Choosing cpus, motherboards & memory starts with a compatibility fork, not a simple price call. A board can share an ATX format with another model yet be built around a different CPU socket and memory generation. The meaningful routes here are AMD AM4 with DDR4, AMD AM5 with DDR5, and Intel LGA 1151 with DDR4. Set that route first, then use listed price, condition, networking, storage expansion, and the accessory bundle to settle the close call.
Quick take
The four boards are not interchangeable, so platform wording is the first filter. The listed-price range runs from $124.99 to $199.99, with the ASUS at the lower end and the AORUS at the upper end. Beyond price, the key distinctions are the AORUS white-themed AM5 layout, the ASUS accessory set and refurbished condition, the MSI B550 networking specifications, and the MSI Z390-A PRO's Intel focus.
Listed price comparison
| Motherboard | Listed price | Relative listed price |
|---|---|---|
| MSI MAG B550 Tomahawk MAX WiFi Gaming Motherboard AM4 DDR4 ATX | USD 167.99 | |
| AORUS X870E PRO ICE AM5 ATX DDR5 PCIE WIFI 7 AMD EXPO Gaming Motherboard | USD 199.99 | |
| ASUS ROG STRIX B650-A GAMING WIFI AMD AM5 ATX Motherboard | USD 124.99 | |
| MSI Z390-A PRO Motherboard LGA 1151 for 9th/8th Intel ATX M.2 USB 3.1 DDR4 | USD 172.21 |
Decision matrix
Use the requirement that is hardest to compromise on rather than trying to make every board serve the same build.
- White-themed AMD AM5 build with four DDR5 DIMM slots: choose the AORUS X870E PRO ICE.
- Named in-box SATA cable, I/O shield, M.2 screws, standoff, and Wi-Fi antenna: choose the ASUS ROG STRIX B650-A GAMING WIFI.
- 2.5G LAN and Wi-Fi 6E: choose the MSI MAG B550 Tomahawk MAX WiFi.
- DisplayPort and dual-channel memory support: choose the MSI Z390-A PRO.
Product notes
MSI MAG B550 Tomahawk MAX WiFi Gaming Motherboard AM4 DDR4 ATX
The MSI MAG B550 Tomahawk MAX WiFi is the natural route for a build focused on the Ryzen 5000, 5000 G-Series, 4000G-Series, or 3000 Series processor families supported by the board. It combines AM4 and DDR4 in an ATX format, while also naming PCIe 4.0, an M.2 Shield Frozr, 2.5G LAN, and Wi-Fi 6E. That is a concrete mix for shoppers who want those Ryzen families alongside wired and wireless networking options. Its boundary is equally clear: AM4 and DDR4 place it on a different platform path from the AM5 DDR5 boards in this comparison.
AORUS X870E PRO ICE AM5 ATX DDR5 PCIE WIFI 7 AMD EXPO Gaming Motherboard
The AORUS X870E PRO ICE suits an AMD Socket AM5 build using DDR5, especially where WiFi 7, AMD EXPO, and a white-themed ATX board are part of the brief. It supports Ryzen 9000, 8000, and 7000 series processors and has four DDR5 DIMM slots. An M.2 expansion slot and on-board audio are part of its configuration as well. The limitation to weigh is condition: this AORUS board is open box. Choose it for the specific AM5 DDR5, WiFi 7, and Ryzen-series combination rather than as an interchangeable answer for AM4 or Intel LGA 1151.
ASUS ROG STRIX B650-A GAMING WIFI AMD AM5 ATX Motherboard
The ASUS ROG STRIX B650-A GAMING WIFI puts AM5, ATX, and DDR5 SDRAM together with M.2, PCI Express x1, and PCI Express 4.0 x16 expansion slots. It is the $124.99 entry in the price table, making it the price-led route for a shopper whose build calls for those AM5 and expansion-slot details. The package includes a SATA cable, I/O shield, M.2 screws, M.2 standoff, and Wi-Fi antenna. The tradeoff is explicit: it is certified-refurbished and repacked in an ASUS service white box, with only those named accessories.
MSI Z390-A PRO Motherboard LGA 1151 for 9th/8th Intel ATX M.2 USB 3.1 DDR4
The MSI Z390-A PRO is the focused pick for an LGA 1151 ATX build using 9th- or 8th-generation Intel processors and DDR4. Its title calls out M.2 and USB 3.1, while its specifications identify a DisplayPort and dual-channel memory support. That makes its purpose easy to separate from the AMD boards: it follows the Intel LGA 1151 and DDR4 route. That same focus is the limitation. It is not the AM4 DDR4 configuration of the B550 board or either AM5 DDR5 configuration; select it when the 9th/8th Intel and LGA 1151 wording matches the rest of the build.
Final recommendation by use case
For a Ryzen 9000, 8000, or 7000 series build where four DDR5 DIMM slots matter, the AORUS X870E PRO ICE is the direct match. Choose the ASUS ROG STRIX B650-A GAMING WIFI for an AMD Ryzen 7000 Series desktop build that benefits from its Multi-GPU Support or Dual LAN. The MSI MAG B550 Tomahawk MAX WiFi is the targeted answer for the supported Ryzen 5000, 5000 G-Series, 4000G-Series, and 3000 Series families. For a 9th- or 8th-generation Intel build, the MSI Z390-A PRO is the board that explicitly names that processor generation and LGA 1151.
