Asus Maximus IX Extreme in 7th month

Pros: Got the board last year and still working great. I'm glad I bought the board at sale price $445 with $100 rebate from Asus. It saved me time and money from buying cpu water block separately. The RGB on the board was awesome especially the monoblock. Besides RGB, I was able to overclocked my I7-7700k to 5.0 ghz stable so far.

Cons: dealer sent me an open box when l paid for a brand new item. There were finger prints all over the water block and mobo. Plus I have to modify my case to fit the mobo.

Other Thoughts: ok buy if you get a brand new mobo.

Pros: -Great performance for a ROG standard

Cons: Received motherboard with the chassis motherboard RGB header defective, blue is always on so i never get a pure red (shows violet), or green (shows teal). I did the RMA repair process, they sent it back to me saying they could not replicate the fault. After many calls and "escalations" They want me to tear it down again and send it back for round two. I did not get the quality for the price I paid.

Other Thoughts: would not recommend, find another manufacturer besides ASUS, at the least dont trust their repair process

Pros: Very nice board full of everything you could want. copper and nickel water block.

Cons: Price!

Other Thoughts: On my second board now and I'm still having issues. first board had problem with rgb lighting and flow indicator didn't turn. Second board does not give a reading for outlet temp and flow rate but indicator does turn.
This is very unacceptable for a board that costs 700cdn.
I will have to rma the board again meaning take apart my PC again for the second time. Anyone with a custom water cooled computer or any complicated system can feel my pain!

Cheap water block

Pros: All the listed features

Cons: Aluminum water block

Other Thoughts: I got this during Black Friday for $300 thinking it was a great upgrade for my system. Couldn't find anything online on what material the water block was but was hoping for nickel or chrome. After waiting a week to get a real reply from them, they tell me the water block is made out of aluminum. Even on sale this board is at a premium price and I'm upset that they went through so much trouble to hide the fact that they cheaper out on the main feature of this board! Considering a return since it is so hard to find aluminum fittings for acrylic tubing.

Nothing but problems

Pros: Unique look; All of the features you could want from a motherboard; Rock Solid stable - once it starts

Cons: - Will not post 95 times out of 100.
- Does not support either DTS Connect or Dolby Digital Live over s/pdif. My previous board, the Asus Z170-A, supported DTS. Contacted customer support and they just told me that these features aren't listed on the product page so there's nothing they can do. Thankfully I found a modified version of the Realtek drivers which enabled DDL.
- The integrated I/O shield adds a tiny bit of space between the ports and itself. Because of this, I cannot use the USB type C port as my cables fall out.

Other Thoughts: Won't even get far enough to display an error code. It turns on for about 1 second, the monoblock lights up, then it shuts off. I tried everything, including draining my loop and testing just the motherboard, CPU, and RAM outside of the case - same behavior. Eventually it just started up one time and ran great for 2 weeks straight. Then the next time I had to turn my system off, it refused to turn on again. I'm now outside of my 30 day return period so I'm probably going to have to RMA the board through Asus. These problems are completely unacceptable for a product with a $600 MSRP.

Works Perfect

Pros: This is the very advanced motherboard, You need time andpatience with this as it is not plug n play.
Works great
Lots of fan headers

Cons: Only has 2x USB 2.0 headers, which was problematic for me, since I could not connect my SD card reader from case
Manual needs refining, Tubing installation for monoblock was missing which resulted in an error by me as well as RGB headers of monoblock have a specific way to be connected which was not mentioned.

Awesome

Pros: Monoblock was easy to install. I watched a YouTube video to get it done as the manual wasn't too detailed.
Everything is working just fine from what I can tell. I was able to push my i7 7700k to 4.9 Ghz and RAM to 3600Mhz.

Cons: I wish the PSU connections were not at 90 degree angles. My case is an inwin 303 and the optional power connections for PCIE are blocked. If they were front facing this wouldn't be an issue.

Other Thoughts: I'm getting a Q code of bF. ASUS support says this Q code has not been assigned to anything so I guess the Q code just means there is no issue.
