a 220 volt 20 amp circuit should be good for over 3500 watts constant load in North America. Why is it requiring two circuits?

Because most households in the US might have maybe 3 breakers setup this way, all of which are likely running critical infrastructure already. Most folks aren’t going to unplug their water heater to turn on their AI.

I assume the people dropping 15$k on one of these to have in their house are comfortable with paying an electrician to wire it in if necessary.

3200W seems perfect for a EU socket. Seperate breakers aren't really a thing here, at least in my country, usually if you need more power you draw 400V

No it doesn't. A standard EU Socket is not certified for 24/7 3.2kW. You should max. pull 2.7kW. For everything else you need a blue eu socket or camper socket. I learned this due to my EV which is able to be charged through a normal socket but it regulates it down due to this on purpose and has a temperature sensor build in as well.

Is it per spec, or from experience?

220V is American version of what is known as 380V/400V elsewhere.

US three-phase power is mostly 208V, 240V, and 480V. The 208V is what normal residential 120/240V split-phase was made from. 240V is high-leg delta three phase and I think was old alternative to split-phase. 480V is used for light industrial that needs more power. There is nothing in US power system that is 220V.

Ackshually, you need to tell that the GP of the thread, they began using "220v".

> All of the Seasonic power supplies that go beyond 1kW or so will trip my shitty (i.e. probably defective) Siemens AFCI breakers. Not even the same circuit all the time. I don’t know much about US electrical standards but aren’t your residential circuits rated for 1800w or 2400w? Here in New Zealand they are 2400w and people regularly plug in 2400w fan heaters without issue. > The HVAC solutions in most residences w…

> I don’t know much about US electrical standards but aren’t your residential circuits rated for 1800w or 2400w? The residential AFCI issue I describe isn't about the wattage directly. It's about transient currents generated by large switch-mode power supplies being detected as arc faults. Similar concern as with induction motors.

That is interesting. In New Zealand AFCI is only required on 20A sub circuits in places that have a high fire risk, contain irreplaceable items, school sleeping areas and some other minor circumstances.

Unless you're making money off it, $15k + however much you have to spend on installing a new breaker panel is too much to spend on hardware that will be outdated in 2 years. If you're making money off it, but you're still cheap, then buy a Supermicro + H100s and colo it in a datacenter. If you're not cheap, you'll just use Azure. So I'm not sure who this product is supposed to be for.

Motherboard and CPU, memory, NVMe drives, PSUs, SlimSAS cables and breakouts, a custom machined case, assembly, support. You're free to try building one yourself for cheaper. If you consider your time for researching/assembling/testing it to be worthless, and are happy with a contraption in a miner frame, then you can probably do it.

PC builds seem to short circuit everyone's pricing logic and drive any labor cost down to $0, just because they're willing to do it for free. Anything above that $0 is considered overpriced.

It’s not that they’re willing to do it for free. It’s that they’re doing it for fun. It’s a hobby, not work.

Part of the fun is planning, researching, putting together the pieces and power it on.

For that you'd probably be better off removing one of the GPUs, and replacing it with a networking card. The problem of the form factor will remain. The tinybox is 15U big for compute that you'd normally expect to find in a 4U form factor.

I don't think they're intended for rack usage like that. More like for people to put under their desks... there would be no reason to build the giant case with fancy silent-ish cooling if you're going to put them next to your other jet engines.
