OPEN BOX - ASUS Pro A520M-C II/CSM AMD AM4 (3rd Gen Ryzen™) microATX Commercial Motherboard

Great for any application that requires a standardized footprint for quantity production. The manufacturer has committed to keeping this line of motherboards stable for a minimum of twelve months, with all updates conforming to the same general layout so products based on it will not require frequent hardware modifications.

Me gusto mucho que tenga displayport para aprovechar los amd APUs.

great little board, works perfectly . build pc booted no problem. will buy another one

My 1st venture into AMD land and it was a complete disaster. I had been saving and returning just to get a good processor and that i did (Ryzen 5 5600), but i failed miserably with the motherboard. I should have known when i opened the box and there were 0, that's ZERO motherboard screws and Zero Sata Cables. I thought maybe because AMD is a bit more advanced that was normal, but i quick look on YouTube and my fears were reality. I did have brand new extras so i used those. I can see why they don't give out screws, there were so many screw holes to connect the motherboard, so i guess that's a way of saving some money. So before i start to ramble on (to late). Ill get down to the fact that i called the 24 hour customer service to get some help, but must have been the 25th hour because they were closed. Oh, for the reason i called? The Motherboard ( ASUS Pro A520M-C II/CSM ) had No Display! Power was on, fans working, so i gave it some time. Then i did the reset on the CMOS, then clear the Battery and wait for it...then jump start the CMOS pins? Seriously. Stick a screwdriver in between the pins and that should almost definitely work...Well, it did not. After hours and hours of trying everything on the ASUS site and every weird idea on YouTube, I called Amazon, they told me to do the ever so often return. So i get to wait a few weeks for My $200 End of Rant

I opted for this board instead of a B450 that I have, because I wanted .my 3 monitors using digital output. This board has four outputs: DVI, HDMI, DisplayPort... and VGA. Unfortunately, when reading the manual, it states that the DisplayPort and DVI port don't work together. It's one or the other. Connect both, and the DVI takes over. Yes, I tested. Unfortunate. That information doesn't seem to be present on this ad. On ASUS' web site, it is under the pane with the detailed specs, a little off the beaten path. As it works fine otherwise, I decided to keep it. Everything else is in order... a simple, but study board, with all kinds of headers for old a new peripherals. It's clearly targeted at the corporate market. Pairs well with a Ryzen G-series.. It also support XMP, which came in handy, as I am using 3600Mhz RAM - also pairs well with a Ryzen G series. Remember to update your BIOS: the one that came with it wasn't very stable after boosting the RAM. A bios updated fixed that.
