I do not plan to overclock in any way.
I am curious to see if these two as a pair would bottleneck me or have any detailed conflictions.
Also have not purchased anything just yet.
Specific MOBO:

(upgrading gpu soon, 1080ti if i can find one)

Thank you.

While you won't be overclocking, you are already losing out on XMP and faster RAM speeds with your 7700k. It seems a bit ridiculous to upgrade from a 7700k to a 9900k when you have so much more performance potential with what you already have.

As already stated, even z370 motherboards are having issues with the power and heat of the 9900k. Using a b360 board would be counterproductive to the point you probably would only see a benefit in the heaviest multithreaded apps and gaming isn't going to be much difference. B360 also continues to handicap you from XMP.

I guess I'm confused why you are buying enthusiast parts with a casual approach. I think your better bet would be to save the money on the CPU upgrade and just buy a quality GPU...
Hi, I would not go the B360m route at all as even at stock the 9900K is power hungry. I would just get one of the base Z390 boards like the $128.49 MSI Z390 A Pro or the Gigabyte Z390 Gaming X which has a phenomenal VRM and all just for $129.00. You also get more USB's and a couple of other nice extra's just for a little money..The Gigabyte Z390 UD£ is just $119.99

The b360 chipset will hit power limits and the 9900k wont be able to sustain its boost. Even though you wont be overclocking, the 9900k basically overclocks itself by the way it boost. So I would get a cheap z390 board and it will be able to run fine out of the box.

Or better yet, save a pile of money and get a 2700x.

Using a cheap MB isn't a good idea, never really is.

MOST people who are having issues are those with cheap MB's, and or don't know what they are doing like a lot of those morons on YT and some review sites.

Then there are some of us who do know what we are doing that don't have issues. ;)

My 9900K is running rock solid at 5 GHz (all cores) on AIR with my AORUS Z370 Gaming 5 and I don't have heat issues.

 


The base Z390 MB's are crap basically, might be ok for the base CPU's, but I wouldn't expect much otherwise.

Better to go with good solid mid range motherboards or better as they have better VRM's and are more stable.

Same with the Z370 motherboards.
 


Better off staying with what you have now if that what's you are thinking about doing.
 


He did state 'no overclocking', and the Gigabyte Z390 Gaming X is more than capable of handling the 9900K even overclocked as are the others if the 9900K is run at stock 95w....
 


Nope, they will pull around 180W.... Even stock...

 
Not sure how to say it, but all the motherboards can run the 9900K at stock and at a watt limit from 95w upwards...You just set the BIOS or Intel XTU to set the power limit...nothing more is required and even then, the boards have been designed to handle the 9900K at stock at the very least. Yes it will limit the 9900K thermally but if all someone wants is to run it stock , no issues..and of all the boards I suggested, my primary suggestion was the Gigabyte Z390 Gaming X with a 10 Phase VRM setup and that will most definitely handle the 9900K.

Also lets be honest, someone buying a 9900K usually will tend to buy the mid to best motherboards to use said 9900K at it's best, in this unusual situation, something I personally would not do, the motherboards in question will run the 9900K, just not to its best...and that's where what you are willing to spend comes into play...
 
While a 10+2 VRM may be sufficient, I personally wouldn't pair a 9900k with anything below a true 12 phase. An 8+2 will struggle to maintain boost clocks.

To say Z390 boards are made for a 9900k is false. They are made for 9000 series CPUs which include the 9600k and,9700k which have very different VRM needs. It's pretty clear that anyone spending the money for an ENTHUSIAST 9900k should pair it with an appropriate motherboard regardless if they are overclocking, this is the best advice. Will any z390 board "work"? Yes, but it isn't the best idea.
