Will a 600W PSU be okay to overclock 8700k (with 1080ti?)

[tigerchung8]

I’m getting an i7 8700k soon paired with my 1080ti. My PSU currently is EVGA 600 B1, 80+ BRONZE 600W. The question is, will this be okay for overclocking my cpu? I also have an ASRock z370 pro 4 motherboard on the way.

Thanks!

The system requirements for the GTX 1080Ti is a 600 watt power supply and a 6-pin and 8-pin PCIE power cables. So it does meet the minimum requirements. But a 650 -750 watt power supply would be my suggestion.

OC 1080 ti can draw up to 320-350W, an oc 8700K can draw 130W. For best operating conditions you should get a 700W PSU. Your current PSU can hold the configuration but it will put a high load on it if you use your cpu and gpu to 100%. On short, yes you will be ok but try in the next 3 months to change it to somethign with at least 700W good quality PSU.

Here are two that I would recommend. Both have a 750 watt version as well.


EVGA SuperNOVA 650 G3, 220-G3-0650-Y1, 80+ GOLD, 650W Fully Modular,

The GTX1080Ti has a TDP of 250W max. Theoretically it only needs the 150W 8 pin PCIe and 75W PCIe slot to run. The i7 8700K is 95W TDP.
So 345W for the 2 biggest items. I wouldn't buy another PSU unless you have some kind of issues. Even if you push your CPU to 160W you shuold still be OK.

Newer CPU, and GPU don't consume power the way older stuff did.

GTX1080TI has a 6 pin and a 8 pin that means 150+75+75, lets not say my 1080ti strix has 2x8 pin. From real facts my 1080ti STRIX OCed 80Mhz core and 200 mhz memory has a tdp of 320W and mine is a very bad overclocker, others can do much more then mine. 95 tdp is theoreticall consumtion for 8700k, mine has 140 tdp but in reality oced to 4.4 has 295W. Dont take the numbers provided by intel and nvidia as absolute truth, they are not.
For example here are some real numbers of consumption for an OCed 8700k:

It depends upon the manufacturer of the GTX 1080 Ti. The power requirements were for the EVGA GTX 1080 Ti. The Asus GTX 1080 Ti for example uses there own board , so it can have slightly different power requirements (two 8-pin PCIE cables instead of one of each). And there are others that use a custom board for their GPU . So it is always a good idea to check the specifications for a specific GPU.
