Regarding the main engine power supply voltage, a high score is rewarded

I can tell you with certainty that it can't be a problem with the power supply at all. Because the input voltage of the computer is allowed to be between 190-230 volts, that is to say, the voltage will not affect the normal operation of the computer.

Now, the voltage is above 200 volts everywhere, otherwise the power supply company will not send electricity. I am a professional electrician, and if the voltage on the line we are in charge of is too low, we will definitely add a transformer to solve it.

So, I suggest you check if your computer matches the 320g portable hard drive.

When an electrical appliance and multiple electrical appliances are connected in parallel, the requirements for the power supply are the same.

1. The power supply voltage should be equal to the rated voltage of the used voltage.

2. The power of the power supply cannot be less than the total power of the electrical appliances.

V's power supply, the 220V electrical appliances will burn directly, too much higher 4, the power supply will be marked with "2000W" and other numbers, and some write how many volts, how many amps, multiply these two numbers to how many watts of power.

It's time to change the power supply.

The motherboard and the power supply are different parts. The power supply itself has protection circuitry, so even if the motherboard burns out, it doesn't necessarily mean that the power supply has to be broken.

But this power supply, at least there is a dark problem in manufacturing. Or there is an error on the circuit, and the specific fault is only known by testing.

If you are really reluctant to change the power supply, you can get a lightning surge socket, and you can also avoid most of the power surges!

Oh, by the way, I just saw that your power supply is a technical exhibition, and the three-line power supply is not counted, but the four-line power supply is directly on the fourth line, which is close to the cottage power supply. Technically, it is a copycat.

It's not surprising at all to burn your accessories!

Delta NX350. Go buy it and change it! With this power supply, it comes with lightning protection. 100,000 hours of normal use.

True Bronze, Wide Voltage !!

This phenomenon is also normal! The lightning current is directly transmitted to the motherboard through the power supply, and the withstand voltage of the power supply is higher than that of the motherboard!

The instantaneous voltage breaks your computer.

It is recommended that you change to a lightning protection socket in the future, so as to save money...

The fan can be rotated, which can only mean that the wiring is normal, and it cannot be ruled out that there are no other problems with the power supply, and your problem itself is incomplete.

Full 350W is completely OK, the key is whether your rated power of 350W is the real standard, the peak is not considered, the miscellaneous power supply on the market is only about 150W but the nominal 350W or higher.

1. Host power supply.

5V is the "reference voltage" of the host power supply, and its level determines the level of other voltages;

Judging from the second ** of the landlord, it seems that only the +5V voltage is abnormal (red), while the CPU, + and +12V voltages are normal, so there is no reason to suspect the host power supply for the time being;

Second, the main board. From the first chapter**, it seems that the inrush current resistance circuit is activated to protect the system from the impact of the power supply circuit;

Comprehensive analysis of the first and second items, the host power supply and the motherboard have anti-surge current circuits, but the motherboard's +5V comes from the host power supply, which generally only decreases, not increases, and seems to be the fluctuation of the host power supply +5V (reference voltage) that leads to the phenomenon described by the landlord;

The author believes that the possibility of the failure of the host power supply is slightly greater, and it is recommended that the landlord borrow a reliable host power supply to try.

General to the computer city, let the boss confirm to you whether it is a power supply, or the motherboard asked, the warranty has not expired is not money.

The power consumption of a power supply is not determined by its power rating. First of all, it depends on what type of computer host power supply you buy, which is now divided into two categories: active PFC power supply and passive PFS power supply. Active PFC power supplies are environmentally friendly and energy efficient, while passive PFS power supplies are not energy efficient.

Active PFC power supplies have high power conversion efficiency but are a bit more expensive, while passive PFS power supplies are cheap at a low cost.

From the perspective of cost performance, of course, it is the best ideal for active PFC power supply!

Back to your question,If it's an active PFC power supply,The rated power of 500W is just the nominal value,It depends on what the configuration of your computer host is,Generally speaking,4000Yuan or so Intel configuration in the Internet browsing, listening to songs, playing some small games, watching movies, etc., the power consumption is only about 80W,Only when playing large three-D games, the power consumption is the highest,It's about 200W。

But it is also at the price of 4000 yuan, and if it is an AMD configuration, the power consumption will be doubled. Therefore, it is not recommended to choose AMD solutions for hosting purchases with a budget of more than 3,500 yuan.

Finally, the maximum power consumption is only about 200W, is it too high and too wasteful to buy a power supply with a rated power of 500W? Is it enough to use a power supply with a 300W rated power?

The answer is no. Because the power supply has a concept of power margin, you must leave a certain margin on the basis of the total power consumption of the whole machine to ensure the stability of the whole machine and the life of the power supply is effectively extended.

Because the actual power consumption of your computer varies from application to application, it can be difficult to calculate the exact power consumption. Unless you spend dozens of dollars to buy a power monitor for monitoring and inspection. In short, I can only roughly estimate, and the power consumption value I just gave you is a summary of the experience after monitoring by a power monitor.

No, 500 watts is the power rating. For example, if your computer consumes 300W of power and uses a 500W power supply, it is actually only using 300W

500 watts is right to need one kilowatt-hour of electricity in two hours.

500w which only refers to the maximum output power of the power supply is 500w, how much power your computer wants to use is not determined by the power of the power supply, but the sum of the power required by the various hardware composed of the computer when working. Different hardware components have different powers, and the wattage of the power supply is greater than the sum of the power of the computer hardware. Theoretically, 600W is better than 500W, but the power consumption of the whole machine is the same.
