I don't think pulling wire is that likely, at least probably not with recent construction in a place with code enforcement. Standard here would be a 120v 20 amp circuit on 12 gauge romex... I'm not an electrical engineer, but shouldn't that be sufficient for nearly 2000 watts constant load? I've done a little bit of homeowner construction to code, and they make you run a separate circuit for just about damn near everything these days, except lights... I guess the concern would be if you've got an old 15 amp circuit on skinny little wire or hooked up to your air conditioner....

120V, 20A circuit is solid for 1920W continual, 2400W peak. Most household outlets, branches, and breakers are 15A though and that means 14 AWG. Might be better in newer construction but wire is expensive and builders are usually cheap.

If someone is looking to do an upgrade just do it right with 240V, 30A branch. An outlet like this is good for 5.76KW continual and ebay has tons of cheap used PDUs which have a NEMA L6-30 plug.

Probably good for at least 3 Sierras maybe 4 depending on what final wattage ends up being. My guess is HF puts some overhead in the PSU so 1700W of PSU doesn't mean they intend for it to draw 1700W. Drawing say 1300W would keep the PSU at 80% load.

Please don't burn your house down over this shit, people.
