How to match the power supply How much power is needed for the hardware on the host I want to build

For general users, as long as 300W is enough, the current CPU is about 60W, the motherboard is 40W, and the graphics card is only about 50W even if it is relatively high-end, plus, hard disk, optical drive, one luck will not exceed 250W. All you need to do is buy one with a maximum power of 300W.

If you have a computer with a dual-core plus a discrete graphics card, it is best to have a peak 350W power supply, and the Huntkey Calm King Diamond Edition is good, 190 yuan.

To determine the power supply power of the host computer, you can answer the following five questions:

1.Look at the power supply label: Power supplies will usually have a label on their enclosure that indicates the power information. The power on the label is expressed in watts (W), for example"500w"or"750w"。This is the most straightforward way to determine the power of the power supply.

2.Reference PC Specifications: PC manufacturers often list the power supply power of the console in their product specifications or manuals. You can consult your computer's user manual or find information about your computer model on the manufacturer's official website**.

These calculators will usually ask you to provide information about your computer's configuration, such as processor model, graphics card model, number of hard drives, etc., and then estimate the power required from this information.

4.Look at the power connectors: Looking at the type and number of power connectors can also give some clues about the power of the power supply. The high-power power supply has more connectors to support more hardware devices, such as high-end graphics cards or multiple hard drives.

5.Consult a professional: If you're still unsure about the power of your power supply or can't find the information, you can consult a computer hardware professional, such as a computer repair technician or salesperson.

They are usually able to provide you with accurate recommendations based on your computer's configuration and needs.

Summary: Determining the power of your PC's main computer can be done by looking at the power supply label, referring to your computer's specifications, using a power supply calculator, observing the power connectors, and consulting with a professional. For accurate results, it is best to combine multiple sources of information to confirm the power supply.

Summary. Kiss, I'm sorry to keep you waiting, I'll help you with this question. The power supply power of a self-assembled computer is calculated as follows:

CPU power + graphics card power + 100), and the final result is taken as the highest integer, that is, the power rating of the power supply that needs to be selected.

Kiss, it's not good to be impulsive, Yin Lafeng has kept you waiting for a long time, I'll help you with this question. The power supply power calculation method of self-assembled computer is: (CPU power + graphics card power + 100), and the final result is taken as the whole number of the highest edge, that is, the power rating of the power supply that needs to be selected.

To put it simply, if you want to choose a power supply, you must know how much power you need to build your computer hardware. Among them, the CPU and graphics card are the two hardware that consume the most power among all hardware. In particular, high-end CPUs and graphics cards consume more than 100W of thermal energy, and the better the performance, the greater the power required.

In particular, Sendan is a mainstream graphics card, and its heat consumption even reaches more than 200W, not to mention some high-performance flagship graphics cards. In addition, such as motherboards, memory modules, hard disks and other hardware devices, they are basically around 50W, which is not very high.

Most of the rated power of ordinary household desktop power supplies will not exceed 400W, and generally around 300W.

If you don't know the power consumption of your computer, you can estimate it yourself according to the model.

You can also use Master Lu to fill in the corresponding model to get the power consumption value.

In addition, if the power consumption of the whole machine is 350W, the required power supply must add a redundancy value, generally at least 20%-25%, that is, the power consumption of 350W power consumption should be configured with a power rated power of at least 400W, preferably 450W.

The total power consumption of the computer (motherboard + CPU + graphics card + memory + hard disk + optical drive + mouse key + other equipment), choose the power supply according to the configuration of your computer, of course, the power supply has a conversion rate, generally about 80%, such as the rated power of 500W, the actual power is about 400W, and the actual power as long as it is greater than the power consumption of all the hardware of your computer, in addition, the power supply still has to choose a reliable brand, stable.

Computer power supply is a device that converts 220V alternating current into direct current and supplies power to computer accessories such as motherboards, drives, graphics cards, etc., which is the hub of power supply for various components of the computer and an important part of the computer. At present, most of the PC power supplies are switching power supplies.

Generally, the power supply is configured according to the actual power of about 70% of the rated power of the power supply, and it should be emphasized here that the rated power is not the maximum power.
