Goldshell SC6-SE 17 TH/s Blake2B Siacoin Miner

17 TH/s on the Blake2B-Sia algorithm from 3,330W, both rated at about 5 percent tolerance, which is roughly 196 J/TH. That makes it the fastest and most efficient machine Goldshell builds for Blake2B, ahead of the SC5 Pro at about 256 J/TH, the SC Lite at about 216 and the SC-BOX II at about 211 in its default mode. Across the whole Blake2B field it places fourth on efficiency, behind the iBeLink BM-S3+ at about 136, the BM-S3 at about 163 and the SC-BOX II running in low power mode at about 179. Goldshell shipped it from September 2022.

185 to 285V AC on a 16 amp cable, and this is the single most distinctive thing about the machine. Every iBeLink Blake2B miner tops out at 240V and Goldshell's own smaller boxes run 100 to 240V, so at 285V the SC6-SE has the widest upper tolerance in the category by 45 volts. That has a concrete consequence on sites where single phase voltage runs high. The clearest case is the 277V leg of a US 480/277V commercial service, where this machine sits comfortably in specification and every iBeLink alternative is outside it, making the SC6-SE the only Blake2B miner of this class deployable there without a transformer. Note the flip side: it does not accept 100 to 120V service, so unlike Goldshell's boxes it is not a plug it in anywhere machine.

The BM-S3 is the stronger machine on the numbers and it is worth being direct about that. It produces 19 TH/s from 3,100W at about 163 J/TH, against this machine's 17 TH/s from 3,330W at about 196. So the iBeLink gives 12 percent more hashrate on 230W less electricity and roughly 17 percent better efficiency, beating the SC6-SE on every measure at once. If output and running cost are all that matter to you, buy the BM-S3. The SC6-SE wins in three situations: when your site voltage exceeds 240V and only its 185 to 285V range will do, when you already run Goldshell hardware and want one management interface and one set of spares, and when the BM-S3 is unavailable.

No. Goldshell states explicitly that this model has no low power mode, which is worth knowing because several other machines in the Blake2B range do. The SC-BOX II drops to 1.45 TH/s on 260W, the iBeLink BM-S1 to 4.3 TH/s on 1,050W and the BM-S1 Max to 7 TH/s on 1,600W, all of which let an operator trade hashrate for efficiency when electricity prices move against them. The SC6-SE runs at 17 TH/s and 3,330W or it runs not at all, so factor that inflexibility into the decision if your tariff varies seasonally or by time of day.

Up to 80 decibels from four fans running to 6,000 rpm, which makes it among the loudest machines in the Blake2B range, louder than the 75 decibels of the iBeLink models and far beyond the 55 of Goldshell's own SC Lite or the 35 of the SC-BOX II. This is farm hardware. It needs a dedicated building or plant room, not a garage sharing a wall with living space. At 3,330W it sheds roughly 11,360 BTU per hour that has to leave the room, and the operating window is narrow at 0 to 35 degrees Celsius with humidity up to 65 percent, so hot or humid sites need genuine ventilation planning. Give it a clear intake at the front and an unobstructed exhaust path, and make sure hot air cannot recirculate to the front.

Because J/TH figures only compare between machines running the same algorithm. A current Bitcoin ASIC quotes around 13 J/TH, but it performs completely different computational work against a different difficulty scale, so the two numbers are not commensurable and setting them side by side tells you nothing useful. Every Blake2B machine reads poorly against Bitcoin hardware. The ranking that carries information runs within the algorithm, from the iBeLink BM-S3+ at about 136 J/TH down to the BM-S1 at about 346, and the SC6-SE at about 196 sits fourth in that field and first among Goldshell's machines.

It is the top of it on both measures. The SC6-SE gives 17 TH/s at about 196 J/TH. The SC5 Pro gives 11 TH/s at about 256, the SC Lite 4.4 TH/s at about 216, the SC-BOX II 1.9 TH/s at about 211 in default mode or 1.45 TH/s at about 179 in low power mode, and the original SC-BOX 900 GH/s at about 222. So the SC6-SE is the fastest and most efficient Goldshell machine, though the SC-BOX II in low power mode is more efficient per terahash while producing a fraction of the output. The other machines in the range are also far quieter, from 35 to 55 decibels against this machine's 80, so moving up the Goldshell range means accepting industrial noise and power for the first time.

Siacoin is the primary target, with ScPrime a much smaller secondary option on the same Blake2B algorithm. Blake2B hardware offers nothing like the flexibility of a SHA-256 machine that can be moved between Bitcoin, Bitcoin Cash and numerous other chains as economics change, so this is concentrated exposure to one project, and at this power level that deserves weight in the decision. It cannot mine Bitcoin, Litecoin on Scrypt, Kaspa or anything outside Blake2B. Note that at least one retail listing wrongly describes this model as a Blake2S miner targeting Kadena. It is neither.

That depends on the Siacoin price, Sia network difficulty and your electricity rate, and on a small capitalisation network the first two move faster than they do on Bitcoin. At 3,330W continuous the tariff is the dominant variable you control, and because there is no low power mode you cannot dial the machine back if prices move against you, which makes the electricity question sharper here than on most of the range. Published daily figures for this model vary between sources and date quickly, so use them for nothing. Run your actual rate through the live calculator, model a range of Siacoin prices rather than one, and consider hosting at industrial rates, which on a 3.3 kilowatt machine often decides whether the economics work at all.

Distributors commonly publish six months on new units, though terms vary by channel and batch, so confirm at order, and note that Goldshell is a smaller manufacturer than Bitmain so spare parts and independent repair options are thinner. Power supply inclusion also varies across Goldshell's range, so confirm what ships with your unit. Maintenance is standard air cooled upkeep at industrial scale: clean the four fans and heatsinks on a schedule, inspect connectors periodically, hold the unit inside its 0 to 35 degrees Celsius window and treat fans as the wear item, particularly at 6,000 rpm. MillionMiner operates managed US facilities with the industrial power and ventilation this class needs, which is worth quoting alongside the hardware since electricity is the dominant running cost, and we ship worldwide DDP with customs, duties and taxes handled.
