What is the P8 cable for?

Alternatively referred to as the AT style connector, P8 connector, and P9 connector, the P8 and P9 are IBM power connectors. They connect the power supply to the motherboard on AT, Baby AT and LPX motherboards. Although these connections were keyed, these were replaced by the ATX style connector.

What is a P2 connector?

The P2 is a 6-pin connection that uses 4-pins (the other 2 are blank). I’m trying to find a pin diagram for this P2 connection so I can make an adapter to plug into the standard ATX 24-pin from the psu.

What is the difference between AT and ATX power supply?

AT-style computer cases had a power button that is directly connected to the system computer power supply. An ATX power supply is typically controlled by an electronic switch. Instead of a hard switch at the main power input, the power button on an ATX system is a sensor input monitored by the computer.

What is a p4 connector?

1. The P4 connector is a 12V power supply cable used with motherboards that have an Intel Pentium 4 or later processor. Today, the connector is a standard power connector and is used with both Intel and AMD motherboards. All of these wires attach to a four pin connection on the motherboard.

What is a P5 cable?

Type P5. Used in low voltage energy distribution where fire resistant to IEC 60331 is vital. This cable provides circuit integrity to continue essential service in the event of fire. Widely used on ship, oil rigs, platform and refineries.

What kind of ATX to P9 power supply cable?

. This cable converts a 20-Pin ATX connector to 6-Pin P8 P9 AT connectors and two wires for the on/off switch. Would you like to tell us about a lower price?

What’s the difference between the P8 and P9 connectors?

With the introduction of ATX, motherboards and power supplies were replaced by the ATX style connector. One of the most difficult and troublesome parts of this connector was the fact that both the P8 and P9 connector looked identical. Although these connections were keyed, these were replaced by the ATX style connector.

How does the ATX power supply adapter work?

It reroutes all the power rails from an ATX PSU to their AT equivalent pins/connectors, as well as breaks out the “Power On” power supply signal that is normally provided by the motherboard. This allows you to connect it to an old fashioned hard switch on an AT case, OR, to connect up some sort of other hard switch.
