    PSU at the bottom of the case

    Are there and disadvantaged to this?

    Such as cabling and more importantly any cooling issues with mounting it at the bottom?

    also will psu cables stretch that long?

    as many cases these days seem to come with the psu fitting on the bottom.

    Re: PSU at the bottom of the case

    When the concept became mainstream, the 'P4' +12v connectors were often too short on PSUs, however these days the cables are long enough. Cooling wise, as long as the case has a top exhaust fan, it shouldn't effect CPU cooling negatively and it should reduce deadzone space.

    Re: PSU at the bottom of the case

    It may be slightly easier for dust to get into the psu due to gravitys assistance but I doubt it makes much difference. I think there have been stories of people loosing small parts in their psu's when they are at the bottom.

    Re: PSU at the bottom of the case

    I find that the case runs cooler with the PSU at the bottom.

    And the PSU isn't suffering from taking in warm air.

    Not if you have the other cooling correct.
    TBH, if the PSU is at the top, it will be taking in more hot air than if at the bottom anyway.

    yep, which is why my hx520 was always on full speed in my old case (top mounted). It's not really taking hot air at the bottom is it? If the cold air from the front fans is being blown in (Antec 900) then it's okay.

    Re: PSU at the bottom of the case

    i got the cosmos and it lets u mount the psu either way round, so mines sat with the 120mm on the bottom sucking cold air straight in from the vent and spitting it out the PSU, so it does not increase case temps at all !
