News New RTX 4090 Cards Can Access Up to 1200W of Power

[Admin]

Galax has announced two brand new RTX 4090 Hall of Fame video cards, aimed at extreme overclockers. The biggest star of the show is the card's power twin 16-pin power connectors which can bring in a total of 1200W of power consumption.

whats a max power draw a PSU can have?

When will Nvidia have to find another way to go fast?

 

[kal326]

Oh joy, twice the potentially improperly seated or made cable fire risk.

 

[Colif]

Nvidia should just integrate the PSU into the GPU, that would remove need for the cables and would reduce risk of a poor PSU being asked to run it.

 

[Math Geek]

cause 600w worked out so well so far.

whats a max power draw a PSU can have?

the limit would be the power socket it is connected to. most household circuits (in the US anyway) are 20 amps. at 115v that is ~2300w. that of course assumes the pc is the only thing on the circuit which is unlikely. at the rate nvidia and intel are going, people are going to need dedicated circuits just for their pc.....

They need their own generators, and a fuel source.

think i read a post recently where someone has to move his pc out of bedroom as its overloading the circuit. And that is without one of these or future cards... 5090 will use 4 12 pins (note: this isn't real)

Thats a good heater for winter!

PSU makers might need to start using "welding cable" to power these Nvidia graphics cards.

Actually, household circuits have a continuous load rating only 80% of nominal circuit rating. So for a 20A circuit, the maximum continuous load is 16A, which works out to 1920W at 120V. The extra 4A is to allow things like being able to toast stuff while the kettle is also on - the circuit can bear the mild overload for the 2-3-min it takes for toasts to pop and the electric kettle to shut off, then wiring typically has plenty of time to cool of before the next mild-overload use.

 

[Math Geek]

should not be too much longer and i expect we'll start seeing "intel rated psu" vs "amd rated psu" or "this one can actually run an nvidia card"

guess it'll add to the nvidia tax since folks already pay more for comparable performance vs an AMD card. may as well pay more for a psu that can actually run it.

thanks for the info. always nice to have all the facts. i was happy i knew the circuits were 20 amp at 115v

This card is for sub zero overclocking. Over 1000 watts has been the norm in this field for years. You would never need both cables plugged in for gaming.

Most US household circuits are 15A which max at 1800W's.

 

[Colif]

this card is, we are just predicting the future based on trends.

Finally, it's here...

This comment section is a riot lol even moderators join in

My fuse for the mains socket is 16A, at 240V it's 3840W of hypothetical draw before it trips. I wouldn't want to go near that for prolonged time. The wires are made of aluminium and old.
When changing a socket I learned one of the wires were broken inside the insulation. I had a problem with the fuse tripping occasinally without a reason and couldn't find the cause.
This makes me realize, latest top Intel CPU's and RTX's are not for everyone. With an old electric wiring you can burn the house down.

Well.... not all circuits are 20A. There was this thing with aluminum wiring... Some circuits are 10A.
Some are even 15A. Standards are not really standard, you know.

I think we've hit peak "stupid". 500W should be an absolute maximum safety/sanity limit for GPUs.
Even that is a bit ridiculous.

Most household circuits are 15a. 1725w. Kitchen and bath are 20a.

Lets focus the discussion on this card.

I don't really know the new flagships. is "Hall of Fame" the equivalent of the "lightning" series from MSI ?
I was the happy owner of 2x 290x Lightning in crossfire, watercooled and all. Beasts !

Oh joy, twice the potentially improperly seated or made cable fire risk.

In theory, it should halve the risk because now each wire should only need to carry half the current. In reality, this depends on how well the circuitry is set up.

Aluminum wiring comes with a much higher risk of fire. IIRC, it's because it heats up more than copper. I'm sure that it's less flexible and prone to cracking too. My house has aluminum 240V wiring, but someone disconnected it at both ends before I bought the house. At some point, I need to run it again for an electric car charger, but that'll need to go to 40A+.

But you don't hook up y our PC to 240V, you hook it up to 120V (or 115V), so halve what you calculated.

Good point. But a lot of homes are 15A, which really drops to 12A for prolonged usage...so lower than anything we've quoted.

None of this really matters of course--extreme overclocking bed should always have a dedicated circuit.

 

[Sleepy_Hollowed]

Oh no, no thanks. If this is the direction cards are going, I'm done with anything but mobile gaming.

 

[Deleted member 14196]

lol. I’ve been out of the gpu game for decades now because of this and stuff like this. Power and price are way out of whack

 

[FunSurfer]

Fire prone connectors with access to 666W of power consumption... They are just asking for it...
