    Default 8 to Dual 8 Pin EPS for high power current generation Boards

    Does this exactly works

    As i can see only very high capcity psu say 850+ watts on rmx , RMI and hxi

    have these 2 pin cpu connector's.

    it seems overclocking gone beyond 5ghz and for that to achieve new generation board demand either 8+4 CPU or 8+8 cpu pin for extreme stable overclocking.

    I just wondering in all these years cpu power also increased and they cant do with current 8 pin which now got doubled.

    Does the above pin works

    if so how to calculate the power requirement including amp's .

    BOARDS CURRENT GEN

    Nobody knows what you're asking.

    It's true that high end boards have more than one CPU power connector. And it's also true that you don't tend to find more than one CPU power connector on most power supplies unless they're high wattage.

    The motherboards work just fine with only one power input.

    The purpose of the multiple CPU power connectors is more about less resistance, causing less voltage drop, than the ability to deliver more power.

    A single 8-pin EPS12V CPU power connector can actually deliver quite a bit of power.

    Got it . But does the link to y splitter can work with those boards.

    i am afraid thought i might not end up with these boards. But soon say 1 year down the line boards are going to come with 12pin or 16pin connector's as the demand for 5ghz cpu frq is increasing.

    If all these low wattage cant power it to enjoy that speed. Does this y splitter can deliver.

    If so how much is the rated power an 8pin cpu connector can deliver.

    if one is using y splitter what kind of load the rail will face .

    As basically the cpu may not take more than 65-90watts. If twice consumptio assuming possible going to hit 180watts means the psu should have enough headroom to support y connector load

    But wattage alone not the only criteria as the power consumption increase the ampere also increases. So it have some limitation. especially with single EPS 8 pin connector load

    No. The splitter is a horrible idea. It does nothing. It's only needed if the motherboard REQUIRES both EPS12V ports to be populated. I've seen VERY FEW motherboards that required both to be populated for the PC to even POST.

    oh ok. I little worried if the future demands such a EPS 2 pins.

    hoping it will stay with 8 pin for few more years to comes

    CPUs are getting more efficient. Not less.

    I've had a similar question I've been trying to get eVGA and ASUS to answer but neither want to officially respond. eVGA PSU's come with some of these 'y splitter' CPU eps power cords in the box but I can't get a clear response from anyone if it's fine to use them on higher end boards with 2 eps power ports on the motherboard when the PSU only has one port.

    I guess 2 (or more)-socket WS/server boards with independent VRMs?

    And some of them may work with 2x4pin populated...
    with an adaptor you'll burn the connector due to overcurrent for that connector. So no, do NOT use such Adaptors ever.


    Even when current is not an issue, the Board manufacturer wants you to use separeate cable from the PSU for various reasons.
    ANd not want you to use any kind of adaptors!! Those are totally useless in these cases.
