Okay, so just to be sure, is the 600W power supply enough?
Also, Is overclocking really easy? I've never done if before,
On the build, I changed the Ram, SSD, and re-added the CPU cooler
Perfect!
Corsair is a good quality brand. The GTX670 only needs a 500w psu, and 550 for a GTX680. You are good there. It is not wrong to overprovision the psu a bit. I will only use the wattage that is demanded of it. Running at less than max capacity will keep it's cooling fans at a lower speed.
Intel sells a "K" intending that it should be overclocked. It really is very easy if you will be conservative about it.
I would not use the oc options of the motherboard since they can be a bit aggressive.
Instead, in the bios, just raise the multiplier from 34 in baby steps until you feel comfortable. 40-43 should be ok. Leave the voltage options on "auto"
That may not be the maximum or optimum OC, but it will be easy and safe.
Stress the cpu by running prime95 with rounding checking. Monitor the temperatures using realtemp or whatever.
I would not be alarmed if your hottest core(they will differ) reaches 70c. The max is 105c.
In normal usage, it will be lower than that.
If the cpu should ever get too hot, it will throttle itself for protection.
While testing, run cpu-z. It will show you what multiplier you are currently running at.
During periods of little activity, do not be alarmed if it drops to 16, that is normal.
Let it run long enough to reach maximum temperatures. You should get NO errors.
Enjoy...
