2 year old EVGA 650 GS ok to use with 1080 Ti? (not wattage, quality)

One GPU system, no overclocking planned. The PSU has spent the last two years with a 970, a little overclocked the last few months (if that matters for PSU longevity?).

 

I know the wattage is fine, but I also know the 650 GS isn't the ideal power supply in terms of quality (ripple suppression, and I think I read about it lacking certain kinds of protection?), and mine's not brand new either. I'm not used to having so expensive a component in my PC so I find myself over-researching and making myself nervous, perhaps unnecessarily. The 1080 Ti is being shipped so I could go pick up a more definitively top-quality unit while I'm waiting (in for a penny in for a pound, I guess), and the old one would still be a capable backup. Still, I don't want to replace a component unnecessarily. The 650 GS is "tier 2" according to this site, and I can read reviews and understand the theory behind things like ripple suppression so I see how it ends up there, but in practical terms is that something I should be concerned about? As I noted, the PSU has been under what I'd figure is pretty normal use. The only thing maybe worth noting is it spent the first 1.5 years plugged into a 3-prong outlet without an actual ground (bad apartment wiring!) but the computer ran fine the whole time. That's corrected.

650 GS is good enough, it's not bad enough to warrant upgrading, imo.

It's a good PSU, keep it.

Thanks, I'll hang onto it! That's what I figured but I'm good at making myself paranoid.
