Note! -it does come 5000 Ryzen ready (mine did at least when I bought it in January if 2022.) so long as you order from Amazon it’ll be the most updated BIos and you’ll be fine. -Bigger NOTE! YES it does come with Type C, it’s on the back of the motherboard so you can plug 1 type C connector to this board. And YES it does technically have the header on the right side of the board next to the power pins for type C HOWEVER!!!!! It is not usable out of the box! If you plan to plug it into a Type C format IO panel on a case like the one that the Corsair 5000D has you’ll be diss appointed. These models for what ever reason do not come with the metal adapter that goes on top of the header to connect a USB type C. You can buy it on Amazon for 8$ but be warned. I couldn’t find this information anywhere online. -final note , you loose 2 USB slots in the back as one is meant for Bios flashback and the other is for bios update so you can’t use them I tried already and nothing will read. Kinda dumb but it is what it is. Still has plenty USB connectors for what you’ll need. Review : This is by far in my opinion the best looking white motherboard you’ll find on the market. Compare to the prime Z what ever bird that has the little rgb on it this looks way better. This has that metal white and silver look to it that reflects RGb in the case to beautifully. It’s the center piece of my PC and just looks amazing. For price and looks it’s on point. The build quality is top tier and it should be for an ROG STRIX. It games fantastic and I’ve had no issues so far related to the board itself with gaming or any practical use of it. There’s even cute little indicated lights on the right side that show the status of your system if there’s an issue it’ll let you know. ... show more

I bought this to use a TrueNAS server and it works PERFECTLY for that with Seagate EXOS drives (6 of them) with 1 NVMe. The board looks great too and would work well for gaming and is very stable as a development/design workstation. I paired this with 64GB of RAM and a Ryzen 5700G

    • Don't quite know what to say

I ordered mid January and put together my upgrade with my 5600x and 3060Ti. Worked flawlessly for months...then it just stopped one night in late May. System was in sleep mode, and when I clicked the mouse so I could just turn it off for the night, the whole system shut off. Would not power on after that no matter what I did. I thought maybe it's my PSU and replaced it immediately, and it did not change anything. I brought it to my local repair shop for a bench test, and they said they couldn't get any power through it either, but both my CPU and DRAM were perfectly fine. GPU also worked fine, as when I got home I had to replace my whole system back to my old spec with my B350 and Ryzen 1600 just to be able to use my computer. Don't know what to say...it shouldn't just FAIL after 4 months of gaming use, should it? I never OC'd anything, just used stock PBO and kept my system updated...waiting to hear back from ASUS for RMA. Edit: No hassle from Asus for the RMA. Got a new board sent out to me inside of a week from when they received it. Took a bit to set up, but back to tip top shape. CPU running below 65 C on full load, all core. ... show more

This ASUS ROG Strix B550-A may not be the newest model, but it handles everything I need without issue. Installation was straightforward, and it feels very solid and well-built. It supports all my components nicely, and I haven’t run into any compatibility or performance problems. Even a bit older, it’s still a reliable choice for a strong AMD build. ... show more

Basically Identical to the ROG Strix B550-F Spec wise and $10 cheaper to boot. Love the White/Black look. Runs cool. ARGB header works fine and ram RGB worked. I mistaken thought it had RGB on the logo and chip set heat-sink but it does not. Overall pleased with look and performance for the price.
