Antminer S19K Pro C76 A113D Control Board | Brand-New Replacement Motherboard for S19K Pro Miner Repair
The Antminer S19K Pro C76 A113D control board is the brand-new replacement for the original S19K Pro motherboard. Drops in cleanly when the original board fails — common failure modes include a dead Ethernet PHY, a dead Amlogic SoC after a power-event, a corrupted EEPROM that no longer programs, or visible damage after a PSU fault that took the control board down with it.
This is the Ctrl C76 revision built around the Amlogic A113D main control chip. Identifiable by two 1*4p fan headers + two 2*2p headers — different from the S19j / S19j Pro / S19j Pro+ control boards, which use the same C76 generation but a different fan-header configuration. Match the existing board's fan headers exactly before ordering.
Fan Header Compatibility Notes
- Original fan connectors match the new control board headers — plug in directly, no adapter needed.
- Fan connectors are 1×4P — use two Antminer fan adapter cables to bridge to the 14P / 22P headers.
- Fan connectors are 2×2P — same workaround, two fan adapter cables for proper pairing.
- Always confirm the cabling before powering on — wrong-pin alignment will damage the fans, the control board, or both.

FAQ — S19K Pro C76 Control Board
Q: How do I know the control board is the failed part vs the hashboards or PSU?
A: Symptom triage: PSU outputs healthy 12V → confirms PSU. All three hashboards test green on a hashboard tester → confirms hashboards. Control board still won't respond on Ethernet or serial console → confirms control board. The C76 sometimes also shows visible burn marks on the Amlogic A113D after a power event.
Q: Will my existing firmware re-flash onto the new board?
A: Yes — the C76 A113D control board accepts the standard S19K Pro firmware image. After install, connect via Ethernet, run a fresh firmware flash through the web UI, or load via micro-USB serial recovery if Ethernet doesn't respond.
Q: My fan connectors are 1×4P — what do I order with the board?
A: Two Antminer fan adapter cables — 4P to the C76's 1*4P / 2*2P pinout. Standard accessory for S19K Pro maintenance. Match cable lengths to your chassis routing.
