Context Before

For the VR NVL72 reference design, the power delivery infrastructure at the rack level includes four 110kW power shelves. The VR NVL72 system has a TDP up to 220kW for the 2300W Rubin TDP SKU. The design with four 110kW power shelves is an N+1 redundancy approach.

Evidence

Each 110kW power shelf is 3U tall

Context After

and includes six 18.3kW PSU with built in capacitors in the PSU. Each power shelf receives three phase 415VAC-480VAC of power from two 100A whips.

② Atomic Claim

每個 110kW power shelf 高度為 3U。
