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’ve used this board for a couple builds. Have it in my personal build. Ran it with a Ryzen 7 3700, then upgraded to a R7 5700x (just make sure to do a fresh wipe when upgrading processor if you do. My computer was super buggy before a fresh OS install)

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.
