    After 8 years, I'm finally upgrading from my AMD FX-8320/ASRock 990FX Professional Fatal1ty.The specs right now:AMD Ryzen 5 3600Team T-Force Delta DDR4 3200 RGBSabrent 512GB Rocket NVMe PCIe M.2Generic Radeon 7450Corsair RMx White Series™ RM750x 750 Watt 80 PLUS® GolddarkFlash DLM21 WhiteI love this motherboard. Out of the box it supports the Ryzen 5 3600, shipping with bios 2.90. Setup was extremely easy using the generic Radeon. It comes with 2 M.2 slots, however, the slot nearest the SATA slots shares the SATA 3 port, so you can either use the m.2 or you can us an SSD in SATA port 3, not both. Using that m.2 does not conflict with SATA ports 0, 1, 2, etc. Only SATA 3.I love RGB so this board made sense for my build. Not only does the South Bridge and back panel cover have addressable RGB, but there is both a 5v addressable (3pin) and 12v RGB (4pin) headers...ASRocj's own PolyChrome RGB software can control anything connected to the RGB headers and can control the RGB of specific memory, in my case the T-Force Delta Ram. Additionally, Polychrome can control RGB on video cards, keyboards, mice, Headsets, etc. My only issue is that PolyChrome doesn't seem to sync the ram and motherboard RGB.Aesthetically, the motherboard has a digital camo look, featuring white. gray, and black, that carries over to the backplate. This color scheme fits with the White/Black build.Overall, I am extremely happy with this motherboard. Definitely recommend.Update 2/4/21.... I've since upgraded to 32gb of ram and first had a GTX 1080 and now on an RTX 2070. I've also added ID-Cooling Zoomflow 240x AIO, and darkFlash's DR12 pro 120mm argb fans and lastly, a set of white cable extensions. The board is rock solid.
