Explanation

Wattage is the most critical PSU specification to verify. A high-end GPU alone can draw 200–350W under load. Combined with the CPU and fans, an underpowered PSU will cause instability, random shutdowns, or prevent the system from booting. Chassis ventilation (B) is important but independent of PSU selection. Motherboard firmware (C) doesn't affect PSU compatibility. Cable color coding (D) is standardized and not a meaningful compatibility concern.
