4. What do you think about the power of a desktop computer power supply?

You have a power supply with a maximum output power of 360w. Why are you afraid to change it~

5. Will the actual power of a desktop computer host using a power supply with a smaller power be higher than that of a power supply with a maximum output power of 360w? A more powerful power supply smaller?

What the questioner means is that with the same hardware, if a low-power power supply is used, will the actual power usage of the computer be reduced?

Two people upstairs said that the power supply has the highest efficiency when the load is 50%.

Then first calculate the power of the computer when it is fully loaded. The full load power is X2/80%. This is the power you need to buy a bronze power supply. For gold and platinum power supplies, just change the final dividing percentage.

Is the tripping problem caused by your computer? It is best to test the power of each line in the dormitory yourself to see which line's power suddenly changed too much when it tripped. Pay attention to whether your socket has a ground wire.

6. How powerful is a desktop computer?

(1) The power of mainstream home desktop computers is generally in the range of 50 watts to 400 watts. ; (2) Since current processors, motherboards, and Windows operating systems all have energy-saving mechanisms that will reduce the operating frequency under low loads to save power, the power consumption of all newer desktop computers in the idle state is how much Ten watts, and the full load power consumption will vary greatly depending on the hardware configuration of different performance levels. For example: (1) i3-4130 core display (no independent graphics card), multimedia entertainment and office level. According to data provided by a netizen, the measured power at full load (using OCCT) is 74.56 watts; (2) i3-4130+iGame GTX750Ti , entry-level player level, the measured power at full load is 168.32 watts; (3) i5-4690K+GTX970 STRIX, mid-to-high-end player level, the measured power at full load is 266.71 watts; (4) i7-4770K+iGame980, enthusiast player level, measured at full load The power is 344.10 watts; (3) When selecting a computer host power supply, it cannot be calculated based on the above measured power. The rated power of the power supply should be greater than the configured measured peak power, leaving 25% to 50% redundancy. For example, the actual power is For a 270-watt mainstream gamer-level computer, it is recommended to choose a power supply with a rated power of about 500 watts (no false specifications).

7. What is the rated power and actual power of desktop power supply?

1. The rated power refers to the power of the electrical appliance when it is working normally. Its value is the rated voltage multiplied by the rated current of the electrical appliance. The rated voltage is fixed, with an allowable deviation of 10%.

2. The actual power and actual current of the motor vary with the size of the load being dragged; if the load being dragged is large, the actual power and actual current will be large; if the load being driven is small, the actual power and actual current will be small. .

3. If the actual power and actual current are greater than the rated power and rated current, the motor will overheat and burn; if the actual power and actual current are less than the rated power and rated current, it will cause material waste.

4. Their relationship is, rated power = rated current IN * rated voltage UN * root 3 * power factor, actual power = actual current IN * actual voltage UN * root 3 * power factor.

8. How do you check whether the power of a desktop computer is enough?

A simple way to estimate the required power is to add the TDP of the processor and the TDP of the graphics card and then multiply it by 2. The calculated result is definitely more than enough.

i5 4590 is 84W, GTX750 is 55W. (84+55)×2=278.

Basically, a regular brand 250W power supply is almost enough.

However, the motherboard needs some attention. The motherboards of brand-name machines are all retractable, just enough for use. If the TDP of the original processor is lower than 4590, then the motherboard most likely does not support 4590.
