    You really shouldn't try to run 300+ watts through a single 8 pin cable.  You REALLY want both. 

    -CP-9020178-NA-Gallery-RM650x-PSU-06.png

    The PSU has two connectors for cables.  Find your second cable.

     

    Pushing too much wattage through too little copper can cause overheating, melting, shorting, and then fire.

    It's a bad plan.  The 3090 uses 150+ watts more than the 1080?  Or something like that.  It's NOT a small change in power draw.

    So you are telling me that every single PSU manufacturer has been breaking electrical safety laws for at least the past 15 odd years?

    Just leave the card in it's default state. Cause OCing with only 650w even if it's Corsair is kinda dumb in the first place.

  2. Running AMD and NVidia drivers at the same time isn't really an issue anymore. Windows' stupid DM accounts for the majority of issues.

     

    It's possible to specify which processor will do physX work. iirc it can even be specified on a per app basis.

     

    Some games will have problems with physX and rendering being done on different cards. Only solution is to run the game and physX on the same card.

  3. 2 (3, or 4) GPU's can work in a single PC and each can output to multiple monitors.

     

    Using your diagram.

    GPU 1 can't control or contribute anything on monitor 3/4.

    A game (or any application) running and displayed on monitor 1 will only use the resources of GPU 1.

    So using your example of GTAV. One instance can run on monitor 1/2 and a second can run on monitor 3/4 without affecting the first.

    The CPU may be a bottleneck here as its workload is doubled.

     

    Applications can be freely moved between all monitors at any time. Note that GPU/VRAM heavy apps might have issues.

     

    All 4 monitors will be discrete, meaning full screen apps will only fill a single screen. Both AMD and NVidia have methods of combining multiple monitors from a single GPU into a single large virtual display. Allowing a full screen app to fill multiple monitors without any special support.

    Crossfire/SLI can be used in conjunction to combine the power of multiple GPUs. Performance does not scale linearly using Crossfire/SLI. 2 GPUs will result in a -20% to 70% perf increase.

    Note that Crossfire/SLI can only be used in programs that support it.
