Bought the Gigabyte Aero G Z790 mobo but not sure if some of the components am planning to buy go right
Heres the list
i5 13600k
Rtx 4070
Corsair iCUE 4000X case
750w psu(will it be enough?)
About power, what is the model of the PSU? 750W is enough, BUT low end power supplies do not deliver stated watts.
Also be aware that CPUs and GPUs can suddenly demand a lot of power, sometimes more than what is normally needed.
In your case, make sure you buy a good 750w PSU, or even a 800w model. Something like: be quiet! Pure Power 12 M 850 W 80+ Gold
The price difference between 750w and 850w models is very small.
