Great Upgrade/Replacement Motherboard 5/26/2020 6:08:23 PM

Pros: Good price for the product.
The overall performance is great.
Love the overclocking and fan control features.
The install was pretty straight forward, no hidden "gotchas".
The LED effects are pretty cool and they go with my RTX 2070 Super's effects.

Cons: Wish it had a few more SATA ports and and extra dual 3.1 (Gen1) connector. These are more "nice to haves" but not deal breakers.

Overall Review: I bought this MB as a replacement when my 8 year old Gigabyte G1.Sniper 3 motherboard finally gave up the ghost. I was originally going to go with one of the Gigabyte AORUS motherboards, but they were a bit pricey. Then I came across this ASUS motherboard and it had most of the same features as the Gigabyte motherboards, but was less pricey. I have used ASUS motherboards in the past and always had good luck with them, so I was pretty confident going with this motherboard. Of course, this also meant a new CPU/CPU fan, and memory as well. One of the best advantages of doing your own build is if you've done your homework and planned ahead, when updates or replacements are needed, you don't have to buy a whole new computer, only what you need. Although, a new motherboard, CPU/cooler, and memory is pretty much a brand new computer. I've had all of it up and running for a couple of weeks now with no issues. With this MB and the purchases that went with it, I wasn't looking for upgrades per se. I was looking more for cost effective replacements. Of course, replacing 8 year old technology with newer, more state of the art technology is an automatic upgrade in my book. Overall, I'm very pleased with this MB, as well as the other components that I chose to go with it.

Great Motherboard, but the having trouble with the AI overclock 5/24/2020 2:40:37 PM

Pros: Great heat syncs on various components
Made my build easy to put together
All the features needed for a gaming PC

Cons: AI Overclocking feature makes my machine crash every few hours (i7-9700k, 2080ti), error messages seem to indicate it's the CPU.
RGB headers are NOT ARGB headers. Minor gripe, seems like everything is ARGB now.
LED1_CON slot, which is indicated in the manual, is covered up by plastic/heat sync/RGB components and not usable.

Overall Review: A great motherboard with some very minor issues. I was a bit bummed the AI overclocking resulted in crashes - it's entirely possible that it's an issue with the CPU, so take that feedback with a grain of salt. The RGB header not being ARGB is a minor annoyance that I just didn't realize I cared about when I bought the board.

best bang for the buck 5/23/2020 11:53:36 AM

Pros: - Every feature for performance
- low price tag
- excellent power delivery

Cons: - no extras like wifi and a included dac

Overall Review: I thought this might be a cheap motherboard with no benefits. To my surprise it has everything for perfomance without the extra stuff you don't need. You get the overclocking ability you need, the color is nuetral, and it has some lighting for added customization. I was very surprise asus didn't skimp on the quality of transistor and included overclocking ability. For a mid ranged motherboard with the performance you need, but don't want the extra nonsense get this board.

Not my best purchase. 5/23/2020 9:37:13 AM

Pros: Looks good low price

Cons: Died after 36 days.

Overall Review: I've used only Asus motherboard (5) over the course of 24 years on my personal builds and this was the only fail. Guess It was bound to happen sooner or later.

QC & CS at ASUS aint what it used to be... 5/21/2020 3:27:05 PM

Pros: It worked, kinda

Cons: Glitchy USB's since the day I plugged it in - would have to un-plug my "ASUS" Cherry MX keyboard and plug it back in to get the keys to work (the lights are the last thing I care about). ABout 2-weeks after putting the computer together and seemed to be working fine I turned it on one morning and it would not boot past the ASUS screen. Got it booting, re-applied all updates, that night I turned it off, waited, turned it back on, and everything seemed fine. Went to sleep. Next morning, same exact thing only this time I could not even get into BIOS.

Now the REAL troubling part - ASUS TECH SUPPORT is through CHAT and was TERRIBLE. After BEGGING the guy for an RMA I finally got one and sent the thing back.

In the interim, I bought something else recommended by a friend. I will use the ASUS for target practice when it comes back.

Never again.

Overall Review: I would NOT recommend this board, period.

Hit or Miss, First one DOA 5/18/2020 1:48:10 PM

Pros: - Absolutely zero issues with the replacement board, hopefully this one lasts like my last three ASUS boards
- RGB looks nice, haven't messed with Aura yet.

Cons: - First Mobo arrived was DOA. Nothing I enjoy more than troubleshooting brand new equipment and taking everything out multiple times.
- Amber DRAM light on the mobo, no display, no USB devices lit up
- Side SATA ports were difficult to get cables plugged in with the limited space in my case

Overall Review: Overall, I eventually received a working board, the excitement of upgrading your system is drained out of you when you hit that power button for the first time and no POST. If you get the Amber DRAM light with no display and no power to the USB devices, most likely, the board is garbage.

I worked with ASUS support, any RAM slot combinations did not make a difference and they told me my RAM was not on the QVL and suggested I try RAM that is on the list, I understand they need to go through all the steps but don't waste much time or money with this step, Luckily I had a friend that loaned me spare RAM that was on the list to confirm it didn't matter which RAM I tried, my original RAM that was not on the list works just fine on the replacement board before I did any BIOS updates. You may need to manually set the RAM speed in the BIOS for non-QVL RAM.
