Power Supply Connectors 電源連接器(P.40)

Learning Objectives 學習目標

• Identify power supply connectors.

   識別電源連接器。

ATX 12V 2.x power supplies connect to the motherboard by way of a 24-pin cable + 4-pin/8-pin for CPU and 6- or 8-pin for PCIe video.

ATX 12V 2.x電源通過24針電纜+ 4針/ 8針（用於CPU）和6或8針（用於PCIe視頻）連接到主板。

The purpose of a "dual-rail" PSU is to separate and limit the current through each wire to avoid overheating.

“雙軌” PSU的目的是分離並限制通過每條電線的電流，以避免過熱。

Originally, the ATX 1.x standard required 20 pins to provide the mainboard (motherboard) power connection. ATX version 2.x expanded this to 24 pins for a standard ATX12V power supply. Many power supplies will provide a 20+4 pin cable, so that they are backward compatible with older systems.

最初，ATX 1.x標準需要20個引腳來提供主板（主板）電源連接。 ATX版本2.x將其擴展為24引腳，用於標準ATX12V電源。 許多電源將提供20 + 4針電纜，以便它們與較早的系統向後兼容。

With the higher voltage requirements of the Pentium 4 and onward, the ATX version 2.x standard made this a 24-pin cable +4 pin (original mini-ATX or P4 connector) or an EPS12 8-pin connector. The ATX12V provides a four-wire square connector for additional motherboard power. ESP12V provides an eight-wire connector (often split into two four-wire connectors for backward compatibility) for additional CPU power. Finally, there is the AUX connector, a six-wire connector to provide older systems with extra power to the motherboard.

隨著奔騰4及更高版本對電壓的更高要求，ATX 2.x版標準將其設置為24針電纜+4針（原始的mini-ATX或P4連接器）或EPS12 8針連接器。 ATX12V提供一個四線方形連接器，用於增加主板電源。 ESP12V提供了一個八線連接器（為了便於向後兼容，通常分為兩個四線連接器），以提供更多的CPU電源。 最後，還有AUX連接器，這是六線連接器，可為較舊的系統提供額外的電源給主板。

ATX12V version 2.x eliminated the 3.3V and 5.5V rails in favor of 12V rails due to the nature of CPU and PCIe power requirements. The ATX standards from version 2.x on have all developed to improve power delivery. The 12V dual-rail PSU is designed to limit over voltage situations and protect against overheating.

Photograph of wires and connectors that leave the power supply and connect it to the motherboard and peripherals.

Power supply wires. 電源線。

In addition to the motherboard needing power to function, peripherals need power to function, too. The power supply provides additional connectors for peripherals used throughout the computer system. The oldest style connector is the Molex connector and is used for PATA hard drives, PATA CD/DVD drives, and extra cooling fans. The Molex is a four-pin connector that is usually one of the largest connectors. A mini-Molex or Berg connector is a four-pin connector that is rather small and only used for floppy disk drives, specifically the 3.5-inch variant of drive. SATA devices use SATA power cables, which are 15-pin L-shaped connectors. PCIe power connectors (peripheral component interconnect express) are six-pin or eight-pin connectors that are used to provide additional power to PCIe video cards at 12 VDC. Finally, if you run out of connectors of a certain type, there are conversion cables to make a Molex into SATA, or Molex into PCIe. Additionally, there exist Y-connectors for Molex that allow a single Molex to be split into two Molex connectors. As you remember, power supplies convert AC to DC power to provide power to the devices. These connectors have either +/-3.3 VDC, +/- 5 VDC, or +/- 12 VDC.

除了主板需要電源才能工作之外，外圍設備也需要電源才能工作。電源為整個計算機系統中使用的外圍設備提供了額外的連接器。最古老的連接器是Molex連接器，用於PATA硬盤驅動器，PATA CD / DVD驅動器和額外的冷卻風扇。 Molex是四針連接器，通常是最大的連接器之一。微型Molex或Berg連接器是一個四針連接器，它很小，僅用於軟盤驅動器，尤其是3.5英寸驅動器。 SATA設備使用SATA電源線，該電源線是15針L形連接器。 PCIe電源連接器（外圍組件互連Express）是六針或八針連接器，用於為12 VDC的PCIe視頻卡提供額外的電源。最後，如果您用完了某種類型的連接器，也可以使用轉換電纜將Molex轉換為SATA，或將Molex轉換為PCIe。此外，還存在用於Molex的Y型連接器，該連接器可將單個Molex分為兩個Molex連接器。您還記得，電源將交流電轉換為直流電，以便為設備供電。這些連接器具有+/- 3.3 VDC，+ /-5 VDC或+/- 12 VDC。
