What is the power consumption of graphics card miner
the power consumption of bitcoin mining machines is different according to different machines take Shenma 68T, the fastest mining machine in wet season, as an example. Suppose that the electricity charge is 0.22 per kilowatt hour in half a year in wet season and 0.34 per kilowatt hour in dry season, the wall power consumption of Shenma 68T's second-hand machine is 3264w, and the actual power consumption is 3500W, then the daily power consumption of a Shenma M20S 68T machine is 3.524 = 84 degrees, Annual power consumption 84 * 365 = 30660 degrees
according to the latest mining difficulty, a Shenma 68T machine can dig 0.00064836 BTC a day, and 10 machines can dig 2.366514 coins a year. The mining difficulty of the premise remains unchanged, but according to the current situation, it is assumed that the mining difficulty will increase by 30% from now to next June, and by 2.5% every month. It is estimated that 85% of the original coins should be g, that is, 2.012 coins. Ten machines of Shenma 68T can dig almost 2 coins a year
to sum up, the power consumption of ten Shenma 68T machines in a year is 306600 kwh, which can dig almost two coins

the risk of mining machine
1. Hardware expenditure
< P > mining is actually a competition of performance and equipment. Some mining machines are composed of more such graphics card arrays. With tens or even hundreds of graphics cards, the hardware price and other costs are very high, There is considerable expenditure in miningin addition to the display card burning machines, some ASIC (application specific integrated circuit) professional mining machines are also put into the battlefield. ASIC is specially designed for hash operation, and the computing power is quite strong. Moreover, because their power consumption is far lower than that of the display card, they are easier to form scale, and the power cost is also lower. It is difficult for single chip display to compete with these mining machines, This kind of machine costs more
2. Currency security
the withdrawal of bitcoin requires hundreds of keys, and most people will record this long string of numbers on the computer, but the frequent problems such as hard disk damage will make the key permanently lost, which also leads to the loss of bitcoin
3. System risk
system risk is very common in bitcoin, and the most common one is bifurcation. Bifurcation will lead to a drop in currency price and a sharp drop in mining income. However, many cases show that the forking will benefit the miners, and the forked competitive currency also needs the miners' computing power to complete the minting and trading process. In order to win more miners, the competitive currency will provide more block rewards and handling charges to attract miners. Risk makes miners
For example
a 4-sheet R9 280x graphics card miner. About 2.9m
power consumption:
the rated power of each graphics card is about 250W, and slightly overclocking is about 300W. Four graphics cards, 1200W
platform: motherboard, CPU, hard disk, etc., which add up to no more than 200W
display, mining machine is basically no display
the total power is about 1400W. 33.6 degrees a day
if the caption is only for ordinary household desktop computers, it is not easy to calculate, because the key is the power consumption of the graphics card. The power consumption of ordinary graphics card is about 150W. And then add the others according to 200W, a total of 350W. 4.2 degrees a day
you can think of sending the intercepted URL short message, and then provide the specific location to intercept
if the CPU consumes a lot of power, it will consume more power,
and the graphics card consumes a lot!
RX580 8G is a good performance graphics card. The parameters are as follows:
is AMD graphics card, DDR5256 bit, 14 nm, 2304SP, awesome performance of the graphics card. The power consumption of the graphics card is around 230W. It is recommended that the rated power supply of rated 500W is above. The game performance is almost the same as that of the fine shadow GTX1060 6G, but it can be mined. br />
More than 500W power supply
the full load power of sapphire rx580 is more than 200 watts, plus the power consumption of CPU and other hardware, it needs more than 500 watts of power
The full load power consumption ofrx580 8g is about 200W, and the power consumption will vary with the core and video memory frequency of different brands and models
500 power supply should also pay attention to whether it is rated power. The rated power value is the rated voltage of the electrical equipment multiplied by the rated current. If the actual power of the graphics card is greater than the rated power, the electrical equipment may be damaged; If the actual power is less than the rated power, the graphics card will not work properly
extended data:
rated power: ambient temperature - 5-50 ℃, input voltage 180v-264v, long-term stable output power of power supply
maximum power: at room temperature, the input voltage is between 200V and 240V, and the output power is stable. The maximum power is generally about 15% higher than the rated power. For example, the new Valley nuclear power plant has a power of 325pq, a rated power of 250W, a maximum power of 280W, close to 300W
peak power: the maximum power that the power supply can achieve in a very short time. The time can only last between a few seconds and 30 seconds. The peak power is related to the operating environment and conditions, not a certain value, but it may be very large and easy to mislead users. For example, the rated power of Xingu 325pq is 250W, and the peak power is 350W. Obviously, only the rated power and maximum power have practical significance
The power consumption of rx580 8g is higher, but its performance is better than that of rx570. The power consumption of rx570 is about 150W, and that of rx580 is about 200W
the full load power of sapphire rx580 is more than 200 watts, plus the power consumption of CPU and other hardware, it needs more than 500 watts of power
The full load power consumption ofrx580 8g is about 200W, and the power consumption will vary with the core and video memory frequency of different brands and models
500 power supply should also pay attention to whether it is rated power. The rated power value is the rated voltage of the electrical equipment multiplied by the rated current. If the actual power of the graphics card is greater than the rated power, the electrical equipment may be damaged; If the actual power is less than the rated power, the graphics card will not work properly
