Introduction

Hi and welcome to the PC Connectors Pin-Outs ebook. I hope you are reading this book because you are searching for any one of the connector’s Pin Diagram or Pin Out of your PC. If yes, this is the book where you will get all the Pin-Outs of all the connectors in one neat book. So, you don’t have to search for each and every connector in the internet and waste your time. I will try to update this ebook whenever new connectors comes into the market, such as the USB 3.0 - SuperSpeed, which has been given in this ebook. I have not given the PCI, PCI-E and AGP Slots, because it has many pins and has a large description. So, please search for these slots yourself in the internet. This ebook has been created using MiKTeX - LATEX, for Microsoftr Windows, WinShell, LaTeX Editor and InkScape, Vector Graphics Editor. I have made all efforts to use Vector Graphics for very good clarity for printing.

Power Supply Connectors

2.1

ATX 20/24-pin Power Supply Connector

The ATX specification requires the power supply to produce three main outputs, +3.3 V, +5 V and +12 V. Low-power -12 V and 5 VSB (standby) supplies are also required. A -5 V output was originally required, but it is now completely obsolete. Originally the motherboard was powered by one 20-pin connector. An ATX power supply provides a number of peripheral power connectors, and (in modern systems) two connectors for the motherboard: a 4-pin auxiliary connector providing additional power to the CPU, and a main 24-pin power supply connector, an extension of the original 20-pin version. See figure 1 for 24-pin ATX power connector.

24-pin ATX12V 2.x Power Supply Connector (20-pins omits the last 4: 11, 12, 23 and 24)

Figure 1: 24-pin ATX 2.x power supply connector Four wires have special functions: 1. PS ON# or ”Power On” is a signal from the motherboard to the power supply. When the line is connected to GND (by the motherboard), the

Personal Computer (PC) Conectors Pin Outs and Pin Diagrams 2 POWER SUPPLY CONNECTORS

power supply turns on. It is internally pulled up to +5 V inside the power supply. 2. PWR OK or ”Power Good” is an output from the power supply that indicates that its output has stabilized and is ready for use. It remains low for a brief time (100–500 ms) after the PS ON# signal is pulled low. 3. +5 VSB or ”+5 V standby” supplies power even when the rest of the supply lines are off. This can be used to power the circuitry that controls the Power On signal. 4. +3.3 V sense should be connected to the +3.3 V on the motherboard or its power connector. This connection allows for remote sensing of the voltage drop in the power supply wiring.

Notes: 1. Pins 3,7,13 are pre-charge. Pin 11 may be used for other purposes than GND. 2. Pins 1, 2, and 3 are optional as well, as evidenced by some adapter cables that connect the drives to older PSUs. These are usually Yadapters that have the four-pin drive connector on the other end.

Floppy Connector

Figure 7 shows the 3.5 inch Floppy Connector at the motherboard.

Figure 7: Floppy connector Notes: 1. The original floppy cable required that each drive was jumpered to the right ID. But IBM come up with an idea to avoid jumpering the floppies. 2. If wire 10-16 are twisted before the last connector the jumpering is avoided. Each drive should be jumpered to act as Drive 2. If only one drive is used then leave the middle connector free.

CPU and System FAN Connector

Figure 8 shows the new 4-pin CPU Fan connector at the Motherboard. Notes: 1. Colors may change. 2. Chassis and CPU fans may use either 3-pin or 4-pin power connectors. 3-pin connectors are usually used for the smaller chassis fans with lower power consumption. 4-pin connectors are usually used by CPU fans with higher power consumption. Fans and on-board fan headers are backwards compatible.

3. When using a 3-pin power connector with a 4-pin fan header, the fan will always be on; there is no fan control. Proper fan connector placement is shown in the figures below:  Fan has a 3-pin power connector; desktop board has a 4-pin fan header:  Fan has a 4-pin power connector; desktop board has a 3-pin fan header:

Figure 13: Parallel Port Connector Basically, the PC Parallel (LPT) Port has it’s own address. Usually, nowadays we are having only one LPT port and it’s address happens to be ’378’ in Hexadecimal, which is known as the Data Port also called as the Base Address. The same Parallel Port also has two more addresses, they are the Status Port and Control Port and their addresses are 0x379 and 0x37A respectively.

eSATA Connector

eSATA was standardized in mid-2004, with specifically defined cables, connectors, and signal requirements for external SATA drives. eSATA is characterized by: 1. Full SATA speed for external disks (115MB/s have been measured with external RAID enclosures) 2. No protocol conversion from IDE/SATA to USB/Firewire, all disk features are available to the host. 3. Cable length is restricted to 2m, USB and Firewire span longer distances. 4. Minimum and maximum transmit voltage decreased to 400mV - 500mV 5. Minimum and maximum receive voltage decreased to 240mV - 500mV USB and Firewire require conversion of all communication with the external disk, so external USB/Firewire enclosures include an IDE or SATA bridge chip that translates from the ATA protocol to USB or Firewire. Drive features like S.M.A.R.T. cannot be exploited that way and the achiveable transfer speed with USB/Firewire is only about half of the entire bus data rate of about 50MB/s. This limited effective data transfer rate becomes very visible when using an external RAID array and also with fast single disks which may yield well over 70MB/s during real use. Currently, most PC motherboards do not have an eSATA connector. eSATA may be enabled through the addition of an eSATA Host Bus Adapter (HBA) or bracket connector for desktop systems or with a Cardbus or ExpressCard for notebooks. eSATA does not provide power, which means that external 2.5” disks which would otherwise be powered over the USB or Firewire cable need a separate power cable when connected over eSATA.
