Overclocked or unlocked power limits

Power figures are estimates of sustained DC load from typical part specs. Balance uses relative gaming indexes (Ryzen 7 9800X3D = 100 for CPUs, RTX 5090 = 100 for GPUs) in GPU-heavy titles; esports games lean harder on the CPU. Use it to plan builds and explain choices, then verify with real benchmarks.
