Power for 3/4 x VGA cards?

[Spectralis]

I'm planning to add 2 more NVidia GTX 760 cards but I'm trying to work out how to connect up all the power cables correctly. The PC I've built is running perfectly so far with one VGA card so I want to make sure I don't mess things up when I add more cards.

My PSU is the EVGA SuperNOVA 1300 G2. The PSU manual is sparse on information to say the least. I think I've worked out correctly how to connect up the cards to the VGA connectors on the PSU but the Maximus VI Extreme manual states that multiple cards need extra power from the six pin EZ_PLUG_1 mobo connector near the top card. The PSU didn't come with a 6 pin connector (apart from the VGA cables that I need to connect to the cards) so do I need to connect an extra power cable to the EZ PLUG and if so what cable do I need and where can I get it?

I've sent a support request to EVGA but maybe someone here can advise?

The key thing is having enough PCIe connectors and that psu should have.

Use two of the dual PCIe cable for the first two cards and then two cable per each of the third and fourth cards.

Thanks for your help. I'm going to connect the cards in this way but I'm not sure how to connect the EZ_PLUG_1.

Once I've connected all the cards the PSU will have a 'peripheral' connector and a 'cpu' connector free. I could connect a 'peripheral' cable that has a dual molex to 6 pin PCI-E adapter to the EZ_PLUG_1 connector or I could use a spare cable from another PSU that fits the EVGA 1300 'cpu' connector and has a 6 pin PCIE plug at the other end. I'm just not sure which cable will carry enough (or either too much or too little) power.

The EVGA PSU provides for 4 x VGA cards but not for extra PCIE power to the mobo it seems? When I researched what PSU to buy the EVGA 1300 specified 4xSLI so I thought it would be ok.

Yeah not all boards have the same power connectors so it is very hard for any one PSU to suite all motherboards. You can do the extra cable that does fit, or get an adaptor and use the 4 pin molex.
