I know that it supports Crossfire OCing for my X1950 Pros, and it should for the R6** boards too. This tool was in beta only last January, as it was designed for the R6** chip. I'm guessing they used this to test and bench the GPU, trying different clocks for memory and GPU. I would be pretty shocked if it didn't. All you have to do is select the device from the list.
I'll let you know if it saves the clocks on reboot, but I doubt it. I know that ATI Tray Tools may save the clocks if you apply them with this tool. I have done this before with another app (Winclock, ATI's older in house tool)
As for the PSU, you may be able to get a mild OC with the adapters, but maybe not as much as the dedicated 8 pin PSUs. You defintely have enought juice to run them in Crossfire, so don't let the uber PSU trend fool you. It's retarded how powerful some of the PSU are coming out now. It's really just unneeded.
