Default TX650M need 2 extra PCI-E 2X3 connectors

I want to drop a 2nd graphics card into a computer with a TX650M PSU in it. I've already got the 2 PCI-E power connectors that came with the PSU in the first graphics card.

There are 4 modular plugs on this PSU, two are blue and are 2X4. Those are the two that are currently in use. There are 2 more plugs available that are black in color, and are 2X3.

Are these black plugs capable of being used for 2 more PCI-E cables? I don't even know if they can be used for this, and it's unclear if any of the extra cables on corsair.com are 2X3 or 2X4.

The 2x3 plugs you are referring to are for peripheral power. There are molex to PCI-E connections, but I'd highly recommend against using them. What GPUs are you using? 650w may be fine for some cards, but may not be for others.

Arrow I would never use Molex to PCIe cables

I feel using Molex to PCIe cables is almost asking for trouble!

A GeForce 550 and a 660 is my goal. A 650w should cover both cards.

I do not want to use a molex to PCI-E adapter. That's why i'm looking to see if I can use additional modular PCI-E cables with the PSU.
