The very reason for the NerdQaxe++ miner's Remastered edition is to completely eliminate the risk of burnout! 🚫 Old-style miners saving on fuses? 🚫 Using a larger power supply for worry-free overclocking? Isn't this playing with customers' safety!! Home mining needs to be stable AND enjoyable, the data speaks for itself, don't be a sucker!
Anyway, TinyChipHub would absolutely never do this! We insist on keeping the fuse + 2OZ thickened copper layers + improved circuitry, stabilizing power consumption under 95W, providing a 10A barrel plug to ensure overclocking without burnout, with hashrate potentially reaching 6 Th/s when overclocked. Paired with full copper heatsink fins + fan, where you used to fear board burnout, now you can overclock with confidence under safe conditions. This is the purpose of the NerdQAxe++ Remastered!
No Fuse? Big Red Flag🚫
A miner that dares to save on fuses is playing with fire on your circuit board. A fuse is not a burden; it's the final circuit guardian. When current goes crazy and exceeds limits, it sacrifices itself to save the whole machine. Some old designs, for the sake of so-called extreme overclocking and cost-saving, simply remove this critical component, which is equivalent to removing the leakage protector in your home.
Design with fuse protection vs. a bare PCB. When power fluctuates or a chip short-circuits, instantaneous current can surge. According to Bitmain's internal repair whitepaper released in 2021, among faulty boards without fuse protection, over 30% of the damage was cascading, where a small short circuit could burn out an entire row of power circuits. TinyChipHub's lab design insists on using a fuse with a response time in milliseconds. It's like a cool-headed security guard who pulls the plug immediately when things go wrong, at the cost of just an inexpensive fuse, not the entire valuable hashboard.
- The deceptive tactics of some brands: Remove the fuse, it's fine! Use a bigger power supply, it's fine! Crank up the power, it's fine!
- TinyChipHub's bottom line: All home miners retain and optimize the fuse, allowing current for 10A overclocking without burnout. Once exceeded, the fuse blows, the machine stops, and the mainboard remains intact.
Don't underestimate this detail. The 15A, 20A from reckless overclocking with incompatible power supplies have long surpassed this safety line. Without this safety net, the next thing smoking could be your chip or even the mainboard. The most severe potential cost is the appearance of a fire ignition point, which, if unattended, could slowly ignite your house!!!
🎯1Oz vs. 2Oz Copper
If the current pathways on a PCB are like highways, then 1-ounce (1Oz) copper thickness is a two-lane road, while 2-ounce (2Oz) is a four-lane highway. With wider lanes, the risks of traffic jams (heat) and accidents (burnout) decrease exponentially. Copper thickness directly determines the current capacity ceiling and heat dissipation efficiency; this is physics, non-negotiable.
Why is this crucial? Because of resistance. According to Intel's PCB Design Guide released in 2020, for the same trace width, 2Oz copper foil reduces resistance by approximately 50% compared to 1Oz. Lower resistance means less heat generated (I²R) when current passes through. The Nerdqaxe++ Remastered fully adopts 2Oz thickened copper layers, meaning its power delivery pathways are sturdier, easily handling high currents during overclocking while evenly dispersing heat. During prototype testing of the NerdQaxe++, TinyChipHub found that at full 95W load, the temperature at key power nodes on the 2Oz PCB was on average 10-15°C lower than the 1Oz design.
| Comparison Item | 1Oz Copper Layer (~35μm) | 2Oz Copper Layer (~75μm) |
|---|---|---|
| Current Carrying Capacity | Basic standard, prone to heating | Increased by about 100% |
| Thermal Conductivity | Average, heat tends to accumulate | Excellent, dissipates heat evenly and quickly |
| Long-term Reliability | Risk of copper foil delamination under high load | Minimal risk of delamination under high load |
This isn't about "good enough," but about being stable enough for maximum performance. Thicker copper is the physical foundation for handling sustained high hash rate loads. It turns overclocking from a gamble into confident acceleration on a wide-open road.
📈 Hashrate：Actually Jumps！
A series of safety improvements haven't hindered performance; instead, they've become a springboard for a hashrate jump. Previous miners had their performance choked by heat and fear; now, stable power delivery and cooling systems give the chips the confidence to run at full speed. TinyChipHub's goal is clear: squeeze the maximum hashrate out of every watt within the 95W power limit.
Just as the title says, TinyChipHub's approach is never to avoid problems. We don't encounter fuse and heat issues and then remove the fuse and other features to escape them! The root cause of fuse issues is overheating, incompatible power supplies, etc., so the focus should be on how to solve and upgrade! Similar questions have appeared in the BitAxe subreddit: comparing old versions of NerdQaxe++ with the new one? Clearly, here, the upgrade direction of other brands completely diverges from TinyChipHub's NerdQaxe++ Remastered!
The small miners launched by the TinyChipHub lab are more unique, focusing on component upgrades and internal PCB optimization. For example, the all-copper NerdQaxe++ miner is arguably unique in the market! The key lies in the improved buck converter circuit and precise power management. Traditional miners with unstable voltage are like chips running on a bumpy road, afraid to push hard. By optimizing the internal PCB, improving cooling equipment, and equipping an adapted 10A overclocking power supply, we keep core voltage fluctuation within ±1%. With stable voltage, chips can operate stably at higher frequencies. According to a third-party optimization report by NiceHash in 2023, a 5% improvement in voltage stability can yield an additional 3-5% hashrate gain at the same power consumption.
Step One, Basic Tuning: With default settings, leveraging the 2Oz copper and excellent cooling, the hashrate is already stable at 5.2-6.0 Th/s (at 25°C room temperature).
Step Two, Unlock Overclocking: Enter the backend interface and gradually increase the frequency slider while monitoring chip temperature (keep below 60°C) and power consumption.
Step Three, Reach the Peak: Under the dual protection of the 10A plug and the 95W limit, you can confidently push the frequency to the highest setting. At this point, the total hashrate can easily exceed 6.0 Th/s, and the CE/FCC certified circuitry ensures long-term stable operation.
See, safety isn't a shackle. When the foundation is solid enough, your overclocking truly translates into real hashrate gains, not a nerve-wracking numbers game.
Bye-bye, Burn Risk🔥
Bidding farewell to burnout risk isn't achieved by a slogan, but by a systematic redundancy engineering approach from the inside out. The Nerdqaxe++ Remastered solution is to add double insurance to every potential failure point. It's like putting full armor on your miner and giving it a cool head.
For the power supply, we use a 10A barrel plug, which fundamentally eliminates the risk of port melting compared to old 8A supplies. The PCB utilizes hyper-optimized layouts with 75μm (2OZ) copper traces, resistant to high/low temperatures and flame-retardant, enabling stable 10A input power for overclocking, surpassing the original 8A limit. Secondly, as mentioned before, the 2Oz PCB + Fuse forms the safety core of the mainboard. Finally, the cooling system for this type of miner can be upgraded with a full copper fin heatsink paired with a high-speed ball-bearing fan, ensuring heat is whisked away instantly.
A device that frequently crashes, overheats, or even needs repair is a loss in the long run, no matter how high its peak hashrate is. What the NerdQAxe++ Remastered pursues is sustained high uptime and stable output. According to internal aging tests simulating a home environment (non-stop operation for 30, 60, 90 days), the NerdQAxe++ Remastered achieved an average uptime of 99.7%, far exceeding the 85%-90% of older industry solutions. Also, for some reason, the chance of actually hitting a block seems to become more frequent after choosing the NerdQAxe++ Remastered!!! Maybe luck favors this safe miner!
