K9 ASIC Multifunctional Tester – Hashboard & PSU Diagnostic Tool

K9 ASIC Multifunctional Tester – Hashboard & PSU Diagnostic Tool for Miner Repair

Struggling to diagnose faulty hashboards across multiple miner brands? The K9 ASIC Multifunctional Tester is a professional ASIC hashboard tester and miner repair diagnostic tool built for crypto mining repair shops, field technicians, and farm operators. It replaces the need for separate test rigs by combining hashboard diagnostics and smart power supply testing in a single device — covering 70+ ASIC mining machines and 19 smart PSUs, including Antminer S21 and T21 power supplies.

Whether you run a multi-brand repair lab or manage a large mining farm with mixed hardware, the K9 tester helps you locate faults faster, reduce miner downtime, and streamline your entire diagnostic workflow.

Key Benefits

• Multi-brand support: Works with Antminer, Whatsminer, Innosilicon, Aixin, Cheetah, and Longteng miners — no need for separate testers per brand.
• Accurate hashboard diagnostics: Force plates provide a stable platform for reliable chip-level testing and fault detection on ASIC hash boards.
• Combined hashboard & PSU testing: Test miner hashboards and smart power supplies with one device — ideal for shops handling both component types.
• EEPROM read & import: Read and import EEPROM configuration files to speed up repairs and avoid manual reconfiguration.
• Faster fault detection: Helps technicians identify defective chips, voltage issues, and PSU failures quickly — reducing turnaround time per repair.
