Key Features of the Bitmain Antminer KS5 (20Th)
The Antminer KS5 is engineered for stability and efficiency, combining optimized power consumption with robust processing power. Here are the core features that set it apart:
- Hash Rate: 20 TH/s ±5%, ensuring consistent mining output across various SHA-256 based cryptocurrencies like Bitcoin (BTC) and Bitcoin Cash (BCH).
- Power Consumption: Approximately 1850W at 220V, delivering a competitive efficiency rate of ~92.5 J/TH.
- Cooling System: Equipped with dual high-speed fans for effective heat dissipation, maintaining optimal operating temperatures even under continuous load.
- Noise Level: Operates at around 75 dB, which is standard for industrial-grade miners—best suited for dedicated mining facilities rather than residential setups.
- Dimensions & Weight: Compact design measuring 185 x 290 x 365 mm and weighing approximately 7.5 kg, allowing for efficient stacking and space utilization in large-scale deployments.
These technical attributes make the KS5 ideal for professional miners focused on maximizing uptime and minimizing operational costs.
Pricing Structure and Model Variants
The Bitmain Antminer KS5 is available in two configurations: KS5 Pro and KS5 Std. While both models offer the same hash rate and energy efficiency, they differ slightly in internal components and pricing per unit.
- KS5 Std: Base model, priced at $1,980.00
- KS5 Pro: Enhanced build quality and component selection, priced at $2,980.00
It’s important to note that:
- Both variants share the same per-terahash value, meaning cost-effectiveness remains consistent across models.
- Orders may be fulfilled with either model or a combination of both, depending on stock availability.
- Final invoicing will reflect the actual units shipped.
This flexible fulfillment approach ensures faster delivery times without compromising on performance metrics.
Shipping, Import Duties, and Customs Compliance
All Antminer KS5 units are manufactured in China. International buyers—especially those in the United States—should be aware of additional import considerations:
- U.S. Tariffs: A 25% tariff applies to shipments entering the U.S., which is not included in the listed retail price.
- Customs Responsibility: Buyers are fully responsible for providing accurate documentation and complying with local import regulations. Delays or rejections due to incomplete paperwork are not covered by the seller.
- Shipping Priority: Orders are processed on a first-paid, first-served basis. Full payment must be received before shipment scheduling begins.
To assist with customs clearance, Bitmain provides official certification documents through their support portal. These include compliance certificates and product specifications required by many international customs agencies.
