I want to buy another MSI GTX 760 4GB OC to have two in an SLI configuration. My current setup is this:

Cpu: Intel i7 6700K 
Mobo: MSI Z170 M9 ACK
Ssd: 2x Samsung 850evo 500GB
Psu: Corsair RM 650
RAM: Kingston Hyperx DDR4 2666MHZ 15cl
Gpu: MSI GTX 760 4GB OC
Case: Corsair 780T Black

Will my current system support a second graphics card? Will I have to upgrade anything before it will work?


Motherboard supports SLI, so no problem there.

While the RM-650 isn't ideal for SLI in general, it's a fairly decent unit and has the required connectors (4x 6+2-pin PCIe). It should be able to provide the power for this specific situation. The MSI GTX970 will requires about 150-200W under load (tests at bit-tech and Guru3D), so should be okay.

Only potential problem is if you overclock everything and burn both the CPU and GPUs at the same time -- that's the only way I'd see it getting close to the limits of the RM-650.

Other possible issue is whether the case has enough room/cooling capacity for the two cards, but case isn't mentioned so can't really tell. Edit: Case is large and roomy, should be no problem there either. Just check the GPU temps are okay under load to make sure they're getting enough airflow as there's no possibility of a side-of-case fan.

  • While your answer is correct and valuable to the questioner, this kind of reccomendations are off-topic on this site. – KarmaEDV Oct 2 '15 at 8:38

    @KarmaEDV This question is off-topic on Hardware Recs, but on-topic here. OP isn't asking what graphics card to buy, he is asking if it would work in his current setup. I do agree that it does need work however. – Cfinley Oct 2 '15 at 16:13

    @Cfinley: I just find it amusing that some users are using downvotes to punish answers they <i>say themselves are valuable</i> because they believe the question is off-topic, rather than just voting to close the question... – Ash Oct 2 '15 at 23:51
