Questions
How much power does a GB300 NVL72 rack use?
About 132–140 kW per rack in normal operation, with higher peaks. It is fully liquid-cooled; there is no air-cooled version.
GB300 NVL72 or 8-GPU B300 servers?
NVL72 joins 72 GPUs in one NVLink domain, which matters for the largest models. For most workloads, 8-GPU B300 servers are simpler to buy, host and scale.
How long does an NVL72 take to deliver?
Rack-scale systems are allocation-led and take longer than 8-GPU servers. See current status on our supply desk.
