2000+ watt power supplies?

[SimicEngineer]

Apparently these have been around (or at least announced) for a couple years, but I'm just starting to notice listings for power supplies rated at 2000+ watts. Normally I'd assume these are exaggerated ratings from sketchy vendors, but I see models from SilverStone, Cooler Master, and FSP. These ratings only apply when the input is 220-240V, which makes sense considering that a typical North American circuit can only deliver 1800W. Is the expectation that these only get used in countries where 220-240V is the norm, or are we supposed to start running NEMA 6-15R outlets like for high-power welders and air conditioners? The power cords for that connection are sold, but I'm not sure what they're actually meant for (e.g. Monoprice 6-15P to C13[www.monoprice.com]).

that's not entirely true , the voltage in Europe is indeed 220-240 but the load amperage on outlets is actually less the half compared to the US , most European outlets are rated for 5-6 amps at 220-240 VS the us where they are rated 15 amps at 110v.

I doubt it's most EU countries.

Denmark has their outlets rated for max 10 - 13 A.

Max in UK is 13 Amp

… North American circuits only deliver 1800w? That can’t be true!

You are correct: 2000 watt power supplies do exist but they can not be used in the USA. This is why typically they are only marketed in parts of the world where 240vAC is standard.

Most NA households are designed with a 15 amp limit per circuit and 15 amps @ 120vAC, single-phase = 1800 watts.

Wow… i assumed it would be close to 30amps or something. So things like kettles, jet washes, fan heaters, toasters etc max out at 1800w. It must take forever to make a cup of tea!

Actually the things you are referring to (dish washers, toasters for bread, kettles, etc) take roughly the same time to complete their task as they do in the UK when in the USA. They are just designed for different power systems. Things don't take longer to function here running with the 1800W limit. We just have to be careful how many of those devices that we use on the same circuit at the same time.

Like in our kitchen: The microwave has to be on a different circuit than the electric skillet if we want to use both at the same time.

In Bulgaria, our outlets should be able to handle up to 16A

Oh yeah, I think ovens, washing machines, hoovers etc are all approx 1kw. My toaster is 1800w but the biggy is the kettle… 3kw. Heating water will anlways be quicker with more watts. And the shower (7.5-10.8kw usually) but they go straight to the mcb.

Most PSUs that are 1600W or higher, and certainly over 1800W, will not be using a C13/C14 connection. They will be using a C19/C20 connection as that wattage will exceed the rating for the C13 plug. You might find some with a C15/C16 which is like a C13/C14 but keyed with a notch/key and is rated for higher power and higher thermal load on the cable insulation; however more likely you’ll find them with C19/C20.

europe is a continent not a country.

in my country the netherlands.. we have 230volt.. and one group can deliver upto 16ampere
as a general rule exceding 3500 watt on one group is not advised.
(they can ofcourse handle 3680w, but no output is stable.. there always is a "wave" of higher, lower draw.. and if any peak reaches over 3680w.. the plug plops out.

(luckly all houses now have switches instead of fusical plugs... so it's easy to turn them back on)

most households have 2 or 3 groups,
so that gives a max use of 7000 or 10500 watt for an entire household..

plenty of room for a pc of 2000 watt.. provided you not put all your heavy appliances on the same group and turn them all on at the same time.


but with the COST of energy... such insane powerdraws for modern gpu's.. are why people like me postpone upgrading.. I rather spend 3000 euro for a 4090 that uses 250W.. than the current price with it's insane 450W...

at least in the past we also did have 1500-1600w psu's but we could 4 way SLI.. and that we could easely disable... and only turn it on when it was needed.. with just ONE gpu using such insane amounts.. well crap...

Individual socket outlets in the UK are rated at 13A, so they can happily go up to over 3KW.

yea 15a is a normal outlet/breaker at 120v = 1800w
a few use 20a, kinda uncommon for 120v*20a = 2400w
but in those cases, thats the limit for the outlet circuit
often rooms or zone of house will all be on the same breaker, lights and outlets should be on separate breakers

and maybe 1-2 outlets use both rails 240v for electric stove or dryer at 20-30a for upto 4800-7200w

From what I know electric kettles are indeed slower in US comparing to 3000w kettles in Europe. Of course there will no difference on weaker kettles at 2000w or below.
