Looking at replacing the PSU in my rig. Spec's below. I dont really think I need a full 1kW. I get different results with these wattage calculators on the 'net. If anyone has a better link than what usually comes up with google, please let me know and ill use that.

Need some help recommending PSU wattage for my system

Forget links, we know, LOL!
A quality 750W PSU would be PLENTY even with overclocking both GPUs and the CPU. A 650W would be fine really.
2x 670s = 340W MAX load stock speeds. about 375W (and you wont hit 375W and MAY hit 340W when overclocked to the hilt).
CPU = 77W. Overclocked, where you are or a bit further, perhaps 100-110W.
board/ram/water = 50W
So we have 375+110+50 = 535W
It won't even hit that value unless you are stress testing both CPU and GPU's while overclocked. You will likely barely break 400W at most when gaming.

Its still overkill. How about a AX760? Or Seasonic 760W? http://www.newegg.com/Product/Product.aspx?Item=N82E16817151120
(and note my edit above).

Yeah, it still would be, but it'd be nice to have for future use. Seasonic is nice, but Im slowly turning into a corsair wh0re. I'd to check out their 'i' series digital PSU's. I see they have one in 760, but the price difference between that and the 860 is $20..for another 100W.

Which Rosewill 1KW do you have? Reason is that some are just as good as the high end Corsair models, while some are meh.

That would be one of the meh ones. Not a terrible PSU but not great either. Upgrade would not be a bad idea IMO.

In the OP's case, this is true.
But some PSUs come with multiple 8-pins PCIe connectors fixed when people don't need that for their GPU.
The other thing I already like, I can pull my PSU out to dust it along with my case very easily. Just unplug everything and you can pop it out/back in really easily.

If you really want full modular (IMO semi modular done right is just as good), you could look at the OCZ ZT 750.
I can vouch for it. Currently running one right now and it has held up with 2x7970s and a 3770k overclocked. Though I'm upgrading to a PSU that has more capacity to handle my plans.
