Alright old ass pensioner, don't get me wrong, I'm not saying it's a good or it's the best option, but 450W is literally enough for a ryzen 2600 and the gpu which was stated, and no, it will not blow up if it's bronze or higher grade.
Don't act like you're sick at PC builds when you don't know enough about it.
You say you've been building PCs since 07, what as a hobby? I did it as a side job.
Iv built many budget build or builds where for some reason the customer wanted certain, questionable, combinations.
450W with the other compenets would sustain for, most likely, 3 years give or take a few months.
I stated that in the long run it's worth getting more, I also said I recommend 600W at the least.
So read properly, understand the situation, and shut the fuck up you amature.
