Time for a new pc. Will this suffice?

I would upgrade that power supply to at least 750 if not higher. 550 might struggle with just the 3060 ti, let alone paired with an Intel 12th gen CPU.
That’s a good spec. But as already mentioned, I’d upgrade the power supply if you’re ever going to do any more upgrades.
Looks pretty decent even though I would go with an RX 6700xt instead but that's just a personal preference (they are a close match). Also the case seems to have 6 120mm fan slots so you should fill these according to the ATX specification (front and botton inflow, top and rear outflow). The fans don't have to be fancy so just get something that works. With that, you will also need a SATA-powered fan splitter.
