3. How to accurately calculate the computer power supply? Power supply power calculation formula

Why do we need to accurately calculate computer power supply?

When assembling or purchasing a computer, it is very important to accurately calculate the power supply wattage. The stable operation of a computer is closely related to the matching of power supply. If the power supply is too low, the computer may not work properly or even malfunction. Excessive power will waste energy and increase usage costs.

Power supply power calculation formula

Calculating the power supply power required by the computer is not complicated. You only need to calculate it according to the following formula:

Total power = active power + reactive power + power factor correction coefficient

Among them, the active power is Refers to the energy that a device produces useful work, usually measured in watts (W). Reactive power refers to the energy generated by equipment that is not beneficial to the grid and power supply equipment, and is usually measured in Var (Var). The power factor correction coefficient is a correction coefficient introduced to ensure that the power factor of the entire system is within a reasonable range.

How to obtain active power and reactive power?

To calculate the active power and reactive power of a computer system, you need to understand the power consumption of various hardware devices used by the computer.

Generally speaking, the power consumption information of CPU, graphics card, hard disk, memory and other devices can be found in the device specifications. In addition, you can also obtain approximate values ​​through some online power calculation tools.

Case Analysis

For example, if the CPU power consumption of a computer is 150W, the graphics card power consumption is 200W, the hard disk power consumption is 20W, and the memory power consumption is 10W, then the total active power of this computer is: 150W + 200W + 20W + 10W = 380W.

When calculating reactive power and power factor correction coefficient, it can be evaluated and adjusted according to the actual situation.

How to choose a suitable power supply?

Once the total power of the computer system is calculated, you can choose the appropriate power supply based on this value. Generally speaking, in order to ensure stable power supply, it is best to choose a power supply with a power value slightly higher than the calculated result.

Through the power calculation formula introduced in this article, I believe you can more accurately calculate the power required by the computer system to ensure the stable operation of the computer.

Thank you for reading this article, I hope you can get the help you need.

4. How to calculate the rated power of a computer power supply?

In fact, in a narrow sense, what we mean by whether the power supply is connected or not depends on whether the CPU and graphics card are sufficient, that is, the +12v line. As marked on your power supply, the maximum current of 12v is 16a, that is, the maximum power is 192w, which is enough for 1650s, because 1650s can generally be regarded as about 100w when fully loaded. Of course, at this time, you must also consider your What model is the cpu?

But as a digression, the reliability of the nameplate parameters of such a no-name power supply is still unknown, so it is better to choose a brand power supply as far as possible, at least the reliability is much higher.

5. Ask for help How to calculate how much power a computer needs?

Rough algorithm, required power power = (processor TDP + graphics card TDP) × 2. Just round around the calculated value. If you need to run in the limit state frequently, round up.

TDP is not the actual power consumption, but the "thermal design power consumption" used to calculate the heat dissipation requirements when equipped with a radiator. Under extreme computing conditions, the power consumption of accessories will be slightly higher than TDP. Other components such as memory and hard disk consume very little power and do not require special calculations.

(150+184)×2=668.

For ordinary home use, playing games, etc., 650W is enough. It needs to run professional software. The computer often needs to render complex scenes and work at high intensity for days and nights. 700W is enough.

6. How to calculate the power of computer power supply?

The formula for calculating computer power supply power is: Power = Current × Voltage. Generally, the power of a standard desktop power supply is between 300W and 500W. If you have special needs, such as needing to install more hardware, then you need to calculate the required power based on the actual situation.

First you need to know the power consumption value of each hardware and add them up to get the total power consumption value. The power consumption value of general hardware can be found in its specifications.

Next, you need to consider leaving some margin to deal with some unpredictable situations.

Finally, calculate the power of the power supply based on the total power consumption value.

7. Computer power supply selection?

Depending on the hardware configuration of your computer, a brand power supply rated at 400W will definitely be enough. It's just Delta's NX450 power supply, which uses dual 12V output power supplies. Although its rated power is 450W, its +12V1 output current is only 20A (a reminder, for this kind of power supply with dual +12V output, its +12V1 is used to power the graphics card), so it is paired with GTX1060 For this kind of mid-to-high-end graphics card, there is absolutely no guarantee that it can work stably for a long time. I suggest you take a look at Huntkey JUMPER 450B, Gaming Blade 50 AK450, Cooler Master GX-450W, and FSP Classic PLUS 450W. They all have good performance and can definitely meet the power supply needs of your computer. .

This is the information on the label of the Delta NX450 power supply, you can take a look. In short, this power supply definitely cannot meet the power supply needs of the i5 8500+GTX1060 platform.

Let me show you the nameplate information of several different brands of rated 450W power supplies.

FSP Classic PLUS 450

Nowadays, even the brand power supplies rated at 400W have adopted a single 12V output. For this kind of single-output power supply, its +12 output terminal is used to power the CPU and graphics card at the same time. Therefore, when purchasing a power supply, you must combine the actual power consumption of the CPU and graphics card so that it can Buy a suitable power supply.

The following is the approximate power consumption of the i5 8400+GTX1060 platform when it is fully loaded, you can refer to it. A little reminder, the actual power consumption of different brands of GTX1060 graphics cards is slightly different.
