ATX 3.0 Power Supplies 1 story

Within PC Power Cooling & Cases, ATX 3.0 Power Supplies deserves its own scope because its behavior, configuration, and compatibility questions are distinct from the surrounding topics. The semantic core includes aTX 3.0 specification, PCIe 5.0 power delivery, GPU transient loads, and modern PSU standard, which together define the functions, interfaces, and operating behavior that make this topic different from adjacent components. This keeps the tag narrower than PC Power Cooling & Cases as a whole while giving readers enough context to evaluate compatibility, configure the feature correctly, and recognize when a separate problem-specific tag applies.
