White-accented ROG styling on the AM4 platform that refuses to die
Quick Specs
- AMD B550 chipset on socket AM4 for Ryzen 3000 and 5000 Series processors
- Four DDR4 DIMM slots with dual-channel memory overclocking
- ATX form factor with white and silver ROG Strix cosmetics
- PCIe 4.0 x16 graphics slot and PCIe 4.0 M.2 storage
- 2.5 Gigabit Ethernet with SupremeFX audio
Still the value king for a Ryzen 5000 build
AM4 is mature rather than obsolete, and that maturity is exactly why it remains popular in South Africa. DDR4 memory is cheap and plentiful locally, Ryzen 5 5600 and Ryzen 7 5700X3D pricing is excellent, and a B550 board like this gives you PCIe 4.0 for both GPU and NVMe. The Strix B550-A Gaming adds the things that separate a good board from a cheap one — solid VRM cooling that handles a 5800X3D without throttling, 2.5GbE, decent audio and a BIOS you can navigate. If you are building a strong 1080p or 1440p gaming machine on a controlled budget, this is a sensible foundation.
What this platform cannot do
AM4 is a finished socket — there are no new CPUs coming, so the Ryzen 5000 series is where the upgrade path ends. Memory is DDR4 only and cannot be reused in a future AM5 build. This particular model has no onboard Wi-Fi, so plan for a cable or an adapter. B550 also does not support PCIe 5.0 or the newest USB4 standards. If you want a platform you can still be upgrading in 2029, spend more now on an AM5 board with DDR5 instead of buying into the end of AM4.
FEATURES:
- Reinforced VRM with heatsinks sized for Ryzen 7 and Ryzen 9 5000 processors
- PCIe 4.0 support for graphics and primary M.2 NVMe storage
- 2.5 Gigabit Ethernet for lower-latency online play

- Aura Sync addressable RGB headers and comprehensive fan control

Why ASUS?
ASUS supported AM4 through more BIOS generations than most of its rivals, which is precisely why a B550 board bought today still boots the newest Ryzen 5000 chips without drama. Every ASUS motherboard from AZonline is genuine stock carrying a 3 Year warranty.

Questions
Before you buy
Which processors fit this board?
It takes AM4 processors on the B550 chipset. Socket and chipset together decide what will run: the socket has to match physically, and the chipset decides which generations on that socket are supported. For a chip released after the board, check the manufacturer’s CPU support list to see whether a BIOS update is needed first.
Which cases will this board fit?
It is ATX. A case supports its own size and anything smaller - an ATX case takes ATX, Micro-ATX and Mini-ITX boards, a Micro-ATX case takes Micro-ATX and Mini-ITX. Each case we sell lists the board sizes it accepts under Specifications.
What memory does it take?
DDR4 across 4 slots, up to 128GB in total. DDR4 and DDR5 are not interchangeable - the notch in the module is in a different place, so the wrong type will not seat. Buy the memory as a matched kit rather than as single sticks wherever you can.
Is it in stock, and when will it ship?
This one is out of stock at the moment. Stock does come back in - WhatsApp us on 079 491 0181 with the model and we will tell you what the supplier is showing and let you know when it lands, rather than leaving you to keep checking the page.
What does delivery cost, and how long does it take?
We deliver by courier anywhere in South Africa, and delivery is R180 on orders under R2 500 and free on orders of R2 500 or more. It takes 1-3 working days to Johannesburg, Pretoria, Cape Town, Durban and areas within 100km of them, and 2-4 working days to areas more than 100km from a major centre, counted from the day the order is dispatched. Need it sooner? Express delivery is 1-2 working days for R210, or R150 on orders of R2 500 or more - choose it at checkout. We do not ship outside South Africa.
Can I collect instead of having it delivered?
Yes. Collection is from 11 Voortrekker Avenue, Edenvale, Gauteng, by arrangement - message us first so we can have the order picked and waiting. We are open 09:00 to 16:30, Monday to Friday.
What warranty does it carry, and how do I claim?
The warranty period for this product is listed at the end of the Specifications section above. Claims go through us, not the manufacturer - contact us with your order number and a description of the fault and we will handle it from there. Separately from any warranty, the Consumer Protection Act gives you six months from delivery to return goods that are defective, unsafe or not fit for their intended purpose.
What if I change my mind?
You have 14 days from delivery to change your mind - longer than the seven days the Electronic Communications and Transactions Act requires. The item needs to be unused and in its original packaging, and we pay the return shipping. Refunds go back to the payment method you used, within 30 days of the return reaching us.
How can I pay?
Payments are processed by Stitch. At the last step of checkout you are taken to Stitch’s secure page to pay, and brought back here once it is done. Your card details are entered on Stitch’s secure, PCI-compliant page and never touch our systems.
