TP-750 + Gigabyte GTX670 Windforce OC, how to wire up?

[Simo606]

In the following link below you will see a table containing: Direct Cabling Connectors, for reference.
It lists two non modular pci-e connectors, both on different rails, they are the connectors of interest.

Basically, there's two rails I can use at 25 amps each (rail 3 and 4).

Rail 3 non modular = 1 pci-e 6+2 connector.
Rail 4 non modular = 1 pci-e 6+2 connector.

Rail 3 modular = 1 pci-e 6 connector.
Rail 4 modular = 1 pci-e 6 connector.

From what I understand the Gigabyte GTX670 Windforce OC requires both 8 and 6 pin pci-e power connectors. Having said that, I NEED to use one of the non modular 6+2 connectors, the question is should I use the other non modular connector, which is on a different +12v rail.

Question 1.
Is 25amps (300watts) enough to power a single Gigabyte GTX670 Windforce OC at full load.

Question 2.
Is it ok to mix the two separate rails that are non modular? For example, connect both rail 3 and 4 to the graphics card?

Thanks

1) Yes
2) Yes
I would use both none modular cables!
