Does the more power the power adapter consumes?

1. Is the power insufficient?

If the power of the computer is insufficient, the computer is prone to automatic shutdown and restart or can not be started or run large software or games often restart the problem. So in the choice of PC power supply, generally larger than the demand for power but not a lot. The idea is to leave enough room for subsequent hardware upgrades so that you don't have to replace the power supply every time you upgrade.

Under normal circumstances, the entry-level computer power is less than 200W, so with the rated power of 300W power supply, of course, you can also use four or five hundred watts of power supply, just spend some money and can not play any role, and 300W power basically no difference.

2. More power consumes more electricity?

If the computer power is greater, the more electricity consumption, but simply increase the rated power of the PC power supply, the use of electricity will not change. How much the computer needs, the PC power will provide how much, everything to the whole, the power itself will also consume a part of the power, but there is not much impact.

The power consumption of the computer host should be calculated by the power used when all the hardware is working. The greater the power, the greater the power of the load. It can support more hardware to work at the same time or support the stable operation of some hardware when the load is full.

As for the power consumption of the computer using different power does exist computer power consumption is different, if you want to reduce the power consumption of the computer, you can choose 80 PLUS certification of power conversion efficiency is higher, relatively speaking can save a little power but not a lot, on the computer to talk about power saving is meaningless.

When we buy power must reserve a certain power space to ensure the stable operation of the computer, especially like memory, graphics card, CPU overclocking players, must be the power to relax some. And the trouble caused by the power supply is no doubt that the power is not enough to use the computer normally, there will be no sign of computer restart. And if the power supply is not enough, it is easy to appear full load, the longer the power supply is used under full load, the more likely it is to burn out.
