On motherboards, the more common connector used for this purpose is the ATX 4-pin Power Connector, used either by itself or with a second 4-pin connector, creating an 8-pin connector. The terms “PCI Express cables” or “PEG cables” (for PCI Express Graphics) are sometimes used to describe a 6-pin 12V power connector. Tim Fisher ATX 6-pin 12V Power Connector Pinout (ATX v2.2)īelow is the pinout for the standard ATX 6-pin (3×2) 12V power connector as of Version 2.2 of the ATX Specification (PDF). You can see other ATX power supply connector pinouts in our ATX Power Supply Pinout Tables list.Ģ:23 How to Test the Power Supply in a Computer Using an ATX 6-pin 12V Power Connector Pinout Reference for ATX 6-pin 12V Power Connectors If you’re using this pinout table to test power supply voltages, be aware that the voltages must be within ATX specified tolerances. The 6-pin 12V power connector is used to power PCI Express expansion cards that require more power than their expansion slots can provide, which is 75 watts. Some video cards, for example, draw more than 75 watts, in which case connecting a 6-pin 12V power cable can provide more power to the card. Video cards sometimes come with an 8-pin connector if they can utilize more power than what a 6-pin cable can provide. If this is the case, but you only have a 6-pin 12V power connector, a 6-pin one will fit but won’t provide any more than what the 6-pin provides. Unfortunately, even though a smaller cable fits, some cards simply won’t work properly without the full power provided by an 8-pin connector. Added optional high current aux output socket (J5).Be sure to check your video card’s documentation to see if this 6-instead-of-8-pin configuration will work for you. Voltage clamp added to primary RPM inputĪdded Proto area. Flex fuel input added to proto areaĬonsiderable number of routing improvements. Voltage clamp added to secondary RPM input. Compared to previous design, TO220 cases now lay flat on the board, power circuit is improved, molex connector has been removed, ULN2003 is added for low current outputs and proto area is removed due to space constraints.įilter capacitors added to both primary and secondary RPM inputs. Modified for easier automated assembly, including some SMD components and mounting the pressure sensor flat side up. It is electrically and physically compatible with all other v0.4 versions. A new ground up, all SMD, board design that includes additional onboard drivers and protection circuits.
