PC power supply continuous miner

1.

At present, the mining machines in the market are mainly divided into two categories, one is PC based mining machine, the other is professional mining machine based on ASIC chip

the general PC mining machine can be used as a home computer, but the CPU performance is weak and the power consumption is high. Professional mining machine based on ASIC chip can not be used as ordinary computer because it has no graphics card and does not support mainstream desktop operating system

extended data:

mining machine is one of the ways to obtain bitcoin is a kind of network virtual currency proced by open source P2P software. It doesn't rely on a specific currency institution to issue, but is generated by a large number of calculations of a specific algorithm. It uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions economically. The decentralized nature of P2P and the algorithm itself can ensure that the currency value cannot be manipulated by mass proction

any computer can become a mining machine, but the profit will be relatively low, and there may not be one in ten years. Many companies have developed professional mining machines, which are equipped with special mining crystal. They are tens or hundreds of times higher than ordinary computers

mining is actually a competition of performance and equipment. The mining machine composed of many graphics cards, even if it is just a garbage card like hd6770, can surpass the single graphics card of most users in terms of computing power

and this is not the most terrible. Some mining machines are made up of more such graphics card arrays. When dozens or even hundreds of graphics cards come together, the graphics card itself costs money. Considering the hardware price and other costs, there are considerable expenses in mining

in addition to the display card burning machine, some ASIC (application specific integrated circuit) professional mining machines are also put into the battlefield. ASIC is specially designed for hash operation. Although the performance may not be able to kill the display card in seconds, it is already quite strong. Moreover, because their power consumption is far lower than that of the display card, it is easier to form scale and the electricity cost is also lower, It is difficult to compete with these excavators. And this kind of machine will be more expensive

You can't dig in a day. It takes 2000 years

the global unified computing difficulty of bitcoin is 2621404453 (expected to change in two days). It takes more than 2000 years for a 2.5GHz CPU to work out a bitcoin

in order to make the graphics card fully loaded for a long time, the power consumption will be quite high, and the electricity bill will be higher and higher. Many professional mines at home and abroad are operated in areas with extremely low electricity charges, such as hydropower stations, while more users can only mine at home or in ordinary mines, so the electricity charges are not cheap. Even in a certain residential area in Yunnan, there was a case of crazy mining, which led to a large area trip of the residential area, and the transformer was burned

extended data:

bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system

bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network can get a qualified answer about every 10 minutes. Then bitcoin network will generate a certain amount of bitcoin as block reward to reward the person who gets the answer

when bitcoin was born in 2009, block rewards were 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the block reward will be halved to 25

when the total amount reaches 15.75 million (5.25 million new output, i.e. 50% of 1050), the block reward will be further halved to 12.5. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to about 21 million

3. It can be, but it can't compare with others

the money g can't fill the electricity bill hole
the configuration of home computers is low, and the computing power of graphics card can't keep up,
mining machines are generally equipped with server power supply<

now mining mainly relies on graphics card (GPU), ordinary home computers, which may be able to dig a coin for hundreds of years

now mining has entered the era of specialization and clustering. Without professional mining machines, there is no profit (because you have the cost of electricity). How can you compete with tens of thousands of other machines. If you really want to do mining, Jianye will buy a special miner to join in the large-scale mining pool.

4. If the power supply is broken, replace it directly. It must be because the power supply is broken, the output current is unstable or the output current is unstable. The function of the power supply is to convert alternating current into direct current. Half of it is not repaired, and it is not expensive. Just buy a new one

5. It's normal for you
1) ant S3 miner, I saw several comments from friends in the Forum
the official power consumption is 332w, and businesses usually report 355w
the actual power consumption is about 390W
2) your power supply is rated at 500W, which is basically 400W after decting the conversion loss
theoretically, it should be able to drive,
however, for the consideration of long-term stability, the miner generally requires higher power supply when designing
the fault tolerance between 390W and 400W is less
therefore, we all use 600W rated power supply in the forum and online evaluation
(Rated 600, not the highest 600)

the stability of mining machine is very important. A stable and suitable power supply will definitely save you a lot of trouble in the future

some suggestions for your reference

6. If you want to use the switching power supply of the computer for other purposes, you can change it as follows:
1. Open the iron box of the power supply, take out the circuit board from the box, and use a brush to remove the st
2. Find the key components. Including: power oscillation integrated block, optocoupler, 12V voltage regulator, pulse width adjusting potentiometer, etc. Find the information of power supply mole
3. First, change the 12V voltage regulator into 15V, and find the pulse width adjustment circuit according to the data of power supply integrated block. Some power supplies do not design power supply fine-tuning, but fixed resistance. Remove the fixed resistance, and connect a potentiometer whose resistance value is basically close to the welding resistance on the two solder joints. Now adjust the resistance of the potentiometer to the maximum
4. Use a multimeter to monitor the 12 V power supply port, turn on the power supply, slowly rece the resistance of the potentiometer, observe the voltage change, and adjust it to 15 v. After stabilization, observe for a little time and connect the false load toaster
5. After it is accurate, measure the resistance of the potentiometer and replace it with a fixed resistance with the same resistance.

8. Isn't there a popular bitcoin digger before ~ ~ ~ that kind of computer that runs for a long time without shutting down seems to be called a digger by some people~
