How to choose a power supply, how to choose a computer power supply

The specifications of the power supply are usually 300W (rated power) 400W (maximum power), which means that the power supply does not usually use the maximum power.

So 300W is enough for ordinary machines, for example, 35W CPU for graphics card, 50W memory for CPU, 15W network card, 5W dual-core CPU is 70W or 100W, this is all based on hardware performance, all add up, generally 200W+, so the power supply rated at 300W is enough.

No, high power, it's all the same, powering up alone is just for the graphics card core to be more stable, improve performance, of course, the power consumption is higher, but for power, there are no big requirements, of course, the interface is not a problem, and the display has a conversion port.

The power supply is enough, use the maximum power of your computer, and then add the power of the accessories you want to upgrade in the future. Of course, you also have to consider factors such as conversion efficiency, noise, etc.

Look at the brand, Haiyun, Kangshu, Delta, PC Power & Cooling, choose one of the four.

Depending on the power you need, the graphics card can be used with an adapter cable, which is not a big problem.

The power mainly depends on the graphics card and whether it is overclocked.

How to choose a computer power supply Hello dear! Office and home: using a processor below the i3 level, using a nuclear graphics card or a discrete graphics card not higher than 1,000 yuan, with low power, it is recommended to use a power supply rated at about 300W.

Game platform: using quad-core processor + no more than 2,000 yuan of independent graphics card, you can play online games and play some large-scale 3D games with low special effects, the power consumption of the whole machine is about 200-300W, it is recommended to choose a rated 450W 650W power supply. Fever host:

i7 level above the processor and more than 2000 yuan independent graphics card, power supply power is recommended to start at 500W, this part of the players are generally experienced DIYER, the power needs to be very clear, more of the quality of the power supply, I believe that similar to the extreme firepower 80plus platinum certification such a power supply can be up to their level. Hope it helps.

I did a rough calculation.,Your ** is close to 7000 yuan.。。。

Actually, you can improve it:

1.The P8Z68-V Gen3 is too expensive, you can change it to the P8Z68-V LE, which is also a large board, and it is no problem to overclock with the i7 2600K. The money saved can be invested in hard drives.

2.The green disk is not suitable for the main disk, and the hard disk is too expensive now, and it is not cost-effective to buy a 2T one. It is recommended that you switch to a 1t green drive, and replace the money saved with the motherboard to a small-capacity SSD.

Use the SSD as the main disk, the system is installed in it, and the green disk is used as the secondary disk, which can greatly improve the boot speed and software running speed, which is faster than you buy an enterprise-level mechanical hard disk. For example, Micron's M4 series.

Finally, let's talk about the power supply, i7 2600K full load 95W, GTX560Ti measured full load power consumption is about 200W, other accessories consume very little power, your host full load power consumption is about 330W, considering overclocking, it is recommended to choose a power supply with a rated power of more than 500W. I recommend a few for your reference, and decide according to your budget:

1.Xianma Black Charm 550, rated 550W, white label efficiency, 360 yuan.

2.Cooler Master GX550, rated 550W, 80PLUS bronze, 480 yuan.

3.Antek Model Zun 520, rated 520W, 80PLUS white label, 460 yuan.

4.Delta NX550, rated 550W, 80PLUS bronze, 550 yuan.

5.Zhenhua overclocking Kingdee 500, rated 500w, 80plus gold, 650 yuan.

You'll need a power supply that's at least rated at 400W.

Recommend SilverStone ST40, **290 or so.

Don't want an Tek 450 on the line I have the same configuration as you The graphics card is better than yours The power supply is good for the big buffalo This depends on personal preference It's cost-effective on the line Your hard drive... Green disk?? Why not a blue disk The green disk is generally used for surveillance video storage.

For example, we use the blue disk, the western blue disk, 500g, and your configuration is about 8500, plus about 1000 monitors, a total of about 8500.
