I am very pleased with the purchase. Everything started to work out of the box - used the previous generation of Ryzen, however. Some people may say that it is not compatible with the NEWEST Ryzen lineup, but fear not - there is an option to flash BIOS just with using a USB stick - no older CPU needed. And if you would be in a dire need of CPU to flash BIOS, AMD will lend you one for free. Memory compatibility is excellent - tried some not mentioned on their webpage and it is working like a charm.

Top motherboard in its price segment. Provides similar performance and features to boards which cost 50% more.

A solid board with excellent features. A good price and only let down a little by the quality of the website. Getting drivers was ok but registering the product was a different story.

Always a pleasure in buying from ccl. Very fast delivery as they says 3 to 5 days. Got it in 3 days on the weekend through royal mail. Furthermore the product is great and what you expect from a high end b450 motherboard.


October 2018

Brilliant budget yet feature rich Mobo with solid VRM's, i teamed this with a 2600x and it runs perfectly out of the box and remains cool and stable over many several hours of gaming, with no signs of heat build up. LIghting effects are subtle and not in your face, and its was exceptionally easy to do my first build with. only gripe is i wish it had the same connector block for header pins as another manufacturer as my old eyes struggle with them
