Dismantling of official power supply of ant mining machine

1. He has a bad stomachache

2. BTC broke 100000 yuan today, December 7, 2017

3. This computer room is Zhai Wenjie; mining & quot; It's a good place. These are the machines that Zhai Wenjie modified to dig bitcoin. Eight graphics card almost day and night to calculate, the temperature in the room is significantly higher than outside. Zhai Wenjie said: & quot; A total of 12 mining machines, there are also on the side, because it has too much heat dissipation, you can feel it with your hand, now you can boil eggs. The power consumption is about 60 yuan a day& quot; Sun Minjie & quot; Mining & quot; Our machines have hardly stopped. Sun Minjie said: & quot; Its mining principle is to have a set of very complex encryption and decryption algorithm, do the operation of discrete sequence, and then it is evenly distributed to all the mining people connected to the Internet. In this way, who contributes more computing power will get more& quot;

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. Yinbit is recommended. Yinbit is a maintenance brand of coin printing. It is an official quality maintenance brand established by an old maintenance team. It has five years of ant mining machine maintenance experience and has excellent strength. It can realize the quick repair of ant 17 series and apw9 / apw9 + power supply. It is one of the few maintenance brands in the instry that can quickly repair high computing power models. At the same time, it undertakes the business of rescuing S17 and T17 scrapped computing power boards, At present, there are maintenance sites in Cheng, Sichuan, Dehong, Yunnan and Xinjiang
at the same time, Shenma M20 / M21 series and p21 power supply quick repair can also realize quick repair with quality assurance because they are authorized maintenance brands of Shenma and Xindong.

6. Superposition principle: when each independent power source acts on the circuit separately, other power sources must be set to zero, that is, voltage source short circuit (output voltage is zero), current source open circuit (output current is zero)

7. 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

8. Grounding wire is for safety, not grounding will not affect the normal use

9. ① To solve this problem, if there is 320 V voltage after rectification and filtering, then measure whether the voltage to ground of each pin of the switching power supply stabilized voltage thick mode chip is normal. If there is any abnormality, check the components around the abnormal pin of the chip, such as optocoupler, piezoresistor of sampling circuit As well as the secondary output rectifier filter elements of switching transformer
2. If the components around the above chips are normal, it can be judged that the thick die
chip is damaged.
