- Solid - George, 19 December 2025
It looks good, and it's my first time building, so I may have overlooked some things about it before buying, such as it only having one gen 2 ARGB header, but what loses the star is armory crate. Don't get me wrong, it was great at first, but then it started interfering with signalrgb and had to be deleted. A shame, it wasn't bad. Oh well. still solid though and the free keychain looks cool.
- Asus ROG Strix B-550-F - Armand, 11 December 2025
Good day.
We had a A-520 motherboard with RTX4060, 32gig ram, Ryzen 7 5700 and 750W psu. Very unstable, screen freezes and alot of crashes. Even after firmware updates. With the B-550 motherboard we experiance a 25-35 FSP diffenece and very stable pc. It is worth it to get the correct mother board and you need to make a lot of research, before buy a pc build. I highly recommended, the extra money for this mother board and a good company, like Wootware to purchase it from. I am very impressed with their service and delivery times, especially since I am staying in the Northern Cape area.
You have a wonderfull Chrismas holiday. - ROG 550 - Selvino, 26 July 2025
Very Happy! Thank you Woot!!
Would have been even happier if the box was sealed. Other then that and the bios update I had to do I have no complaints.
- ASUS ROG STRIX B550 Gaming WiFi II ATX Desktop Motherboard - Kobus , 25 April 2025
Motherboard came very well packaged and delivered by the couriers, I am very very happy with this motherboard as my choice for my first pc build! The motherboard has the latest PCIe 4.0 speeds i need for gaming and other things and it is very very attractive to the eye! Thanks Wootware for the excellent service!
- As expected - Simon, 5 March 2025
Amazing motherboard, lost of fan headers, easy to plug in usb headers, and lots of usb ports.
- Everything I Expected - and More - Nick, 20 January 2025
Can't believe the build quality on this Motherboard. Exceptional.
Feature rich and extremely capable.
I will be building more PC's with them for sure. - Great Board, excellent Price - Nick, 14 January 2025
When looking for a all in one Mobo, it was difficult to find one that fit into my budget, and still offered all the required features/specs. Well this board does just that. And at the price, it is in my opinion one of the best Value for Money products on the market. Great Quality, Beautiful look and feels rugged. I will definitely build more systems with them.
- Clean Look - Dale, 29 October 2024
Nice board. PCIe Gen 4 is nice to have, but the best thing is having built in Wi-Fi and Bluetooth. I love the blacked out look, very clean with some subtle RGB. It is a shame there is no type-C header for the front IO, but other than that, very happy. BIOS was updated out the box.
Thanks Wootware for the great service ! - Impressive and Affordable - Tumelo, 17 October 2024
This is my second Asus motherboard, had previously gotten the white version of the board. And it looks good and works just as good out of the box... I didn't even need a bios update, just slotted in my 5800x3D and it just worked. Gen4 nvme works at full speed as well.
So I'm happy... - Great board! - Philip, 17 October 2024
This is my second Asus mobo. I had a lot of Wifi issues with my previous TUF board from the start where I had to downgrade my drivers for it to work (sort of). So far I have not experienced it with this mobo. Very happy
- Robust - Michiel, 8 May 2024
Excellent motherboard, running my 5950X perfectly with an even better under-volt on CPU and RAM than my X370 board did. VRMs can actually be touched now due to the extra cooling. The onboard front panel audio amp can now run my Sennheiser headphones properly.
