Question: How to identify the 8pin power connector of the graphics card? Introduction: The graphics card is an important component in the computer responsible for image processing, and the 8pin power interface is the key to providing stable power to the graphics card. This article will introduce in detail the definition and usage of the 8pin power interface of the graphics card to help you easily identify and correctly connect the graphics card power supply.
1. How to define the 8pin power interface of the graphics card?
The 8pin power interface of the graphics card is an interface used for power supply and is usually used for high-performance graphics cards. It has 8 pins, 6 of which are used to provide power and the other two are used for communication and control signals. This interface is defined by PCI-SIG (Peripheral Component Interconnect Special Interest Group) and is widely used in modern computers and game consoles. Using the 8pin interface can provide a more stable and reliable power supply, helping the graphics card to perform better. At the same time, the 8pin interface also has the compatibility of the 6pin interface, so it can be compatible with old power supplies and graphics cards.
2. How to connect the power interface to the 8pin graphics card?
The graphics card interface is generally 6PIN/8pin (6+2) or dual 6pin or dual 8pin. The CPU power supply on the motherboard is 4+4PIN. Connect the power supply to 8PIN (6+2PIN). Push the 2PIN interface forward by hand, and you can turn it into a 6PIN interface and plug it into the 6PIN graphics card interface to use
3. The 8pin graphics card power interface only has 7 pins?
The power interface of the 8-pin graphics card only has 7 pins, which is normal. One of them is a positioning hole. The graphics card power supply has eight holes and seven pins. One of them is a positioning hole. Plug in the 8 pn power supply directly. Just do it
4. What does the graphics card power interface 2*8pin mean?
The graphics card power interface 2*8pin means one line. This is an 8pin graphics card power cord. Generally speaking, there is no separate 8pin, it is all derived from 6pin and 2pin. Because it is practical, it can be used as 6pin or 8pin.
5. What is the difference between 6pin and 8pin graphics card power interface?
1. The number of phases is different: 6pin means six-phase power supply, and 8pin means eight-phase power supply. Multi-phase power supply does not simply connect components in parallel, but also staggers their working times on the basis of parallel connection. The phase in the multi-phase power supply is the phase of the PWM signal wave. Multi-phase power supply does not simply connect components in parallel, but also staggers their working times on the basis of parallel connection.
2. Different currents: dual 6Pin can withstand higher current than single 8Pin. The stability is only related to the power supply. If the power supply output voltage is stable, the graphics card will be stable.
It is rare to see a single 8-pin graphics card, most of them are single 6-pin~dual 6-pin~6+8pin+dual 8-pin.
The main reason is that most power supplies have a single 6-pin graphics card power supply interface, and the entire single 8-pin graphics card is better than most power supplies.
3. Different stability: 6PIN can be plugged into 8PIN. However, when the graphics card is running under high load, the frequency may not be able to reach the highest frequency due to insufficient power supply. You can directly plug in 8pin, and then use double 4pin to 6pin. Adapter, convert two large 4pins into 6pins and plug them into the graphics card.
6. Which graphics card power interface is better, 8pin or 6pin?
If it is a graphics card with the same core, the 6-pin one should be more energy-efficient and have lower power consumption and heat generation. The performance of 8pin should be slightly stronger.
Computer graphics card 6pin power supply and 8pin power supply have different power supply capabilities. The 6PIN power supply is 72W, while the 8PIN power supply is 96W.
The specific differences are:
1. Different number of phases: 6pin means six-phase power supply, and 8pin means eight-phase power supply. Multi-phase power supply does not simply connect components in parallel, but also staggers their working times on the basis of parallel connection. The phase in the multi-phase power supply is the phase of the PWM signal wave. Multi-phase power supply does not simply connect components in parallel, but also staggers their working times on the basis of parallel connection.
2. Different currents: dual 6Pin can withstand higher current than single 8Pin. The stability is only related to the power supply. If the power supply output voltage is stable, the graphics card will be stable.
It is rare to see a single 8-pin graphics card, most of them are single 6-pin~dual 6-pin~6+8pin+dual 8-pin.
The main reason is that most power supplies have a single 6-pin graphics card power supply interface, and the entire single 8-pin graphics card is better than most power supplies.
3. Different stability: 6PIN can be plugged into 8PIN. However, when the graphics card is running under high load, the frequency may not be able to reach the highest frequency due to insufficient power supply. You can directly plug in 8pin, and then use double 4pin to 6pin. Adapter, convert two large 4pins into 6pins and plug them into the graphics card.
7. How to connect the 8pin power interface to the 4pin motherboard?
The 8PIN power supply interface is composed of two 4pin power supply interfaces, so it can be used directly by connecting one of the 4pin power supply interfaces without affecting the normal operation of the CPU.
8. When the CPU power interface is plugged into 8pin and 4pin is plugged in, the screen goes black at startup?
The CPU motherboard socket is 8pin, and the power plug is 4pin. Motherboards with 8pin CPU power supply socket design are mostly overclocking motherboards or high-end motherboards, which enhance the power supply interface carrying capacity and provide stable overclocking current. In fact, 8pin is just 4pin+4pin with an extra set of 12 power supplies. In physics, it is just 2 lines to share the current. Reduce line heating. The power consumption of ordinary household CPUs is not large, basically below 100w. There is no problem without overclocking with a single 4Pin interface, and a single 4Pin interface is sufficient.
