Goldshell SC5 Pro (11 TH/s)

The Goldshell SC5 Pro (11TH) is an air-cooled ASIC miner for the Blake2b-Sia algorithm, released in January 2024. It delivers 11 TH/s at 2820 W, which works out to about 256 J/TH. That puts it in the lower half of the Blake2b-Sia field: less efficient than the Goldshell SC6 SE (about 194 J/TH) and its successor the SC5 Pro 2 (about 236 J/TH), but more efficient than the iBeLink BM-S1 (about 346 J/TH). The machine mines Siacoin (SC) and BTCB2, the Bitcoin fork that moved to Blake2b-Sia, and MinerCompare calculates the result with whichever of the two pays more at your electricity rate. A second mode is listed at 8.8 TH/s and 2020 W (about 229 J/TH), so the machine can be run slower to trade hashrate for lower consumption. At nearly 3 kW the SC5 Pro is a serious mains-powered unit for a gara…ge, workshop or dedicated mining space with cheap electricity, not for a desk. Because its efficiency is average for the class, the outcome depends strongly on your price per kWh, so enter your own rate in the calculator.

The SC5 Pro measures 370 x 305 x 450 mm and weighs 13.1 kg, so it is a shelf or floor machine that needs a stable surface with free space around the air intake and exhaust. Noise is listed at 55 dB, with two fans moving air through the case. That is clearly audible and rules out a bedroom or living room. The listed supply is 220 V and the draw is 2820 W, so the circuit, plug and cabling must be rated for the load, and the line should not be shared with other heavy consumers. The connection is Ethernet only, so the miner needs a cable to your router and is then configured over the network with the address and worker name of a Blake2b-Sia pool. The specified operating range is 5 to 35 °C at 10 to 65 % humidity, so keep the intake air cool and dry and lead the exhaust heat out of the room. Wi…thin the Goldshell range it sits between the 4.4 TH/s SC Lite and the 14 TH/s SC5 Pro 2, the same class with a higher hashrate and better efficiency, which makes the SC5 Pro mainly interesting at a low electricity price or as a used machine.
