GB300 NVL72 / Power and cooling
GB300 NVL72 power and cooling
A GB300 NVL72 needs far more power and cooling than a normal data center rack. That shapes where you can run it, and whether to buy or rent.
Power per rack
Introl, an infrastructure integrator, reports a GB300 NVL72 cabinet drawing about 120 kW, with peaks around 120.8 kW in mixed-precision training (Introl, Jun 2025). A typical enterprise colocation rack is designed for a small fraction of that.
Liquid cooling is required
NVIDIA describes GB300 NVL72 as a fully liquid-cooled, rack-scale system (NVIDIA). The hall needs direct-to-chip liquid cooling: coolant distribution units, facility water loops and the plumbing to every rack. Most existing data centers were built for air and can't host it without a retrofit.
What this means for buyers
- Renting from an operator that has already built liquid-cooled halls is the fastest route for most teams.
- Buying and colocating means finding a facility with liquid cooling and high-density power positions available on your timeline. These are scarce.
- Building means a new or retrofitted hall, with power and cooling equipment lead times on top of the GPU lead time.
