How to choose the power supply for the machine

Integrated graphics card, single-core CPU, 250W power supply, discrete graphics card and single-core CPU need more than 300W.

If your graphics card is 7600 or above and x1600 or above and dual-core CPU, you need to use 350W or 400W or more.

For example, the graphics card is 7900GS, and the CPU is AMD's 3800 dual-core.

Higher configurations generally require a power supply of more than 350W! For example, if the CPU is AM23800+ or above or has a dual-core configuration or above, it is best to use a 350W power supply.

The quality is relatively high, and there are Hangjia Great Wall, which are well-known!

Choose the power supply according to the configuration of the machine

Of course, the brand chooses the big brand!

With the popularity of high-performance and low-power CPUs, and the continuous improvement of the performance of integrated graphics cards and low-end discrete graphics cards, the power consumption of most platforms that can now meet the general application is not high. Generally, low-end machines with integrated graphics cards (one optical drive and one hard disk CPU are not high), you can find a non-miscellaneous power supply on the market.

What about a machine with a discrete graphics card? The PCI-E graphics card sold now, as long as there is no external 6pin power interface, the CPU is not high, and there are 2-3 hard disks, the 300W ones can also be easily handled, and many 250W rated ones can also be handled.

A little fever.,CPU4 cores,It's just a "gentle" little super, just a graphics card, don't do some cow card sli cf and the like, and there is no habit of hanging a string of hard disks, that400W-450W rated power supply is also enough.

What if it's some uncommon configuration? For example, FTP machines have many hard disks. The power consumption of that hard disk is <15W, and the instantaneous current on 12V at the time of booting is calculated, and the power supply requirements of 12V and 5V are 1A, so the estimation is relatively easy to calculate, and the margin is not small.

If the hard disk supports sequential booting, 12V is enough to estimate at 1A.

The choice of power supply first needs to calculate the overall power consumption of your computer, and add 50W on the basis of the overall power consumption, which is the rated power of the power supply you need to choose; Secondly, it is necessary to choose a good brand power supply, such as Antek, Haiyun, Huntkey, Great Wall and other brand power supplies.

It depends on what your configuration is, generally speaking, the mid-range configuration 350W is the mainstream choice, if the price is 4000---6000, the power supply selection is generally 400W to 500W, 6000, generally on 600W, the general situation is like this, the specific situation depends on it.

heat dissipation of accessories, etc.

Let me talk about it, the general CPU and graphics card are 12V power supply, you see how big the power supply is 12V, there are also 12V10A standard 400 watts, and there are also conscience Huntkey 12V17 standard 270 watts, which one will you choose?

This does not mean that the power of the graphics card is 500W, it means that the computer is at least equipped with a power supply of 500W and above, and the power supply is at least 2 6pin graphics card power supply plugs.

When using the computer normally, the hardware will not run at full power, so the 550W power supply can cope with it, and the 550W power supply is not enough when running at full power. It is recommended to use a power supply of more than 600W, and there is a power calculator on the Internet, so you can calculate it yourself.

Corsair CS550M Rated 550W Gold.

Personally, I like the things of the pirate ship, and the quality is also very good, so it is definitely enough to use this.

Personally, I feel that the computer power supply is very important, and I can rest assured that I can buy a ***, although it is a little expensive.

Just buy a *** point power supply, you have a high configuration, and the power is also high.

650W is enough for a desktop computer.

What...

I still use the GIGABYTE GTX660 with 350W, there is no problem at all, it is only 130W when fully loaded... Why do you need such a big power supply?

Overall, the i5 4590 is designed to consume 84W, and the others add up to 35W? Even if it is fully loaded, 20% of the power supply will be lost, and the rated 350W is sufficient. . .

Besides, what games can the landlord have to fully load? Generally speaking, the maximum power consumption is 200W. . . This merchant can really fool people...

450W rated is sufficient...

Computer enthusiasts are welcome to chat.

The power supply of the assembled machine is determined according to its own needs and the power consumption of its own configuration, and the demand refers to overclocking or something. The power consumption is based on different configurations, and the brand must be first-line-based, such as: Huntkey, Zhenhua, Haiyun, Cooler Master, Corsair, TT and the like can be, which disadvantages related to the power supply are:

Power, conversion rate, width, warranty.

The power supply is divided into rated power and peak power, and the power supply should be selected from the rated power.

Like this configuration of lz. 4130 is about 70W, the motherboard is about 8W, the graphics card is less than 100W, 1T is about 7W, and the memory is 4W.

Intel's power consumption is well controlled, the temperature is low and the power is efficient.

Considering the loss, the current configuration LZ selection is absolutely no problem to choose a rated 300W, 300W. Zhenhua Butterfly 300, 12cm large fan, 77% conversion rate, support independent power supply of graphics card, three-year warranty.

There is also Huntkey's Calm King Diamond. TT Veyron 400 or something. The price is generally around 200.

But if you want to upgrade in the future, it's best to consider a 400W one, and you can replace the CPU and graphics card to upgrade in the future.

The price of 400W is around 300. There is not much difference between first-tier brands.
