8 pin motherboard auxiliary connector definition Pc#
This will likely give enough power, but beware over-clocking.ĪTX Power Supply Pinout and Connectors COMPUTER POWER SUPPLY: PINOUT, CABLES, CONNECTORS Computer power supply units (PSU) deliver the power to the PC hardware via a number of cables with connectors. If compatible then it will go in on “one side” of the 8-pin connector. If your power supply only has a 4-pin connector, it’s still quite likely that you can use it in an 8 pin port. It won’t damage anything, but the motherboard will detect the difference and either not start up at all, or run in a VERY restricted mode. It is entirely possible to just plug the 4-pin connector in the 8-pin slot. The 8-pin connector is literally designed as two of the 4-pin connectors put together. If you want to connect our PSU into a 4-pin EPS motherboard port, simply pull the two halves of the connector apart and connect one half into the motherboard port.Ĭan a 4 pin ATX connector work on the 8 pin ATX motherboard? How do you connect 4 pin power supply to 8 pin motherboard? Our power supply units (PSUs) use an 8-pin EPS12v CPU cable that can be split into two 4-pin connectors. 8-pin connectors have 4.2mm pitch and can deliver up to 150 watts, twice the amount that a 6-pin connector is capable of.Ĭan I use a 8 pin in a 4 pin motherboard? What is an 8-pin GPU Cable? 8-pin power connectors are found in high-end graphics cards. The four pins that you are leaving open are just redundant lines for higher current capability (see this guide to ATX connectors and pinouts). Technically, a 20-pin ATX connector can be plugged straight into a 24-pin motherboard socket, leaving male pins 11, 12, 23, and 24 unconnected. It won’t damage anything, but the motherboard will detect the difference and either not start up at all, or run in a VERY restricted mode.Ĭan you use a 20-pin ATX on 24-pin motherboard? The ATX 4-pin power supply connector is a standard motherboard power connector used to provide +12 VDC to the processor voltage regulator.Ĭan a 4-pin ATX connector work on the 8 pin ATX motherboard? What is the 4 pin ATX power connector for on a motherboard? This is done via the 20-pins or 24-pins connector.
The primary task of the Power Supply Unit (PSU) is to provide your motherboard with power.
Usually motherboards should have at least 1-2 4 pin connectors for the CPU, as well as a couple of 3 or 4 pin connectors for case fans. How many pin connectors does a motherboard have? How many pins does an ATX power connector have?Īn ATX power supply provides a number of peripheral power connectors and (in modern systems) two connectors for the motherboard: an 8-pin (or 4+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.
