650W PSU enough for 2x 760 4GB?

post #1 of 7
Thread Starter 
I just bought 2 EVGA 760 4GB cards, have 3x 8GB 1600Mhz ram, and i7-4770k, 2 1TB HDD and 1 SSD, with case fans I should still be good on my power consumption under load correct? I don't plan on OC'ing the cards just yet, so as it stands I should be fine right? Just trying to plan ahead in case I need to run out and buy a new psu

Yep, it's enough

I have the same psu, used in a 3970x and GTX 690 system a while back:



The GTX 690 was locked at around 1.2v.

Notice the voltage on the 3970x? That chip has since died and now I have a newer 3970x that hasn't seen over 1.6v ever.

The AX650 is in a modest rig, retired after heavy use!

Edit: These are Superclocked 760's, not sure if that makes a big difference or not.


Ok, now since my psu only has 2 6+2 connectors, I need to use 2 molex > 6pin pci connectors. Is this a terrible thing to do? unfortunately I don't have another option as I am pretty sure I can't split the 6+2 into 2 6's correct?

That is what usually people does when they ran out of pcie connectors

And the power usage would be slighly higher.but not ocer 500w under load

Should have 4 pci-E cable connections available for 2 cards.

You could use the molex to pci-E adapters. You will not have an issue since your voltage on the cards are at 1.21v or lower.
