The NVMe drives in RAID configurations have the ability to take advantage of extra bandwidth with sequential read\/write speeds. The PSU 8+4 pin connectors can pass more current (at least 12V) than hollow-pin connectors. The compatible USB 3.2 Gen2 Type-A has flexible connectivity and blazing data transfer rate up to 10Gbps. The multiple temperature sensors, AIO pump, four-pin DC fan, and smart protection are the comprehensive cooler options. Lastly, the BIOS has a great GUI interface.\u00a0\r\n\r\n\r\n\r\nDownsides: Like ASUS Crosshair VIII Hero Wifi the chipset fan of Prime X570-P directly sits under the GPU. Also it has neither the access of wireless internet nor USB Type-C ports.\r\n\r\n\r\n\r\n\r\n\r\nFinal Thoughts\r\n\r\n\r\n\r\nThe software and firmware controls of ASUS Prime enables you to make performance accessible to anyone. Also, You can personalize your build and tune your rig to perform the way you want.\u00a0\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\t\tView On Amazon\r\n\t\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\nMSI B450 Tomahawk Max\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\nB450 Tomahawk Max, another MSI creation that has beyond imagined features compared to its budget-entry level price. The heavy-plated extended heatsink with a military-style doesn\u2019t only have looks but also is designed for maximum cooling. Also, USB 3.2 Gen2 connector, RGB LED lighting, PCIe slots with STEEL ARMOR are the core features of Tomahawk Max. Moreover, the audio boost helps optimize gaming audio using the best components.\u00a0\r\n\r\n\r\n\r\nKey Features: The Flash BIOS button is capable of flashing any BIOS even without installing a CPU, memory, or graphics card. Also, you have better than expected storage capability. The six SATA ports are capable of supporting RAID arrays 0,1, and 10. Furthermore, the DDR4-3466 has a maximum capacity of more than 64GB across the four memory slots. Along with having five PCIe slots, it has upgraded power delivery heatsinks that are extended over towards the rear IO panel. The overclocking performance is above average whereas the power consumption of B450 is great. It can do well at a maximum load even with lower maximum power.\u00a0\r\n\r\n\r\n\r\nDownsides: You can\u2019t control your RGB headers as you wish. Also, though the M.2 slot doesn\u2019t share bandwidth with other PCIe slots, you can\u2019t make it crowded with a drive. Because it will disable the two of six SATA ports and that is absolutely not admirable.\r\n\r\n\r\n\r\n\r\n\r\nFinal Thoughts\r\n\r\n\r\n\r\nAs an MSI member, B450 Tomahawk is DIY friendly with a black and grey design along with linear RGB. It will look perfect on any decent yet stylish build. Though it lacks many of the premium features, it is absolutely a good choice, to begin with.\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\t\tView On Amazon\r\n\t\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\nASRock B450M Steel Legend\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\nASRock B450 is a wallet-friendly yet aesthetically admiring Ryzen 9 3900x motherboard. It has this rock-solid durability as well as stainless steel design. The M.2 slot that has connectivity with SSDs or hard drives, four SATA 3 ports, two USB 3.2 Gen2 (Type-A and C) on the rear IO panel, and six USB 3.2 Gen1 are the basic features of B450 Steel legend. These USB ports are capable of delivering up to 10Gbps data transfer rate.\r\n\r\n\r\n\r\nKey Features:\u00a0 B450 Steel Legend provides a strong array of materials and components to ensure a tuned performance. One of the dual M.2 slots delivers more than PCIe Gen3 x4 32Gb\/s transfer speed while the other supports 6Gb\/s SATA 3 mode. The RGB\/LED is much expanded and they look pretty nice with a good color effect.\u00a0 You can also work with the software easily without encountering any problem. The IO connections, fan headers, and CPU socket clearance are easy to deal with.\u00a0\r\n\r\n\r\n\r\nDownsides:\u00a0 ASRock B450 has only six power phases which gives an average overclocking performance. The connectivity system is a bit weak with no Wi-Fi and frontal USB 3.1 Gen2.