Here's my system:
 
Core i5 4570,
EVGA GTX 770 SC 2GB
Giagabyte GA-H87N-WIFI
1 TB HDD 7200 PM + 250 GB SSD
 
The box says 600W recommended (42A on +12V) but the PSU is 500W(40A on +12V). Also can I expect to do medium overclockinh on the GPU? maybe +50 Mhz on core clock?

    I have a 4670k, a MSI 770 TF, hdd and sdd, a z87i pro and all work well, and I can overclock my gpu too.

    Easily, those recommendations are waaay overblown, to account for crappy gpus. This has been asked many times all over the web, and the answer is, even a quality 450 can handle a 780 and i7, with a few drives, etc.

    A system with an overclocked i7 Extreme and a 770 at full 100% load will pull around 375 MAX:  
     
    Dropping to a locked 4570, you'll drop about 50w or so in draw, so you're looking at peak draw of around 325w.

    The PSU has a high sustained power and has been tested with multiple high performance cards such as the 780 Ti and the Titan, to add on to previous posts.

    Given that GTX770 is a 230W card (drawing under 20A each) and that the max overclocked power of even an i7 in LGA115x is around 160W (or 13A), that is the majority of the power drawn from 12v in any system, which is way less than the 40A max.
     
    That is the catch many folks don't understand about OEMs: nVidia's PSU requirements take into account even the low quality models, because they can't control which ones we get.  But an OEM can control what PSU to get, and so they will pick a PSU they know works after testing and certifying it for their uses, and it is usually lower than nVidia's requirements-- but then OEMs also don't anticipate user upgrades so their PSU choices don't reflect that capability.  
     
    While EVGA is effectively an OEM given they choose a rackmount 1U server PSU for this task; they have done their homework with regards to which rating to go for, and they want to market Hadron with the most powerful single-GPU cards available.  We may find only cards like Titan-Z or R9-295x2 may not work with Hadron's PSU as they really push the boundaries.

    For Intel processors, 0.122 x TDP = Continuous Amps at 12v [source].
