I'm getting ready to assemble my new PC with a Ryzen 5 5600X and an RTX 3070. I'm considering a used power supply unit, and I'm wondering if I should stick with 80 Plus Gold certification, or if Bronze or Silver from a reputable brand like Corsair or Seasonic would be sufficient?

A 750W Bronze PSU should work just fine! I ran a similar setup with a 3070 Ti for about three years without any issues.

The certification levels like Bronze and Gold mainly measure efficiency, not necessarily the build quality of the PSU. You could take a look at the SPL PSU tier list online; aiming for Tier B or better is a solid choice for your setup.

FreshlySqueezed1: Oh right right! Thanks a lot man

PowerNerd99: It is a corresponding measurement of quality. That's what enables the higher efficiency.

While Bronze rated PSUs are acceptable, it's always a good idea to invest in quality components, especially for something as crucial as your PSU. Gold or Platinum rated units are more efficient and often have better quality parts.

Just a heads up: don't skimp on your PSU. It provides clean power to all your components, and having a cheap or underpowered PSU can lead to issues down the line. It's fine to go for a reputable brand like Corsair or EVGA, and having a little extra capacity can save you headaches later!

CraftyTurtle47: The thing is, Iโ€™m going with like a Corsair or EVGA because they are reputable brands. I did research and 650W is more than enough headroom. Itโ€™s just that I was worried about the bronze labeling.
