In our previous article "Ethereum Mining Gains Popularity: How Should Beginners Get Started?", we introduced three entry methods for Ethereum GPU mining: cloud hashing power, joint mining, and purchasing mining rigs for colocation. While the first two options allow users to earn passively, the third suits experienced, large-scale miners due to the high maintenance demands of GPU rigs.
Today, we'll explore the essentials of GPU mining rig colocation, focusing on critical factors when selecting hosting facilities.
1. Safety and Reliability: The Non-Negotiable Priority
When hosting any mining equipment—whether Bitcoin ASICs or Ethereum GPUs—facility safety and operational integrity must come first.
Safety Considerations:
- Scientific Site Selection: Avoid facilities near dams or hydroelectric stations in flood-prone regions like Sichuan, where seasonal disasters frequently damage improperly located operations.
- Fire Prevention: Mining facilities crammed with electrical wiring risk transformer explosions, short circuits, or aging equipment failures. Last year, a Xinjiang-based facility burned down, destroying thousands of rigs.
Reliability Red Flags:
- Beware of "too-good-to-be-true" ads offering cheap electricity. Some operators engage in price gouging, abrupt closures, or even hash rate theft.
Pro Tips for Vetting Facilities:
- Opt for facilities recommended by trusted peers—personal connections reduce risks.
- Choose established facilities over new ones; experienced operators handle emergencies better.
- Prioritize large-scale, high-capacity facilities with strong market reputations.
- Prefer corporate contracts over individual agreements to ensure legal accountability.

2. Power Stability: A Critical Factor for GPU Rigs
Ethereum GPU rigs are notoriously sensitive. Frequent power outages damage components and prolong post-outage debugging compared to ASICs.
Key Insights:
- GPU rigs consume less power relative to earnings (10–20% electricity costs vs. 38% for Bitcoin ASICs), making them less price-sensitive.
- Example: A 5700XT 8-GPU rig at ¥0.38/kWh spends 16% of daily revenue on power, versus an S19 ASIC at 38% (¥0.23/kWh).
Recommendation: Prioritize grid-connected or thermal-powered facilities for stability over cheaper but erratic hydropower.
3. Specialized Maintenance Capabilities
GPU rigs demand advanced technical oversight:
- Complex Repairs: Standard ASIC technicians often lack GPU expertise, causing prolonged downtime during off-site repairs.
- Software Optimization: Choosing stable, low-fee mining software (e.g., optimizing for Claymore vs. Phoenix) impacts profitability.
4. Additional Facility Must-Haves
- Dedicated GPU Rack Space: Standard ASIC shelves won’t accommodate bulkier GPU setups.
- IDC-Grade Environmental Controls: Dust-proofing, anti-static measures, and precise humidity/temperature regulation.
- Accessibility: Proximity to transport hubs speeds up maintenance and inspections.
5. Conclusion
For most beginners, joint mining offers the best risk-reward ratio. Self-managed colocation suits only seasoned, large-scale miners.
Selection Checklist:
- Safety > Power Stability > Maintenance > Cost.
- Audit facilities for scalability, load capacity, and operational history.
- Favor corporate partners with transparent contracts.
FAQs
Q1: Why are GPU rigs more delicate than ASICs?
A: Their intricate hardware and software require stable power and expert debugging post-outage.
Q2: How much more space do GPU rigs need versus ASICs?
A: Typically 30–50% more, necessitating customized rack designs.
Q3: Can I use the same facility for both GPU and ASIC rigs?
A: Possible, but ensure the operator has GPU-specific maintenance protocols.
