Building or upgrading a PC gets complicated when the choices do not serve the same kind of system. In this CPUs, motherboards & memory comparison, the key decision is not simply which item costs less: it is whether your plan calls for an AM4 board, an AM5 board, or registered ECC memory for a compatible rack server. Choose the platform and memory type first, then let the included connections, expansion choices, and condition guide the final call.
Quick take
- Pick the MSI MAG B550 Tomahawk MAX WiFi for an AMD Ryzen 3000, 4000G, or 5000-series desktop build that uses DDR4.
- The AORUS X870E PRO ICE suits an AM5 build centered on a white-themed ATX look and DDR5.
- Choose the ASUS ROG STRIX B650-A GAMING WIFI when an AM5 DDR5 board with the stated accessory bundle fits your build plan.
- The HP DL360 DL380 G9 G10 memory kit is for the named HP rack-server family, not a consumer desktop.
Listed price comparison
| Item | Listed price | Price position |
|---|---|---|
| MSI MAG B550 Tomahawk MAX WiFi Gaming Motherboard | USD 167.99 | |
| AORUS X870E PRO ICE AM5 ATX DDR5 Gaming Motherboard | USD 199.99 | |
| ASUS ROG STRIX B650-A GAMING WIFI AM5 ATX Motherboard | USD 124.99 | |
| HP DL360 DL380 G9 G10 128GB DDR4 ECC Memory Upgrade Kit | USD 499.95 |
The range runs from the refurbished ASUS board to the eight-module HP server-memory kit. That spread reflects four very different purchase types, so it should not be treated as a like-for-like motherboard contest.
Decision matrix
- Choose MSI MAG B550 Tomahawk MAX WiFi for a desktop build where PCIe 4.0 and the listed Lightning Gen 4 x4 M.2 arrangement are relevant.
- Choose AORUS X870E PRO ICE for a silver-and-white ATX build; it also lists M.2 expansion and HDMI plus Ethernet ports.
- Choose ASUS ROG STRIX B650-A GAMING WIFI if the included SATA cable, I/O shield, M.2 screws, standoff, and Wi-Fi antenna are useful for your build.
- Choose HP DL360 DL380 G9 G10 memory kit when you need eight 16GB registered ECC modules totaling 128GB for the stated HP server systems.
Product notes
MSI MAG B550 Tomahawk MAX WiFi Gaming Motherboard AM4 DDR4 ATX
This MSI board is the direct fit for a desktop plan built around the explicitly supported AMD Ryzen 3000, 4000G, 5000 G-Series, or 5000 Series processors. It is listed as new and pairs its AM4 platform with DDR4 memory support, making its intended direction clear for an existing or planned DDR4 Ryzen build. The description also names a 2.5G LAN connection, Wi-Fi 6E, and an extended heatsink design. Its practical limitation is platform specificity: it is an AM4 DDR4 motherboard, so it is not the choice for an AM5 or DDR5-oriented build.
AORUS X870E PRO ICE AM5 ATX DDR5 PCIE WIFI 7 AMD EXPO Gaming Motherboard
The AORUS X870E PRO ICE makes sense for an AMD Socket AM5 system that calls for DDR5 across four DIMM slots. AMD EXPO compatibility is named, and the board's white-themed, silver-and-white styling gives builders with a coordinated visual plan a concrete reason to choose it. It is listed in open-box condition and has on-board audio as well as M.2 expansion. One constraint deserves attention in the build layout: using certain secondary PCIe 5.0 M.2 slots may scale the primary x16 graphics slot to x8 mode, according to the product description.
ASUS ROG STRIX B650-A GAMING WIFI AMD AM5 ATX Motherboard
For an AM5 desktop using DDR5, the ASUS ROG STRIX B650-A GAMING WIFI is the lower-priced motherboard in this group and supports AMD Ryzen 7000 Series desktop processors. Its expansion listing includes M.2, PCI Express x1, and PCI Express 4.0 x16, while the port list includes DisplayPort, HDMI, Ethernet, USB-C, and optical S/PDIF out. The board is certified refurbished rather than new, and it is repacked in an ASUS service white box. Its stated bundle is focused: SATA cable, I/O shield, M.2 hardware, and Wi-Fi antenna are included.
HP DL360 DL380 G9 G10 8x16GB (128GB) PC4-2133P DDR4 ECC Memory Upgrade Kit
This HP kit answers a very different need: adding memory to the named DL360, DL380, or BL460c G9/G10 rack-server environment. Eight 16GB modules provide 128GB total, and the modules are registered ECC RDIMMs with a listed PC4-17000 (DDR4-2133) bus speed. It is a sensible route when that server-focused capacity and module format are central to the project. The limitation is explicit and important: these modules will not work in consumer desktops, and they cannot be added where LRDIMM sticks are already installed. The kit is listed as used.
Final recommendation by use case
For a DDR4 Ryzen desktop using the processor generations named above, select the MSI AM4 board. Choose the AORUS for an AM5 DDR5 build where its white-themed ATX presentation and AMD EXPO support matter. The ASUS is the straightforward AM5 route for a Ryzen 7000 desktop when its certified-refurbished condition and included setup hardware suit your project. Reserve the HP kit for compatible DL360, DL380, or BL460c G9/G10 server deployments requiring registered ECC RDIMMs.
