Hey, will I be able to have 2 GTX 770's on a 650W PSU.

I'm using an i5-4670k, a GD65 gaming motherboard and 24 GB of G.Skill Sniper Series @1866 MHz.

Thanks!

Its very risky to do that, especially if your 650w psu is not good quality. I suggest at least 850W to use 2x 770 in sli.

I already have a SeaSonic modular 620W PSU. I guess I'll just have to get a new one.

Do you need any suggestions or do you got this yourself?

  • Yes, that is a good choice. Most sources recommend 850 for two 770's in
    SLI, which is the same as 2 780's. The 770's do in fact use a little less power

    So, the XFX 750 will run your system.
