Goldshell SC5 Pro II Description
The Goldshell SC5 Pro II is a Blake2b ASIC miner for Siacoin. Goldshell specifies the standard model at 14 TH/s and 3300 W, equivalent to approximately 235.71 J/TH. At that reference power, continuous operation uses 79.2 kWh daily before external cooling.
This listing also offers used configurations with different hashrates and power figures, including a 24T upgrade. Choose the exact option and confirm its measured power, PSU requirements and condition. Standard model specifications do not automatically apply to upgraded units.
Ethernet networking, ventilation and industrial noise management are required. B2Pool documentation names the SC5 Pro II for BTCB2, but unit compatibility, accepted shares and payouts need verification. Evaluate electricity costs using revenue for the selected coin, without assuming guaranteed profitability.
Goldshell SC5 Pro II vs Goldshell SC5 Pro (standard)
| Reference specification | Goldshell SC5 Pro II (standard) | Goldshell SC5 Pro (standard) |
|---|---|---|
| Algorithm / coin | Blake2b-Sia / SC | Blake2b-Sia / SC |
| Reference hashrate | 14 TH/s | 11 TH/s |
| Reference power | 3300 W | 2820 W |
| Calculated efficiency | 235.71 J/TH | 256.36 J/TH |
| Energy per 24 hours | 79.2 kWh | 67.68 kWh |
At these reference ratings, Goldshell SC5 Pro II offers 27.3% more hashrate and 8.1% lower energy use per unit of hashrate. Daily energy assumes 24 hours at reference power and excludes external cooling. Compare purchase price, unit condition and actual wall power; these figures do not establish profitability.
Current store options: 11.8T Used 3150W; 14T Used 3400W; 15.8T Used 3450W; 24T Used 5780W. These are seller-listed configurations, not the manufacturer standard modes compared above. Confirm the actual unit model, firmware, PSU rating and measured performance before ordering.

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.
-
What hashrate and power should I use for the Goldshell SC5 Pro II?
The reference is 14 TH/s at 3300 W, giving calculated efficiency of 235.71 J/TH. The current store options are 11.8T Used 3150W; 14T Used 3400W; 15.8T Used 3450W; 24T Used 5780W. Use the selected configuration rather than assuming the standard rating applies to every unit.
-
How much electricity does the Goldshell SC5 Pro II use per day?
At 3.3 kW for 24 hours, estimated energy use is 79.2 kWh. Daily miner electricity cost equals 79.2 multiplied by your price per kWh. This excludes external cooling, downtime and other equipment. For example, the 24T/5780W option would use 138.72 kWh per day at its listed power; it must not be costed using the standard rating.
-
What voltage does the Goldshell SC5 Pro II require?
The published reference input is 185-285 V AC. Check the supplied PSU label, connectors and circuit capacity before installation. Goldshell lists a 16 A power cable specification for the standard model; this is not a measured current draw or a cable recommendation for upgraded configurations. A 110 V or 120 V outlet is outside this published range; a plug adapter does not change supply voltage.
-
How loud is the Goldshell SC5 Pro II, and where should it operate?
The published noise reference is ≤85 dB (standard model). This air-cooled industrial miner produces continuous fan noise and heat. Use a dedicated ventilated space with noise management rather than a bedroom or quiet office. The reference ambient operating range is 0-35 °C; keep intake airflow unobstructed.
-
Which coins can the Goldshell SC5 Pro II mine?
This is Blake2b-Sia hardware for Siacoin (SC). B2Pool hardware documentation also lists the Goldshell SC5 Pro II for BTCB2. A pool listing is not verification of every firmware revision or upgraded unit. This ASIC does not mine SHA-256 Bitcoin. Confirm the target chain and pool compatibility before switching.
-
How do I verify Goldshell SC5 Pro II support for XBT or BTCB2?
Use current exact-model pool instructions, check firmware support, and verify accepted shares followed by an actual payout to the correct wallet. XBT can name different assets on different services; confirm the chain rather than relying on the ticker alone. Read the XBT/BTCB2 naming and compatibility guide. Siacoin earnings estimates do not establish BTCB2 revenue.
-
How do I connect and configure the Goldshell SC5 Pro II?
Connect Ethernet to your router or switch and use a compatible electrical supply. Find the miner IP address, open its management interface and enter the selected pool URL, worker and wallet details according to that pool. Change default credentials and monitor accepted shares, hashrate, temperatures and rejected shares after setup. Do not assume a generic login applies to every unit.
-
Does this Goldshell SC5 Pro II listing include a PSU and power cord?
The package fields list a power supply and protective packaging. A power cord is not listed as included. Confirm the actual PSU, connector type and suitable local cable for the selected unit. Read the displayed warranty for the selected condition; accessories and electrical requirements can differ for upgraded or substitute machines.
-
Are the listed used options the same as Goldshell SC5 Pro II low-power mode?
No. Goldshell lists a standard low-power mode of 10 TH/s at 2050 W, with ±5% ratings. The store options (11.8T Used 3150W; 14T Used 3400W; 15.8T Used 3450W; 24T Used 5780W) describe separate seller-listed configurations. Do not assume those configurations retain standard low-power behavior, dimensions or PSU requirements. Request the actual configuration details before purchase.
-
How should I estimate profitability for the Goldshell SC5 Pro II?
Use the selected unit hashrate, measured power, electricity tariff and current revenue for the actual coin. Include pool fees, cooling, hosting, downtime and maintenance. Compare these costs with the purchase price and unit condition. Network difficulty and coin prices change, so neither fixed daily profits nor a payback period can be guaranteed.
