You should consider moving up to 1kW due to high transient spikes of RTX 3000 cards. RTX 3080 will easily shoot up to, and over, 500W without any overclocking which can cause problems. See GamersNexus video on it here:
It's also worth considering a higher power unit for use further down the line considering how long you held onto your Corsair. We can only speculate on what future CPUs and GPUs will draw, but IMO the 'silicon wars' are fully underway with hot competition between Intel, AMD and Nvidia. They are pulling out the stops with products that draw more power than nearly anything that's ever been seen in the consumer space.
You can also check out Igor's Lab for transient spike information, but you'll need to translate to English.
One of the best places to go for PSU reviews is going to be Cybenetics Labs:
Cybenetics Labs – PSU Efficiency & Noise Level Certifications - Power Supplies
That's a link to their PSU review database which presently has 548 units in it. They verify 80+ certifications and also do extensive noise testing. You can look at PSU units by their verified 80+ cert, or by how quiet Cybenetics has determined the units to be. Each unit has an extensive report generated telling you, literally everything, about the PSU down to the types/model numbers of individual components that make up the PSU.
I just grabbed a Phanteks Amp 650W, a customized Seasonic design, for my HTPC due to their findings on how quiet it is even while under load.
