Is the installed power supply universal, and how to choose the installed power supply

It is universal, but it should be noted when installing the machine: for example, if the graphics card and other accessories are better, you need to match a power supply with a slightly higher power. Just look at the input and output power.

The power supply is universal, but the rated power is not the same, you see how much power you need for your machine to choose, not just one can be, but the general business will give you a basic fit, but there will not be much surplus.

is universal. Power supply, in fact, is the least entangled among these three types of hardware, because the development trend of CPU and graphics card is to gradually reduce energy consumption, taking GTX780 as an example, the power supply rated at 500W is enough to drive; On the other hand, the power supply industry is not without progress, the conversion efficiency is gradually improving, the cost and selling price are gradually decreasing, and it will not be too difficult to buy a high-wattage power supply.

Veteran gamers will test and check the 12V current of the power supply to determine whether the power supply is enough to drive the configuration, but in general, we only need to pay attention to the "rated power" of the power supply.

First of all, make sure that your power supply is an ATX power supply, not the kind of power supply from ten years ago.

The important parameter of the power supply is the rated power, and those wires are secondary and can be transferred through the converter.

Power supply, depending on what configuration you use, usually the 200-250W power supply with integrated graphics card configuration is OK, basically any power supply can be used, independent display, 300W power supply can drive 9600GT or 4670 graphics cards below, that is**600 yuan below the graphics card.

The top-level graphics card requires you to configure a sufficient power supply to deal with it, such as GTS260, 4870 or above graphics cards, ** are more than 1,000 yuan, and a minimum power supply of 400W or more is required.

It is not universal, and some motherboard plugs are different, so you must look good when installing them.

Depending on how big the graphics card motherboard you use, you are afraid that it will not be enough, just buy a power supply rated at 400W.

Pay attention to the arch power of the graphics card. Everything else can be plugged in.

Kai this spring to buy a computer power supply to consider how much power the overall computer host needs, and then choose the corresponding power supply. The power consumption is different for different configurations. Choosing a power supply is not only to consider the power parameters of the power supply, but also to look at the evaluation of each benchmark value of the power supply on the evaluation**.

A power supply is a device that converts other forms of energy into electrical energy. The power supply is based on the principle of "magnetic electricity", and generates electricity from renewable energy sources such as hydropower, wind power, ocean tides, dam water pressure difference, solar energy, etc., as well as coal burning and oil residue. Common power sources are dry batteries (direct current) and household 110v-220v ac power supply.
