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

ASUS TUF B450M-PLUS GAMING MOTHERBOARD

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.

FLEXIBLE COOLING CONTROLS

GPU TEMPERATURE SENSING

System temperatures are key to a stable gaming rig—especially GPU temperatures. TUF Gaming motherboards include Fan Xpert 2+ software that's able to intelligently control system fans based upon the input of multiple sensors, including the temperature of ASUS graphics cards.* This ensures that your TUF Gaming system stays perfectly cooled, no matter how long you play.

*ASUS GeForce 700 and later cards supported.

ASUS Performance and Power Saving Utilities Software Window

FAN XPERT 2+

TUF B450M-PLUS GAMING features the most comprehensive fan controls ever, configurable via FAN Xpert 2+ and our award-winning UEFI BIOS.

Ruben mother board 9/16/2020 8:57:43 AM

Good for NAS use 9/15/2020 5:26:34 AM

Pros: - Six SATA ports, when many mATX boards are down to two or four
- Four DDR4 DIMM slots
- It works!

Cons: - I wish it came with a fixed/pre-installed backplate like some of the RoG B450 motherboards have
- Fan control in the BIOS doesn't including a smoothing period (e.g. smooth fan speed over 2 seconds)
- Has DVI instead of DisplayPort

Overall Review: Purchased this motherboard for a Ryzen 3400G powered NAS, and so far it's working great. I like that it has 6 SATA ports, unlike a lot of mATX motherboards these days.

Something unusual is that they still include DVI on this motherboard, instead of the more modern Display Port. In my application where the machine is running without a monitor, it doesn't make much difference. However, it still is odd seeing products shipping with DVI in mid 2020.

Great board, but a little cramped... 9/6/2020 11:10:13 AM

Pros: - More than one fan header, an upgrade from my last motherboard at least
- RGB header as well as RGB on the board itself
- Reinforced GPU slot is a plus, very nice to have
- Ryzen 3000 ready, according to the box. I have a 2600 so I can't attest personally.

Cons: - 2 included SATA cables. I know they're cheap and I could just buy more myself, but I would like to have more included. No biggie though.
- Board is cramped. I used the relatively small stock cooler, the Wraith Stealth, included with the 2600, and the leftmost RAM slot is inaccessible. If I'd installed RAM in it, I wouldn't have been able to put the cooler on at all, more than likely.
- If you use a dual slot graphics card (which you most likely will if you're bothering buying a gaming motherboard), you don't have access to the smaller PCI slot right below the one for the graphics card. This means that you must install an accessory such as a Wifi card on the other full sized slot, which works just fine, but prevents you from using it for other things if you so desired.

Overall Review: I'd recommend this board, but with a few things to keep in mind. First of all, this is a pretty decent board, but it's far from top tier. It seems it's designed more for the average budget builder than the hardcore enthusiast, but if you were an enthusiast, you probably wouldn't be looking at the B450 chipset in the first place. The case fan headers are all kind of in the center of the board, so it's hard to have clean cable management when you plug it in there. I ended up using the molex connectors from my power supply to bypass this issue, but it's something to keep in mind if you want good control over your fan curves and such.
