Brand New Bitmain Antminer S21 Pro+The Antminer S21 Pro+ is designed for serious Bitcoin miners who need more power, greater efficiency, and enhanced durability. The S21 Pro takes everything you know about the S19 and S21 series and turns it up a notch.Compact Yet More Powerful DesignWhile the original Bitmain Antminer S21 was similar in size to the S19 series, the S21 Pro+ is significantly larger and sturdier. With a net weight of 44 lbs, about 30% heavier than the S21, this model incorporates a wider body, longer hashboards, and a redesigned control board layout. Its larger and thicker packaging foam ensures the unit arrives safe, though it may take a little extra effort to unbox.Optimized Cooling with Larger FansThe Antminer S21 Pro uses four 140mm high-performance fans (compared to 120mm fans in previous models) to improve airflow and heat dissipation. This setup reduces RPM stress on the fans, improves longevity, and creates more overclocking headroom.Next-Generation PerformanceNormal Mode: 237.2 TH/s at 3702W with an efficiency of 15.6 J/THLow Power Mode: 192.6 TH/s at 2842W with an efficiency of 14.7 J/THThanks to fewer but far more powerful chips (65 chips vs. 108 in the S21), each chip hashes at approximately 1.2 TH/s, doubling the single-chip hashrate of the S21. This allows the S21 Pro to deliver top-tier efficiency for large-scale mining farms or high-end home setups.Improved Control Board & HashboardsBitmain redesigned the control board to fit the S21 Pro’s wider chassis. The new board cover uses two screws for easier maintenance, though the front panel no longer includes an LCD display. Hashboards feature aluminum backing with bolt-on heatsinks and improved thermal compound for consistent cooling performance.Reliable Power SupplyThe APW17 PSU powers the Antminer S21 Pro, maintaining stability even under high loads. With its efficient power delivery, it complements the miner’s robust cooling to maximize uptime and profitability.Why Choose the Antminer S21 Pro+?Next-generation ASIC miner with exceptional performance and efficiencyLarger fans and improved airflow for cooler operationReinforced design and packaging for added durabilityLow Power Mode for reduced energy costs without sacrificing hashrateIdeal for serious Bitcoin miners and professional mining operationsConclusionWith superior chips, bigger fans, and a redesigned layout, the Antminer S21 Pro+ delivers a significant boost over the S21 and S19 series. Whether you’re expanding your mining farm or upgrading existing hardware, this model offers maximum profitability, stability, and efficiency.Comes with ~1 year manufacturer warranty.PSU included, APW17Note: Antminer S21 Pro runs on 220-277V voltage, it will not operate on household 110-120V voltageSpecificationsProduct Glance ModelS21 Pro+Algorithm | CryptocurrencySHA256 | BTC/BCHHashrate, TH/s234|245Power on wall @25°C, Watt3510Power efficiency on wall @25°C, J/TH15Detailed Characteristics Power supply Power supply AC input voltage, Volt(1-1)220~277Power supply AC input frequency range, Hz50~60Power supply AC input current, Amp20Adapted AC output power requirement, W4000Hardware Configuration Network connection modeRJ45 Ethernet 10/100MMiner size (length*width*height, w/o package),mm(2-1)450*219*293Miner size (length*width*height, with package),mm680*390*450Net weight, kg20Gross weight, kg22Noise@25℃，dBA76Environment requirements Operation temperature,°C-20~45Storage temperature,°C-20~70Operation humidity(non-condensing) , RH10%~90%Operation altitude, m≤2000
