Thank you for your answer.

WHY NOT???

Two 970s in SLI should be fine. They are very power-efficient.

Yes that is the perfect amount of wattage for your system. And that model of PSU is well above average quality wise. Good luck with the build!

Can a Corsair HX750i < Yes it can easily power your system

Nice choice on the power supply. 😀

I notice everyone is saying yes to this. However, Pcpartpicker says "1 additional PCI-Express 6-pin power connector is needed':

http://pcpartpicker.com/p/d9bmWZ

The specs also say it only has 3 6+2 connectors, whereas GTX970's in SLI will need 2 each (from what I understand).

Can anyone clarify this?

Partpicker is wrong.

NewEgg's description is also wrong. When you look at NewEgg's own picture gallery it shows that there are three PCI-E cables with each cable having two (6+2)-pin PCI-E connectors on them.

 

[badboyrog2]

6+2 pin PCI-E, 6+2 pin PCI-E 600+150mm
6+2 pin PCI-E, 6+2 pin PCI-E 600+150mm
6+2 pin PCI-E, 6+2 pin PCI-E 600+150mm

so plenty of pci-e...3 connectors


excellent voltage regulation on all three main rails
excellent ripple suppression on all three main rails
fully modular
Corsair Link enabled
7 year warranty

Thanks for the responses.

However, when the specs list the #6+2 PCI-e connectors, I thought it was referring to slots in the PSU itself, not the number of cables.

The HX750i has 5 slots which it labels "6+2 PCI-E and 4+4 CPU". Can the 4+4 CPU slots be used as PCI-e for the 2 SLI GPUs which will need 4?

The Corsair H750i doesn't come with four modular PCI-E cables, only three. You only need to use two of those modular PCI-E cables. Each graphics card on its own cable.

I don't think you guys are understanding my question. You keep going back to cables.

The GTX 970 requires a 6pin AND an 8 pin connector. Therefore, 2xGTX970 in SLI will require 2* 6pin and 2*8pin connectors to work for a total of 4 PCi-e connectors (http://www.msi.com/product/vga/GTX-970-GAMING-4G.html#hero-specification).

If the HX750i only has 3 6+2connectors (the slots not the cables) then I don't see how it can power GTX970's in SLI. And please, no more about cables.

each harness have two pci-e connector ...so each harness feed one gpu card ..you have 3 harness total
so that make 6 pci-e connector total ...good for 3 gpu card
there is a picture here to explain
