Power issues for power supply Ask a professional to get a good idea

This power is enough, no need to change. But it is better to change to a high-power one, mainly considering the heat of the power supply. If the power supply has been working at full load, the heat will be large, which will affect the service life.

Enough should be enough, but it's a little dangerous, and I'm afraid it's not enough to add some peripherals or something.

You can do the math yourself for reference.

It can be used to run, but the power supply still has to leave a little extra space, the actual power that can be used by the standard 300W is less than 300W, and there is a lot of reactive power loss in the middle. Considering the convenience of i3 and p7h55, it is better to upgrade the power supply with 350W to 400W in the future.

The rated 300W power supply is actually 250W is definitely not enough.

400w is recommended

It's definitely enough, and if it's not enough, it's a short circuit on your computer.

CIS Enterprise Identification System, VIS Visual Recognition System, BIS Behavior Recognition System, and MIS Concept Recognition System.

Please refer to it.

Enough. Mine is also 300w is definitely enough.

The output power of the power supply is the UI.

The total power of the power supply is EI. The output power of the power supply is the UI. The power of the power supply can be divided into:

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

Maximum power: At room temperature, the input voltage is between 200V and 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. Peak power:

The maximum power that a power supply can achieve in a very short period of time can only be maintained for a few seconds to 30 seconds.

Introduction of power supply.

A power supply is a device that converts other forms of energy into electrical energy. Generators can convert mechanical energy into electrical energy, and dry batteries can convert chemical energy into electrical energy. The generator and battery themselves are not electrified, and their poles have positive and negative charges, and the voltage is generated from the positive and negative charges.

When the two poles of the battery are connected to the conductor, the positive and negative charges are released in order to generate current, and when the charge is dissipated, the current (voltage) is eliminated.

Power supply applications: Power supply products are widely used in industrial automation control, scientific research equipment, industrial control equipment, computers and computers, communication equipment, power equipment, instrumentation, medical equipment, semiconductor refrigeration and heating and other fields.

d Correct Set the internal resistance to r and the outer resistance to r The output power is U 2*r (r+r) 2 When r=r, this power is maximum.

The second floor is the correct solution: the power supply is internal, the power supply is composed of two parts, one part of the output, and the other part is consumed by itself, assuming that the voltage of the power supply is u, the internal resistance is r, and the external resistance is r1, then the output power p=r1*[u (r+r1)] 2 According to this formula, it is easy to see that d is correct.

You can also substitute a, b, and c into this formula

Power supply output power: Calculated by the current and voltage of the input load. The total power is equal to the output power plus the loss of the power supply itself.

The power supply has both total power and output power. The total power is all the power provided by the power supply, including the power consumed on the internal resistance and the power consumed on the external circuit (output power). The output power is the power of the external circuit, which is equal to the total power minus the output power.

The total power of the power supply is EI The output power of the power supply is UI (or I 2*R) Output power: P=I 2*R=E 2 (R+R) 2*R=E 2 [(R-R) 2 R+4R] So when R=R, the output power is the maximum, is: Pmax=E 2 (4R).

If you want, you can be infinite without remembering the internal resistance, but generally speaking, the maximum output power of the power supply is the electromotive force e of the power supply, and the equation of the internal resistance r, p=(e 2) r

The total power of the power supply is EI, and the output power of the power supply is UI (or I 2*R) Output power: P=I 2*R=E 2 (R+R) 2*R=E 2 [(R-R) 2 R+4R].

So when r=r, the maximum output power is: pmax=e 2 (4r) power: power refers to the amount of work done by an object in a unit of time, i.e., power is a physical quantity that describes how fast or slow work is done.

The amount of work is constant, and the shorter the time, the greater the power value. The formula for finding power is power = work time. Power is a physical quantity that characterizes the degree of work done fast or slow.

The work done per unit of time is called power and is denoted by p. Therefore, the power is equal to the scalar product of the force and the velocity of the point where the object is stressed.

Output Power: Output power"

nominal

power), also called"Nominal output power"(nominaloutput

power)。

Output power"Explanation in academic literature: For other electrical appliances, nominal power, also known as nominal output power, refers to the maximum value of output power that can work for a long time under the premise that the electrical appliance is not distorted, and the maximum power refers to the maximum value of instantaneous power without damaging the electrical appliance, that is, the maximum load capacity that the electrical appliance can bear. Output power = input power - power of useless work.

12V, the power is 18W.

One kilowatt-hour of electricity is equal to 1 kilowatt-hour.

One hour is kilowatt-hour.

24 hours is the kilowatt-hour of electricity.

24-hour electricity bill, which is equal to two cents.

p=uii, in layman's terms, is that the power is equal to the square of the voltage multiplied by the current.

The voltage and current are indicated above, the voltage is 220V, the current, and the power can be calculated =, 24 hours of power consumption = (132 watts x 24 hours) 1000 = degrees, the daily electricity bill is = yuan = yuan, that is, the electricity cost is about yuan every day.

The hardware is designed with power consumption, for example, GTX1060 6GB is 120 watts, you add up all these powers, and then add 100 watts, and the final result is the rated power of the power supply you need, if there is only a CPU computer, that is, without a graphics card, a power supply rated at 300 watts is enough.

1. All rated 350W means that the maximum output power of the power supply standard is 350W, but it does not mean that he has been working with 350W output, assuming that the hardware used by your computer only consumes 200W, then he works in the output state of 200W, and this 200W is the actual power of your computer.

The overall power consumption of your host can be calculated in this way, 200W divided by the conversion rate of the power supply, for example, if your power conversion rate is 60%, then the power consumption of your host is 333W.

It can be seen that the higher the conversion rate of the power supply, the more energy saving.

According to 200W, because the 350W of your power supply means that this power supply can meet the power consumption of 350W, usually the installation rule is that the system (power supply) must be greater than the consumption system (the overall power consumption of the computer host), otherwise there will be a shortage of supply, the power supply will be burned out due to overload, and other parts of the host may also be broken due to insufficient power supply!

350W is the allowable power consumption within the safety range of the power supply, and 200W is the actual power consumption. That is to say: if you use a 350W power supply with a 5W bulb, the actual power consumption is 5W. Of course, this is only a theoretical algorithm, and the actual power consumption is larger.

Originally, the greater the power supply, the more stable the power can be provided, and the dual-core is generally 300W or more. But honestly, Huntkey Standard Edition (stable 220W, maximum 280W) is good enough for your configuration. **Current (November 2008) RMB 130.

Of course, it is subject to the electrical power consumed by the electrical appliance in actual operation. For example, a child's clothes are not worn by adults; Adult clothes can be worn by children, but it doesn't increase the amount of food just because the clothes are big, haha, image.

200+ but won't be 350w

The theory should be 200, but there should be loss, so 200+ is not 350
