8 pin - adapter for video card. Description, purpose, connection

When buying a computer, many may initially be interested in the monitor's diagonal, the amount of RAM, the hard drive, the performance of the video card. All this is true, but choosing a PC, pay attention to one of its most important components - the power unit. The 8 pin adapter for video card performs the main function - it breathes life into the device. Its reliability depends on the reliability of the computer and performance.

What is it?

In most cases, power supplies come with a laptop or computer. They can be installed in a computer case. If the buyer is guided by the external data of the PC, forgetting about the technical characteristics, this can lead to the impossibility of installing a more powerful video card or an additional drive in the future. The main reason may be a lack of connectors for connection.

The main elements of the PC are connected to the power supply unit. The number of connectors determines how many devices will be connected to it. Its main task is the supply of energy to the processor, memory, video card, hard drive and other elements. The power reserve of the power supply allows it to work in optimal conditions without overloads. Today on sale you can find blocks of various capacities (from 150 to 1500 watts). The average power range of the unit to be followed is 450 watts. When buying a laptop, evaluate its weight. If the device is light, the power supply is unreliable, and vice versa.

The main elements of the PC are divided into modular and standard. Modular connectors are placed by the manufacturer on the cables. They can be detached and connected as necessary. For standard units, the connectors are located on cables that are not removed. The 8 pin adapter is used to connect the CPU. Many motherboards have a 4 pin connector. Often the eight consists of two fours. There are also 15 pin, 8 pin, 6 pin connectors.

Appearance

Power video cards are provided by means of connectors built into the case of the device. 8 pin - an adapter, similar to a cord, on one side of which there are eight connectors, and on the other - connecting elements. Fixed adapter - built-in. It has eight connectors arranged in two rows (four in each).

Other models are similar in appearance, the difference is only in the presence or absence of auxiliary connectors.

Purpose

8 pin - adapter, which is designed to power a graphics card located in the computer. The amount of energy consumption of the video card depends on the manufacturer, purpose, series and other parameters. Power varies widely. To provide power to the video card and other components, the device will need sources. The most common are PCIe x16, 6 pin, 8 pin. The adapter is needed not only for the video card, it depends on the power of other elements in the computer. It provides maximum PC performance.

How to connect?

If the motherboard in the computer or laptop is demanding, then the 8 pin adapter is the one that will ensure proper power to the processor. If there is no 8-pin connector, a removable connector will help. Some users of obsolete PCs and modern video cards may encounter the presence of an eight-pin connector on the card and its absence on the power supply. In addition, the 8 pin consists of six connectors, which have two additional contacts. This is necessary in order to give the video card additional power. It is advisable to use all eight connectors on the adapter, but this is not a strict rule.

If you receive an error when starting the system, it means that the video adapter does not have enough power, and you need to connect the corresponding connector to the power supply. The Molex 8 pin adapter is designed to power the graphics card. The loop has an eight-pin connector on one side, and on the other two interfaces. This allows you to connect an additional GPU and not buy a new power supply. Such an adapter is required if the equipment requires an upgrade or installation. The cost of an eight-pin loop is more than democratic and starts at 40 rubles.

Features

The 8 pin power adapter is a rather powerful type of connector that is used for demanding video cards. It delivers to the computer elements an additional power of 150 watts. A modern video card should be provided with a power connector. Additional connectors may indicate that the video card is required to work a lot of energy. This also indicates a high performance PC or laptop. Modern graphics cards are powered by a motherboard connector that delivers power up to 75 watts. This is enough for unassuming graphics cards without additional connectors with low performance.

The number of connectors on the video card can help calculate how much energy will be consumed. If the video card has several connectors, the normal power supply will be provided by the power cable, which should be connected to each connector. This will ensure the normal operation of the PC and good performance. If the video card has 8 pin, 6 pin, it can receive power of 300 watts. Users can meet power supplies in which the lines are separated. Each connector will receive power on its own channel. Experts advise when choosing a computer to pay attention to the types of connectors, if you do not want to face in the future with low performance and lack of power.

disadvantages

The 8 pin adapter for a video card performs a certain task. Actual disadvantages of the connector can not be, because this is one of the components of the computer. It depends on the supply of energy and food elements of the device. The quality of connectors, as well as other parts, depends on the manufacturer, materials and methods of assembly.

When choosing a removable adapter, consider its purpose, type of equipment, connectors on the device, cable length, compatibility, weight, packaging. The quality of the adapter will depend on its service life, computer performance. Buy a strong cable, also pay attention to wires, fasteners. There should be no chips, cracks and other marriages.
