AsRock B450 Steel Legend Review, Price, Build. Good Or Bad? Should You Buy Or Not?

ASRock B450 was introduced in their Steel Legend motherboards’ back in January 2019. It exhibits an extremely stunning performance as compared to its specified price. People who always have some confusion regarding the purchase of a good Motherboard required for their gaming and are always worried regarding their budget then this motherboard is the perfect deal for them, as it provides a huge lot of features in less amount of money. AsRock really does make some good stuff without spending unnecessary money in the outward showcasing.  

Unlike the brands like MSI/Gigabyte/ASUS where they are usually supplying a ton of free excess software’s and bonuses to attract the customers. If you are on a tight budget but still want real gaming performance, then there is really no need to get anything more than a B450 motherboard. There’s no multi -GPU support. However, they still get the job done seamlessly. Some mid to high-range options of this motherboard also offer decent VRMs.

As far as audio is concerned ASRock B450 is using the Realtek ALC892 Audio Codec. The Nichicon Fine Gold Series Audio Caps as well as the PCB isolated shielding for the audio section of the board can be seen once bought. Here gamers will be able to experience real-time 4K audio, as 4 gold capacitors are also provided, which helps to enhance sound in FPS mode games and leading to a smooth gaming with a quality sound.

The x264 HD Benchmark 5.0 encodes a 1080p video segment into the x264 format. There are two passes with 4 runs each. We average the 4 runs for each pass to give you what you see below. Obviously, higher frames per second is better.

TESTING – Gaming and Video

Gaming performance really depends on what graphics card you will be using. Because graphics drivers and games are updated so often, mostly it is tested running synthetic benchmarks here. We will be running 3DMark’s Time Spy, and Fire Strike. For 3DMark Fire Strike we will be running it at the Extreme and Ultra setting.


Power consumption for a system is of course especially important. To measure power consumption, I used a KW meter. The idle test is taken on the Windows 10 desktop and the load test is taken while running AIDA64’s system stability test with GPU’s enabled. Remember these values are for the entire system.

Queries related to AsRock B450 STEEL LEGEND

  1. Is x570 better than AsRock B450?

The B450 boards offer a single 10Gbps USB 3.1 port, whereas the X570 offers two USB 3.2 ports. As far as m.2 slots are concerned, the B450 boards offer one slot for SATA and NVMe drives, but the X570 has two slots – one supporting PCIe 4.0, hence opening a world of very quick SSDs.

 2. Why is ASRock so cheap?

Some of the ASrock boards are cheap because they have less build quality.

3. Which motherboard brand is best?

Gigabyte and ASUS are most reliable, Gigabyte being optimal in terms of price / features. Black edition boards are durability tested. MSI is next followed by Asrock.

4. Where are ASRock motherboards made?


ASRock Inc. is a Taiwan-based electronics manufacturer that focuses on the development of motherboards, industrial PCs, and HTPCs. ASRock was originally spun off from Asus in 2002 in order to compete with companies like Foxconn for the commodity OEM market.


The real thing is when it comes to lower tier chipsets

(AMD B450, INTEL B365) motherboards are not that exciting. But the first look usually creates an attractive environment for Gamers and RGB lovers. The Black PCB and urban winter camo design on board really goes well together and the silver lining on the chipset heating and the M.2 heatsink look great too. A great RGB lightning and controller software also accompanies with the motherboard.

The new Steel Legend boards ASRock has some cool stability features like the use of 60A power chokes and Nichicon 12K black capacitors, with ASRock’s “Full Spike” ESD protection for the USB, Ethernet, and audio ports enabling our Ryzen 7 3600X processor a 4.5 GHz overclock across all six cores.

The big noticeable differences on a B450 board compared to X470 is that the B450 board is really designed for a single graphics card, having a single PCI-Express 3.0 x4 M.2 slot and less USB ports. People mostly focus on running a single graphics card, a single M.2 drive, so the need of a boatload of extra USB ports are not required. Teaming this board with a Ryzen 5 processor, 20-series GPU, NVMe SSD will lead to the start of a really awesome gaming system!

For those looking at building a Ryzen system the B450 Steel Legend is a solid choice………


  • Sleek design
  • You can overclock on AsRock B450
  • A-RGB lighting
  • M.2 heatsink
  • Price


  • BIOS does not have an easy mode
  • A-Tuning software seems a bit dated
