Smart and sleek entry board - Michiell, 9 August 2022

Found this board, love its look and the price I could get it for. The board feels premium and the parts are good, it has 4 dimms that can support up to 3200mhz ram sticks, it's got all the bits and bobs you'd want for syncing rgb, controlling fans, most extras I don't even use myself, the bios menus are very clean and easy to navigate. All of the design to me is tastefully done and does not feel overdone and gimmicky, tons of ports too. I'd only knock it on the upgradeablity you may find that higher spec components cannot be used to their full potential on this board. I still love it for being a good looking and capable board for its price.
Great service and Delivery times - Schalk, 6 December 2021

Service was great.
Order was placed on Friday and Delivered on Saterday !

Install was simple and easy MB worked perfectly out of the box.
Overclocking works with no issues and Bios was updated.
Looks and feels like a good quality MB as this is my first Asrock MB
Great entry level mobo - Rico, 4 March 2021

Very well priced entry level board, has everything you need to build a really nice gaming setup for an affordable price. pair this with a Ryzen 5 1600 AF and a decent gpu, and you have a setup that can run most modern titles no problem.
Tons of features for the price - Artem, 14 January 2021

This motherboard provides room for 4 sticks of RAM, two M.2 drives (albeit only one of them with NVMe), RGB and ARGB connections, inbuilt RGB, and heatsinks solid enough for overclocking, all at a very generous price!
This board is honestly a good example to any motherboard made for gaming, and the only bad thing about it is that based on recent news, it won't be compatible with the next generation of Ryzen chips. But if the Steel Legend (or equivalent) for the AM5 socket is the same quality as this, then I have no problem recommending it.
Awsome service - Jacques, 9 January 2021

This motherboard looks awesome with its RGB
Amazing! - Leandro, 17 December 2020

Great and fast service! I haven't used my motherboard yet, I must still save for the rest of the parts which I will most definitely order from Wootware again! Thanks Wootware.
Solid Steel - Shane, 8 December 2020

This board is really solid and has all the bells to make working with it great. Simply bios, easy to understand menus, in all just all round great. ASRock has done well and the support from Woot has been great as well.
ASRock B450M Steel Legend - Gift , 17 October 2020

I love the fact that i can have a max of 4 RAMs on this motherboard, it also supports 2 M.2 SSD, it was suitable for my budget, and the RGB LED lights were a bonus. it works so great with my Ryzen 5 2600.
ONE OF THE BEST B450 BOARDS - Ntando, 21 September 2020

The best decision I have made to get this. I haven't been using this motherboard for a long time, its probably been only a week. But It's really a great board with great performance and really cool esthetics to match.
Fast Service and Works Great - Christopher, 24 July 2020

Great Micro-ATX Motherboard for my new Ryzen 3000 build. Delivered quickly and service was responsive and kept me informed. Polychrome RGB sync is a nice extra for syncing my fans and lighting.
