How many watts psu for overclocking

[Lejend]

Here's my rig:
MOBO: sabertooth 990fx r2.0
CPU: fx 8350
GPU: msi GTX 970
PSU: 600watt bronze psu (corsair builder)
Case: Corsair 200r
CPU cooler: Cooler master 212 evo OR Phantek PH-TC12DX_BK ( haven't decided yet, could help me with that too 😀 )

I plan on OC'ing my gtx 970 to as far as possible without increasing voltage. Read it's easy to do this with the gtx 970 and achieve benchmarks equal to that of the 980.

I also plan on OC'ing my fx 8350 to ~4.7GHz (+-0.1GHz)

Will my 600 watt psu be enough ? I'm hoping the really really low power consumption of my gtx 970 will leave me room to OC my fx8350 too. Also, which cooler should I go for out of the ones listed, or similar priced ones, considering what I want to achieve. I do not plan on using liquid cooling.

4.7 Ghz OC on air might be pushing it. Something like 4.4 Ghz is more likely. With a Noctua or similar Phantek.

400-450 watts should be what the system draws from the wall when OCed.

ur psu should be fine dont bank on 4.7ghz tho as some chips are crapper than others never no untill u try tho i was able to get my fx8150 up to 4.9ghz on 4 cores only ran fine but my computers on everday so no need for the big jump. good luck

Figuring out what your OC wattage on your CPU is going to require that you know the OC vcore as well as the clock speed.

OC Wattage = TDP * ( OC MHz / Stock MHz) * ( OC Vcore / Stock Vcore )^2

Example:
Intel i7 2600k
3.4ghz (3400mhz)
1.25v
95 watts TDP

For this example I will use a relatively average overclock voltage of 1.35v to reach 4.5ghz (4500mhz)

OC Wattage = TDP x ( OC MHz / Stock MHz) x ( OC Vcore / Stock Vcore )^2

OC Wattage = 95 x (4500/3400) x (1.35/1.25)^2

OC Wattage = 95 x (1.3235) x (1.08)^2

OC Wattage = 95 x 1.3235 x 1.1664

OC Wattage = 147 (which is exactly what was calculated by the PSU calculator for overclocked CPU watts on this chip)

You can also calculate it in this link, but you still need to know the OC vcore and speed as well as stock vcore and speed.
