News Super Flower’s beastly 2800W power supply lands at $899 — enough juice to power a couple of RTX 5090 GPUs

The fire you could create with this PSU...
Yeah, I just looked up the specs of a nice air fryer and it uses only 1690 W!

This PSU is only surpassed by a full-sized electric oven. One example I saw runs on 240 V and uses up to 3200 W. Just to give you a rough idea of how much heat will be blasting from a PC which actually needs this amount of power!
 
That's a USA problem, most of the rest of the world has the home infrastructure to power this no problem.
I'm not an American, but ...

They do have 240V, that's whats supplied to their houses. In standard circuit boards the 240V is split into 2 120V circuits for domestic purposes. However, they are also designed in such a way that a 'special' 240V breaker can be installed that bridges the 2 120V back to a 240V circuit if they have need of 240V. Many people who have EVs do this for EV charging (if they don't want to pay to get some sort of fast-charging put in).

The US electrical system is not 120V

Yeah, my clothes dryer is the only thing in my home on a 240V circuit. If I wanted 240V anywhere else, I expect it would require running additional wiring & installing new outlets.

Interesting. I hadn't heard that.
 
Appliances can draw 3,000 watts from a standard UK wall socket, and in Western Europe that goes up to almost 3,700 watts. However, with heavy duty cabling you can get 7,000 watts of juice to your UK PSU. After that we are talking 400 volt three phase, which you will have to share with your Tesla charger.

I'm looking forward to new innovations in PSU technology!
 
What do you plug this into if it's for a workstation? Even if you have a 20A circuit in the USA, that's 2400.
Typical 240 volt socket would be 30 amps in the US. These would be installed in any home where heating appliances were expected. A 120 volt socket converted to 240 volts would typically be 20 amps. .
 
Correct! Hence my use of the word "standard". And it's two hots(common), a neutral and a ground.
Yeah, I simply refer to the neutral as the ground since it's the necessary ground, similar to DC circuits.
The bare wire (safety ground) isn't required for operation. It's only there to provide a path to earth in the event of a short, to prevent electrical shock.

Not just in the US. 5A 220V is pretty common in some EU countries, especially in rural areas. 13A 220V is also very common though.
For the US, you'd need a 240V run. These are common in single family homes but are purposefully installed for specific appliances like ovens, dryers, water heaters, and air conditioners. It's rare to find an unused 240V plug.
 
The more I think about it, the dumber this power supply is.

Nobody is going to build a PC needing nearly 3kW, you'd melt for starters and even if you have AC - Can it take an additional 3kW of load in a single room?

Then there's the why, even if you could get your hands on 4x 5090s and managed to wire them up without burning your house down four times over, what are you going to do with them? SLI is dead so you can't use them for gaming so realistically we're talking rendering or AI.

But even those use cases don't make sense as realistically they would be rack mount machines with their own custom PSUs. Rack mount machines are designed to handle these sort of thermals and let's face if, if you need 4x GPUs in one machine you're probably going to have a lot more than one machine.

This PSU has approximately two real customers across the world.
