Notes
•3x250W GPUs exceed HP's official 3x225W graphics envelope. Power-limited and thermally validated during burn-in
•PCIe 3.0 bandwidth ceiling visible during model load/offload, not during steady-state decode
•Pascal-generation FP16 performance. Compute-bound on small batch sizes
⚡Standard 120V outlet (1275W PSU). Power-limited GPUs draw ~225W each.
PCIe: Gen3-on-Gen3: no host-link mismatch for Pascal GPUs
