How much life my PSU still have

I have 9 or 10 years old EVGA Supernova G2 650W. It was one of the best gold rated PSU's at it's time. Should I replace it on my next build or would it be ok for two-three years in my next build. I'll have a rx 7600 and 3700x/5700x. The next psu would be a mid tier unit while this is fully modular higher tier. If I end up replacing this, can you get semi modular PSU's on the budget.
