It's best to change the power supply, it is recommended to use a 350W one, 300W is also enough!

200w is not enough, more than 300w is OK. If you want to overclock, it is best to configure 350W or more.

It is recommended to update the Great Wall 450W power supply, more than 100 RMB, the performance is good, not expensive and durable.

If you have the money, why don't you switch to a turbo-electric power supply? Hehe, it seems that you are going to generate electricity for the Three Gorges!

It's enough, unless you want to make the machine very smooth, without the slightest problem, if you don't change it, you can do it! Buy it again if you burn it!

Go to Huntkey's homepage to check it out!! This is the clearest thing to do!!

It's dangerous, it's a bit dangerous not to overclock, it's best to change to a 350W Huntkey.

If you are planning to overclock, it is best to use a power supply of more than 300W, and if possible, use a 400W one.

The rated power is the power that the power supply can continue to work with, that is, the ability of the power supply to continue to the computer under normal conditions.

The maximum power is the power that the power supply can achieve desperately, which is not sustainable and meaningless.

The conversion rate is that your home appliance meter has turned 10 kWh, and the computer has 9 kWh, so the efficiency is 90%.

Version This is mainly to adapt to the new motherboard, the new motherboard has a lot more things than before, so the power supply should be improved, such as a few more wires, etc., this can buy the latest version of the power supply, of course, the latest power supply also supports the old motherboard, not the other way.

Your 200W hardware, leave room for upgrades, with a 350W power supply is more than enough.

The power supply will age, which is reflected in the fact that the loss itself becomes larger, the fan noise is louder, and the efficiency is lower, but it is generally fine, as long as it is not broken, then continue to use.

The rated power of the power supply is not the maximum power, and the maximum power is the instantaneous peak. If you don't want to upgrade the power supply, 250W, it's fine.

Landlord, your situation should be the problem of the contact of the power part.

For a few questions you said:

1. The excess wire can be removed - even if you don't remove it and don't connect any equipment, it is still unloaded, that is, it is like this with or without it. This can be viewed from the Great Wall power supply from a long time ago.

2. It can be soldered directly on the circuit board. However, if the power supply fails, it is very troublesome to replace. It's not very pretty.

3. It is possible to use heat shrinkable tubes. A lot of engineering prototypes do just that.

4. For the difference, in my opinion, there are basically two: one is not very beautiful, and the other is that things are broken and maintenance is very troublesome.

I hope the above is helpful to the landlord.

1. Absolutely.

2. Yes, but it is not necessary, it is not connected to be unloaded.

3. It does not affect.

The difference between 4, 2 and 3 is just the difference in the position where you cut the ** cable.

5. You have to make sure that the old power supply itself is normal, and you are absolutely wrong to cut the cable - isn't it more convenient to cut out the iron sheet of the wire opening?

If there is less wire, it may loosen when you move the wire.

The power supply is to supply power rather than consume electricity, and the function of the power supply is to convert 220V AC power into 12V, 5V, and DC power required for computer accessories. So the power supply is like the human heart, which is very important.

350W power supply, which means that the power supply can support a maximum output of 350W power. It doesn't mean that the power is 350W

How much electricity is used depends on two things. The first is host power consumption, and the second is power conversion efficiency. The first point is easy to understand, different CPUs, graphics cards and other accessories have different power consumption, different host load conditions, and different power required by accessories.

The second point, as mentioned earlier, the power supply is a conversion process, and there must be losses in this process, and the conversion efficiency of a good power supply is generally more than 80%, and this efficiency value will also change with the load rate of the power supply.

It's easy to understand with your example. The total power of computer accessories is 200W, the power supply is 350W, and the load rate is about 60%, which is the highest power efficiency range, and the better power supply can reach about 85% efficiency. So the maximum power consumption of this machine is about 235W.

Of course, computers are not running at full capacity at all times, and they often fall below the maximum power consumption (such as 200W above), and the idle power of today's machines is generally only about W.

This is a very deep question. I don't really understand. However, three hundred and five entry computers are generally enough.

I used four hundred and five.

Generally, it is powered according to the requirements of your computer.,Mine is 750W.,If you supply power according to the power supply rating, I pay the electricity bill.。。 I can't use more than 300W on my computer.

The power supply is based on the actual power consumption output of your computer configuration, but the high-power power output is stable and strong, and at the same time, it is a little higher than the low-power, which can be ignored, and the power supply is convenient to upgrade the graphics card CPU in the future, and the general configuration is rated high50W.

The power consumption of the host is not determined by the power rating of the power supply, but by the power consumption of the host accessories. If your host consumes 200W at full load, even if you install a power supply rated at 350W, it will still consume 200W at full load, instead of the power supply rated at 350W. In addition, the computer consumes very little power when it is standby, generally only a few tens of watts.

It is worth studying these documents for you.

The power consumption of your entire platform does not exceed 300W

Antik BP-430PLUS 290 430W , with you this set of configurations is completely sufficient.

International first-line brand, excellent quality, and domestic incomparable.

It is recommended to choose the Great Wall power supply, and the Great Wall 400w quad-core king should be no problem.

The Black Knight 450 is rated at 450W, and the power is enough for you to put on the HDD + SSD.

FSP's power supply is basically nothing to say, the brand and quality can be The key is that this cost performance is really good, rated at 450w**, in the early 300s, very good.
