First time building a PC everything went very well. Only thing that is strange is the lights dont turn off when the PC is turned off. So that is something to consider. I just flip my power supply switch off after I turn everything else off. So not too big a deal.

I paired it with a ryzen 5 5500 and rtx 3060 ti and it slays, incredibly fast with Kingston fury m.2 The motherboard rgb could be better, the brightness settings don't dim the lights enough. So I turned them off to show case the beautiful silver board and have to rgb fans up top down casting light on the board. Beautiful. Pop air mini case. ... show more

    • Good board
Nice build quality and features, but has a few design-related issues and had a couple software issues at launch (since fixed). The LAN would intermittently disable itself and had to have the device cycled through Windows to get it working again, which was fixed after a couple months through a BIOS update. More recently I discovered that the second M.2 slot for whatever reason causes electrical interference when in use to the front audio header, causing an annoying whine to speakers or headsets connected to it if your hearing is fine enough to catch it. From an aesthetic point of view it looks great, but the rear IO shield logo is partially obstructed by a normal-size rear exhaust fan. If you really want it displayed, make sure you have a slim fan back there or forgo one entirely. The chipset/M.2 cover will also be obscured by just about any graphics card. Its RGB control works fine. The logo and cover RGB don't power off with the system, only with the power switch flipped. Though I had my issues with it as an early adopter, I now recommend this if you're looking towards getting some of the X570's features but saving a bit of money. ... show more

    • Plug and play
Got this to pair with a new r7 5700x3d and it worked after installation without any bios updates. Easy to set up and one of the best value for am4 builds. Asrock has always been solid for me.

    • Good board for those who are in-experienced, and experienced alike.
Excellent board, POSTs pretty quickly, bios is fairly simple for those experienced in using computers.

    • So far so good
Works great out of the box, using 5800x3d no problems. The only thing i dont like about it is the RGB leds on the MB are too strong and wont turn off when the PC is off / hibernate or sleed mode. You have to completely turn it off from the Bios / via Asrock sofrware
