The first salvo of RTX 50 series GPU will arrive in January, with pricing starting at $549 for the RTX 5070 and topping out at an eye-watering $1,999 for the flagship RTX 5090. In between those are the $749 RTX 5070 Ti and $999 RTX 5080. Laptop variants of the desktop GPUs will follow in March, with pricing there starting at $1,299 for 5070-equipped PCs.
1000W PSU pulls max 8.3A on a 120v circuit.
Residential circuits in USA are 15-20A, very rarely are they 10 but I’ve seen some super old ones or split 20A breakers in the wild.
A single duplex outlet must be rated to the same amperage as the breaker in order to be code, so with a 5090 PC you’re around half capacity of what you’d normally find, worst case. Nice big monitors take about an amp each, and other peripherals are negligible.
You could easily pop a breaker if you’ve got a bunch of other stuff on the same circuit, but that’s true for anything.
I think the power draw on a 5090 is crazy, crazy high don’t get me wrong, but let’s be reasonable here - electricity costs yes, but we’re not getting close to the limits of a circuit/receptacle (yet).
Actually the National Electric Code (NEC) limits loads for 15 Aac receptacles to 12 Aac, and for 20 Aac receptacles 16 Aac iirc because those are the breaker ratings and you size those at 125% of the load (conversely, 1/125% = 80% where loads should be 80% of the break ratings).
So with a 15 Aac outlet and a 1000 Wac load at minimum 95% power factor, you’re drawing 8.8 Aac which is ~73% of the capacity of the outlet (8.8/12). For a 20 Aac outlet, 8.8 Aac is ~55%% capacity (8.8/16).
Nonetheless, you’re totally right. We’re not approaching the limit of the technology unlike electric car chargers.
That’s just the GPU with efficient other parts. Now if we do 575W GPU + 350W CPU + 75W RGB fans + 200W monitors + 20% buffer, we are at 1440W, or 12A. Now we’re close to popping a breaker.
This makes me curious: What is the cheapest way to get a breaker that can handle more power? It seems like all the ways I can think of would be many 5090s in cost.
How many RGB fans does this theoretical build have to use 75W alone?
How else are you gonna cool 925W in a PC form factor? Ever seen fans for server racks?
hire an electrician (or dependent on local laws DIY) to add a dedicated 240v 20a outlet with 12/2 wire.
Out of curiosity, how much does this cost with an electrician?
