Great product, but ccl packaging is very poor. They don't even box up the motherboard when they send. I wouldn't use them again. Trying to save money ccl

A really clean board. Supports much faster OCed RAM than by old B450 board. Good accessibility to headers. Well designed. MSI software is great. BIOS is clean and easy to use.

No problems (without having to update bios). Lots of nice features.

Bought for the built in wifi, and that works a treat.

Only just finished our build but so far so good. Haha l am chuffed as in the absence of anyone with a dangly bit between their legs stepping up to do the honours. This computer nurd momma has strapped one on and researched products, bought products and then assembled the products. Thanks to YouTube making up for all the men in our lives being completely useless, so much so they are all getting upper decker flopper stoppers for Christmas to carry their useless man boobs in. A huge debt of gratitude has to go to CSS for the many helpful chats on chatroom helping me with my choices. You have all been brilliant. Over the moon with the results. Let the gaming commence. Highly recommend this motherboard but even more so highly recommend CCS. They can not be Beaton on price or customer care. Will always use them for future purchases. Thank you to everyone who helped xx

Very high quality motherboard. Offers a lot of features which other motherboards dont making it great

Glad I spent extra and went for this premium B450 board, onboard WiFi works well for me even with me being very far from the router, lighting is nice, not had any issues with ports or bios, and AMD have announced support for the next gen of CPUs!

Really good for my Ryzen 3600x

Brilliant quick service


December 2019

Love this motherboard, the built in WiFi is surprisingly good even with the distance to the router, Bluetooth works great with controllers and the colours light up my computer case wonderfully. The MSI app mystic light can be sketchy but it works.


November 2019

It worked well with Ryzen 5 2600 processor. Unfortunately the processor did not support the built in video card. A separate video card has to be used in this combination.

Great piece of kit does everything I need it to and the rgb lights are a nice touch

For the money you won't find a better motherboard with these specs and level of quality, mine is coupled with a 3600 and it's a monster piece of kit !

Tough, durable, looks amazing


July 2019

Pricey for a b450 but good


June 2019

Ordered from CCL via its eBay store. Arrived promptly, nicely packaged, and at the best price I could find online. Great service which I'd happily use again. Product itself is flawless so far. Feels sturdy and high-quality, big chunky heat sinks on the VRMs and chipset, plus an M.2 shield. Wi-Fi works great, ditto integrated Bluetooth. BIOS is intuitive and it's easy to OC both RAM and your CPU. For a single-GPU build I can't find fault with it.

Michael Jones

June 2019

It's a very nice looking board. Easy to install and setup. Simple BIOS with good overclocking features. Plenty of ports for devices and fan headers for case fans. The Mystic Light RGB sync is very cool and works well. Audio quality is excellent, although I'm not a big fan of the Nahimic software included. No other issues with it. All in all a great B450 board.

Cant fault it


April 2019

Came well packaged with all the necessary components to install. Effective after sales support from MSI


February 2019

A great quality product but the XMP profile almost burnt out my RAM.


February 2019

great MB, not used it for overclocking yet. RGB just on the right side of the board not much on the left side.


February 2019

Had been searching for a store that had this board in stock and CCL came to my rescue. Great price and next day delivery. Will use again!
