So Far So Good 8/2/2020 8:03:54 PM

Pros: This Review is for the ASRock review rebate program.
- Great value for a B550 board.
- No issues with install or boot up.
- Paired with R5 3600.

Cons: - XMP profile did not work with my RAM (G.Skill Ripjaws 2x8GB DDR4-3600 F4-3600C18D-16GVK). Had to manually adjust setting to get RAM running at 3534. To be totally fair, this RAM is not on the ASRock qualified list.
- Instructions are pretty sparse - helps to have some past experience.

Overall Review: Been watching for this board since the B550s were announced. So far it has been good, definitely recommend for mid-range gaming build. Hoping for an update to address the XMP issue at some point.

DIDN'T GET the motherboard screws 8/1/2020 1:32:37 AM

Cons: Not sure if not including motherboard screws was intentional or if they just forgot, but they should've mentioned it in the description if it was intended. Really disappointed. I was looking forward to build my own PC today, and now I have to go look for the screws.

Overall Review: I ordered the gigabyte aorus B450 pro wifi for the same price a while back. Didn't have any problems with it. I'd suggest you get the former mobo. At least they seal the motherboard in the packet, not just place it in, and give screws to install.

Great Mobo with B550 capability and Wifi 6 7/25/2020 3:41:44 PM

Pros: Wifi 6 or AC capable.
M.2 running PCI-e 4.0 speed
Reinforced PCI-e x4 16x slot
7.1 Channel Audio (ALC1200 chip)
Ryzen 3000 and 4000 series capable.
M.2 slot for Wifi 6/AC is up-gradable.
Heatsink on the VRM are sufficient.

Cons: M.2 slot is right underneath PCI-e slot for the GPU. I might be bad for cooling your Nvme.

Overall Review: I would recommend this board if you are looking for a B550 board without wanting to spend a ton of money. It has wifi 6 or AC, making it versatile if you don't have ethernet connection by your setup. The M.2 slot for the wifi is upgradable. I also like the addressable RGB slot. Most board only has the regular RGB.

Great board for the money! 7/25/2020 10:59:07 AM

Pros: Great price and warranty feature for feature compared to Asus.
Easy setup

Cons: None

Overall Review: I was looking for the best atx motherboard for the lowest price for a Ryzen 5 3600 processor, 16g memory and an MSI RX 570 8g video card. This one fit the bill. It was easy to set up and everything just works. I tried an ASRock motherboard a few years ago for my wife's computer and it's still going strong.

Great Feature Set at a Budget Price 7/23/2020 2:07:37 PM

Pros: Wifi and Bluetooth Included
Full Size ATX

Cons: ASRock Utilities do not currently work

Overall Review: This review is for the ASRock review rebate program. I upgraded my computer from a Gigabyte B450 D3SH mATX board. Since that board did not come with WIFI and Bluetooth onboard, the adapters raised the overall cost of the computer. This board seems great for the price, with support for PCIe Gen 4 and Zen 3 processors, if I want to upgrade in the future. The only downsides currently would be questions about longevity and durability and that the utilities do not work, but I expect that to be patched soon.
