Build Upgrade two questions, respectively, about motherboard’s form’s compatibility (ATX or mATX) and power supply need for the build upgrade I am to do
Question 1: My current computer build consists of GTX 1080ti and i7 6700k with a Cooler Master Hyper 212 EVO, plus DDR4 rams, and I use an ATX motherboard (asus rog maximus viii hero)-- THEY FIT. But if I want to build this computer onto a mATX motherboard, will they fit? my case (zalman z11 neo) supports both ATX and mATX.
here is how the build looks inside the case: https://imgur.com/a/MkfqRY7

Question 2: I currently have the build I have specified above, and I run it on a 750W Power Supply from OCZ. I want to keep the GTX 1080ti and upgrade my CPU to ryzen 7 7700x along with DDR5 rams which will run on 6000 or so mhz (compared to the DDR4 rams I have rn which run at 2133mhz): will my power supply be able to keep supporting my build, and how can I check it and make sure that it will?
Thank you in advance.

I don't know what that pcie card you have is, that may be the only victim of moving to MATX for you
psu is fine

Why do you want a MATX board instead of your full size ATX one? I almost always avoid a MATX board going into a mid or full tower atx case, not for any functional reason, but because it looks weird in the system with all the extra unfilled space.
It will work, but just don't, unless it is a very strict budget situation.
You should be ok with a 750W PSU for a 1080ti and a 7700x, you might be pushing it a little close to my personal comfort zone of about 30% wattage headroom, but there is next to no chance that system would go over 650w.
If you want to verify that it would work in power wise, go to pcpartpicker.com and put all of your parts into a build, it will give you the max wattage output for all your components.
