Amazing motherboard and I have no doubt of customer service from Asus (USA) 5/17/2020 11:14:55 AM

Overall Review: This is fantastic CPU waterblock for a unit design from Asus. The waterblock come with leak warning sensor around the liquid fitting.
This is my first build with factory CPU waterblock and it was easy after read the manual and follow the step. I am disagree someone blame Asus when who mess-up and not follow the RMA instruction to send out defected item for repair. I had excellent experience with ASUS (USA) customer service (RMA) and live chat associate. They did excellent and professional job.
My device was fixed and return to me (of course I am patient wait for their detail diagnose entire system but not just what was my issue).

Nice products but...don't count on the rebate or game code 6/27/2019 8:28:47 AM

Pros: Nice product and many features.

Cons: Just getting around to doing this build.

Overall Review: I thought the rebate process was taking a long time, but I had to check to see that my rebate was declined due to not being received. Of course I completed registration and mailed required form and upc/sn the day after. Not sure who "lost" the letter that I sent, I'd be curious to see the number of lost rebates vs the number of lost pieces of postage as I'll hypothese that rebates are "lost" more.

It would have been nice to have been notified that my rebate had not been received about two weeks before the period ended! But that doesn't help because I sent in the ONLY original UPC.

Another thought is that we live in a digital age and Asus knows what SN Newegg had been sent and Newegg knows this too along with my invoice number, why do I need to send in a piece of paper?

I would recommend that anyone sending a rebate of a substantial amount to them, to send it certified. I'm going to say this would still be an issue of contention because they could always deny it for some other reason.

I threatened and should have just sent it back when I couldn't redeem the BO4 game code (the newegg code sent to you was not a game code but a code to send to Asus to get a GAME CODE???, but this is another 1500 word post). Yeah, try to get support from Newegg for this.

Anyway, now I spent $50 than I thought I was spending on this motherboard.

So enjoy my $50 forced contribution to your bottom line.

Pros: the water block is cooper and stainless ,not aluminum

if you dont use water block you dont have any heatsink for VRM and M.2

Overall Review: i recommend this mobo for who have 7700K,
160 for a flagship mobo is worth

Asus Maximus IX Extreme in 7th month 6/17/2018 1:43:14 AM

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.

Overall Review: 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.

Overall Review: 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!

Overall Review: 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 12/29/2017 1:55:27 PM

Pros: All the listed features

Cons: Aluminum water block

Overall Review: 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.