\r\n\r\n\r\n\r\n\r\n\r\nFinal Thoughts\r\n\r\n\r\n\r\nThere aren\u2019t any significant differences in B450 Steel Legend with other motherboards except the deduction of power phases. The quality of the build is pretty good and even if it doesn\u2019t have any other special features it has the ability to be in our recommendations.\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\t\tView On Amazon\r\n\t\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\nASRock X570M Pro4\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\nASRock X570 Pro4 is the best one in the Micro ATX aspect as it delivers a rare Micro-ATX board. And, it is the only mATX you will find on the market which is why, if you need an mATX mobo this is the only option. X570M holds 10 power phases, 3 PCIe slots and 1 M.2 for WI-Fi, 8 SATA III, and dual M.2 slots as its features.\u00a0 Micro-ATX is always left out. The biggest proof is this mobo as there really aren\u2019t any other Micro-ATX compared to ATX\/E-ATX\/Mini ITX. And it is a matter of shame because mATX can support more components and devices and also has better power delivery than Mini ITX.\r\n\r\n\r\n\r\nKey Features:\u00a0 The pair of 2 USB 3.2 Gen2 (Type-A and C) and 8 USB 3.2 Gen1 (2 front and 6 rear) delivers up to 10Gbps transfer rate. This motherboard also supports DDR4 ECC that produces stable performance and solid durability for your high-end computing system. It has five Fan headers along with a plug for chipset fan. You can use both LAN port and Wi-Fi 802.11ax by M.2 slot for connectivity. The dual hyper M.2 slot for SSDs are capable of performing twice the speed compared to its previous generation as well as giving a fast lighting data transfer experience.\r\n\r\n\r\n\r\nDownsides: The chipset fan is always hot and it runs at max all of the time. Many of the AGESA versions had to fix, unfix, and again boost them after fixing were the most common issues.\r\n\r\n\r\n\r\n\r\n\r\nFinal Thoughts\r\n\r\n\r\n\r\nThere is no need to choose between Micro-ATXs as it is the only option. We would say, it has some issues that need to be updated. Yet, we have no say to this one as the best.\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\t\tView On Amazon\r\n\t\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\nGigabyte X570-I\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\nGigabyte X570-I is the last best motherboard and Mini-ITX we have listed.

X570-I includes solid 8 phase digital VRMs, two ports of USB 3.1 Gen2 (Type-C and A) on the rear IO panel, Wi-Fi 6\/802.11ax, and LAN port options. Other features are RGB LEDs, steel armor on PCIe slots and DIMM, ESD guards, etc.\u00a0\r\n\r\n\r\n\r\nKey Features:\u00a0 X570-I\u2019s Wi-Fi is capable of supporting both Ryzen 2nd and 3rd generation processors which also includes four SATA ports and two PCIe 4.0 x4 M.2 slots. The pair of DIMM supports 64GB of DDR4 RAM and the overclocking speed is up to a fast DDR4 4400MHz. The direct 8 phases Digital VRM solution delivers decent power and the multiple temperature sensors do a great job while the heatsink and cooling fan system reduce the warmness. The fan headers have the feature \u201cFan STOP\u201d just like Gigabyte X570 AORUS Elite.\r\n\r\n\r\n\r\nDownsides:\u00a0 Though the heatsinks and fan headers reduce the temperature with its utmost quality, two fan headers are still not enough. Also, the 1st M.2 slot for the board chipset is right above the heatsink.\r\n\r\n\r\n\r\n\r\n\r\nFinal Thoughts\r\n\r\n\r\n\r\nMini ITX boards are capable of handling anything from an HTPC to a full gaming rig. Gigabyte X570-I is undoubtedly a good choice as a Mini ITX board as there aren\u2019t many boards with the highest of six USB ports, though it is a small factor.\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\t\tView On Amazon\r\n\t\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\nClosing Thought\r\n\r\n\r\n\r\nFinally, we\u2019re at the end of the discussion and these are the best motherboards for Ryzen 9 3900x in our eyes. But it doesn\u2019t mean we will choose randomly. Our pick is Gigabyte X570 AORUS Xtreme, the completely passive board. This high-end option should be a good pick.
