You should look at upgrading your PSU in the future, but for the GPU's you're looking at, its fine. I plugged your rough specs with an RX 6600 XT into a power supply calculator, with it on 24/7 and gaming at 100% CPU and GPU, its using around 420W at full load. Generally you want to keep 20% reserve on a power supply, so as long as its around 450W or so of continuous usage or below, it'll be fine (technically you can stretch it to 90% capacity with a good power supply, but 80% is recommended). None of the GPU's you asked about will cause any issues with your current setup. Also, throw the RTX 3050 off your list. The RTX 3050 was a crappy GPU to begin with, and it hasn't gotten any better. RTX 3060 is typically over priced for what you get vs an RX 6600 XT or RX 7600, yes the ray tracing performance is better, but in anything that isnt ray traced (most things) its slower than both. Also, none of those cards have very good ray tracing performance. I've included a review for the RX 7700 XT since it has most of the cards we talked about in it, except for the vanilla RTX 4060. So I've also attached an RTX 4060 review for reference, it performs about the same as the RX 7600. Technically you could run up to an RX 6700 XT or RTX 4070, but it would be a very good idea to upgrade your PSU beforehand.
