In the used market, the Radeon RX 6600 XT fails to justify its value for money. It lags behind the Arc A750 which outperforms it by a lead of 28.3% in 3DMark benchmark.
Recommended PSU for the RX 6600 XT: about 600 W — the card draws 160 W, a CPU such as the AMD Ryzen 5 7600X about 105 W, and doubling the total leaves headroom for transient spikes. Pick a unit from a reputable tier of the Cultists Network PSU Tier List.
