Goldshell SC5 Pro II Ultra Description
The Goldshell SC5 Pro II Ultra is a used upgrade of the standard SC5 Pro II, offered at 24 TH/s and 5780 W for Blake2B-Sia mining. Calculated efficiency is approximately 240.83 J/TH, with estimated electricity use of 138.72 kWh per day at continuous nominal power.
This configuration requires a dedicated mining space with suitable electrical capacity, ventilation and noise management. Confirm the supplied PSU ratings, cable connections and actual unit specifications before installation; standard 14T model specifications should not be assumed.
BTCB2 compatibility remains subject to exact-unit and firmware verification. Siacoin revenue estimates do not represent BTCB2 earnings. Compare electricity costs, purchase condition, pool fees and uptime, then review the specifications and FAQs before choosing this upgraded miner.
Goldshell SC5 Pro II Ultra 24T vs iBeLink BM-S3+
| Specification | SC5 Pro II Ultra 24T (used upgrade) | iBeLink BM-S3+ |
|---|---|---|
| Mining algorithm | Blake2B-Sia | Blake2B-Sia |
| Reference hashrate | 24 TH/s | 25 TH/s |
| Reference power | 5780 W | 3400 W |
| Calculated efficiency | 240.83 J/TH | 136 J/TH |
| Energy per 24 hours at reference power | 138.72 kWh | 81.60 kWh |
This comparison uses the BT-Miners Ultra upgrade listing, not the standard 14 TH/s SC5 Pro II. On these reference values, the BM-S3+ offers approximately 4.2% more hashrate, draws 41.2% less total power and uses 43.5% less energy per unit of hashrate. Lower J/TH means better energy efficiency.
The daily energy difference is 57.12 kWh before external cooling. Multiply that difference by your electricity tariff to compare running costs. Purchase price, used condition, firmware support and actual measured wall power also affect the decision. These calculations do not establish profitability or BTCB2 compatibility.

FAQs
-
What Is The Lifespan Of This Mining Machine?
The lifespan of mining hardware is influenced by usage intensity, environmental factors like temperature, humidity, and dust. Proper maintenance and optimal conditions can significantly extend its longevity.
-
How Does Electricity Cost Impact Profitability?
Electricity costs play a crucial role in mining profitability, as high rates can quickly offset profit. Therefore, it is vital to access local electricity costs to determine if mining is viable. With high electricity costs and high liquidity of digital assets, investing in an energy-efficient miner becomes even more important.
-
Which SC5 Pro II configuration does this listing offer?
This listing offers the used Goldshell SC5 Pro II Ultra upgrade at 24 TH/s and 5780 W. It is different from the standard 14 TH/s SC5 Pro II. Confirm the actual unit, upgrade configuration and firmware before ordering; standard-model electrical and physical specifications should not be transferred automatically.
-
What are the Ultra 24T hashrate, power and efficiency?
The BT-Miners Ultra configuration is listed at 24 TH/s with 5780 W nominal power. Dividing these values gives approximately 240.83 J/TH. This is a calculation from the listed configuration, not an independently measured efficiency result. Actual wall power and hashrate should be checked for the supplied unit.
-
How much electricity does the SC5 Pro II Ultra use per day?
At a constant 5.78 kW for 24 hours, consumption is approximately 138.72 kWh per day. At US$0.10/kWh, that is about US$13.87 per day for the miner alone. External cooling, downtime and changes in operating power affect the actual total.
-
What electrical supply does the 5780 W Ultra configuration require?
Confirm the voltage range, PSU arrangement, input connectors and continuous current requirements of the supplied Ultra unit before installation. Do not treat the standard SC5 Pro II power cable specification as the circuit rating for this upgrade. A single 16 A supply at 230 V is insufficient for a 5780 W load. Have the complete installation sized for the actual equipment and local electrical requirements.
-
Is the SC5 Pro II Ultra suitable for quiet home mining?
Plan for a dedicated mining area with substantial heat removal and noise management. A verified noise measurement for the Ultra 24T configuration is not available on this listing, so it should not be treated as a quiet desktop miner. Confirm ambient temperature and humidity limits for the supplied upgraded unit.
-
Is BTCB2 compatibility confirmed for the SC5 Pro II Ultra?
BTCB2 compatibility remains pending verification for the exact Ultra unit and firmware. A matching algorithm name or support for another SC5 model is not sufficient. Confirm the target chain, firmware, pool connection, accepted shares and payout before relying on compatibility. See the BTCB2 mining and compatibility guide.
-
How do I connect this miner to a mining pool?
Use Ethernet to connect the miner to your network, open its management interface and configure the selected compatible pool and worker settings. Use a wallet for the correct chain and verify accepted shares and payouts. Siacoin and BTCB2 setup details must not be treated as interchangeable. Follow the pool setup and share verification guide when assessing BTCB2 operation.
-
Does this used Ultra miner include a power supply and cable?
The listing includes a power supply and protective packaging. A power cord is not listed as included. Confirm the PSU arrangement, connector types and required cables for your selected unit before installation. The listed used-miner warranty is seven days, subject to the applicable order terms.
-
How does the Ultra 24T compare with the iBeLink BM-S3+?
Using 24 TH/s and 5780 W for this Ultra listing versus 25 TH/s and 3400 W for the BM-S3+, the BM-S3+ provides about 4.2% more hashrate with 41.2% lower total power. Its calculated energy use per unit of hashrate is about 43.5% lower. Compare price, condition and actual unit performance as well as these reference figures.
-
How should I estimate profitability for this miner?
Use revenue data for the actual coin and supported operating mode, then subtract electricity, pool fees, cooling, hosting and maintenance. At listed power, daily miner electricity cost is 138.72 multiplied by your tariff per kWh. Siacoin estimates do not establish BTCB2 earnings. Coin prices, network difficulty and uptime change results; no daily profit or payback period is guaranteed.
