    Pros: Seems good in most areas. Cons: About one time in five, the boot stops with the message: “USB Device Over Current Status Detected!!! System Will Shut Down After 15 Seconds.” It has done this since I received it almost two weeks ago. I bought a powered USB hub, but no change. I tried different mice and keyboards, same erratic result. I even tried it with NO USB connections at all to the motherboard, and received the same message (with the expected one about the keyboard being missing)….

    Pros: Overall it’s a good board. Sleek, easy install. Runs well as long as I only populate 2 of the 4 memory slots. Cons: The memory slots: No matter which way I try and flip the sticks around, I can’t get this board to post if all 4 are populated. The 4 pack of 4GB G.SKILL Ripjaws V simply will not post, even with adjustments to voltage and speed in the BIOS. Spent the day looking for solutions and seems that others have similar issues and just walk away, only using the 2 slots. No real fix…

    Pros: -3 big heatsinks for VRM & Chipset -Ryzen 5000 ready -PCie Safeslot slot keeps my GPU straight -Diagnosis LEDs Cons: -No M.2 SSD heatsink -Yellowish LED -Silver stripes (black fits more setups) Overall Review: Overall a good B550 board that could’ve been better, similar boards from other manufacturers have m.2 heatsinks, addressable RGB and nuetral black designs to fit more styles–I recommend those.

  4. Benjamin C.

    Overall Review: Purchased this as a complement for a Ryzen 5700G. Did not work out of the box. Requires a firmware update, which requires an earlier Ryzen CPU. Tried AMD’s “Short-Term Processor Loan Boot Kit”, which did not inform me until after the period where I could return everything that they will not send a CPU with integrated graphics, so they expect you to purchase a dedicated graphics card as well to do a firmware update. Horrendous experience, and I’ve been unable to even test the…

    Pros: Nice ATX Board, it has pcie 4.0 and a lot of userul things Cons: Nothing really it misses a usb c frontal header Overall Review: It came perfectly packed, It is very important for me because Im from other country, so the box, and specially the board came in perfect shape, Asus is a good brand so naturally it ran smoothly, the board has nice effects like white leds.

  7. Domenick

    Pros: Could have been a decent entry level board Cons: Will not boot out of the box with a Ryzen 5000 Overall Review: I know my opinion doesn’t mean much but I’m going to rant a little. I have been a fan of ASUS for quite some time. I have used ASUS motherboards from the ASUS Crosshair IV Formula all the way up to the ASUS Prime X470 pro, tablets as far back as the Asus Transformer, Strix GPU’s, and my Asus 2 in 1 laptop I use almost daily and never had more than a minor issue which was able…

  8. Newegg has all my money

    Pros: Board installed into existing windows environment no problem. No need to flash Bios for Ryzen 5600, plug and play baby! USB-C Connector? Don’t mind if I do. Nice locks on the PCIE connectors, with the connected x16 being a different color for easy identifying. Ram slots as well. Overall it was a pleasure. The bios is easy to use as well, better than what’s on my RoG Strix B350. Wonder if I can upgrade 🤔 Cons: I didn’t encounter any negative issues except one of the pins on the audio…
