What customers say about "Key Specs"
ASUS PRIME B350-PLUS
  • I have added an EVGA 750 power supply, a 1500x processor, 16 gigs of Corsair vengeance 3200/25600 ram, a Rosewill dual antenna Wi-Fi card, an led lighting card, two Blu-Ray optical drives and an XFX Radeon RX 460 2 gig video card. Works perfect!
  • I find this board very easy to navigate, understand, it feels fairly sturdy and all my parts play very well together!
  • This is a very good motherboard as far as value goes. I have it paired with a r5 1600 and run it at 3.7gh with under 1.4 volts and everything run good.
  • Good Mobo. Works well with Corsair Dominator Platinum 32GB (2x16) 3000Mhz memory. I am so pleased!
  • I have the Ryzen cpu over clocked using its included cooler with no issues. I believe it’s set a 36.5 or 37.5 multiplier.
ASUS PRIME B450-PLUS AM4/B450/DDR4/S-ATA 600/ATX Socket Motherboard - Black
  • Much quieter with newer AMD processor, board functions well, no dropouts on devices connected to USB 3 connections.
  • Coupled with a ryzen 3, Fantastic performance!
  • Good board, easy to install and compatible with most processors and ram meaning no need to download extras for compatibility purposes.
  • Compatibility of this board is good, supports a lot of CPU.
  • Minor issue was it is slightly smaller (width ways) than a regular ATX motherboard and so only requires 6 motherboard stand offs.

What customers say about "Memory"
ASUS PRIME B350-PLUS
  • Memory wasn’t clocked right initially but that was remedied in the bios to get correct timings.
  • Memory speed is awesome, highly recommended!
  • I like the memory speed, really fast, good purchase!
  • There is one significant issue and that is with my memory speed.
  • You have to update the bios files right away which makes the motherboard stable and more compatible with ddr4 memory kits.
ASUS PRIME B450-PLUS AM4/B450/DDR4/S-ATA 600/ATX Socket Motherboard - Black
  • Memory originally at 2133Mhz, but easily reached 3000Mhz through activation in the BIOS.
  • Got this with the ryzen 2600 and patriot viper 300mhz ddr4. Worked perfect out of the box.no update was required. Highly recommended.
  • Obviously good memory speed, without overclocking.
  • Good compatibility, good quality, memory speed a decent!
  • Memory speed should be a more faster for that price!

What customers say about "Connectivity"
ASUS PRIME B350-PLUS
  • I used a USB stick to update the BIOS (which is strongly recc.) and it worked flawlessly. No problems.
  • It looks wonderful, has a lot of USB ports. Nice!
  • Easily configurable. Widely compatible. I never thought I'd need so many USBs but I'm so happy I have them.
  • USB 3.0 card reader was not recognized so I had to plug it into a USB 2.0 slot where it booted up and installed with no issue.
  • The directions to install the header cables could have been clearer. The diagram looks like it’s starting at the left hand most side but in actuality your plugging these in more of the center arrangment of pins.
ASUS PRIME B450-PLUS AM4/B450/DDR4/S-ATA 600/ATX Socket Motherboard - Black
  • There is a bigger gap below the main PCIE slot, as most newer graphics cards are extra thick - this means the next PCI slot is not obscured - nifty!
  • This has the nextgen USB 3.1 ports (coloured green) for high speed devices - supposed to move from 5GB/s to 10!
  • There is a USB-C connector (which I needed), headers for front-mounted USB-3, and 4x PWM fan headers as well as a CPU/Waterpump header - perfect.
  • It looks decent, has a lot of ports as i needed. Recommended!
  • No installation support for Win7. It says 2 USB ports are usb2.0 , but don't work with Win7 installation disc at all. No chance to change anything in bios to make it working.

What customers say about "Features"
ASUS PRIME B350-PLUS
  • This is a great board, looks real nice, pretty darn easy to overclock, lots of useful bios settings, a very attractive UEFI bios, lots of nice features!
  • The AMI Bios update tool (Under Tools in the Advanced Setup) works great either using an Ethernet cable and pulling it from Online or by downloading the file and using a memory stick)
  • I've built two Ryzen systems one using a Ryzen 3 1300X and another using a Ryzen 5 1600 using the supplied CPU coolers which work well
  • Uses the ALC887-VD2 8-Channel High Definition Audio CODEC, but only one line-out on the back of the board.
  • I would like to see another fan header, but that's just nitpicking.
ASUS PRIME B450-PLUS AM4/B450/DDR4/S-ATA 600/ATX Socket Motherboard - Black
  • Packed with features - clear and simple BIOS.
  • Clean looking board with plenty of features, including an m.2 slot.
  • Has an orange light which doesn't fit the my white build but can easily be turned off in the bios.
  • BIOS was easy to use and control, even for a first time builder such as myself.
  • A very solid board with excellent features for the money. Highly recommended for mid range builds.
