The funny thing is, those power bricks you plug into the AC outlet convert that back to DC and various voltages (including 12v).
I’ve wondered for a while if we’ll start seeing more DC input electronics designed for setups like yours because there’s efficiency losses for both the DC -> AC step and the AC -> DC step.








I don’t think that’s a special feature these days. My Linux desktop has a suspend shut down mode and though I usually close down whatever I’m playing, I believe there have been a few times where I’ve forgotten that I had a game still running minimized but it resumed fine and the game was still running fine.
