Review: good product - good product
Review: A really Gorgeous b550 motherboard - An amazing and beautiful looking b550 motherboard. I think it's one of the best looking motherboard out there with minimalist design and no rgb, and the white colour really makes it stand out from other b550 motherboards. It has all the features that you would need like 12+2 phase vram for extreme overclocking even with a 5900x. It also got 2 m.2 slots for nvme ssd and lots of fans connectors plus an argb header with another 4 pin rgb header. It also has 4 troubleshooting leds and a thunderbolt header for those looking for one. Overall I'm really happy I got this one instead of the strix b550 f gaming
