Biostar has unveiled its latest mini-ITX motherboard for the AMD B550 chipset, the B550T-Silver, which is designed for use with AMD's Ryzen 5000 and Ryzen 3000 processors. The small-sized board combines a simple silver and black aesthetic with decent features including PCIe 4.0 support, Wi-Fi 6, 2.5 GbE networking, and one PCIe 4.0 x4 M.2 slot.

With both NVIDIA and AMD moving quickly away from multi-graphics card setups to single card powerhouses, the mini-ITX form factor has become as potent as as it's ever been for gaming systems. Biostar's latest board, in turn, ticks a lot of boxes for users looking for a reasonably priced mini-ITX motherboard that can harness the power of AMD's Zen 3 processors to create a potent and pocket-sized gaming system/media center with the AMD's cheaper Ryzen chips.

From what we've seen, no X570 or B550 boards currently list support for the latest Ryzen 5000G APUs, which we expect to change once AMD rolls them out onto the wider market.

The Biostar B550T-Silver combines a basic and elegant black and silver color scheme, with plenty of features to be benefited from. There's one full-length PCIe 4.0 x16 slot, with a single PCIe 4.0 x4 M.2 slot and four straight-angled SATA ports, including support for RAID 0, 1, and 10 arrays. On the right-hand side of the board are two memory slots, which can support 64 GB of RAM at speeds up to DDR4-4933. Biostar isn't openly advertising the power delivery system, but we can see it uses one 8-pin 12 V ATX input to provide power to the CPU.

Biostar includes one USB 3.2 G2 Type-C, one USB 3.2 G2 Type-A, and four USB 3.2 G1 Type-A ports on the rear panel. There's an unspecified Wi-Fi 6 interface for wireless networking, and a Realtek RTL8125B 2.5 GbE controller. The board's integrated audio consists of three 3.5 mm audio jacks powered by a Realtek ALC897 HD audio codec. Users looking to build a mini-ITX media system can benefit from the integrated graphics on the Ryzen 4000 APUs through one HDMI 2.1 and a single DisplayPort video output pairing. Finishing off the rear panel is a PS/2 combo keyboard and mouse port. 

At the time of writing, we don't currently have a price for the Biostar B550T-Silver mini-ITX motherboard or when it is expected to hit retail. However, we do expect it to be reasonably priced compared directly to some of the other mini-ITX B550 models.

    Have you looked at the board? Deleting SATA isn't going to buy you enough space. It's the rest of the layout that's the issue. If you absolutely must have two m.2's on an mITX board, there are a couple of B550 mITX models that look decent. Being B550 means the second one is limited to 3.0, although that isn't likely to make much difference unless you have a top-tier drive and games start really using DirectStorage.

    Hell , even the asrock x300 can shoehorn in TWO m.2 slots and thats smaller than mitx . I do feel two slots should be the minimum, regardless of whther Gen3 or gen4. Im a bit worried about BioStars reputation as being the ass scrapings of MB's. Sound output is a bit feeble too

    Every Biostar board I've ever used worked great for me.

    HDMI 2.1 + 2.5GbE... what a time to be alive.
  • raystriker - Friday, April 16, 2021 - link

    Doubt it can do the upper end of what HDMI 2.1 actually promises :|
  • Death666Angel - Friday, April 16, 2021 - link

    What do you mean? Are there certain things that are option in 2.1? I haven't followed it closely. Or do you just mean it won't be able to display playable framerates at the highest resolution settings 2.1 allows?
  • daemontus - Saturday, April 17, 2021 - link

    As far as I know, AMD APUs top out at 4K resolution. So HDMI2.1 is certainly not useless, as you can drive more Hz that way, but you still need a dedicated GPU for anything more demanding. Also, you are most likely not playing 4K@144Hz games on an APU. But feel free to correct me if that resolution limit has been lifted.

    HDMI 2.1 is useful for playing 4K HDR 120 Hz video on a HTPC. The general lack of HDMI 2.1 ports with 300 and 400 series mITX boards is what drove me to pick up an A520 board for my latest HTPC build.

    Is it just me or are the rear IO ports almost comically out of square with the board, which is also bowed? Weird thing to see in a press photo.

    Assuming the thing fits into the IO shield this could be nice to go along with a 5000-series APU like the 5300G to upgrade the heck out of my i3-2100 HTPC. It's too bad they'll probably be out of stock for the next two years.

    It looks like they took the picture too close and then cropped out the rest of the board.

    Usually what you are supposed to do, is zoom in from a distance, so that you reduce parallax effect.
