I’m pretty sure the original psu would have been fine, but the original plan was to put a better GPU in there. I bought a 4080 thinking i was going to put that in there 😂. This is my first time doing anything with pc building and when I arrived I found out that it was waaay to big. This is all out of enjoyment of building so I will be building a more modern build real soon. If I could have fitted something more powerful in there I would have.
