Context Before
Source: Nvidia VR NVL72 Component BoM and Power Budget Model ↗
Evidence
Since the VR NVL72 rack busbar is still running at 50V and the compute tray can only take in 50V, the 800VDC from the power rack cannot be directly delivered to the busbar
Context After
② Atomic Claim
由於 VR NVL72 rack busbar 仍運作於 50V，且 compute tray 只能接收 50V，因此 power rack 的 800VDC 無法直接送進 busbar。
