Nah, didn't think so. Considering the PCI-SIG rates the PCI-E slot for a nominal 75W power delivery, where the hell else do you think the board draws its power from? You think a SC cluster or data centre has ATX PSU's ?? Maybe you should watch this and point out where the PSU's are, or maybe tell these guys they're doing it wrong. Which is already what I've said...and much earlier than you did, so why the bleating? Oh, I know why,...you just need to troll. Nothing at all, except possibly change the cooling and power cabling - and no I don't mean just the individual 6 and 8 pin PCI-E connectors. I mean the main power conduits from the cabinets to the power source. Then of course if a cabinet is being refitted for S10000 then you would have to re-cable all 42 racks in a cabinet for 2 x 8-pin instead of the nominal 6-pin + 8-pin at four cables per rack multiplied by the number of boards per rack, as well as the main power conduits...then of course you'd have to upgrade the cooling system -which for most big iron is water cooling and refrigeration.
