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 wanted the new 670 chipsets but saw so many bad reviews for them. I decided to go with this beautiful board instead and am happy I did. I needed somethign that was going to supply stable voltage for the long run and give me enough feature options for expansion of m.2 drives. This was a great option to cover all my needs. ... show more

    • Perfect motherboard for a mid-range setup
Style: ROG B650-A|DDR5|PCIE 4.0|M.2 x3|WiFi 6E
Looking for a good motherboard for your mid range setup? Not ready to fork over the money for that X870E? Need lots of USB ports? Here, my friend, is your motherboard. Now, is it a tad expensive? A little. But it's worth it. It's quality is absolutely amazing, and you can feel just how well made this thing before you take it out of the static bag. The pins are all labeled and easy to identify. And for all you storage lovers out there -- 4 SATA/HDD ports and three SSD ports, with one handling your Samsung Gen 5! There's also a ridiculous amount of RGB headers. I forgot how many there were exactly, but I think there's like four or five. Don't quote me on that one. Anyway, plentiful for your case fan needs. Also, integrated IO shield. No tearing apart your shiny new build to pop it in after you forgot! Of course, there's gonna be cons: Yes, the other reviews aren't lying. Booting up takes a hot second, around 20 seconds, give or take. For me personally, it also started throwing codes when I installed my AIO, but that was fixed with some BIOS settings that took a bit to find. Personally, I think it should change that automatically when detecting an AIO, but who am I to tell ROG what to shove into their motherboards? Now, what about overclocking? I don't know. Being honest, I'm no overclocker and baby my computers. That's for you to take the journey to discover! Overall? It's a solid motherboard. Are there better ones out there? Of course there are! But if you're looking to build a mid-range computer, this one right here is a good pick. Happy building! ... show more

    • ASUS is the GOAT of motherboards
Style: ROG B650-A|DDR5|PCIE 4.0|M.2 x3|WiFi 6E
Review Image by Lawrence D Lawrence D
The ASUS ROG Strix B650-A Gaming WiFi 6E AM5 motherboard offers an exceptional balance of features and performance for anyone looking to build a Ryzen 7000 system. Right from the build quality, it's clear that this board is designed for gamers and PC enthusiasts who demand high performance and aesthetics. One of the standout features is the WiFi 6E connectivity, which ensures blazing-fast wireless speeds with the latest standard, perfect for both gaming and content creation. The AM5 socket future-proofs your build for the latest Ryzen processors, making it a solid choice for years to come. Additionally, the motherboard offers PCIe 5.0 support, ensuring compatibility with next-gen GPUs and SSDs. The BIOS options on this board are comprehensive and easy to navigate, whether you're an experienced overclocker or a beginner. ASUS's BIOS interface allows for fine-tuning every aspect of performance, with excellent fan control, overclocking features, and memory tuning options that take full advantage of DDR5 RAM. For anyone into custom tweaking, this motherboard provides a seamless experience. The audio quality is also noteworthy, delivering crisp, immersive sound, making it ideal for gamers who want a premium audio experience without an external sound card. The only minor issue I’ve encountered is with the front IO USB-C connection. I haven’t been able to verify if it's fully functional on my board, though I'm unsure whether the problem lies with the motherboard itself, the drivers, or my case's wiring. It’s a small question mark in an otherwise outstanding package. In conclusion, the ASUS ROG Strix B650-A Gaming WiFi 6E is a fantastic motherboard, packed with future-proof features, great performance, and excellent BIOS customization options. Aside from the uncertainty regarding the USB-C front IO, it’s an outstanding choice for any Ryzen 7000 build. ... show more
