NVIDIA NVL576 TCO Shift & 1MW Rack Debate

NVL576 rack-level system redefines TCO; air-cooled busbars limited to ~150-160 kW; liquid-cooled power distribution necessary. Multi-channel design claims 20% improvement. 1MW rack debate challenges extreme density assumptions. Rental rate $5.45/GPU-hr. Power Integrations' 2200V GaN enables 1500V distribution. Trane Technologies and Eaton collaborate on reference design aligned with NVIDIA DSX, claiming 15% efficiency gain, 80% copper reduction, 30% cost cut.
