PSU is likely not the greatest, certainly a lower end EVGA 500w model with a 3 year or so warranty. Nothing inherently wrong with B550 for any build and the 5600X is a good gaming chip. 3060Ti is strong. Case looks like it doesnt have much ventilation so its going to get warm, which also effects longevity. The headline parts are good, but the case, power and storage are below average. Overall its not terrible.
Alternately you can build something stronger and more durable for about the same money yourself with a little research.

This one has a top quality case and PSU and much faster and more storage, not to mention a higher tier GPU. The CPU is negligibly slower but 50 cheaper. Also better, quieter CPU cooler, and decent motherboard..
Intel build with a 12400F or 12600K may be a little cheaper and perform around the same, if youre interested I'm sure I can look into it when I have time or someone else will
