By:GlobalOEMsWhat This Board Is
For Antminer S19Kpro operators, the control board is the nervous system of the hashboard chain. When it fails, entire mining rigs sit idle. Stellapex Modular Tech’s OEM control board, manufactured by Bitmain, is a direct replacement part that keeps S19Kpro units producing.
The board is listed at US$225 per unit. Buyers can select either stock or used condition, with a one-year warranty included. Material is metal, and the unit is rated above 1000W, which aligns with the S19Kpro’s power draw.
Key Specs to Check Before Buying
Spec sheets for aftermarket mining parts often hide more than they reveal. For this board, the listed attributes narrow down to a handful of practical points worth verifying.
- Rated power:>1000W, matching the Antminer S19Kpro’s operating envelope.
- Material:metal construction, typical for high-heat mining environments.
- Warranty:one year from Stellapex Modular Tech.
- Condition:stock and used units are both available.
- Packaging:single unit in a color box; logo or graphic design can be added via digital printing.
Several other fields — algorithm, hashrate, memory clock, interface type — are listed as 'other' in the supplier data. Procurement teams should request the full datasheet before committing, especially for used units.
Who Makes It
Stellapex Modular Tech (Chengdu) Co., Ltd operates out of Sichuan, China, listing products across Bitcoin and Altcoin mining, mining farms, and related hardware. The company positions this board as an OEM part, with Bitmain listed as the manufacturer.
That OEM linkage matters when sourcing replacement control boards. For buyers who have already standardized on Antminer equipment, a board carrying the Bitmain manufacturer field reduces the risk of firmware or fitment mismatches.
Shipping and Logistics
Each control board ships as a single item in a color box. Place of origin is Sichuan, China, which puts the supplier close to major mining hardware clusters but also means international buyers should clarify freight terms early.
No lead time is published. The practical next step is to ask for current stock availability, export documentation, and whether the seller handles logistics to your destination.
How to Order
Rather than clicking through a generic checkout, serious buyers will want to confirm the unit’s condition (stock vs. used) and request the serial number range or test logs if available. Then compare the $225 price against downtime losses from a failed S19Kpro.
For farms running multiple S19Kpro units, keeping one or two spare boards on the shelf is a direct hedge against a six-hour upload outage.
Note to Buyers
As with any used or stock replacement part, the listed specifications reflect supplier claims at upload. Verify warranty terms, especially for used units, and confirm return policies before placing a bulk order.
