i'm debating adding another 8800gt into my 08 mac pro but i want to make sure i'm not over loading the power supply what i currently have in the machine SATA DVD 16x burner 8800GT 4 drives, all 7200 RPM. OS is a seagate Hybrid 2.5 that i acquired for free. 16 gigs of ram, all slots are populated 2 x 2.8 SLANT cpu's i am running on a 9800GT that i flashed to a 8800gt and my OEM 8800gt is sitting here. both cards are functioning but i have read in places that you might need to run a seperate power supply on a relay in order to power bigger cards with the 6 and 8 pin power adapters as the logic boards cant handle the load. would i be ok ordering a pcie to mini adapter and running them? i plan on running quad monitors.
