1. bought a K series and did not over clock it??
2. The 4770K is 84 watts TDP
3. I assume you have a HD and RAM so add another 25 watts
4. Your losing 10+% through the PSU
5.Fans? cooling?
Figure bare minimum pulling 150+ watts without the GPU's. If your getting 680's to run at 60 watts each Nvidia and Intel will break down your door to figure out your secret. At that wattage you can just pull power from the PCI-E slot and passively cool. oops, There is another 2 fans I overlooked..
1 : this is not me with the 4770
2 : TDP doesn't always get hit, at load with something super intense sure, but even BF4 seems to top out at lower usage with 8T processors.
3 : Fans, HDDs, and RAM typically use very little power
4 : I think many regret buying the 4770K vs. 4770 due to lost features and low OC ceiling, I see more 'stock clock' K-series Haswells than Ivys or Sandys.
And finally :

When we place load on the CPU and we see the power draw rise,
the system now consumes roughly 135 Watts. This is with merely an SSD, memory
and a GeForce GTX 580 installed. Your average PC will draw a little more power if you add optical drives, HDDs, soundcards etc.
GTX 580 is more power hungry than 680.
Yes, this was probably not a GPU-loaded scenario.
That WAS using a DH-14 (yes, fans take very low power)
Look, I'm not saying for sure one way or the other, I'm just playing devil's advocate here. I have seen MANY reports of power usage like the one described. Can you bust through that level of power with Furmark, IBT, the right game? Sure you can. The fact remains that many games don't even make that great of a use of your system though, and so power usage doesn't necessarily go bananas. Synthetics are invariably the most you can get a system to consume. I run BF3 at 1920x1200 with all ultra, and my GPU fan never ramps up to an audible level, and I'm two feet away from my case. Run Furmark for a few minutes though, and it sounds like a helicopter.
EDIT : Power consumption notes :

(that setup uses a 3960X, which is VASTLY more power hungry than a 4770 stock)
