When buying a computer, many may initially be interested in the diagonal of the monitor, the amount of RAM, hard disk, and video card performance. All this is true, but when choosing a PC, pay attention to one of its most important components - the power supply. The 8 pin adapter for the video card performs the main function - it breathes life into the device. Computer reliability and performance depend on its quality.
What is it?
In most cases, power supplies are included with your laptop or computer. They are installed in a computer case. If the buyer focuses on external PC data, forgetting about the technical specifications, this may lead to the inability to install a more powerful graphics card or additional drive in the future. The main reason may be the lack of connectors.
The main elements of the PC are connected to the power supply. How many devices will be connected to it depends on the number of connectors. Its main task is to supply 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 lightweight, then the power supply is unreliable, and vice versa.
The main elements of a PC are divided into modular and standard. Modular connectors are placed by the manufacturer on the cables. They can be disconnected and attached as needed. For standard units, the connectors are located on cables that cannot be removed. 8 pin - an adapter that is used to connect the central processor. 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
Video cards are powered by connectors built into the device. 8 pin - an adapter that looks like 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 externally similar to each other, the only difference is the presence or absence of auxiliary connectors.
Destination
8 pin - adapter, which was created in order to power the video card located in the computer. The amount of energy consumed by a video card depends on the manufacturer, purpose, series and other parameters. Power fluctuates within wide limits. 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, the power of other elements in the computer depends on it. It provides maximum PC performance.
How to connect?
If the motherboard in a computer or laptop is demanding, then 8 pin is an adapter that will provide proper power to the processor. In the absence of an eight-pin connector, a removable connector will help. Some users of outdated PCs and modern video cards may encounter the presence of an eight-pin connector on the card and its absence on the power supply. The plus is that 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 an error occurs when starting the system, this 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 cable has an eight-pin connector on the one hand, and two interfaces on the other. This allows you to connect an additional GPU and not buy a new power supply. Such an adapter is necessary if the equipment needs updating or installation. The cost of an eight-pin cable is more than democratic and starts at 40 rubles.
Features
The 8 pin power adapter is a fairly powerful type of connector that is used for demanding graphics cards. It supplies the computer with additional power of 150 watts. In a modern video card, the unit must be provided with a power connector. Additional connectors may indicate that the video card requires a lot of energy to work. 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 unpretentious video cards without additional connectors with low performance.
The number of slots on the video card can help calculate how much power will be consumed. If the video card has several connectors, normal operation will be ensured by a power cable, which should be connected to each connector. This will ensure normal PC operation and good performance. If the video card has 8 pin, 6 pin, it can receive energy of 300 watts. Users may come across power supplies that share lines. Each connector will receive energy through its own channel. Experts advise when choosing a computer to pay attention to the types of connectors, if you do not want to face low performance and lack of power in the future.
disadvantages
An 8 pin adapter for a video card performs a specific task. There can be no actual flaws in the connector, because this is one of the components of the computer. The flow of energy and power to the elements of the device depend on it. The quality of the connectors, as well as other parts, depends on the manufacturer, materials and assembly methods.
When choosing a removable adapter, consider its purpose, type of equipment, connectors on the device, cable length, compatibility, weight, packaging. The life of the adapter and the performance of the computer will depend on the quality of the adapter. Buy a strong cable, also pay attention to wires, fastenings. There should not be chips, cracks and other defects.
