Just ordered a 670, will my PSU be enough for SLI?

So I just pulled the trigger on a Gigabyte GTX 670 (went with the free shipping so it might be a few weeks :( ).

Anyway, I currently have a PC Power and Cooling Silencer 750w PSU. Will this be enough to SLI a pair of GTX 670's?

Here is my current system.
Antec 1200
ASUS p8p67 deluxe
i5 2500k @ 4.0 (with Corsair H100)
2x4GB Gskill RAM
2x9800 GT SLI (soon to be a GTX 670)
2x 7200RPM HDD
PCI-E x1 Wireless Network card
Creative X-fi Xtreme Gamer

I want to have the ability to SLI a pair of 670's in the future as well as have some overclock headroom for both the GPU's and the CPU.

Yea 750 watts will be sufficent. Although i don't prefer PC power and cooling as a power supply brand. It is a Bronze rated PSU... SO yea your PC technically can handle it. (2 way of course)

What's with PCP&C silencer? And what's with the bronze certificate?
It's one of the best PSU brands and the certificate is for efficiency, the main reason I didn't get that unit is that it wasn't Modular.

@OP
Yes it will be very sufficient and you can overclock anything in your PC with more headroom.
Quote:
Measured power consumption

System in IDLE = 140 W
System Wattage with GPU in FULL Stress = 279 W
Difference (GPU load) = 139 W
Add average IDLE wattage ~10 W
Subjective obtained GPU power consumption = ~ 149 Watts

The GPU draws 150W when fully loaded, there will be no problem when you SLI.

Yeah the non-modular design is pretty annoying, but I was a newb back when I bought it and didn't know the difference :p 

Thanks both of you for the info, really good to know I don't have to drop $$ for a new PSU should I decide to go SLI (which will be very likely with the first price drops).
