I always tend to over size my power supplies. I ran my own wiring in my house, so I actually have access to 220V power there! I bought a LR-30 to C13 power cord a while back (https://www.amazon.com/NEMA-L6-30P-C13-Power-Cord/dp/B004WODG6A/) so I could run my PC on 220V. I’m not sure it actually saves me anything, but I like the idea of having my electrical panel balanced a little better.
I am lucky enough to have wired my own house for data, so I have ethernet right at my PC Desk! (I also went a little overboard and wired for 220V power there) I’ve always preferred wired Keyboard/Mouse also, so hopefully those won’t be an issue. I have wireless headphones from my existing PC, which I’m hoping to reuse. They already work well with my existing Linux PC.
I love the idea of upscaling graphics on an emulator! Maybe I can go play through FF6/FF3 again!
Supposedly 220V is a little more efficient to step down than 110V? I’ve read a lot of articles about data mining where they run the mining rigs off of 220V in the USA instead of 110V and they gain something like 5% efficiency. They’re doing it with entire shipping containers full of PCs though. On my single PC, I’m not sure I can tell the difference at all. But I’m an Electrical Engineer by trade, so it makes me feel better that I’m more power efficient and have my panel balanced. I was running the 220V for my server rack anyway, so it wasn’t a lot of effort to pull one more circuit for my Desktop PC.
