For notebooks, the power of the power supply may be something that people don't care about, but for the performance of the notebook, enough power can keep the computer running at a high level.
At present, the power of 65W is enough for the thin and light, and at least 120W for the game, which is why some games will emphasize the unique power supply technology.
For the game, how much does the power of the power supply have on performance? Let's test it.
This time I chose an i7-8750H processor, a GTX 1060 discrete graphics card and a 16GB memory game. The original power supply is 200W.
In addition to this, I also prepared a 150W power supply with the same interface to test, to see how much impact on performance.
Running test
The first is to use CineBench R15 and 3DMark to see what effect the CPU and graphics card will run. Under the standard 200W power supply, this game's CineBench R15 multi-core running score reaches 1092CB, for i7-8750H Is a very normal level.
When using a 150W power supply, the multi-core running score can only reach 700cb, and the performance is reduced by 36% compared with the standard 200W power supply.

For the GTX 1060 discrete graphics test, I chose 3DMark's Fire Strike Extreme to test. When using 200W power supply, the running score can reach 5497 points, which is also excellent in the same level of GTX 1060.
When using a 150W power supply, the running score can only reach 4540, which is 17% lower than the original power supply, but still much higher than the GTX 1050Ti.
↑↑↑The picture above is 200W. The picture below shows 150W daily use.
In addition to running points, I also tested the number of game frames in Watching Pioneer and the time when the PS imported 100 photos to see how the power of different powers would affect the performance of the computer during actual use. .
The first is the game test of "Watching Pioneer". In the game, the image quality is extremely high. The frame rate is adjusted to 300 and the vertical sync is turned off. The resolution is 1920*1080 and 144Hz refresh rate according to the screen specifications.
↑↑↑The picture above is 200W. The picture below is 150W.
In the course of the game, no matter which power source is used, the game of "Watching Pioneer" is not stuck, but through the record of Fraps, there is still a certain gap in the number of frames.
When using the original 200W power supply, the average number of frames can be maintained at 143 frames. When using a 150W power supply, the average number of frames is only 113 frames, and the average number of frames differs by 30 frames, a reduction of 21%.
↑↑↑The picture above is 200W. The picture below is 150W.
Then use Photoshop to import 100 4K photos to see how long it takes to use different power supplies.
The 200W original power supply takes 1 minute 07 seconds 42 when importing 100 4K photos, and 1 minute 11 seconds 52 when using 150W power supply. Although there is a gap of about 6 seconds, it is considered by the individual to be negligible. Excluding.
to sum up
Through the above tests, it can be found that when using power supplies of different powers, the power of the original power supply can fully exert the full power of the notebook computer, and it is very easy to meet the standard requirements in any situation.
When using a lower power supply, the performance will drop significantly when the notebook is fully loaded, and the gap is not large when the notebook is not fully loaded.
Therefore, in the process of daily use of the notebook, we try to use the original power supply of the notebook. If you have to use a lower power supply when you have to use it, do not have too high requirements for the notebook.
In addition, if the original power supply is lower than the power supply of the same notebook, you can try to change the power of the high power to see if the performance will increase..
