Description
The Antminer Multifunctional Test Fixture is an essential diagnostic workstation for anyone serious about ASIC repair. Designed for permanent benchtop installation, this fixture tests hashboards, control boards, and power supplies across the full Bitmain Antminer SHA-256 lineup — from the S9 through the S19j Pro — without requiring a computer or external software.

Complete Hashboard Diagnostics Without Disassembly
The test fixture lets you check and determine whether a miner’s hashboards and PSU are faulty without disassembling the full machine. In maintenance mode, it accurately locates the root cause of hashboard failures down to the chip level, drastically improving repair efficiency and reducing turnaround time for your operation.
Self-Contained Operation
No control board required. No serial board required. The fixture runs its own self-contained test program with an integrated LED display, making it fully independent from any computer or external interface. Plug in a hashboard, and the fixture does the rest — delivering clear, actionable diagnostic results.
Full Bitmain Antminer Coverage
One fixture, two decades of Antminer hardware. Supported models span the T9/T9+, every S9 variant (S9, S9i, S9j, S9k, S9se, S9H), S11, S15/T15, the complete S17/T17 generation (including Pro, Plus, and E variants), and the S19 family (S19, S19 Pro, S19j, S19i, S19j Pro). Whether you are diagnosing boards from repurposed space heaters or testing hashboards from current-gen rigs, this fixture has you covered.
Built for Workshop Throughput
The benchtop design is optimized for repair shops and dedicated workspaces where multiple boards need testing in sequence. Its stable form factor and reliable connections mean you can process boards efficiently throughout the day without the fatigue and instability of handheld or improvised solutions.
What’s Included
- 1x Antminer Multifunctional Test Fixture (benchtop model)

Frequently Asked Questions
What is the difference between this and the portable version?
This benchtop model is designed for permanent workshop installation with a more stable form factor for high-throughput testing. The portable version is lighter and designed for field diagnostics. Both have the same testing capabilities and model support.
Can I test PSUs with this fixture too?
Yes. In addition to hashboard diagnostics, the fixture can independently test digital power supply units to verify they are delivering correct voltage and functioning properly.
How does the maintenance mode work?
Maintenance mode runs deeper diagnostics that can pinpoint the specific cause of a hashboard failure — such as a dead ASIC chip, broken trace, or voltage regulator issue. This precision allows targeted repairs instead of board-level replacement.
Is this fixture suitable for someone just starting ASIC repair?
Absolutely. The self-contained design and LED display make it accessible to beginners, while the maintenance mode provides the depth that experienced technicians need. It is one of the first tools we recommend for anyone building an ASIC repair workbench.
Why Buy from D-Central?
D-Central Technologies has been repairing Antminers since 2016 — this is the same fixture we use in our own Canadian repair workshop to diagnose thousands of hashboards. We do not just sell tools; we use them every day. When you buy from D-Central, you get the expertise of a team that knows ASIC repair inside and out. Every hash counts.
