Review: Top notch Am4 Board - This is a very nice am4 board, has 2 m2 drives and a spot for the wifi card. Plenty of sata connects,fan connects, (2) 3 and 4 pin rgb connections . Has alot and it looks great 5800x booted no problems out of the box.
Review: Love it! - Gosh I love this already. My husband got it for me to do a upgrade on my pc. I loooooove the white and rgb. Just looks awesome with the rest of my rgb setup. As for specs. If your here you most likely already know what your looking for in a motherboard. Annnnd I’m not the one who knows all the amazing specs with this. The husband is the one who did all that homework. I am enjoying the spoils of his hard work. And can confirm it’s a solid upgrade from my old system. 🥰

Works as it should. Was skeptical about ASRock.. but everything looks amazing and works perfectly. The shield near the motherboards USB is a bit flimsy.. other than that this is a fantastic motherboard.
