AFRNDK Antminer S19 90T SHA-256 ASIC Miner

The AFRNDK Antminer S19 90T is a dedicated ASIC mining system built for the SHA-256 algorithm. It delivers a hashrate of 90 TH/s with a power efficiency of 36 J/TH. The unit connects via RJ45 Ethernet and operates at a noise level of 76 dB. It requires a 220 V input voltage to function correctly.

Suitable For High-Density SHA-256 Mining Operations

This miner suits operators running Bitcoin, BCH or BSV workloads who can provide 200–240 V AC power and tolerate 76 dB noise in a 0–40 °C environment. It is not suitable for standard 100 V residential outlets or quiet office settings. Buyers needing lower power draw or different algorithms should look elsewhere.

3250 W Power Draw At 25 °C Determines Infrastructure

The single specification that decides fit is the 3250 W wall power at 25 °C with a ±5 % tolerance. Your electrical circuit, PDU and cooling must sustain this continuous load plus the 47–63 Hz frequency range. If the available supply cannot meet 3250 W reliably, the miner will not operate as specified.

Questions about this item

How often do the four fans need cleaning or replacement on the S19 90T?

The four built-in fans run continuously at 76 dB; plan to clean dust from the intake every few months and replace any fan that develops bearing noise or vibration.

What thermal limit stops the S19 90T from hashing at 90 TH/s under sustained load?

The ASICs are rated for 0–40 °C ambient; if inlet air exceeds 40 °C the firmware throttles hashrate to protect the chips.

What is the steady-state power draw and noise level when the S19 90T runs 24/7?

At 25 °C the unit pulls 3250 ±5 % W from a 200–240 V supply and emits 76 dB from its four fans.
