The PSU came with my computer a couple years ago, and I never upgraded it, but I mean it still works fine so. It is a HEC-600TC-5WK
The ram is 2400mhz, I guess I would need a new mobo if I were to get a 10th gen/AMD chip. What do you recommend?
That’s a very low quality psu, I would not risk a new system on it. It’s inadequate for a gaming system and puts the system at risk of damage. I would not be surprised if you had instability issues trying to run that gpu.
Your RAM is very slow, for this reason I would look at 10th gen Intel. It will be less impacted by the slow RAM.
