Choosing CPUs, motherboards & memory is less about picking a feature-packed name and more about avoiding a platform mismatch. Here, the key split is between an Intel LGA 1151 board, AMD AM4 and AM5 boards, and a separate DDR5 memory choice. Settle the processor and memory direction first; use the listed price to refine the shortlist.
Quick take
The MSI Z390-A PRO is the focused Intel route, while the MSI MAG B550 Tomahawk MAX WiFi occupies the AMD AM4 lane. The AORUS X870E PRO ICE is the AMD AM5 option, with a white-and-silver ATX design. G.SKILL Ripjaws S5 is different from the other three: it is desktop memory, not a motherboard. Listed prices span a broad range, making platform fit the more useful first filter.
Listed-price comparison
| Choice | Listed price | Price position |
|---|---|---|
| MSI Z390-A PRO LGA 1151 motherboard | USD 172.21 | |
| AORUS X870E PRO ICE AM5 motherboard | USD 199.99 | |
| MSI MAG B550 Tomahawk MAX WiFi motherboard | USD 167.99 | |
| G.SKILL Ripjaws S5 DDR5 desktop memory | USD 379.00 |
Decision matrix
- For an 8th- or 9th-generation Intel build: the MSI Z390-A PRO explicitly names LGA 1151 and those Intel generations.
- For an AMD AM5 motherboard direction: the AORUS X870E PRO ICE is labeled AM5, ATX, DDR5, and AMD EXPO.
- For an AMD AM4 motherboard direction: the MSI MAG B550 Tomahawk MAX WiFi is labeled AM4 and DDR4.
- For the memory portion of a desktop build: the G.SKILL Ripjaws S5 is the standalone DDR5 memory selection rather than a board.
Product notes
NEW MSI Z390-A PRO Motherboard LGA 1151 for 9th/8th Intel ATX M.2 USB 3.1 DDR4
The MSI Z390-A PRO fits an Intel-focused component plan where the processor is already an 8th- or 9th-generation model. Its M.2 and USB 3.1 wording supplies a concrete connection-and-expansion starting point, and it is an ATX board for a desktop build. The key constraint is equally clear: this is an LGA 1151 DDR4 choice, not a catch-all answer for the other platform directions represented here. It makes the most sense when the Intel generation and DDR4 language are already established in the rest of the build, rather than when starting from an AMD processor plan.
AORUS X870E PRO ICE AM5 ATX DDR5 PCIE WIFI 7 AMD EXPO Gaming Motherboard
AORUS X870E PRO ICE suits an AM5 build aiming for a white-and-silver ATX appearance while placing WiFi 7, PCIe 5.0 storage options, and on-board audio among its stated features. Four DIMM slots and AMD EXPO are also described, giving shoppers several specific design details beyond the socket label. The important limitation is condition: this board is listed as open box. That makes it a logical fit for someone pursuing the named AM5 route and those connectivity and visual cues, provided the open-box designation aligns with how they want to shop.
MSI MAG B550 Tomahawk MAX WiFi Gaming Motherboard AM4 DDR4 ATX
The MSI MAG B550 Tomahawk MAX WiFi fits a motherboard-led AMD build that calls for its named AMD B550 chipset. Its description highlights PCIe 4.0, a Gen 4 x4 M.2 connection with M.2 Shield Frozr, 2.5G LAN, and WiFi 6E, creating a distinct network-and-storage feature set to weigh. Its limitation is platform focus: support is stated for Ryzen 5000, 5000G, 4000G, and 3000 series processors alongside DDR4 memory. Choose this route when those stated processor families are already part of the planned build.
G.SKILL Ripjaws S5 32GB 1x32GB DDR5 6000 CL32 XMP 3.0 Intel Desktop Memory
G.SKILL Ripjaws S5 is the dedicated memory selection, aimed at Intel desktop memory with DDR5-6000, CL32, and XMP 3.0 cited in its title. Its listed 32 GB capacity per module and low-profile 33 mm heat spreader give a concrete capacity and physical-profile frame. The central limitation is role: it is memory rather than a motherboard, so it addresses the RAM portion of a desktop plan without selecting a socket or board. The described UDIMM, non-ECC configuration further defines the kind of desktop-memory setup it is intended to serve.
Final recommendations by use case
- Intel LGA 1151 build: Pick the MSI Z390-A PRO when its named 8th/9th-generation Intel path matches your processor; it is listed at USD 172.21.
- AMD AM5 build: Choose AORUS X870E PRO ICE for the AM5 motherboard route at USD 199.99, with the open-box condition in mind.
- AMD AM4 build: Select MSI MAG B550 Tomahawk MAX WiFi when the stated Ryzen family support suits the build; its listed price is USD 167.99.
- DDR5 desktop-memory selection: Go with G.SKILL Ripjaws S5 when the DDR5-6000 CL32 XMP 3.0 specification is the memory target; it is listed at USD 379.00.
