NVIDIA is a leading graphics cards manufacturer globally, serving tech enthusiasts for years with well-researched and excellently built tech products. The GeForce RTX 3090 is a classy graphics chip packed with NVIDIA’s second-generation RTX Amper architecture along with a signature pack of advanced Ray Tracing and Tensor cores for high-quality graphics. It has 24GB of fastest GDDR6x memory operating on a 256-bit memory interface and a 1700MHz engine boost clock. You can utilize awesome-looking 4k 90+ fps quality in-game graphics and even up to 8k 60+ resolutions as well. But it’s only possible when you combine the card with one of the best motherboards for RTX 3090 since it directly impacts the performance.
A motherboard is like a backbone for a system carrying a majority of the computer elements and supervising the overall performance. No doubt, a mobo also affects the latencies, so the speeds of the elements are also decided by the board. When it contributes so much to the system’s efficiency, we can’t just put any motherboard into the rig. Considering the RTX 3090 in this post, we need to connect a high-end motherboard with the card since the card falls in the top-tier beast category. We can go for the 400-series and 500-series mother circuits, especially 500-ones, since these are more likely to match the performance capabilities.
1. ASUS ROG Strix X570-E Gaming
Starting reviewing the products with the ASUS ROG Strix X570-E Gaming, which is a well-built motherboard offering high-end performance via the latest X570 chipset. Undoubtedly, it’s totally valid to say it’s the best motherboard for RTX 3090. Since it’s built on a multi-layer PCB, you can expect effective signal transmission and a longer lifespan than other items. You can accommodate the latest Ryzen 5000 processors via AM4 socket along with 128Gb volatile memory split into four DDR4 DIMMs with 4600MHz memory speed. The board follows a black theme with eye-catching controllable RGB lighting to further beautify the overall look.
As far as connectivity matters, it has pretty much everything a gamer may need during the gameplay. It has plenty of USB connections, eight SATA 6Gb/s ports, PCIe 4.0 connections, and two M.2 slots for SSDs with Bluetooth 5.0, 2.5 Gbps LAN, and 2.4 Gb/s WiFi 6 for wireless communications. Most importantly, its 12+4 power design effectively feeds a smooth power input to all the connected elements. On top of that, this best gaming motherboard for RTX 3090 will help you target your opponents via the SupremeFX S12204 chip for clear-crystal audio.
- Excellent performance
- Bluetooth, Dual LAN, Wifi 6
- Multi-GPU support
- 12+4 power phases
- Only two M.2 slots
2. MSI MPG X570 GAMING PLUS
The MSI MPG X570 Gaming Plus is an excellent addition to the tech world with a long list of jaw-dropping features and specifications. It’s the best premium motherboard for RTX 3090 since you can enjoy the fastest X570 chipset but without spending too many bucks like most of the competitors. You can put over four DDR4 DIMMs with a 4400+ MHz memory speed based on its dual-channel memory architecture. When the board can provide you with so much, it needs an adequate power connector, and this requirement is fulfilled via an 8+4 pin CPU power connector.
There is pretty much everything packed with the card that you may need during any type of usage time. It has two PCIe x16 and three x1 slots, six SATA III 6Gb/s ports, two M.2 ports, and plenty of USB ports. The board has a Realtek 8111H Gigabit LAN Controller of Ethernet connection but not the Bluetooth and Wi-Fi support which is slightly lackluster. There are also six audio jacks with one HD Audio header to take the efficient audio quality from the audio codec ALC1220 chip.
- Convenient SATA and USB ports locations
- Heatsink for M.2 SSDs
- Adequate voltage for Ryzen 3K range
- No WIFI and Bluetooth
3. GIGABYTE B550M AORUS PRO
There are two most famous stocks in the 500-series motherboard, B500, and X500; out of the B500, the B550 is the most famous one. Most of the time, the B550 mobos offer less performance and features than the X570 but not this time. The Gigabyte B550M Aorus Pro is packed with quite the same speeds as the expensive mother circuits with X570 chipset and can power the latest 2nd and 3rd generation AMD Ryzen processors. It’s the best micro ITX motherboard for RTX 3090 since it’s packed with the same stuff as the larger boards, including excellent cooling, power distribution, and more.
It has all-type USB connections, two PCIe 4.0 ports, and two M.2 slots with 64GB/s of transfer speeds. Like the previous MSI MPG X570 Gaming Plus, it isn’t equipped with Wi-Fi and Bluetooth but has a Realtek GbE LAN chip for wireless communication. Moreover, I’m happy to see 10+3 power phases design and lower RDS (on) MOSFETs than the typical solutions. No doubt, thermal management becomes excellent when there are bigger heatsinks, Hybrid Fan headers, Smart Fan 4 technology, and one M.2 with a dedicated heatsink.
- Excellent performance
- Features-rich product
- Exclusive 8118 Gaming GbE LAN
- Effective cooling
- Only one M.2 has a heatsink
- No USB controllers
