Which is more powerful computer power supply 115V or 230V?

The power is the same with the same load, and the key is that if you choose 115V, connect it to the mains. The power burned. This selector switch on your power supply is for other countries. For example: Little Japan.

That is, the power supply you buy can be used at home and abroad. Hehe. I digress, to be specific: the load of the power supply is constant. 115V. The current increases. At 230V, the current decreases. But the power remains the same.

115V, high power. Because both 115v and 230v are only used on computers. The voltage and current of the computer are about the same. Then they are inversely proportional. So 115v big.

First of all, we need to make sure that the formula for calculating power is as follows.

Power = Work Time = Voltage * Current = Square of Current * Resistance = Square of Voltage Resistance.

So, if you only determine one quantity, you can't judge the power!

The power of the two is the same, thinking that the power of the computer is certain, and his current is different at different voltages.

It's the same regardless of loss! The premise is the same wide power supply! It is estimated that the owner of the building will ask that voltage level is good! Power depends on two parameters: load current and voltage!

Voltage and power are not the same thing, the product of voltage and current is power.

The algorithm for 115V voltage power lettering is voltage multiplied by current. Power refers to the amount of work done by an object per 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. Answer: The work done per unit time is called power, which is denoted by p.

Output: DC voltage: 12VDC

Rated current: 15A

Rated power: 180W

P=ui power is calculated by formula.

p=w/tp=ui

p=i^2 *r

p=fvp=u^2 /r

The formula for calculating work:

w=fsw=uit

w=i^2 *rt

w=u^2 *t /r

1. The calculation method of the power of two-phase household appliances is:

p = current * voltage * power factor.

For example, 5A current * 220V AC voltage * power factor = 990W1 kWh = 1000W

2. The calculation method of symmetrical three-phase AC household appliance power is:

Active power (W) P = Follow sign 3 * Current * AC voltage * Power factor (COS) Reactive power (VAR) Q = Follow sign 3 * Current * AC voltage * Power factor (Sin) Apparent power (VA) S = Follow sign 3 * Current * AC voltage P indicates power, the unit is "watts", referred to as "watts", and the symbol is "W". w stands for work, the unit is "joules", abbreviated as "joules", and the symbol is "j". t is time, the unit is "seconds", and the symbol is "s".

Since w = f (f force) * s (s distance) (the definition of work), the formula for finding power can also be derived from p = f · v (f is the force and v is the velocity).

The higher the power, the higher the speed, the higher the maximum speed of the car, and the maximum power is often used to describe the power performance of the car. Maximum power is generally expressed in horsepower (ps) or kilowatts (kW), with 1 horsepower equal to kilowatts.

1w=1j/s

The algorithm for 115V voltage power is voltage multiplied by current. Power refers to the amount of work done by an object in the time of a single fissure, that is, power is a physical quantity that describes how fast or slow the 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.

The rated output of the computer power supply is 250W, which will not be the same as the 12V power with a rated output of 370W.

1. After online sampling survey, the output current of the rated output power supply of 250W power supply and +12V voltage group is as follows:

Huntkey Cool King HK350-550P, rated output power 250W, +12V output current 17A,;

Great Wall GW-MATX300

HTPC, rated power 250W, +12V output current 17A;

SEGOTEP nuclear power QPOWER

Power supply, rated power 250W, +12V output current 17A;

2. After inquiry, the 370W capacity power supply is a non-standard product, and the brand power supply of the first-line manufacturers is only rated at 350W, and the sampling of the 350W power supply is as follows:

ANTEC VP-350P power supply, rated power 350W

Dual 12V, output current 18A

x2, marked maximum power 336W;

USCORSAIR VS350 power supply, rated power 350W, single channel 12V, output current 25A, marked maximum power 300W;

Huntkey Jumper 350S, rated at 350W

Dual-channel 12V, loss and defeat current 18A

x2, marked with a maximum power of 312W;

3. Analysis, rated 250W power supply, its 12V voltage group output current is consistent, all are 17A, the maximum output power is 200W. In a group of 350W power supplies, there are single 12V and double 12V, and the total output current is not nearly the same. However, its maximum power is above 300W, which powers the CPU and graphics card.

A power supply is nominal 12V15A, and its output power is 0-180W

The voltage of a power supply is 12 volts, and the current reaches 15A, and its power is 12 15 = 180 watts.

This power supply is rated at about 200W and has a maximum power of 280W.

In actual use, the +12V power is 168W. You can equate it to an ideal 168W power supply.

Are you testing your eyesight? Can you turn on a fill light?

There is no difference in the magnitude 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 is 150W The power cord of the motherboard is a 12-pin split plug, every 6 pins are a plug, there are two, and two of the 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 supply, the smaller the voltage tremor force 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 be more powerful, 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.
