[SOLVED] PSU for 3900xt and rtx 3080

[TheRickert]

So im currently upgrading and bought a 3900xt.
I already have a 750w gold + power supply, however i dont understand wheter it will be enough

I will be using

• ryzen 9 3900xt
• atx motherboard
• rtx 3080
• dark rock pro 4 cooler
• 5 case fans
• 2 m.2 nvme ssd's

(monitor, keyboard and mouse ofcourse)

Is a 750w power supply sufficient for this?
Since i cannot quite understand if the 105tdp of the 3900xt is the max wattage or what it means (since i have seen reviews where it draw 200w)

Thanks in advance!

750 should work just fine

Okay thanks! but can you maybe explain to me how this works? like i know what TDP means. But is tdp also related to psu wattage or is that determined by the actual watts the processor draws? Could you maybe elaborate on it

Any more recommendations?

the tdp wattage is basically the wattage used by the cpu.
