What is the difference between a computer power supply 220W and 330W?

1. The rated power of the power supply refers to its working capacity

W can load 220W power and work normally, 330W can load 330W power and work normally.

w and 330w are not necessarily the state in which they actually occur.

4. The power of the computer is the sum of the power of the CPU, memory, motherboard, hard disk, graphics card, etc.

5. The choice of power supply should be determined by considering the total power of the computer and the brand.

330W supports more devices to run at the same time than 220W, which is stable operation. If you have a lot of accessories on your computer, you can choose a high-power power supply, and safety is more important, but now it is generally a 300W power supply.

Your configuration can be configured with an AMD 570X chipset motherboard or a 780G integrated graphics chipset crossfire configuration, personally recommended 570X. Jabber Hummer HA02-GT - 599 yuan.

The rated power of the power supply of 300W is sufficient, if you are afraid of instability, you can choose 350W. The Great Wall and Huntkey are available.

According to your configuration, if you don't plan to upgrade to a high-end graphics card in the future, a power supply with a rated output power of 300W is enough

Oh, it's the difference in rated output power, if the power of the computer host is relatively high, and the 220W used is not enough to provide power, the problem will come, there will be a crash, restart and other problems, in the long run, the impact on the computer is great

Therefore, in the installation process, it is necessary to choose a good power supply, of course, if your computer configuration is relatively low, the 220W power supply is also sufficient

220w has nothing to do with 220 volts... The difference between 220w and 330w is that half more points are used...

It's better to use 220W, because home electricity is generally 220 volts, and the computer is also designed with 220 volts as the standard, and it is easy to cause the screen to flicker if it doesn't match.

The wattage of power you use depends on the configuration of your computer. A general entry-level low-power CPU, plus a motherboard with integrated graphics, 220W is enough without overclocking. Of course, if it is a more mainstream discrete graphics card configuration, the power supply must be above 300W.

Choose the power supply according to your actual situation, don't let the profiteers fool you.

The difference in the amount of power supplied to the computer, the power supply cannot be mismatched, and it must be configured according to your own computer

If the power supply is low, it may burn out the computer accessories, and if the power supply is high, it may also burn out the computer accessories

Stable, the configuration of the host is related, if the computer configuration is high, it will be more than 300w, or not often restart.

It's like comparing the strength of a 10-year-old child to the strength of an adult.

1. The difference between fast and slow work:

Appliances with a power of 2500W do work more slowly than appliances with a power of 3000W, taking air conditioners as an example, in the same energy efficiency ratio.

The refrigeration and heating effect of high-power air conditioners is better than that of low-power air conditioners, and the refrigeration and heating speed is also faster, because high-power electrical appliances work faster, and the changes in electricity consumption in the same time are greater.

2. The difference in the degree of power consumption:

Theoretically, a 2500W appliance is more power-efficient than a 3000W one. But in reality, a 3000w electric kettle consumes less electricity than a 2500w electric kettle. Because there is heat loss in the process of boiling water.

With less power, the longer it takes to cook, the more electricity is dissipated by heat. However, if it is a 2500W and a 3000W bulb, 2500W is more power-efficient when excluding brightness requirements.

3. A fuse.

Difference in requirements:

The higher the power, the stricter the requirements for the fuse of the appliance, and in the home circuit, the voltage U=220V is certain. Because i=p u, the greater the total power p of the electrical appliance, the greater the total current i in the circuit. If the total current in the circuit exceeds the safe value, the fuse is prone to burnout.

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.

The higher the power of the power supply, the less pressure the power supply will work on

There is no difference in the amount of power. The AT power supply has a total of four outputs (5V, 12V), which provides a PG signal to the motherboard, and the power supply of the motherboard with a power of 150W is a 12-pin split plug, every 6 pins are a plug, there are two of them, and the two black wires should be plugged together, otherwise the motherboard will be burned. The AT power supply is shut down by cutting off the AC power grid.

The greater the power of the power supply, the less the pressure when the power supply is working, for example, the full load power of all the hardware of your computer is 400W, and the rated power supply of 400W is just enough, but the power supply will heat up more powerfully, if you use a power supply with a rated power of 500W, then there is no such concern, do not worry about the power supply, so there is no harm in the power supply with a large power supply.

Key features: From the position and role of the power supply and other aspects of a comprehensive analysis, it can be considered that the performance of the host is superior or not, and the advantages and disadvantages of the power supply also have a great relationship

1. Protection: It has a good self-protection function, and can automatically cut off the power supply to keep the current interception state when the DC current is too large, the voltage is too large, and the no-load or load is short-circuited, and the normal power supply function can also be automatically restored after the fault disappears. 2. Stability:

The output DC is required to be stable, basically no fluctuation, that is, +12V, -12V, +5V, -5V four groups of power supply voltage, current is normal, otherwise it will affect the work of the host. 3. Heat dissipation: The built-in fan of the power supply has a large air volume, which can fully diffuse a large amount of heat released when the power supply is working and prolong the service life of the power supply.

4. Anti-interference: The power supply of *** is not affected by the switch of other electrical equipment. For power supplies with low anti-interference ability, when other electrical appliances are turned on, the microcomputer may produce abnormal phenomena such as self-heating start.

5. Low noise: the components are solid, the power supply fan runs stably, and there is no noise during work. The noisy power supply is mostly caused by the vibration of components, the unbalanced fan blades, the eccentricity of the shaft or poor lubrication, etc., and the power supply with high noise is also prone to failure in use.

6. Compatibility: It should have standard power supply specifications, and must meet the functional parameters of the standard switching power supply (the shell size and fixing screw position are consistent, suitable for various standard chassis), and provide standard stable voltage and current.
