    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
    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.

    Sorry to hijack the thread but we may as well hit two birds with one stone...

    I have a 2009 2.26ghz 8core

    4 drives all 7200 (as you)
    32gb ram, 8x4Gb
    Gtx770 (MacVidCards flashed)

    I should be ok too?
