I found a guide for you to get started. https://www.tweaktown.com/guides/8481/coffee-lake-overclocking-guide/index.html

What is the full model of your PSU. There are lots of Corsair 850w PSU's. What is the GPU? Are you running two gpu's? Unlikely these days.

So a 1080ti is recommended to have a 600 W PSU. The card itself is 250 W - 350 W. https://www.tomshardware.com/uk/reviews/asus-rog-strix-geforce-gtx-1080-ti-oc,5225-4.html

8700k overclocked too 4.9GHz uses a maximum of 170 watts plus but in the review was throttling, so I would aim for 200-250 watts to be safe at 5GHz (300 watts extra to be sure)

Intel Core i7-8700K 6-Core 12-Thread Processor Review - Page 6

Both Intel and AMD have been locking horns over the last few months, something we haven’t seen on a competitive level for years now. We’ve had Ryzen and Threadripper go head to head with Intel’s…

So a 750 watt PSU or more. So the PSU should be fine if its a decent one.

So, expected overclocks and the chance to reach said overclock.

8700K	4.90GHz	4.70GHz	1.387V	Top 99%
8700K	5.00GHz	4.80GHz	1.400V	Top 83%

Your Z390 aorus ultra motherboard is a great choice for overclocking the 8700k.



5GHz all cores could run hot with your cooler and you may have to delid. https://linustechtips.com/main/topic/915777-nzxt-kraken-x72-running-hot/
