I certainly won't buy a 900W card but i don't see how it's an issue for residential power. A single socket can deliver 3520W here, even with the whole computer and screens you will still have no issue. You may eventually need a higher subscription than the medium 6kva i have if you intend to cook and heat at the same time that you are playing but that's pretty much it. I don't think that the kind of people who would be interested in this card would mind the price difference.
In europe maybe, but in North America, house hold socket are on 120v and have a maximum rating most of the time of 1800w for a 15 amp circuit. Note that it's not every single socket that can deliver either 3500w or 1800w, it's each circuit. Depending on how your house is wired, you can have multiples thing on the same circuit. It's not common to have multiple house socket on the same circuit. It's even worst for older houses.
So let say you have a 900w GPU, a 170w+ CPU(i doubt you would run that card on a low end cpu), plus 30w for the rest of the system, you are at 1100w. PowerSupply aren't 100% efficient so you can add another 100w of loss on top of that. Then you have monitor. some can easily use more than 50w per monitor. if you have more than 1, you can start to get closer to the circuit breaker.
And you haven't plug anything else. Normally, for kitchen, they design it so that each socket have it's own circuit, if that trend continue, we might have to design home office to get the same treatment.
But before we get there, we need to consider how much heat those kitchen appliance output. I mean, that PC would have more heat output than the heating system of the room i would put it in.
I wonder if Ferrari considered that consumers have to pay for gasoline. I could not justify paying for an additional 10 gallons of gas.
I wonder if pool companies considered that consumers have to pay for water. I could not justify paying for an additional 100 gallons of service.
ece. ece. If the power draw of a GPU means your power bill will be a concern, you shouldnt be buying a likely $2500+ video card. compared to a 400w GPU like the 3090 it's literally a 5-6$ difference over an entire YEAR unless you are playing 8+ hours a day, in which case your streaming will more then make up the difference.
it all depend where you live.
let say you are not a hardcore gamer, but you still play 4 hours per day in average, a bit much on the weekend, a bit less during week, etc. Something normal for someone spending that much in equipment, if you live in an area where the electricity is around 0.20$ per KwH, it would cost you around 146$ per year more.
where i live, it still almost 60 buck. I mean it's not that much, but way more than 5-6 $ diff.
And it depend, some area have peek hour rate that are much higher, some have different tariff based on their consumption.
But still, my main concern would be that additional 500w of power that it would dump in my room. it would be the equivalent of having the other computer + this running at maximum power while I game:
