In the used market, the Radeon RX 6600 fails to justify its value for money. It lags behind the GeForce RTX 3060 Ti which outperforms it by a lead of 44.0% in 3DMark benchmark.
Recommended PSU for the RX 6600: about 500 W — the card draws 132 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.
