Evaluating Supplier Quality: Key Criteria for Success

Selecting a supplier isn’t just about price—it's about total cost of ownership, reliability, and scalability. Below are essential factors every procurement manager should assess:

Technical Performance and Component Quality

Prioritize suppliers whose machines deliver strong hash rates (e.g., 110 MH/s or higher) combined with low power consumption (ideally under 0.02 J/MH). Examine the source and quality of ASIC chips, motherboards, and cooling systems. Machines built with industrial-grade components typically last longer under continuous operation and require fewer repairs.

Certifications and Compliance

Look for suppliers holding internationally recognized certifications:

• CE: Indicates conformity with European health, safety, and environmental protection standards.
• FCC: Ensures electromagnetic compatibility and safe radio frequency emissions.
• RoHS: Confirms compliance with hazardous substance restrictions.
