Pre-purchase verification
What to verify before buying
At this price point, skipping due diligence is expensive. Every item below should have a documented answer before you wire funds.

- Verify liquid cooling infrastructure capacity: B300 requires direct liquid cooling
- Confirm power delivery: 20+ kW per node requires significant PDU and UPS planning
- B300 secondary market does not yet exist; no resale liquidity if plans change
Export control notice
B300 carries the most advanced export controls in the NVIDIA lineup. Consult legal counsel before placing any allocation order with a non-US delivery address.
