Prime B350-Plus AMD B350 (Socket AM4) DDR4 ATX Motherboard

Mainstream-Motherboard (ATX) from ASUS, AMD B350 Chipset, 1x PCIe 3.0 x16 / 1x PCIe 2.0 x4 / 2x PCIe 2.0 x1 / 2x PCI, 1x M.2 (PCIe 3.0 x4) & 6x SATA 6G, 2x USB 3.1 / 6x USB 3.0 / 4x USB 2.0 Motherboards with the AM4 socket serve as the platform for the AMD Ryzen (Summit Ridge) quad-core, hexa-core and octa-core CPUs as well as "Bristol Ridge" and "Raven Ridge" desktop APUs from the A-series with integrated GPUs unlike the old Athlon X4 which came without an iGPU. The advanced AMX X370, B350 and A320 chipsets are aimed at the enthusiast, mainstream and entry-level segments coming with an abundance of modern I/O interfaces and connectors for hardware peripherals, while additional data links are provided by the GPU/APU.

AMD Logo The processor's integrated memory controller supports AM4 motherboards as well as fast and energy- efficient DDR4 RAM in dual-channel mode, as well as specialist ECC error-correcting memory depending on the motherboard. The advanced "Zen" microarchitecture in conjunction with the AM4 platform forms the perfect foundation for high-performance systems in a range of applications.

The Layout of the ATX-Format ASUS Prime B350-PLUS

The ASUS Prime B350-PLUS is a motherboard utilising the ATX format and comes with a lightning-fast 16x PCI-Express 3.0 slot. Furthermore a PCIe 2.0 x4 slot, a PCIe 2.0 x4 slot, and two classic PCI slots for additional expansion cards are available. The four RAM slots accept up to 64 GB DDR4 RAM at up to 2666 MHz. The range of internal connectors includes, among other things, one USB 3.0 header and two USB 2.0 headers for a total of two and four ports respectively

Special Features at a Glance:

  • 1x PCIe 3.0 x16 for high-end GPUs / 1x PCI 2.0 x4 / 2x PCIe 2.0 x1 / 2x PCI
  • 2x USB 3.1 / 6x USB 3.0 / 4x USB 2.0 / 1x M.2 PCIe 3.0 x4 / 6x SATA 6G
  • 3x PWM fan ports (4-pin)
  • DDR4-RAM up to 2666 MHz
  • Modern UEFI-BIOS including temperature monitoring

Data storage devices such as SSDs and hard drives are managed via six SATA 6G connectors (incl. RAID support) as well as a horizontal M.2 slot which is connected via four PCI-Express 3.0 lanes and is capable of reaching speeds up to 32 Gbit/s. M.2-SSDs measuring from 42 mm to 110 mm in length can be used and furthermore the cutting-edge NVM-Express protocol to take advantage of the parallel processing utilised by modern PCIe SSDs.

A further highlight of the ASUS Prime B350-PLUS is to be found on the reverse of the motherboards, specifically the fact that the motherboard includes two USB 3.1 ports. USB 3.1 or USB 3.1 Gen 2 reach speeds of up to 10 Gbit/s per Port.

Last but not least the motherboard provides connectivity for three 4-pin PWM fans. The rear of the motherboard offers compatibility with additional devices and components over USB 3.0 and 2.0, Gigabit LAN, universal PS/2 or three audio jacks for connecting 7.1 sound to the ASUS Prime B350-PLUS. Furthermore display output options offered by the integrated APU-GPU (optional) include three monitor outputs: HDMI, VGA and DVI-D.

Attention: The actual I/O configuration may vary depending on the motherboard. This table only reproduces the basic interface layout. Additional ports may also be possible by means of alternative controllers.

Compatibility Note for CPU Coolers Utilising AMD Socket AM4:

Due to the revision in mounting hole distances for the new AM4 socket, CPU coolers with rear mounts will - compared with preceding sockets e.g. AM2(+), AM3(+) or FM2(+) - require AM4-compatible mounting brackets. Please ensure compatibility prior to purchasing. CPU coolers that are attached directly to the retention bracket of the motherboard retain compatibility.

can't complain

I can't complain. If you buy this motherboard. Do a bios update straight out of the bat. you can do it without installing is. it says it will only take a 32gig m.2 drive. I have installed a Samsung 970 evo 250gig m.2 drive without any problems. the only con here is it does not come with a m.2 standoff or securing nut and screw. there is some one on Amazon selling them for £ 16. I ended up making my own

Great Value Motherboard

I got this board on launch day not from OCUK but as you know motherboard on launch day were and still are like hens teeth.

So any way after having a solid 2 weeks with the board I can say it is a solid buy, it overclocks your CPU as far as you CPU will allow, my 1700x is 3.9ish. And it will run 3000Mhz ram at 2933Mhz when set to the correct timings. Concidering all the issues some folks have had I concider myself lucky I have had no such issues.

I would say if your looking for lot's of overclocking and raw performance then look at the higher end boards, but if you are after just a solid and fast system this B350 board from Asus ain't half bad.

AMD is back in a big way, and things should only improve.
