Questions about your computer s power supply? Computer power problems?

It won't be much, and there is basically no difference in electricity consumption between the two.

It's just that the maximum output power of 400W is more than that of 300W, will an adult do more work than a child to move a brick?

If you only move one piece, there is no difference between adults and children, that is, 300 and 400 are the same.

1. The power consumption of A and B computers is the same, and the power consumption refers to the size of the load under the power supply, which has nothing to do with the power of the power supply itself.

2. The unit of power supply is not voltage but power, which refers to the power supply capacity that the power supply can provide.

The power consumption of the two computers is the same, the voltage of the power supply refers to the working voltage of the power supply, the computer consumes 246 watts, then the power supply will only provide 246 watts of power, not 400 watts. 400 refers to the maximum amount of power that a power supply can provide when it is working properly.

It should be the power consumption point of computer B, because the power will be greater than that of A when designed.

When you say 300W or 400W, you mean the actual maximum output power, which is the sum of the maximum power of all accessories in the computer.

You now have a total power of 246W after being tested by 360, so a 300W power supply is sufficient. There is a difference between the maximum output power of the 300W power supply and the 400W power supply, and there is almost no difference in the power consumption of the power supply itself.

The power supply voltage is generally AC 220V (that is, ordinary civil electricity). If the voltage in your area is unstable, it is recommended to buy a wide voltage version of the power supply.

1. You have to find out how you bought this power supply, which is the original from Japan? I still bought it and imported it from Japan.

2. If you buy the original from Japan, then congratulations, a small number of commercial appliances or military power supplies in Japan use NATO DC 110V, while ordinary residents use AC 100V to 200V electricity, while China uses the Warsaw Pact standard AC 220V, and any kind of electrical appliances in Japan cannot be used in China!

3. If it is imported from Japan, the general manufacturer will change the power supply from DC 110V or AC 100V to AC 220V during production, which can be used in China.

4. What is written on your power supply is "100VAC", which means AC voltage 100V, and if it is DC, it should be "DC". Congratulations, you have found a transformer handle and changed the power supply voltage.

You can try it, use it if you can, and throw it away if you can't.

China uses a voltage of 220V, and Japan's voltage should be 100V. Get this straight. Then decide if it can be used.

How did I see Made in China, how did I become Japanese?

The above manual indicates that the input voltage is AC 100V, and the domestic mains voltage is AC 220V, the voltage level is different, and the difference is too much, and it is old, it is best not to use it.

It can be used, but there is no 100V AC here, so it is necessary to configure a transformer and turn 220V into 100V to use. Otherwise, it is easy to burn this power supply.

Only works with 100V power supply, what should you do? It's not cost-effective to bother with remodeling.

As long as there is no fault, it can be used continuously, and the rated 450W belongs to the general power supply. For example, i5 10400F + GTX1660S graphics card.

1All can be VP350P 12V output 336W, 12V output is to power the CPU and graphics card, that is to say, the CPU graphics card does not exceed 336, it is no problem, 560Ti core is 170W, theoretically as long as you have the CPU does not exceed 160, the general low-power CPU 70W, the mainstream 110W.

There are 2 problems though:

The minimum requirement for the system is 500W overall, so your overall power is insufficient.

2.The input voltage range of Antik VP350 is 220V 240V (that is, only 350W in this range), although our mains power is provided by 220V, but it is generally impossible to stabilize the input of 220V, which has a large range, especially the peak power consumption. So with VP350 you have to be equipped with a voltage regulator, that's why it's cheap; Otherwise, the power output of this power supply is extremely unstable.

Therefore, you need to choose a power supply with a core output of more than 500W, which neither refers to the rated power nor the peak power, but refers to the 12V output power. And you need to choose a power supply with a wide voltage input (100V 240V input), otherwise add a voltage regulator. Other than that, you can only change the graphics card.

Not enough, rated 500W recommended TT KK600 strong version.
