Bitmain Antminer S21 XP+ Hyd. 480 Th/s Bitcoin Miner

Bitmain Antminer S21 XP+ Hyd. 480 Th/s Bitcoin Miner - genuine Bitmain hardware in stock at Bitcoin Mining Depot and shipped worldwide from our Causeway Bay, Hong Kong warehouse. Every unit is bench-powered, hashrate-verified against factory specification and thermally checked before it is packed, so the machine that arrives is exactly the machine you paid for.

Performance and specifications: the Bitmain Antminer S21 XP+ Hyd. runs the SHA-256 (Bitcoin) algorithm at 480 Th/s while drawing approximately 5280W at the wall, giving a rated efficiency of 11 J/Th. It is a hydro (water-cooled) machine and mines Bitcoin (BTC), Bitcoin Cash (BCH) and Bitcoin SV (BSV). Efficiency - joules per unit of hashrate - is the number that decides whether a miner survives a difficulty increase, so compare 11 J/Th against your electricity price before you commit capital.

Profitability and ROI: model it the honest way. Take daily revenue at current network difficulty, subtract (5280 / 1,000 x 24 x your kWh rate), then divide the delivered cost by that daily margin to get payback in days. Machines in this class stay comfortably cash-flow positive under roughly $0.06/kWh and need careful modelling above $0.10/kWh. Send us your power rate and we will return a written projection at no cost.

Power and site requirements: plan a dedicated 200-240 V circuit with 20% breaker headroom, because a standard 110 V residential outlet will not run this hardware. Hydro units need a prepared coolant loop, manifold and dry cooler, and reward you with far quieter operation and much better efficiency retention in warm ambient conditions.

Shipping, duty and payment: orders leave Hong Kong within 24-72 hours of cleared payment on express air freight with tracking, full customs documentation and double-boxed, foam-cradled packing with separately packed PSUs. We deliver to the USA, Canada, Europe, Australia and 100+ countries every week. Pay in Bitcoin, USDT and other major cryptocurrencies, or with CashApp, Chime and bank transfer, and duty and VAT are itemised up front.

Warranty and support: the Bitmain Antminer S21 XP+ Hyd. ships with written warranty terms and DOA protection, and our in-house Hong Kong repair centre services hashboards, PSUs and control boards for the life of the machine. Free remote setup support covers pool configuration, firmware and tuning. Ordering three units or more?
