Buying for a desktop build gets confusing when motherboards and a standalone memory module are treated as interchangeable choices. Start by deciding whether you need a board for a planned platform or one memory stick, then narrow the board choice by its named processor support, connectivity, condition, and included accessories.
Quick take
The three motherboards serve different build directions, while the SK hynix Lenovo module is a separate desktop-memory purchase. The listed-price range spans $110, but price alone does not settle the choice: the MSI is the new-board route, the AORUS emphasizes a white-themed AM5 configuration, and the ASUS combines an AM5 board with a detailed accessory and port list. The memory module is for shoppers who specifically want a single-stick purchase.

Decision matrix
- Building around the listed Ryzen 3000, 4000G, 5000, or 5000 G-Series processor groups: put the MSI MAG B550 Tomahawk MAX WiFi on the shortlist.
- Planning a white-themed AMD Socket AM5 desktop: the AORUS X870E PRO ICE is the directly described match.
- Wanting a board package that expressly includes an I/O shield, Wi-Fi antenna, SATA cable, and M.2 hardware: look to the ASUS ROG STRIX B650-A GAMING WIFI.
- Shopping for memory rather than a motherboard: the SK hynix Lenovo HMCG78AGBUA081N is the dedicated module choice.
Product notes
MSI MAG B550 Tomahawk MAX WiFi Gaming Motherboard AM4 DDR4 ATX
Choose the MSI MAG B550 Tomahawk MAX WiFi Gaming Motherboard AM4 DDR4 ATX for a build planned around the Ryzen processor groups named in its description: 3000, 4000G, 5000, and 5000 G-Series. It also calls out PCIe 4.0, a Gen 4 x4 M.2 connection, 2.5G LAN, and Wi-Fi 6E, creating a specific mix of listed connectivity and expansion details. The constraint is fundamental rather than cosmetic: its AM4 and DDR4 wording directs this board toward that platform route. It is also the only motherboard here listed in new condition.
AORUS X870E PRO ICE AM5 ATX DDR5 PCIE WIFI 7 AMD EXPO Gaming Motherboard
Use the AORUS X870E PRO ICE AM5 ATX DDR5 PCIE WIFI 7 AMD EXPO Gaming Motherboard when an AMD Socket AM5 build calls for Wi-Fi 7 and AMD EXPO, both named in the title. Its white-themed presentation is paired with four DIMM slots and PCIe 5.0 storage options in the description. That gives the board a defined configuration for a themed desktop plan without relying on broad performance assumptions. A clear limitation is condition: this is an open-box board, making condition a meaningful distinction among the motherboard choices.
Factory Refurbished) ASUS ROG STRIX B650-A GAMING WIFI AMD AM5 ATX Motherboard
Select the Factory Refurbished) ASUS ROG STRIX B650-A GAMING WIFI AMD AM5 ATX Motherboard where the expressly included SATA cable, I/O shield, M.2 screws, M.2 standoff, and Wi-Fi antenna suit the build plan. Its expansion list names M.2, PCI Express x1, and PCI Express 4.0 x16, while the port list includes DisplayPort, HDMI, USB-C, and optical S/PDIF Out. Those named connections make it a focused fit for a port-conscious configuration. The trade-off is its Certified - Refurbished condition and service-white-box repacking.
SK hynix Lenovo 16GB PC5-5600B UDIMM DDR5 Desktop Memory RAM HMCG78AGBUA081N
SK hynix Lenovo 16GB PC5-5600B UDIMM DDR5 Desktop Memory RAM HMCG78AGBUA081N is a desktop-memory module rather than a motherboard, identified as DDR5 UDIMM with model HMCG78AGBUA081N. The description is direct about quantity: the purchase is for one stick. Choose it when a single-module purchase is your aim and PC5-5600B is the specification you are matching. Its limitation is equally direct: the item is open box, and the one-stick offer does not describe a multi-module bundle.
Final recommendations by use case
- For a new motherboard paired with the named Ryzen processor groups: choose the MSI MAG B550 Tomahawk MAX WiFi.
- For a white-themed AM5 build with Wi-Fi 7 and AMD EXPO in the title: choose the AORUS X870E PRO ICE.
- For an AM5 board where USB-C, optical S/PDIF Out, and DisplayPort are part of the listed port set: choose the ASUS ROG STRIX B650-A GAMING WIFI.
- For a desktop-memory purchase of one stick: choose the SK hynix Lenovo PC5-5600B UDIMM module.
