One nice thing about the X3 is that it has native support of the upcoming 8 pin PCI-e standard. No adaptors needed for this baby although as of now the 8 pin cables feed off a 6 pin plug on the unit. A little birdie tells me that Ultra has a redesign in the works which will put the 8 pins on native 8 pin plugs on the PSU body and two of the 6 pin cables will adapt down from them instead of it being the inverse as it is now. Does it make much of a difference? Not really owing to the fact that as of now the extra two pins on the 8 pin plugs are grounds. There's all this hoopla over the 8 pin handling more wattage when in fact there are still three 12V power leads and five grounds rather than three +12V and three grounds. The new standard will eventually implement a 12V sense where the new grounds reside. How this equals more power capacity I really don't understand but I suppose that better minds than mine have decided it will work so that's all that matters.
