Two GPUs on my MB

I'm looking to add two GPUs to my ASUS Z87-A motherboard, and i'm wanting to run two TITIAN Xs on my ASUS Z87-A, is this possible or will i need a new motherboard?

Cheers

Hi,
I believe your psu might be a little stretched with 2 of them
1 is no problem but with 2 it would be best to have a minimum 1000w
evga 1000 P2 are pretty reasonably priced and very good.

The minimum power supply for a titan x is 600w

Hi so if i add two TITAN Xs will i not need 1200w EVGA P2 ?

Do you know if my MB will hold two TITAN Xs

Yes that is right. This is what it says on the NVIDIA page about the Titan X:

Thermal and Power Specs:
91 CMaximum GPU Tempurature (in C)
250 WGraphics Card Power (W)
600 WMinimum System Power Requirement (W)
6-pin + 8-pinSupplementary Power Connectors
And yes your motherboard will most likely hold the two GPUs the bigger question is that will they be too long for your case!

Cheers mate

That is the size I would get to sli any 980 or titan but the maximum power draw is lower than the minimum psu requirement posted on the spec's sheet I can't see what the maximum power draw is though ?

If your board has at least 2 pci-e slots it's capable of sli'ing any gpu,

The gtx750ti says it's 9" long
EVGA - Product Specs - EVGA GeForce GTX 750 Ti w/ EVGA ACX Cooling
The titan's show they are 10.5" so they are 1-1/2" longer so I'm not sure how long the gtx780's are and that is what you have now so I would measure it and confirm.

Cheers guys. I will measure available room tonight and see what gap i have left over next to my GTX780.

I looked into my MB today and only seen one yellow PCI-E slot which my GTX is in

  • Expansion Slots2 x PCIe 3.0/2.0 x16 (x16 or dual x8)
    1 x PCIe 2.0 x16 (x2 mode)
    2 x PCIe 2.0 x1
    2 x PCI
Slots look pretty normal to me
Second card would go into a 2.0 slot that's all.
