Questions about the power supply of the computer and the power issue

460W Power ???

Your configuration is rated at 200W is enough, if you just surf the Internet, the general power consumption is about 120W!

The power supply is added by 60W, it is not that 60W more electricity is used per hour, and the actual meter is related to the configuration and application.

The power of the power supply refers to the power of the host, and the display is not counted.

No, the power consumption of your computer is only related to the total power of the accessory. If the CPU, motherboard, graphics card and other accessories remain unchanged, the power consumption is basically the same. It has little to do with the size of the power supply.

Here's a come over calculator:

Your total power consumption does not exceed 200W

CPU: AMD5000 65 watts max.

Motherboard: Yingtai MCP6P motherboard 25 watts.

Memory: You are 2 5w*2

HDD: 80g 15 watts.

Let's say you don't have a discrete network card with integrated graphics.

Optical drive less than 35 watts.

3 watts for the keyboard 5 watts for the mouse, assuming you can install 10 fans 3*10 watts for a total of less than 200 watts.

400 watts of power are wasted.

However, the power supply does not use 460 watts of power for 460 watts, but uses as much power as your computer consumes.

It should also be noted that the power supply itself has a loss of conversion efficiency, and in the end, the power consumption of your computer should use the actual power consumption of the usual time (far less than the maximum of 200, more than 100), except for the conversion efficiency of the power supply (about 75%)

The wattage of a power supply is its output power, not how much power it consumes.

In other words, the power consumption of all your hardware must not be greater than the output power of the power supply, otherwise it will go wrong.

Your configuration buys 460w, if it's rated 460w, it's too wasteful.

1 kWh 1000w h

Your current power supply is 460W, which is 460 1000, so it consumes 1 hour of power.

Of course, there is an impact, the impact is very large, if the power supply is insufficient, it will cause the computer processor graphics card to reduce the frequency, and the heavy may cause hardware damage, crash restart, and the power supply is too high.

P4 dedicated power supply, the rated power is above 250W.

The power supply is one of the most important accessories in the computer, although it has nothing to do with performance, but its stability is very important, if the power quality is not good, the computer will not work unstable or unable to work normally, and the computer accessories will be damaged and may even cause fire, electric shock and other accidents.

The rated power of the power supply is generally determined by the power consumption of the host to 2 times, too low may be insufficient power supply, too high investment, and the power efficiency may be reduced, according to the 80plus demonstration standard and the efficiency curve of the general power supply, it can be seen that the power supply is dismantled at the load rate of 40%-60%, and the efficiency is the highest.

1. Different power: The first point is that the output power of the two is different, the general PC, 300W power is enough, but with a good graphics card, and a good CPU, maybe the 300W power is still relatively small, and it should be replaced by a high-power power supply.

2. **Different: 400W power supply and 300W power supply are different from roommates, 300W power supply is more expensive than 400W power supply, but it can drive a better hardware system.

1. Low-end office and home use: the processor below the i3 level is used, the core graphics card or an independent graphics card not higher than 1,000 yuan is used, the power is low, and the power supply rated at about 300W is recommended. 2. Mid-range game platform:

Using a quad-core processor + no more than 2,000 yuan within the independent graphics card, you can play online games and play some large-scale 3D games with low special effects, the power consumption of the whole machine is about 200-300W, and it is recommended to choose a rated 450W 650W power supply. 3. Extreme fever host: i7 level processor and independent graphics card above 2000 yuan, power supply power is recommended to start at 500W, this part of the players are generally experienced DIYER, the power needs to be very clear, more interested in the quality of the power supply, I believe that the power supply similar to the extreme firepower 80plus platinum certification can reach their level.

1. The power supply of the computer is generally selected if the power of the platform is greater than the value. In general, the main method is to compute for the platform's CPU and graphics card. Because these two parts are the main power consumers.

2. Query the power consumption of your CPU or graphics card through the network, which is generally greater than the rounding, and the additional 50 watts are no problem for the normal platform.

3. The power of the power supply can be divided into: rated power, maximum power, and peak power. The power of the power supply can be divided into:

Rated power, maximum power, peak power. Rated power: the ambient temperature is between -5-50 degrees, the input voltage is between 180V-264V, and the power supply can be stably output for a long time.

Maximum power: At room temperature, the input voltage is between 200V-240V, and the power supply can be stably output for a long time, and the maximum power is generally about 15% larger than the rated power.

Insufficient power supply is an absolutely unacceptable problem for computers.

First, we need to focus on a conceptual ......Is the computer working without power? The answer is yes, and then there is the ...... of insufficient powerIn the summer, when the electricity is at its peak, we often find that the lights are dimmed.

Computers are ...... the sameIf the power supply is insufficient, the computer will not work properly.

For example, a slight power supply shortage may cause a one-time failure to turn on the computer because the capacitor of the CPU power supply is simply not able to complete the one-time full charge ......You need to press restart once after turning on the computer for tens of seconds before it can turn on the ......This is the slightest.

Serious power supply is insufficient, or unstable ......As soon as you read the disc with the optical drive, it crashes and restarts ......The hard drive occasionally emits a sound......It didn't take long for the hard drive to get corrupted.

When running, the screen often goes black......Or the blue screen.

and so on, all of which are ...... when the power supply is unstableOverclocking behavior counts separately ......

In short, the power supply is not enough ......Minor ones only affect normal use. Serious ones can really damage the hardware.

There are two causes of insufficient power supply. The computer has been upgraded or overclocked, and it turns out that the power supply that is just enough is not enough ......This is more obvious ......Power losses caused by general upgrades are not considered ...... serious amountsBasically, it is a situation where the computer cannot be turned on at one time, or it cannot be turned on......

As for the second one, it's not good to buy a virtual standard power supply......That kind of power supply is generally unstable in continuous power supply. ...... that caused the overall hardware system to dangleEventually damage components such as hard drives......This is a dangerous ......

It is recommended to choose a first-line brand power supply. Such as Huntkey, Aname, Great Wall and other old power supply ......

Restart, old power outage, especially during peak electricity consumption periods.

It is easy to fail to start, so that the power supply is easy to run out of the load power supply, in the long-term boot, high ambient temperature and full load operation of the computer, there will be unstable power supply, insufficient, affecting the operation of the computer, the more direct is easy to crash, stuck and blue screen; Long-term use not only accelerates the aging of the power supply, and then the performance decreases (the electrical properties of the components decrease, easy to fluctuate, etc.), so that the power value is lost, but also directly affects the health and life of other computer accessories (hard disk-motherboard--CPU continues to eat), and the power exceeds the limit, then it can only be automatically shut down and powered off.

The light does not light up, the voltage is unstable, and the power is turned on for a period of time.

The machine is unstable, or it simply does not turn on.
