[SOLVED] 750 W enough for this build?

Considering a 750 W for 2080 S + 9900k. Various calculators have told me this power usage is enough, but some have told me it isn't. I'm not sure what to think.

Also any comments/suggestions on this intel/nvidia build are appreciated.

Yes that is plenty. If anything a 600 Watt will be the minimum requirement you'll need. You shouldn't even get to 70% full usage of that power supply, which is a good thing in regard to power use efficiency curve. Essentially if you're utilizing anywhere from 20-80% of a PSU's max power draw you will be within the highest power to performance efficiency.

You are looking at a cpu that has no issues pulling 250w with a all core 5Gzhz OC, or over 200w stock. Paired with a gpu that in some versions can pull 300w by itself. Add in another 100w for everything else and you'll he pushing a pc capable of @ 650w max watts and 70% of that in heavy gaming loads.

I'd strongly advise a good quality 750w - 850w for that combination, whichever is the better deal. You can run it on a very good-excellent 650w but you'll be looking at possibly hitting 100% loads on the psu if you do.

Gotta say the psu chosen is very appropriate for the build and one of the best psus around.

My normal rule of thumb is to always have at least 50-60% more power than the calculators think I need. So for your estimated 470 watts a 750 watt power supply should be fine.
