Possible to replace Intel I5-9400F with I9-9000KF?

[Torleifelg]

Hello! I want to upgrade my CPU from an intel I5-9400F to an Intel 9-9000KF. I have found that the H370 chipset supports this with a BIOS update. Is this accurate? I am also curious if the power supply is strong enough to support such an upgrade. I tried to calculate the total amount of power usage and found that it should work, but I can not be sure and I am hesitant to spend the money before I am certain.

Also; is the stock intel cooler the same for both Intel processors since they go on the same socket or would I need to buy a boxed CPU? 

The reason for the upgrade is that I am often running calculations that is making the CPU run at maximum capacity for a good while (30min or more), ending with the software crashing. One example is if I place a (Heavy) formula in an excel sheet with more than 50K rows (I realize I can use VB, but I use this as an example)

Some relevant information 

Max TDP for Intel I5-9400F is 65[W]

Max TDP for Intel I9-9900KF is 95[W] 

Both use socket 1151 LGA 

My Motherboard is a Berks 884C (HP) Coffee Lake, H370

I think (but I am not sure) that my power supply is 400W 80 Plus Gold (or somthing like that )

Thank you in advance for the help!

Hello
for the moment we cannot answer your question
Look at the specifications of your computer, and motherboard!

The information is false and or missing
It's just mention this

Besides, there are other processors, as for your model.
I don't have time to compare everything, but at best I found this

Thank you for the reply!
I have looked at the computer and motherboard specifications without becoming any wiser since the maximum TDP of the I9 is 95W.
The Intel I9-9900KF specifications say that the CPU will work with H370 chipset, but the BIOS would need to be updated.

Check yourself, there is an update which indicates support for the processor, but for the i7 only

F.22 Rev.A

Fix and enhancements:

-Added the support for Intel CFL i7-9700 processor

so for the moment, no solution here

I did not notice that Version F.22 Rev.A "Added the support for Intel CFL i7-9700 processor"

Thank you for your help:)
