6. 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.

Huntjia JUMPER 450B

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.

7. How to choose a computer power supply?

Calculate the size of the power supply using special power calculation software, and then multiply the excess by 115%. For example, if the multiplication is 425w, buy a 450w one. If you use AMD graphics card or CPU, it is recommended to add 10%.

As for the brand of power supply, I currently use Haiyun, but Zhenhua is also acceptable. Taiwan’s power supplies are more conscientious and have no love for the mainland.

It is best to have energy consumption certification (80plus), which is divided into white, bronze, silver, gold and platinum.

Load 20% 50% 80%

Conversion rate Conversion rate Conversion rate

White card 80% 80% 80%

Bronze medal 82% 85% 82%

Silver medal 85% 88% 85%

Gold medal 87% 90% 87%

Platinum 90% 94% 91%

I think it’s good for ordinary users to have a white or bronze power supply. For those who are a little more luxurious, they can get a gold power supply. Platinum enthusiasts prefer it.

But don’t be superstitious about the 80plus certification of the power supply. Some manufacturers are very serious about the power supply they send for certification. After obtaining the certification, the mass production is reduced.

So the market price is the ultimate criterion for measuring a power supply. Of course it cannot be the price when being ripped off by JS.

In short, a power supply of 1w/0.8 yuan or more is more reliable, 80plus is more reliable than nothing, and Taiwan’s big brands are more reliable. Also, I am the little tail of Chen Socks upstairs. Because I follow her, I pick a few of the questions she answers that I know how to answer. (๑• . •๑)

8. How much is the appropriate power supply for a computer?

550w or above. Note that it is a standard power supply that is not falsely reported. For example, do you dare to use a 650w power supply that costs more than 100 yuan? The best is 0.7 yuan 1w. For example, a 550w power supply sells for about 385 on Jingdong. It is generally a relatively good power supply. 9. Ask for help in estimating computer power supply? , don’t buy any other brands, I recommend Great Wall, Haiyun, FSP, and Zhenhua. There is no need to pursue gold medals and full modules, the difference is not big
