this because I upgraded my power supply on my A8 to 400W from 250W because why not I had a couple of them laying around, and wanted to be able to switch it off, there is a few other options out there but I would have to do a lot more wiring and I didn't want the switch where it can be accidentally turned off.
The switch I used was a 125VAC 10A round 20mm and a standard 3 prong plug adaptor
