Running a gtx 260 and gtx 460 simultaneously

I am wondering if it is possible to run both a gtx 260 and gtx 460 at the same time. I currently have....


and am planning on running it with...

MSI P55-GD65 USB3 LGA 1156 Intel P55 USB 3.0 ATX Intel Motherboard (

Intel Core i3-550 Clarkdale 3.2GHz 4MB L3 Cache LGA 1156 73W Dual-Core Desktop Processor BX80616I3550 (

G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL9D-4GBRL (

I am currently running two 19'' monitors on the gtx 260, have a spare 19'', and am getting a 32'' tv.

Will i be able to run the gtx 460 separately and attach the spare monitor and new tv, and run them all as 4 displays? Will my current psu be able to support this if it is even possible?

Thanks for the help.

  1. Yes you can run them simultaneously, but not on SLI mode...
    You must have the exact same cards for SLi.
    For what purpose? gaming? or just watching videos and surfing or something?
  2. If you run both the GeForce GTX 260 and GeForce GTX 460 at the same time the maximum current draw on the +12 Volt rail for just the graphics cards under full load will be 28.5 Amps.

    Since the Corsair CMPSU-550VX power supply is able to provide 41 Amps on its single +12 Volt rail it should work.

    The video cards will not work in SLI mode. They will be treated as two separate video cards and you should be able to see each display attached to each video cards' ports.
  3. Thanks for the help both of you! I wasn't sure if it was possible, but also i wanted to make sure my psu could handle it.

    Wa1, i wanted to be able to hook up the tv for movies and or videos on a larger display, the extra monitor would just be there for fun since it is just sitting around the house. I would never complain about having to many displays anyway =).
  4. Just to clarify, the psu would be supporting the other parts of my computer as well, should i still be fine as far as power goes? Having another gpu won't be using to much energy ontop of my other parts like the motherboard and cpu will it?

    Sorry I'm just trying to make sure it will work.
  5. Yes, you can do that, don't worry about that.
    And yes, your PSU is enough to handle GTX460 and GTX260 together with all components like CPu, mobo, ram, hard drive, etc...
