    Default PCIe Power Output Question...

    I was going to buy an AX1200i but it seems overkill and since the HX1200i provides the same power I decided to go with this one instead however I have a question and I need some one that knows this to give me a sound answer. Here goes...

    AX1200i has 4x single cable (6+2) and 4x daisy chained (8pin+6pin) connectors on 2x cables. So AX1200i has a total of 8x PCIe connectors on 6 cables. However the HX1200i has 4x PCIe cables and all of them are daisy chained (8pin+6pin). So HX1200i has 8x PCIe connectors on 4 cables...

    Coming to my question... Can a single daisy chained (2x 6+2 pin connectors) PCIe cable, on the HX1200i provide 275-300w (23-25amps) of power to a single R9 290? I have 3 of these cards in crossfire on a 1000w PSU on SEPERATE PCIe cables not daisy chained and they work fine. However I want a higher wattage PSU just in case I add more components later etc... Can one single daisy chained PCIe cable handle this kind of power for one card?

    Please I need an answer!!!!

    Thanks for the answers if any...

    Yes it can, a single GPU graphics card without (extreme) overclocking should always be fine. With dual graphics card like the R9 295X2 and Titan Z, you need to use two PEG cables.

    Some people are saying that Jonnyguru have said that a single R9 290 would need two seperate cables. Hence that is what contradicted me...

    Probably just when doing really high overclocks with volt mod

    Does the 8pin + 6pin cable (single cable) provide 150w+75w for those pins for a total 225w?

    An 8 pins PEG connector is rated for 150W and a 6 pins is rated for 75W, but they both can deliver a lot more.

    Yes but do they provide 225w on the SAME cable (not seperate ones)? All I want is a stable, high quality PSU. I currently have an OCZ ZX-1000 which is cutting very close to its limit... hence I need a better PSU...
