20 pin 12v atx power connector definition

WIth 3x +3.3V orange wires or +5V red wires. (Not to be mistaken for the Auxilairy ATX connector which looks the same)Ī similar looking P10 connector can also be found on some rare AT PSUs. P8 and P9 connector MUST be plugged in so that the black wires are side by side (together in the center) Pin2 can be found empty, although the norm required a 12V yellow wire. A beveled pin is universal and fits any socket. Pin2 can be found empty, although the norm required a 12V yellow wire.Ĩ Pin connector for PCI Express graphic cards. (Not to be mistaken for the P8 or P9 ATX connectors which look the same)Ħ Pin connector for PCI Express graphic cards. See our PSU page for older PSU with Aux ATX Connector. Replaced in 2004 by the 24pin connector, this 6pin connector is now obsolete (the extra 3.3V and 5V rails it provided are now incorporated in the 24pin connector ). Sometimes required on old boards with AMD Dual CPUs to provide more power. Most drives do not require this +3.3V wire.īy the PSU itself rather than the motherboard )Ĩ Pin EPS connector: ( Entry-level Power Supply) required on dual CPU boards. Up to 6 Peripheral (2x Triple Molex 4pin) Up to 9 SATA (3x Triple SATA Cables) 1 x 6-pin PCI-E. 1 x Main connector (20+4Pin) 1 x 4+4 Pin ATX12V / EPS12V not needed if you use 8 pin. SATA adaptors connected to a Molex do not include it. You can use the 8 pin it has 2 CPU power connections. Note that the orange +3.3V wire is not always present. In this case ask for a 24 to 20 pin adaptor orĤ Pin 3.5' Connector for Floppy Drive and other peripherals. The presence of the 4-pin +12V connector indicates that a power supply is ATX12V. The purpose of this new connector is to deliver more +12V current to the motherboard than is available from the standard ATX main power connector. Too closed to the socket and prevent the 24pin connector to be pushed all The power supply connector is a Molex 39-01-2040 or equivalent. This may not be possible if some motherboard components are There is only one way theĬonnector can be plugged in so there is no risk of error. The 4 unused pins (black, red, yellowĪnd orange wires) are simply left hanging. <<<< Note that an ATX PSU with 24 pin can be plugged into a This is a sensor which m onitors the voltage in the wire. Some wires, usually the orange wire at pin 13, may have a thinner brown wire attached to them. Some HP Pavilion Slimline Computers require a PSU with a Mini 24pin The 8 pin is for the CPU and the 20+4 is the bulk of the other motherboard items. Some Dell, WTX or AMD PSUs may have connectors with a different pinout. This may be a year later, but yes, you are correct in what those connectors are for. See our PSU page for older PSUs with -5V wire. It is now missing on all 24pin connectors. The white -5Volt wire (pin 20) became obsolete with the removal of the ISA bus on modern boards.
