    Pros: A nice M-ATX board. Build a new system with a Ryzen 5 2400G APU, 16 GB ram. The board has everything I need, including an HDMI port to use with the APU. Supports Ryzen 3000 series CPUs out of the box. I like the black/gray color scheme, with a few orange light accents built in (these can be turned off in BIOS). Asus BIOS is very intuitive. Overall Review: Recommended

    Pros: Great for a budget build with a ryzen 5 2600. Easy bios navigation. Cons: None. Overall Review: Works as should. Asus is one of my go-to brands for motherboards. Decent price for a budget build I am making for a coworker.

    Pros: I always buy ASUS boards for my builds. I’ve used other manufacturers in the past and ASUS has always been the most reliable in my experience. Cons: None so far. Overall Review: Easy setup, works great, very stable system now compared to the Gigabyte board I had. Newegg is always great making returns easy. MATX makes install easier since it’s a tad smaller than your normal ATX board. I’d recommment a MATX form factor unless you need the added slots an ATX provides.

    Pros: The manual and online have all you need. Take it slow, search when you hick-up. I could have missed it, but some discussion on the cable routes might help the Newbie. I put in a top fan and front fan, should aid the back fan that is already installed. Cons: A bigger when a link is clicked. picture of the Motherboard online Overall Review: Yes to others for sure. I started out all ready to get another board, but this one was near enough and 1/2 the price.

    Pros: All the proprietary stuff plugged right in, all works. Ryzen 5 3600x processor. Cons: No cons, budget board to breathe life back into an old system. Overall Review: Yup good board, but economy model.

    Pros: It worked with Ryzen 5 5600G out of the box! OC my 3200 ram kit to 3600 with zero issues. I haven’t tried any serious OC but running smoothly so far. Very snappy with the CX2 512MB SSD but still waiting for my NVMe drive to see full potential! Cons: If you like RGB, make sure you have a splitter or daisy chained fans for your case! Only one M.2 NVMe slot so I would suggest a minimum 512GB to run your favorite games/programs but plenty of SATA connections to add SSDs or mechanical…
