Recommended PSU for OC
Recommended PSU for OC
Hi All
I have a new Psu .- Seasonic M12II-620 EVO 620Watts 80Plus Bronze Full Modular. Can I make a minor OC on my 6600k using this PSU (likely 4.2-4.4ghz)? If not, the next best choice would be the Psu . Seasonic X-650 650Watts 80PLUS Gold (Modular).
I don’t have enough budget anymore, so if my current PSU is fine, I shouldn’t change it. Please advise.
Other parts: mz170a pro carbon, 980ti, gskill 16gb

Thank you. I think I need more research to know whether a 620w can handle my system with a minimal OC.
Just for the CPU, you have no problem. I have lived for few years with overclocked CPU with HX-520. CPU is not that power hungry. even after serious overclocking with unrealistic (synthetic) load, it remains well below 130W.
The exact formula to calculate how much your CPU will draw after overclock is:
OC Wattage = TDP * ( OC MHz / Stock MHz) * ( OC Vcore / Stock Vcore )^2
You're free to push your CPU and GPU to any level of overclocking you desire. It seems you have a fairly good PSU.
Just to clarify, tier two is great. Even tier 3 is decent. A small note.
Because it's a dual 12v rail, I'm uncertain about the maximum GPU overclock you can push. The 980ti has a 250w TDP. Unless your PSU can supply more than the standard 24A to another rail at the cost of others, you won't be able to significantly overclock it, since 12v*24a equals 288w.
The positive side is that the CPU can run freely—it won't exceed 125w even with overvoltage.
Yes.

A small note. Because it uses a dual 12v rail, it's unclear how much you can push the GPU overclock. The 980ti has a 250w TDP. Unless your PSU can supply more than the required 24A to another rail at the cost of the first, you won't be able to significantly overclock it since 12v*24a equals 288w.
The positive side is that the CPU can handle much higher loads without exceeding 125w through overclocking. Thank you. I’ll need more research to see if a 620w system can run with minimal overclock.
