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).
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.
350W CPU?? Even a 14900k is only 250W, most are 120-180.
75W of fans???
I’m sure you could find parts with that much draw, but that is not normal.
The 14900ks spiked over 400W in testing: https://www.anandtech.com/show/21378/intel-core-i9-14900ks-review-the-swan-song-of-raptor-lake-with-a-super-fast-6-2-ghz-turbo/3
Replace 50W of fans with 50W to the CPU.
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?
