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.

  • Lock allocation in writing with firm delivery windows and cancellation terms
  • 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.
