My Computer:
.CPU: i7-2600k
.Mobo: ECS Z77-A2X Deluxe v2.0
.RAM: 4GBx2 1333
.VGA: GIGA R9-280X rev3.0
.HDD: Seagate 1TB
.HSF: Corsair H50
.PSU: SS 600W ECO
Can my i7-2600k OC to 4ghz (with auto voltage, just change multiplier to x40) ?
 
Solution
The real question is do you have the cooling to take care of the processor as you overclock it. That is what will determine if its stable along with your MOBO and other specs. the PSU should not matter, but after closer examination of your PSU, it only have 2 12v rails at 18 amps each. total of around 35 amps, the card alone pulls up to 25 amps, that leaves the 10 amp overhead in torture testing for your CPU and other 12v draws.
Your CPU overclocked is pulling max like 8-9 amps, I have also been rounding so in the end you will have around 5-10 amps on your 12v rail remaining and you can easily use a small amount of this to OC. but if you are not changing voltage and only frequencies, then it wont pull more power then its allocated...

But most importantly you want to make sure you have a CPU cooler that can handle it, Like your current one if you attached another fan for a push/pull config and set it up correctly you can prob have a good overclocking time.

Im not sure if that MOBO is good for overclocking, when overclocking you usually have to have a mobo as well thats ready for the OC.

Label of my PSU said it has 2 rails +12V with total 46Amps( 24amps each) and My plan is just change the multiplier 34 to 40 (without touching voltage or frequencies). Some OCer said that my MOBO can handle OC, just not as good as GIGA, ASUS or Asrock

Change Multiplier without voltage still increase Wattage and Heat, right?
