AI Infrastructure Cost Guide 2026 — GPU Cluster Costs, ROI, and Total Cost of Ownership
Private AI infrastructure is a significant capital expenditure — a single 8-GPU H100 SXM5 server costs more than most enterprise software licenses. Understanding the full cost structure — hardware, networking, storage, power, facilities, and operations — is essential for accurate budgeting and ROI analysis versus cloud GPU alternatives. This guide provides cost ranges for AI infrastructure components and configurations as of mid-2026, with analysis of total cost of ownership and cloud GPU cost comparison.
Note: AI hardware prices fluctuate with product cycles, supply availability, and currency movements. The figures below represent market ranges as of mid-2026. Contact Haink for current pricing on specific configurations.

Operating Costs (Annual)
Power Costs
Power is a significant ongoing cost for GPU infrastructure. An 8× H100 SXM5 server draws 10.2 kW at full load. At 70% average utilization: 7.14 kW effective draw. Annual power cost per server: 7.14 kW × 8,760 hours × USD 0.12/kWh (typical Hong Kong/Dubai colocation rate) = USD 7,500/year per server. For a 32-GPU (4-node) cluster: ~USD 30,000/year in power. For a 128-GPU cluster: ~USD 120,000/year.
Colocation Costs
Hong Kong colocation (high-density rack): USD 2,500–5,000/rack/month for 20–40 kW. A 4-node H100 cluster occupies 2–3 racks: approximately USD 5,000–15,000/month. Dubai free zone colocation: similar pricing, USD 2,500–5,000/rack/month. Annual colocation for a 4-node cluster: USD 60,000–180,000/year.
Support and Maintenance
- NVIDIA DGX Care (DGX systems): USD 30,000–60,000/year per DGX node
- Dell ProSupport Plus (Dell XE9680): 5–8% of hardware cost annually
- HPE Pointnext Tech Care (HPE Cray XD670): 4–8% annually
- Supermicro SMCI warranty extensions: USD 5,000–15,000/year per server
Total Cost of Ownership: 3-Year Example
3-year TCO for a 4-node × 8 H100 SXM5 cluster (32 GPUs) in Hong Kong colocation:
- Hardware (servers + network + storage): USD 1,950,000
- Colocation 3 years (2 racks × USD 3,500/month × 36): USD 252,000
- Power 3 years: USD 90,000
- Support contracts 3 years: USD 120,000
- 3-year total: approximately USD 2,412,000
- Cost per GPU-hour at 70% utilization: approximately USD 3.80
Equivalent AWS P5 reserved (H100, 1-year commitment): USD 14/GPU-hour. Equivalent AWS P5 on-demand: USD 32/GPU-hour. Private infrastructure is approximately 3.7× cheaper than AWS reserved and 8.4× cheaper than on-demand over 3 years at this utilization level.
