![]() The 6+2 PCI Express power cable is made up of two pieces: a 6 pin piece, and a 2 pin piece. Many power supplies come with a 6+2 PCI Express power cable which is compatible with both kinds of video cards. Since the tertiary connector is optional, most consumer motherboards do not include it.ĮDIT: As i7baby mentioned, dual-socket motherboards have two 8 pin EPS connectors. Some video cards have 6 Pin PCI Express power connectors and others have 8 Pin PCI Express power connectors. So if your graphics card power consumption is more than 150W then it will definitely come with an 8-pin connector or two 6-pin connectors. If you're confused by what I mean by a tertiary connector, see the Rampage IV Extreme motherboard, it has a 24 pin main connector, 8 pin EPS auxiliary connector, and a 4 pin tertiary connector. 8-Pin connector The 8-pin power connector can deliver a maximum of 150W to your graphics card. ![]() High end power supplies often have a single 8 pin EPS connector and a 4 pin connector which can serve as either an ATX auxiliary connector or an EPS tertiary connector. temperature reaches the pre-defined threshold, the CPU thermal trip. 8-pin EPS connectors can be divided into two 4-pin EPS, and a 24-pin ATX can be split into one 4-pin ATX and a 20-pin ATX power connector. The flex cable (flex circuit) motherboard connector pins and their corresponding. Modern PSUs often provide EPS and ATX power connectors that can be split. The new 24 pin connector added one line apiece for ground, 3.3, 5, and 12 volts. The older 20 pin main power cable only has one 12 volt line. The 24 pin main power connector was added in ATX12V 2.0 to provide extra power needed by PCI Express slots. On mid range power supplies (those under 1,000 watts) it's common to see a 4+4 pin connector which can satisfy the requirements of both the ATX and base EPS specifications. Diagram of a 10/100 BaseT connector, showing its 8 pins. Other form factors include LFX12V (low profile), SFX12V (small form factor), EPS12V (used with server motherboards and has an extra 8-pin connector). 3 Answers Sorted by: 8 The 24 pin EATX power connector. Strictly speaking, the ATX standard specifies a 4 pin auxiliary power connector and the EPS standard specifies an 8 pin auxiliary power connector and an additional optional 4 pin tertiary power connector. ![]() Now I noticed the 8 pin EPS connector that provide extra power to the board, only has 6 wires connected to it. So both 4+4 Pin ATX12V / EPS12V and EPS 12V 8-pin ATX12V / EPS12V will work, what is the difference? 12672 03-30-2021 05:21 AM Aurora R10, 1000W PSU, 8 pin EPS connector So I have been looking at my motherboard, to determine if in the future I can move over the power supply to a different case and motherboard. ![]()
