Horror stories about radeon HD 2900 XT power unit requirements was removed, only one real inconvenience remain : the impossibility to overclock using drivers and supports regime crossfire with two six-pin power connector . We note again that the absence of octal power connector is not an overclock obstacle .
The new octal pin power connector will be used by video cards that support PCI express 2.0 interface . Through the motherboard slot PCI express x16 of , that supports the standard PCI express 2.0, it is possible to give video card up to 150 W power. The two additional power connector also give 150 W . As result, motherboard with PCI express 2.0 support and the corresponding power unit allow to use video card capable of consuming up to 300 W.
Let us recall that motherboard and video card with support of different versions PCI express possess comprehensive compatibility, simply PCI express 2.0 proposes large power and higher data rate exchange . Since AMD already demonstrated systems on the base of chipset RD790, supporting PCI express 2.0, it would be interesting to see how this motherboard will work with video card radeon HD 2900 XT.
Thus, video card radeon HD 2900 XT works with one six-pin connector , the remained power is ensured by the PCI express x16 slot. During July will appear the chipset Intel x38, which will also support PCI express 2.0.
