    Default Difference between EPS12V and ATX12V 8 pin connectors?

    Was trying to fix up my EVGA 680i together with a Thermaltake Toughpower 1200W W0133.

    This PSU comes with both EPS12V and an unknown 8 pin connector, according to JonnyGuru.



    From the PSU manual, it states:



    The board comes with a connector that requires ATX 12V 8pin.



    As you can see, the real EPS12V connector doesn't exactly correspond in shape to the 4+4 connector in the manual.

    On the otherhand, the unknown connectors corresponds exactly to the one on the motherboard.

    The dilemma: I have tried and both connectors will fit into the motherboard.

    Checking the PSU and motherboard manuals, the ATX 12V connector must have 4 grounded pins. So I am right to say EPS12V == ATX 12V connector (4+4), since the unknown connector has 4 COM pins?

    I certainly don't want anything explosive to happen. What's the name for the unknown connector? Is it even part of the ATX12V 2.2 specification? Which 8-pin plug should I connect to my motherboard?

    Either the one that is different is the 8 pin PCI-Express.

    Yep. You're over thinking this.

    ATX12V and EPS12V is only one pin off. But that pin is a D instead of a square, so it'll fit (D's can fit in square holes.)

    If you look at the wiring, you'll see they're the same (three +12V and three ground.)

    If there was a "risk" of frying anything, they would have made the connections not interchangable.

    OK, let me see if I get what you're saying:

    The left connector is an EPS12V connector, and the right one is the ATX 12V. Both will be compatible with this motherboard.

    If thats the case, it means "COM" actually means "GND"?

    Thanks.

    Why is ATX12V and EPS12V just one pin off?just confused?

    So that you can use either half of the 8 pins in a single 4pin ATX12V socket.
