What are the characteristics of a graphics card that cannot be powered by a power supply?

The characteristics of the power supply that cannot power the graphics card are: 1. The computer does not display directly and there is no sound, but the fans and other equipment will rotate normally, but the computer cannot be turned on; 2. The power supply can drive it slightly, but it cannot be turned on. The system will freeze, or freeze when starting up.

What are the characteristics of the power supply that cannot support the graphics card?

The symptoms of the power supply not being able to power the machine or the graphics card are as follows:

1. There will be no display, no sound, and the fans and other equipment will rotate normally, but it is just like the computer cannot be turned on.

2. The power supply can drive it a little, but the system will freeze when it is turned on, and it may also freeze when starting up.

The computer will black out within a few seconds of booting. If you are lucky enough to force the computer to power on, the graphics card will freeze frequently. If you are unlucky, the power supply, motherboard, and graphics card will all burn if you click the power button.

GTX560SE requires 150W power supply, the standard version requires 200W, and the Ti version requires 220~240W, and they are all concentrated on the 12V branch. The official recommendation is that SE uses a 400W power supply. There is no problem with at least 450W power supply for other versions.

200W of power cannot drive the GTX 560 at all. The 560 requires a rated power of about 400W, at least 350W.

If you force 560 to run, the computer will alarm and the entire machine will not run at all.

Graphics card (Video card, Display card, Graphics card, Video adapter) is one of the basic components of a personal computer. It converts the display information required by the computer system to drive the display. , and provides progressive or interlaced scanning signals to the display to control the correct display of the display. It is an important component connecting the display and the personal computer motherboard. It is one of the important devices of "human machine". Its built-in parallel computing capability is also used at this stage. In operations such as deep learning.

The graphics card is inserted into the expansion slot on the motherboard (usually a PCI-E slot, and previously there were AGP, PCI, ISA and other slots). It is mainly responsible for converting the display signals sent by the host to the monitor into general electrical signals so that the monitor can understand what the personal computer is telling it to do. The graphics card is mainly composed of the graphics card motherboard, display chip, display memory, radiator (heat sink, fan) and other parts. The main chip of the graphics card is called "Video chipset" (also called GPU or VPU, graphics processor or visual processor), which is the main processing unit of the graphics card. The graphics card also has memory similar to computer memory, called "display memory", or video memory for short.

Early graphics cards were simply graphics cards that only played a role in signal conversion; the graphics cards we generally use have 3D screen operations and graphics acceleration functions, so they are also called "graphics accelerator cards" or "3D accelerator card". The earliest graphics cards on the PC were the MDA and CGA 2D accelerator cards installed on the 5150 personal computer launched by IBM in 1981.

Graphics cards usually consist of bus interface, PCB board, display chip, video memory, RAMDAC, VGA BIOS, VGA function pin, D-sub socket and other peripheral components. Most graphics cards also have VGA, DVI display interface or HDMI interface, S-Video terminal and Display Port interface.
