I'm very eager to buy this PSU, but I have one issue that's still bothering me.
Can this PSU adequately power Radeon HD 2900 XT graphics card when connected with one 6-pin PCI-E and one 8-pin PCI-E connector? I'm pretty sure that it will run with two 6-pin PCI-E connectors, but unsure how it performs with one 6-pin and one 8-pin. I'm asking this since other manufacturers "strongly recommended to choose the connectors from exactly the same +12V rail" (can anyone tell me way???), and because I don't have info (at least I couldn't find it) on M850's PCI-E connectors rail distribution I'm not sure how the whole thing would work.
I'm also wondering way this PSU isn't ATI Crossfire certified, and of course, is it even then possible to run two of Readeon HD 2900XT in crossfire connected in same manner (6-pin + 8-pin) as mentioned previously.
The rest of configuration is pretty much standard (X38 mobo, C2D E6850, 4GB DDR2 PC-8500, one HDD 500MB, FDD, DVDRW, 4 case fans).
Does anyone has experince with this? Any information about it?
Any help would be appreciated.
Thanks in advance.
