What about this one?
https://www.overclockers.co.uk/showproduct.php?prodid=CA-011-XF
It's on offer, and it's got the same parts as the seasonic 1000w for a lot less than all of the above.

Although even 860w is plenty, especially for a haswell rig. An overclocked 4770k system under gaming load with a single GPU can pull around 300w, so 500w for a dual gpu setup + overhead leaves a good wattage at 650-750w. Anything above is just extra.

(the only reason i picked up that psu is that it is equal to or better than, and cheaper than all of the other lower wattage platinum psu's that come under the right wattage category. It's probably going to idle at about 5% load :p

AX860i is largely enough for two GTX670 although I see you are buying GTX680 waterblocks...

As for the SP120 fans, listen to me, don't dare to buy those. Even at 7V (~1200rpm) they are 5 times louder than the Noiseblocker Blacksilent Pro 140mm PK2 (1200-1400rpm) on the HWlabs SR-1 rad that I bought. Once upon a time I thought these fans are great (they are for performance) but they are really not silent when compared to other fans suitable for rads. Right now I am waiting to buy something else from ocUK so that I might replace the 3 SP120 that I currently have.
 
A 750W PSU will be ample for your setup!

My system in sig pulled around 330w from the mains at full load.
 
Yeah I have the EVGA signature 670 FTW cards which are apparently reference 680 boards but with 670 components on them hence the 680.

I think I will try it with the 860i, if it goes over i can always dump it on ebay and buy something larger if needed.
