Three ASUS TUF B450M-PLUS GAMING Motherboards Standing Up, Angled to the Right, One Behind the Other with Yellow, Pink and Blue TUF GAMING Lighting


A solid foundation for building the best AMD Ryzen-based system. This motherboard is powered by the AMD B450 chipset, and supports 3rd/2nd/1st AMD Ryzen processors. Even in its micro ATX form factor, this board offers quad DIMM slots, dual PCIe x16 slots, a PCIe M.2 slot, and six SATA ports—more than enough for you to build a fully-featured, full-power gaming system.

A USB 3.1 Gen2 port delivers 10Gbps bus bandwidth, and a reversible USB Type-C port means you can plug in the cable with either side up. Large heatsinks take heat away from chipset and MOSFETs. This motherboard also has onboard RGB lighting and supports Aura Sync, hence you can customize and sync lighting across a wide range of Aura Sync-enabled components and peripherals, making your build and entire gaming setup really stand out.

Solid motherboard! Really clean. 2/21/2020 4:12:38 PM

Pros: I upgraded my system from a core i5-3330, so to me the Motherboards really clean feels sturdy, The rgb light can be messed using aura sync. Bios is very simple and clean I can use my mouse which is awesome. This is a really good buy for the price and if you get the rgb ryzen cooler it completes this motherboard.

Cons: None really.

Overall Review: I would definitely recommend this to a new pc builder looking for a micro atx motherboard its a affordable price for quality.

Good Board, Mediocre Experience* 2/14/2020 7:39:45 AM

Pros: Board itself is of fair value and clear build quality
Proper accessories included
Nice aesthetic
Fair Price

Cons: *Bios was not updated for 3rd Gen Ryzen prior to shipping so I had to borrow the CPU from my home machine to flash it. This was ordered in December, I really would have like this to have shipped with the current Bios to support 3rd Gen Ryzen whcih was released 2 months earlier.
Usual M-ATX complaints (Layout, pins, etc.)
A few things like WIFI feel like they were cut to differentiate price points vs similar boards.

Overall Review: Purchased as gift for cousin along with all other components as a machine. Aside from the bios disappointment, no major areas to comment. Wifi would have been nice, but USB Wifi is inexpensive and this has enough ports.

Used on budget rig with:
Ryzen 3 3200G (Dedicated graphics card will be a future gift!)
G.SKILL Ripjaws 16GB (2 x 8GB) DDR4 3200
Cooler Master MasterBox Lite 3.1 TG Micro ATX Tower
ADATA Ultimate SU800 512GB SATA-III Internal Solid State Drive
CORSAIR CX-M Series CX550M 550W 80 PLUS BRONZE Power Supply
Pair of Noctua NF-P12 PWM Fans (120mm, Grey)

DOA of this board 2/3/2020 8:37:41 AM

Pros: Got it for a sale price and saved if for a future budget build.

Cons: Pair this with a brand new Ryzen 2700. The case fan will spin and RGB lights on the board will turn on. No video display. No beeps. To trouble shoot, I have tried the two sets of good components (used on other computers) of the following: monitors, PSUs, RAMs, video cards, SSDs, still no dispaly. ASUS has a very thin manual with the board, and no helpful info on the web either.

Overall Review: I have used many ASUS products and been happy except this one. Wish next time I buy and use in 30 days so I could return a DOA product without the hassles of warranty. Wish could give it ZERO egg.

Manufacturer Response:
Dear Valued Customer,

I'm sorry to hear that you are having issues powering on your board with multiple components. ASUS provides warranty coverage in order to fix or repair any product that may stop working prematurely under normal usage. What kind of error tones are you hearing when you try to power on the board. Can you confirm that your monitor is connected to the discrete GPU, and not the motherboard? If you can provide me with the complete system specifications of your build and the error tones you heard, I'd be happy to help you troubleshoot in more detail. Please reach out to me at and include case #N200208629 in your email for reference.

​Thank you for choosing ASUS!

Best regards,

Great dependable little board 1/21/2020 4:51:22 PM

Pros: 1. Comes BIOS ready for 2nd Gen Ryzen, so my Ryzen 5 was plug and play
2. Also has 8pin so ryzen 7 will work fine and with bios upgrade... Ryzen 9, Pauls hardware has great tutorial on youtube... Must install all prior bios upgrades in order one at a time on some boards...
3. On Board LED 5050 12v 3amp 4 pin at top of board allows more LEDs attached to one header but they are all one color at a time (all red, all blue, all green, all yellow etc.) because that's how LED 5050 works, and some onboard led lights (TUF GAMING Logo)
4. M.2 PCIE 4x... Yes Please!!! but it does disable SATA 5 and 6 But whatever.
5. 3 PCIE slots, sort of... Good luck using them all, unless you have a single slot video card, or are using onboard video.... with a Ryzen 3 2200g. But why would you do that?

Cons: The Cons are kind of silly -
There is only one RGB 5050 Header
1. There is no ARGB led (Addressable RGB) - 3 pin header so no rainbows streaming through your case without an Addressable RGB controller
2. After you install a video card that takes up 2 slots... It covers your PCIEx1... Like you were going to use that... LULZ
3. The lower PCIE x16 would be awesome to use for SLI or Crossfire except... There is no onboard Wifi So you either need to use a USB wifi card or plug into that lower PCIE slot with a cool new GIGABYTE GC-Wbax200 2x2 802.11Ax Dual Band WiFi + Bluetooth 5 PCIe Expansion Card... Which will last and last and grab that wifi at screaming speeds.... Unlike onboard video
4. The TUF designation doesn't mean that the board is any more durable than any other board... It just means that it's part of the ASUS Partner program where other venders make compatible products...

Overall Review: Bought the ASUS TUF B450M-PLUS AM4 Micro ATX (open box) here on Newegg for a low cost build for my youngest kid. I knew that he wouldn't be adding a bunch of PCIE cards so this seemed like a great choice. It comes with some LED lights on the board that can be controlled through the ASUS Aura software package. Knowing that it's ASUS, I definitely feel confident that this board will outlive it's use. And since he is 10 years old, he's super stoked that Roblox looks so cool.... I know what a waste am I right? There are cheaper boards out there but this one is pretty slick.

Powred up no port 12/18/2019 9:43:14 PM

Pros: Small and effective for its price

Cons: Mine was defective and have now been eagerly waiting for my new one to be shipped out even though mine has already arrive in California.

Overall Review: Beautiful little board with integrated rgb lights, but Newegg’s shipping policy for it makes it a long process, since they are checking to see if it’s defective (even though I have a 3 year warranty ...) and I already got it tested. Probably won’t arrive for another month due to the holidays

Works as should 12/18/2019 1:06:30 AM

Pros: *rgb works well, they put it in a bad place since my graphics card covers it really well. I didn't even know at first that it was there before buying this but it looks fine I guess

Cons: *I would have liked some more fan headers, make sure you get a hub or splitters before buying this.

*Another USB 3.0 header would have been nice to have

* The audio drivers are possibly the worst thing I've ever used out of my 4 computers I've built so far but I haven't tried trouble shooting so don't take this too seriously

Overall Review: Would recommend. Bios makes over clocking easy for RAM and CPU.