9. グラフィックス カードの 8 ピン電源インターフェイスはマザーボード上の CPU の電源インターフェイスと同じですか?
ビデオ カードは通常 6PIN または 6PIN+6PIN です。グラフィック カードが 8PIN の場合は問題ありません。一方の端は電源用の 4PIN です。たぶん6+2です。これはグラフィックカード用です。現在の電源はすべて 20+4 または 24+4、24+8 です。電源を購入する場合は、安定していて十分な定格電力を持つものを選択してください。インターフェイスがすべて同じ4PINだからです。
10. コンピューターの電源インターフェースについて?
こんにちは、ご質問に喜んでお答えいたします。
電源のメイン出力インターフェイスとは、電源によってマザーボード、グラフィックス カード、ハードディスク、光学ドライブ、フロッピー ドライブ、およびその他のデバイスに提供される電源インターフェイスを指します。
1 つ目は、マザーボードの主電源インターフェースです。以前は、マザーボードの主電源インターフェースは 20 ピンでしたが、ATX 12V 2.0 仕様から、多くのマザーボードが使用されるようになりました。明らかに、24 ピンのメイン電源インターフェイスにピン接続された電源を備えたマザーボードを購入する方が適しています。
もちろん、電源の下位互換性の問題を解決するために、ほとんどの 2.0 電源のメイン電源インターフェイスは「セパレート」設計を採用するか、24Pin → 20Pin 変換コネクタが付属します。この設計は非常に配慮されています。
さらに、多くのコンピューターは SATA ハード ドライブを使用していますが、古いハード ドライブとほとんどの光学式ドライブには依然として従来の「D」タイプの電源インターフェイスが搭載されているため、購入オプションには複数の SATA デバイスの電源インターフェイスがあり、" D" タイプ電源インターフェースを同時に使用可能。電源にアダプターを追加する必要はありません。
多くのマザーボードでは、主電源インターフェイスに加えて、4 ピンまたは 8 ピンの独立した電源インターフェイスも必要になる場合があります。これは通常、CPU に補助電源を供給するために使用されます。また、多くの電力を消費する一部の PCI-Express グラフィックス カードには、6 ピンの補助電源インターフェイスも必要になる場合があります。2 つのグラフィックス カードを搭載したコンピューターの場合は、2 つの 6 ピンの補助電源インターフェイスが必要になる場合があります。
電源はコンピューターの心臓部であり、コンピューターを安定して動作させるためのエネルギーを継続的に供給します。主に、すべての電源にある出力ワイヤについて説明します。位置が異なる電源は、出力線の本数は異なりますが、黄色、赤、オレンジ、紫、青、白、灰色、緑、黒の9色のカラフルな色と切り離すことはできません。サウンド PC の電源にはすべてこの 9 色のワイヤーが付いています (現在主流の電源には白いワイヤーが省略されています)。ハードウェアの観点からコンピューターを学び始めたばかりの多くの友人は、その具体的な機能についてまだ混乱していると思います。立ち上がって見てください。
コンピュータ電源 20 ピン インターフェイス、電源 24 ピン インターフェイス
黄色: +12V
黄色の線は、電源で最も多くある必要があります。 CPU や PCI-E グラフィックス カードの電源コンポーネントに加えて、+12V の役割も電源において重要な役割を果たします。
+12V は常に、ハード ドライブ、光学ドライブ、フロッピー ドライブのスピンドル モーターとシーク モーターに電力を供給するとともに、ISA スロットに動作電圧を供給し、シリアル ポート デバイスなどの回路にロジック信号レベルを供給してきました。 +12V 電圧出力に異常があると、ハードドライブ、光学ドライブ、フロッピードライブのディスク読み取り性能が不安定になることがよくあります。電圧が低いと、光学ドライブがディスクを深刻に認識し、ハードディスクの論理不良セクタが頻繁に発生し、システムがクラッシュしやすくなり、正常に使用できなくなります。高速側にあると、光学式ドライブの速度が高すぎるため、コントロールを失ってクラッシュしたり、ハードディスクが停止したり回転したりする可能性が高くなります。現時点では、+12V 電源が不足すると、PCI-E グラフィックス カードのパフォーマンスに直接影響し、CPU に影響を及ぼし、クラッシュを直接引き起こします。
青: -12V
-12V の電圧は、シリアル ポートのロジック判定レベルを提供するためのもので、必要な電流は大きくなく、電圧偏差が大きすぎても、通常は 1A 未満です。論理レベルの 0 レベルは -3V ~ -15V の広い範囲を持つため、フォールトは発生しません。
赤: +5V
+5V 配線の数は黄色の配線と同じです +5V 電源は、CPU や PCI などの集積回路に供給される動作電圧です。 、AGP、ISA など、コンピュータの主電源です。現在、すべての CPU は +12V と +5V の混合電源を使用しており、その要件は以前ほど高くありません。ただ、最新のIntel ATX12V 2.2バージョンでは+5V電源供給能力が強化され、デュアルコアCPUへの電源供給が強化されました。電源の品質は、コンピュータのシステムの安定性に直接関係します。
白: -5V
現在、白線の電源は非常に少なく、ロジック回路の判定レベルとしても使用できます。システムの通常の動作には影響を与えず、基本的には必要ありません。
