AI Verdict
A rock-solid, no-frills AM4 motherboard that's perfect for budget builders rocking a Ryzen 5000 series CPU, provided you don't need built-in Wi-Fi or high-end audio.
This board is a perfect match for a standard Ryzen 5000 gaming rig, but the lack of Wi-Fi and 1GbE LAN means you might need to buy expansion cards. It pairs flawlessly with a 5600X or 5800X3D, but falls short if you need modern networking standards out of the box.
If you need wireless connectivity, look for a board with built-in Wi-Fi 6 or grab a reliable PCIe Wi-Fi card.

Pros
- VRM thermals easily handle 8-core Ryzen 5000 CPUs without throttling
- Pre-installed I/O shield makes case installation significantly less annoying
- Includes a physical Flash BIOS button for easy updates without a CPU installed
- Features a front-panel USB Type-C header
Cons
- Uses an older Realtek ALC892 audio codec instead of the newer ALC1200
- Only features 1 Gigabit LAN rather than the 2.5GbE found on competitors
- Lacks built-in Wi-Fi and Bluetooth entirely
- Built on a 4-layer PCB, which is less ideal for extreme memory overclocking
Dimension Scores
Hardware Unboxed testing showed the VRM easily handles 8-core CPUs without thermal throttling.
Includes a pre-installed I/O shield and BIOS flash button, but lacks Wi-Fi and uses an older ALC892 audio codec.
Features dual M.2 slots, but the second slot shares bandwidth with the lower PCIe slot and gets disabled if both are used.
MSI's Click BIOS 5 is widely praised by users for being intuitive and easy to navigate for memory tuning.
Best For
- 1080p/1440p gaming builds using Ryzen 5600X or 5700X3D processors
- First-time builders who want an easy-to-navigate BIOS and pre-installed I/O shield
- Upgraders reusing older DDR4 RAM and AM4 coolers
Not Recommended For
- Users who need wireless connectivity out of the box
- Audiophiles relying on motherboard audio for high-impedance headphones
- Extreme overclockers pushing Ryzen 9 processors to their limits
Watch Out For
- The Flash BIOS button is notoriously picky—your USB drive must be formatted to FAT32 and the file strictly renamed to 'MSI.ROM' or it will just blink endlessly.
- Populating the second PCIe slot disables the bottom M.2 slot due to shared bandwidth limitations.
- Because this is an Amazon Renewed unit, you might not receive the original SATA cables, manual, or crucial M.2 standoff screws.
- The 12V RGB header is located at the very bottom edge of the board, making it a tight stretch for top-mounted AIO cooler cables.

What Buyers Say
The pre-installed I/O shield is the most frequently mentioned perk, saving builders a massive headache during case installation. VRM temperatures are a pleasant surprise, easily handling chips like the 5800X3D without breaking a sweat. The lack of built-in Wi-Fi catches many first-time builders off guard, forcing them to buy aftermarket PCIe adapters. The biggest recurring headache is the BIOS flashback process, which is incredibly strict about USB formatting and file naming. As a renewed product, missing M.2 screws are a nearly universal complaint.
“Great board for my 5600x but I spent 4 hours thinking it was dead because the bios file wasn't named exactly MSI.ROM on the flash drive!”
Common Praise
- VRM heatsinks are massive and keep temperatures well below throttling limits
- Pre-installed I/O shield eliminates the most annoying part of PC building
- MSI Click BIOS is intuitive for setting XMP profiles and fan curves
- Debug LEDs are a lifesaver for troubleshooting RAM or CPU seating issues
Common Complaints
- Flash BIOS button fails silently if the USB isn't formatted exactly right
- Bottom M.2 slot gets disabled if you plug anything into the lower PCIe slot
- Renewed units frequently ship without the tiny M.2 standoff screws
- Audio quality from the ALC892 codec is noticeably flat on high-end headphones
Ownership Tips
- The chipset heatsink gets surprisingly warm, but it doesn't affect system stability.
- You'll likely need to buy a cheap pack of M.2 screws from Amazon before you can install your storage.
- The Dragon Center software is bloated; most users recommend uninstalling it and managing RGB through third-party apps like SignalRGB.
Frequently Asked Questions
Will this support a Ryzen 5000 series CPU out of the box?
Most renewed boards ship with an updated BIOS. If it doesn't post, you can use the Flash BIOS button on the rear I/O to update it using just a USB stick and power supply.
Does this motherboard have Wi-Fi or Bluetooth?
No, it has neither. You will need to buy a separate PCIe Wi-Fi card or a USB dongle if you can't use an Ethernet cable.
Can I run two M.2 NVMe SSDs at full speed?
The top M.2 slot runs at PCIe 4.0 speeds. The bottom slot is limited to PCIe 3.0 and will be disabled if you use the bottom PCIe x16 slot.
What comes in the box with a renewed board?
Expect just the motherboard in an anti-static bag. You likely won't get SATA cables, the manual, or extra M.2 screws.
Is the 4-layer PCB a problem for gaming?
Not at all. While 6-layer boards are better for extreme overclocking and PCIe 4.0 signal isolation, this board's VRMs run cool enough to handle any standard gaming workload without issue.
Buying Guide
When buying a renewed AM4 motherboard, your biggest hurdle is usually the BIOS version. You need to be comfortable using a USB drive to flash the BIOS before installing your CPU. Remember that 'renewed' usually means 'bare board'—don't expect the fancy stickers, manuals, or cables that come with a new unit. Check your case to ensure you have good airflow, as this board uses a 4-layer PCB which can retain a bit more heat than premium 6-layer alternatives.
AMD B550 Chipset
This is the brain of the motherboard. B550 gives you modern PCIe 4.0 speeds for your main graphics card and top storage drive, without the noisy chipset fans of the older X570 boards.
Flash BIOS Button
Think of this as a rescue button. If the motherboard doesn't recognize your newer CPU, you can update its software using just a USB stick and a power supply—no older CPU required.
Realtek ALC892 Audio
This is the built-in sound card. It's an older, basic model that works perfectly fine for standard desktop speakers or USB headsets, but won't drive expensive studio headphones very well.
Alternatives
If you need built-in Wi-Fi or better audio, look for B550 boards with 'WiFi' in the name and the ALC1200 audio codec.
