How is a computer going to pull 2400W? Unless you are installing a 220V plug for it. I think 1500W is the max appliance wattage you can sell in the US. And nearly all houses are built with 15-amp plugs and circuits which would be a max of 1,800 watts.

In general though, I would support a maximum wattage on computers. I also support minimum efficiency standards.

Basically the ATX 3.0 specification states:
1) A PCI 5.0 component can use up to 600 W continuously
2) A PCI 5.0 component is allowed to spike up to 3x power for up to 100 microseconds.

ATX 3.0 explained: Why Intel gave power supplies their first overhaul in 20 years

Intel talks all things ATX 3.0, PCIe 5.0 GPU connectors, and why you might need a new PSU.
www.pcworld.com www.pcworld.com
Then add in your CPU and other component's power consumption (like a few hundred watts maximum).

Combine those #1 and #2 and a GPU could theoretically use up to 1800 W for 100 microseconds. 100 microseconds isn't enough to trip typical circuit breakers.

Good info, @dullard , thanks. But you forgot to mention the enthusiast cards with TWO 16-pin connectors, thus double your estimations.

Even then, using 1200 W continuously plus ~300 W for the rest of your system (~1500 W total) shouldn't trip a 15 A circuit breaker (1800 W). The current/time curve will vary from breaker to breaker. But, a typical 15 A home breaker will trip between ~10 seconds and ~100 seconds with a 30 A current. That means even if both PCI 5.0 connections used 3x power at the exact same time you'd still likely be able to run no problem with a typical 15 A breaker. That is because the excursion is only for 100 microseconds at max. And just because they CAN have that peak does not mean that any designed components WILL peak at 3x the rated power.

Although if I were to use a system like that, I'd just run a 20 A line or a 220 V line just in case.

You're going to see future ATX 3.0-compatible PSUs (with dual 16-pin PCI-E 5.0 connectors on them) that only run on 220V, for the higher-end enthusiast.

Might as well take the time to call an electrician out to install a 220v circuit in your "PC Room", if you are currently a high-end gamer.

Miners were the first to do this, but the gamers will follow suite soon enough.

if you have a Tesla, you probably already have 220v plug installed.

Yeah, that makes sense. When @rstrohkirch pointed out that it was "transient" I figured it must be around 100 ms max, but that isn't really what anyone would consider "2400W," it'd be like claiming a 1HP was actually a 3HP motor because of in rush.

Most of your appliances are 30-amp. An 1800W UPS is 20 amp.

Yeah, citation needed.

Electric code in the US is 120V, single phase, with a 15-amp breaker. A few jurisdictions require 20-amp circuits, but still only require 15-amp plugs. Very few home have 30-amp, 120V circuits.

ETA, some appliances companies do have BS marketing using in-rush current and other BS specs, though.

Basically they are allowing 401k buying.

How many of those people are going to look at the recent Bitcoin price chart and think "Gee, that's a good place to put my retirement money", though?

I'd imagine that most corporate 401k's wouldn't even allow it, for the same reason they don't allow funds that short stocks. It's a too risky investment for retirement.

NEMA 5-20P is not common in the typical North American house at all. Typical circuit is 120VAC 15A, that is the code.

VA by Input Type2,200 (2.2 kVA) at 120, 125 V input
2200 VA / 120 V = 18.33 A
2200 VA / 125 V = 17.6 A
Technically, this does not pull 20 A. ;)

I think you missed the actual voltage that you replied to "from a 110VAC socket". Why would you then post 125 V comments? Finally, that is a business UPS where many businesses have 20 A circuit breakers. Most US homes have 15 A circuit breakers. Both are a far cry from your "Most of your appliances are 30-amp" claim.

code says NEMA 5-20P has to be hooked up to 20A breaker. So not a typical 120VAC 15A circuit at all.

My mistake. I saw 1800W and assumed he was talking about 120V.
