How many watts of power is best used for such a configuration

The recommended minimum wattage consumption is: 250 watts.

However, the power conversion rate has not yet been calculated

Rated power supply * 80% = power supply used by the computer (some power is converted to heat energy and dissipated).

250w divided by 312w

Then use a minimum of 300W power supply

Of course, the use of 200W power supply can also drive the computer.,But when it's fully loaded, it crashes.。。 And using too little power hurts the hard drive (the power supply is the number one killer of hard drives).

I recommend using a 300w power supply.

Great Wall Huntkey is a well-known brand and trustworthy

Huntkey Calm King Diamond Version 210 Yuan 12cm Fan Structure Quiet to use

You can take a look. Xianma Chaoying 450 200 yuan or so 2009 Zhongguancun recommended products 350w

There is no generation of hard disks, but they are divided into types according to the interface of the hard disk and the mode of operation. For example, disks, solid state drives. IDE-style interface, SATA-style interface, etc.

According to the cache division: 8m, 16m, 32mSize division:

3-inch plate, 5-inch plate. Rotational speed division. Too much.

Most of the 160g ones are in a dual-disc structure, which is slower than a single-disc operation. I'll use my plate and let others do the talking

Question added: There are very few incompatibilities now. Rest assured.

After all, low-end products are still Spartak's cost-effective point. Many of ASUS's low-end products are OEM production, I hope it can help you.

LZ can go to Zhongguancun to see, Spartak B (Zhongguancun recommended products, star evaluation, dare to ask if there is such a high evaluation of the 499 yuan motherboard

LZ can find a "power supply power calculator" on the Internet to calculate it by itself

Motherboard: about 20W

Processor: Approx. 70W

Graphics card: Approx. 35W

Memory: about 10W

Main hard disk: about 10W

There are also optical drives, etc., which require 50W

Just use a 250W power supply.

With a rated 300W, it can be stable, and I think the Great Wall is the highest in terms of cost performance, at more than 100 points.

Hard disk Your hard disk is several years ago It can be used but the performance is too poor Now the mainstream ones are 500g 335 Seagate 12th generation is good 500g single disc speed king cost-effective.

Rated at 350W or 400W.

100 dollars less, buy a cheap power supply, and then the CPU memory and stuff burn out, that's your thing.

300W rating is enough, I don't know how many generations the hard drive is. Can be plugged in.

Xianma Chaoying 450 (ATX-330-3).

Power Type: Desktop Rated Power: 350W

You can still buy a 160g hard drive??? The cache size is only 8M, and your configuration is not suitable for this hard disk.

The amount of power that a desktop computer power supply is suitable for depends mainly on the sum of the power consumption of all the hardware, and then some power space is appropriately relaxed for overclocking or upgrading backup.

As long as you grasp the maximum power consumption of the two main power consumers of CPU and graphics card, the power consumption of the motherboard, memory, hard disk, etc. is small, and the sum is generally not more than the power consumption, the power consumption of entry-level and mainstream-level CPUs is about 70W, while the high-end CPU is about 100W, and the power consumption of entry-level and thousand-yuan graphics cards is calculated according to 100W and 150W respectively.

Through the above methods, it is very easy to calculate how much W power supply to buy for installation, for example, Intel ninth-generation mainstream i5-9400F+GTX1660Ti, then you need other hardware 50W + mainstream processor 70W + mainstream graphics card 170W + plus 100W, about 390W, generally choose 400W-450W is enough, and there is no power supply power of independent graphics card, the power consumption is basically about 200W, and it is enough to buy 300W power supply.
