How many watts does a desktop computer have?

In fact, the electricity used by the computer should be determined by your actual use.

Calculate the power usage time average usage (by maximum usage) CPU 50W * 24 hours * 30%.

Motherboard 20W*24H*100%.

RAM 15W * 24 hours * 100%.

HDD 20W * 24 hours * 100%.

Graphics: 10W * 24 hours * 100%.

Two fans 6W * 24 hours * 100%.

Display 80w * 12 hours * 100%.

NIC 4W * 24 hours * 100%.

Other 10w * 24 hours * 100%.

In this way, it is clear that it is necessary to calculate the use of electricity kilowatt hours for 24 hours.

You can open the case cover.

It's written on your power supply.

Don't be so careful.

Three hours of electricity.

Agree with the upstairs, but it's **,

Generally, the normal operation of the computer is about 300W.

1. The host is generally about 150W (CPU 50-95W, motherboard 25-35W, hard disk 10-15W, memory 10-30W, graphics card 30-100W, sound card 3W, network card 3W optical drive 15-20W, floppy drive 5W).

2. After adding the keyboard and mouse fan, the power consumption of the chassis is about 220W 300W, and then there are CRT monitors and speakers, and the power consumption of a home desktop should be about 350W. The power consumption of the above parts is the maximum power consumption, and not all parts will reach this value in daily use, so the normal operation of the computer is about 300W.

The computer is about 250-400W. The power consumption of a bucket Qingtai computer per month: if it is 300W per hour, 10 hours a day, 30 days a month = 90kW, that is, 90 kWh, this is just a conservative estimate.

Display power consumption: 15-inch, 17-inch, and 19-inch monitors consume about 60W, 80W, and 100W respectively).

The computer also consumes energy in the sleep state, which is inexplicable when it enters standby under Windows XP! It shows that the motherboard is still consuming a lot of power in order to protect the data at this time; Even if the computer is turned off, as long as the plug has not been unplugged, the computer still has energy consumption, about! Things like remote controls and smart switches make appliances easier to use, but they also add an extra energy consumption to appliances – standby energy consumption.

Nowadays, the power consumption of a computer is about 300W. The power consumption mainly depends on the configuration inside.

Take the CPU to calculate the power consumption, which is 65W; There is also a motherboard about 30W; Memory about 10W; Hard disk about 30W; The mainstream graphics card is about 100W; However, it is all full load power consumption, and the standby power consumption is much smaller.

See if you have a discrete graphics card and independent cooling, if there is a suggestion of 600W or more, if there is no 400W enough.

This is the power of the desktop power supply, generally 300-500.
