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.

  1. 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.

    Yes it will be very sufficient and you can overclock anything in your PC with more headroom.

    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).
