On my configuration I also have a Gigabyte 2080ti oc gaming, and for cooling the new cpu I will use my Asus rog ryujin 360 aio. Thanks in advance for your help. I don`t plan to make a massive oc, if I could get 4,4-4,5 Ghz is perfect. My gpu isn`t overclocked at all and I don`t intend to do this.
So some quick and rough math.
TDP of 10980xe is 165 however with Turbo and OC you should stay under 2 x TDP so estimate at 330 Watts
Gigabyte 2080ti oc has a TDP of 300W, but shows a peak load of 352
CPU power pulled from https://wccftech.com/review/gigabyte...ard-review/10/
. Please verify I have the correct card as I consistently see RTX in what I found searching which you didn't list.
That has peak load around 682 before drives, fans and pump. That leaves about 168 watts to cover fans, pumps, drives, etc. Seems tight to me, but I am usually conservative on over sizing my power supplies. If you don't run workloads that fully load the CPU and GPU both at max at the same time and tune you OC to not get close to 2 x TDP you will probably be OK, but if both are consistently going to run at high loads it would worry me.
As a point of reference I run a 10920X at 5 GHz without HT and 3 x 150 TDP cards and when running FaH I average about 900 Watts with peaks in the mid to upper 900s (measured from PSU power output). That has 150 more TDP in video card than you will, but you will have 50% more cores and with HT enabled the power draw from the CPU will be higher.
I'm sure others will have opinions on this as well.
