Question Wattage need

[machadinhos]

Hi everyone!

I'm currently building a new PC and I'm not sure of what PSU wattage I should get...

PCPARTPICKER says that the estimated wattage is 664w. Should I get a 750w or a 850w PSU?

This is my current list of components in case you want to know:

GPU	Gigabyte WINDFORCE OC GeForce RTX 4070 Ti 12 GB
CPU	Intel Core i7-13700K
CPU Cooler	Cooler Master MasterLiquid ML360 Illusion
Motherboard	MSI B760 GAMING PLUS WIFI ATX LGA1700
Memory	Lexar Ares RGB 32 GB (2 x 16 GB) DDR5-6400 CL32
Storage	Samsung 990 Pro 1TB
Power Supply	Gigabyte UD750GM 750 W 80+ Gold Full Modular
Case	Lian Li Lancool III RGB

Thanks for the help! You guys are awesome!

i'm looking at about 275-300w for the gpu gaming. about 200-250w for the cpu gaming. throw in another 100w for the mobo usage and that 664w guess from partpicker isn't too far off.

all depends on if you're overclocking/removing power limits and trying to push it to the max or not.

either way the 850w psu looks like a better option, just to leave some headroom. that's the way i'd go to keep it from having to run too hard all the time.
