One option I’m aware of that nobody seems to consider is that in NA, the power delivered to the home is approximately 240v split-phase

Or component makers could...y'know focus a bit more on efficiency again so we aren't talking about shifting electrical standards just to play Crisis in a decade?

On a related note, there's still tons of homes with electrical circuits that are only 2 prong and don't have a dedicated ground wire. Better to encourage those to get replaced long before trying to get people to add multiple 240V circuits anywhere they think there might be a computer plugged in.

I agree. I'm kind of, outside the normal use case. I run several computer lab type things at my residence. My "main" home lab is all virtual, I have several systems doing virtual machines. I also normally have a physical lab set up around my workstation, including a lot of network equipment. So I tend to need more power than the average user.

I've heard, but I have no idea if this is correct, that idle consumption for PSUs is lower on higher supply voltage. Eg, the same PSU running a 60w computer load on a 120v supply will draw more relative amps than the same on a 240v supply. The numbers should scale to double the amps on the 120v, compared to the 240v, but apparently it's a bit more than that?

I dunno. Just something I heard. It's not why I'm thinking of doing it. Sometimes I just need to fire up a few kW of equipment to run some lab testing...

Homelabbers absolutely are a strange edgecase where a 240v circuit or two start making a ton of sense, but we're far from the norm. Heck the average American doesn't even own a desktop or laptop computer anymore, let alone the 1-2 dozen computers IT types and homelabbers might have on hand. It's all about perspective really...

Edit: Yikes that was a reading comprehension fail. You already said its an unusual usecase
