Awful quality 7/7/2020 6:18:47 PM

Pros: - Reasonable layout in a compact package
- One heatsink over the SSD

Cons: - Two SSD slots but only comes with one heat sink. Need to pay extra $$ for second heatsink
- Does not come with TPM chip and have to pay extra $$ for it
- Slot for WiFi antenna in the back is awkward
- Socket pins broke after CPU replacement. The pins on this motherboard are extremely fragile and not made for you to replace or upgrade a CPU. Manufacturer considers it "out-of-warranty" if the pins are broken and would not cover it.

Overall Review: I would not recommend this motherboard.

Manufacturer Response:
Dear Jin,

We sincerely apologize for any inconvenience this may have caused you.
The CPU socket has been covered with protection cap to avoid damage the pins.

Easy to set up and use 7/6/2020 5:43:26 AM

I would skip this one 6/30/2020 6:54:36 AM

Pros: It’s nice looking?

Cons: Bad construction

Overall Review: I purchased this board for a completely new build. After full assembly I could not get it to post. Tested all the additional hardware including the CPU for faults. None found. After some research I found people were having a ton of problems with the memory slots. On this board it would only acknowledge a2. No go on any any slot for a 2nd stick. Many people have reported having this particular issue, only being able to slot a2 and b2, or having it only pick up a 4gb stick on slot a2 with the rest dead. Sorry ASRock but I cannot with good conscience recommend this board for anyone. Folks I suggest spending a tad bit more and going for an MSI, Gigabyte, or Nvidia.

Failed 6/19/2020 1:10:41 AM

Pros: Zero

Cons: The mobo failed the first day.
I'd recommend going with Asus or another reputable manufacture for better quality.

Overall Review: I purchased the motherboard as part of a bargain bundle with a CPU and It seemed like an okay deal because I didn't feel like going all out and spending thousand or more on a full upgrade till DDR5 ram and PCIe 4.0 became fully standardized.
The computer worked fine after assembly, but then it started having issues constantly restarting randomly. My other parts are working properly as they've been used in my previous rig and according to Pcpartpicker there are no compatibility issues, so it is definitely the mobo.
