ASUS ROG STRIX B550-A GAMING AMD B550 Socket AM4 - Gerhard, 27 November 2025
1st of all im pleased to say im impressed with Wootwares service. None of the items i bought so far gave me trouble. For the Asus mb i must say its well built and it worked well with Gskill trident 4000mhz, stable no issues so far. Thumbs up!!

Brilliant IO and Quality - Marlon, 12 November 2025
Recently got this Mobo for my partner paired with a ryzen 3600 and 32gb of Ram. excellent quality board with all the IO she could need.
Super happy with this and would definitely buy a second one. -
Super Great Value - Francois, 19 August 2025
I bought this for my server after getting a good deal on a much bigger cpu, this board is so nice I almost wanted to swap it for my main PC's board instead of cramming it in the server, such good value for money and I never thought I would say that about a Strix board
-
WORTH THE MONEY!! - Kira, 25 May 2025
This motherboard has a very premium design filled to the brim with feautures, the bios is clocked with every option and overclocking ability you could need with great rgb software (armoury crate) the vrms cooling is very well designed it supports docp and has rebar for my arc A750 and runs my ryzen 5 5600 very well
-
Excellent Coice - Ancel, 14 May 2025
Happy with the purchase. Board is solid, build quality is exceptional. Running my 5600X like a dream.
-
Solid Performance and Easy Setup - Wouter, 27 November 2024
The motherboard looks amazing and feels solid. It has plenty of ports and slots, more than I expected, and everything just works smoothly. The only thing I wish it had was some RGB lighting on the board itself and built-in Wi-Fi, but other than that, it’s a solid board for the price well worth it.

Easiest transfer MB ever - Brendon, 21 August 2024
I love this board, first time I was able to transfer all my components to a new board without driver issues. The board booted up and autodownloaded all relevant drivers making it the first plug and play MB I've installed.
Slick design with a great companion app to see the PC specs and drivers in one place. -
Excellent motherboard - Brian, 15 July 2024
Truely very happy with wootware and the motherboard. First time service I recieved was excellent. Motherboard is fantastic quality and design. Truely a beauty
-
Love it - Dirk, 4 July 2024
I was going to go with a reallllly cheap AM4 socket for my kid's first PC build but "splurged" a bit on what I thought was a really good deal. Totally worth it. This is just a great motherboard in every way. And it's really pretty to boot. I'm a huge Asus fan generally. Totes worth it
-
Great - Hua, 9 May 2024
Looking great, seeing many saying it doesn't have enough RGB headers, was more than enough, just depends on what you put in it i guess, pump header is a bit awkwardly placed, not sure if its the same on other board, as well as having had to stack the 2 rubber support blocks for the SSD cause just 1 still leaves a big gap between the SSD and support, overall very happy with it.
-
good but not worth the money - Glynn, 3 April 2024
Good board if you want something basic, but it lacks in headers, not many fan headers not many RGB headers also i have a case with USB C in the front and 4 USB 3s,
the board only has 1 USB 3 and no front USB C - dissapointing for ASUS.
Let alone the bios load times on ASUS are shocking
Pretty doesnt mean good. -
Nice* - Barend, 11 October 2023
While it is a good motherboard i had a few issues while building on it, number 1 being the names for the connectors aren't great, it took me a while to decipher where all the case connectors and power connectors were meant to go. Still a great buy though.
-
Very Niiiiiiiice - Brydaen, 18 February 2023
Very good board. Asus makes some of the best boards in general.
If you want to control your entire RGB set-up, you would need to do it through Aura sync, which is not a bad choice.
Overall? Amazing board -
A Great Choice - Lyle, 12 January 2023
Just like the service from Woot and their staff, this board is excellent. Solid features and a great design. Does work well with a black case too. Only issue I had with the board is the ROG logo had some tiny scratches out of the box but it's now covered by the case fan so it isn't that big an issue. Still a great choice

Asus rog strix b550-a - Damian, 12 January 2023
i am extremally happy with my product and the service i received from Wootware,they answered all my questions and helped when i could not track my order,excelent service
-
Awesome Motherboard - Nishay, 11 January 2023
Upgraded from a b450 aorus elite, and I'm loving the new board, looks and works great. Love the accessories that come with, like the rog stickers and keychain. Packaged securely, and delivery was quick, woot woot!
-
An upgrade - Anthony, 21 October 2022
I actually came from a B450 board to this. This has PCIe gen 4, better memory support, plus this looks fantastic! These pictures look white but its more of a matt machined metal look which really looks fantastic in person.
-
Great all-round MoBo - Kyle, 19 October 2022
I love the black and white theme of the motherboard. No on-board RGB, which is fine, but there is only a single A-RGB header, which means you'll definitely need a splitter.
The lack of USB-C for front port is a bit of a letdown, but other than that, it's running smoothly with my 5800x. -
So Happy - Gareth, 15 July 2022
What an awesome choice, clean and good looking and well performance, once again thank you WootWare !
-
Good - Herman, 29 June 2022
Perfect for 30-series gpu's with 4th gen pcie slot and supports my cpu well.
-
Excellent - ABDUL, 19 June 2022
best choice I could make, coupled with my 5600x...runs like a dream, brilliant audio and no need to manually install any drivers once inside windows ,ASUS automatically picks up the internet and updates what's needed.
