Replacing a Dell desktop motherboard and planning an Intel DDR4 build are two very different jobs, even when every choice uses an Intel-compatible platform. The practical decision in CPUs, motherboards & memory is to start with the exact desktop model or processor generation you need to support, then choose between MicroATX and ATX labels where they are stated. The four boards span a $128.25 listed-price spread, so a model match can matter more than simply choosing the lowest figure.
Quick take
- For a Dell Precision 3650 Tower: the Dell Precision 3650 Tower Intel W580 Socket LGA1200 Motherboard NDYHG 0NDYHG is the model-specific route, with BIOS Unlocked and Computrace Unlocked stated for this used board.
- For a Dell XPS 8940: the Dell XPS 8940 Desktop Motherboard Intel 10th 11th Gen LGA1200 DDR4 K3CM7 427JK directly names that desktop and 10th- and 11th-generation Intel Core processors.
- For an LGA1151 MicroATX build: ASUS Intel PRIME H310M-A R2.0 LGA1151 DDR4 mATX Motherboard + I/O Plate pairs the lower listed price with MicroATX, DVI, VGA, and two memory slots.
- For an LGA1151 ATX board identified for 8th/9th-generation Intel: NEW MSI Z390-A PRO Motherboard LGA 1151 for 9th/8th Intel ATX M.2 USB 3.1 DDR4 has the broadest title-level connectivity callouts here, but also the highest listed price.
Listed price comparison

Decision matrix
Choose by desktop identity first. A Dell Precision 3650 Tower calls for the NDYHG 0NDYHG board, while a Dell XPS 8940 points to the K3CM7 427JK board. Those are direct model-specific matches rather than general build suggestions.
Choose by Intel platform label for a non-Dell-focused build. The ASUS Prime H310M-A R2.0 and MSI Z390-A PRO both carry LGA1151 and DDR4 in their names. The MSI additionally identifies 8th/9th-generation Intel support; the ASUS is identified as MicroATX.
Choose by the connections named for your setup. The ASUS calls out DVI and VGA. The MSI title names M.2 and USB 3.1. The Dell XPS 8940 board lists USB 3.1, USB 2.0, USB Type-C, M.2, SATA, PCIe, RJ-45, and headset ports.
Choose by condition where that matters to you. The two Dell Precision and ASUS entries are used, while the Dell XPS 8940 entry is new. The MSI entry is also marked new, although its description notes that the board has been opened for interface and slot testing.
Product notes
Dell Precision 3650 Tower Intel W580 Socket LGA1200 Motherboard NDYHG 0NDYHG
This board makes the most sense when the target machine is specifically a Dell Precision 3650 Tower. Its title gives the Precision model and LGA1200 socket, while the description also identifies DDR4 SDRAM. BIOS Unlocked, Computrace Unlocked, and MDM not enabled are additional stated configuration details that may be relevant to a replacement decision. The important limitation is condition: it is used. It is also described around the Precision 3650 Tower rather than as a broadly identified ATX or MicroATX build board, so its strongest case is a focused Dell replacement rather than a parts-list starting point.
Dell XPS 8940 Desktop Motherboard Intel 10th 11th Gen LGA1200 DDR4 K3CM7 427JK
For an XPS 8940 repair, this is the clearest match in the group because both the title and compatibility details name the Dell XPS 8940. It also explicitly identifies 10th- and 11th-generation Intel Core processors with an H470 chipset and states a 128GB maximum memory configuration. Its port list is extensive, including M.2, SATA, PCIe, USB Type-C, USB 3.1, USB 2.0, and RJ-45. The trade-off is its tightly specified role: the compatible-brand and compatible-model details are for Dell and for the XPS 8940, making that direct desktop match the central reason to select it.
ASUS Intel PRIME H310M-A R2.0 LGA1151 DDR4 mATX Motherboard + I/O Plate
The ASUS Prime H310M-A R2.0 is the straightforward pick for a buyer seeking the lowest listed price while shopping for an LGA1151 DDR4 MicroATX board. The title includes an I/O plate, and the stated connections are DVI and VGA. It has two memory slots, which gives the listing a clear, concrete layout detail for a compact-form-factor plan. Its limitation is the used condition, and its identity is firmly tied to the LGA1151 MicroATX designation. Choose it when those labels fit the build you have in mind, not solely because it sits at the low end of the price range.
NEW MSI Z390-A PRO Motherboard LGA 1151 for 9th/8th Intel ATX M.2 USB 3.1 DDR4
The MSI Z390-A PRO is aimed at a shopper who wants the stated combination of LGA1151, 8th/9th-generation Intel support, ATX form factor, M.2, USB 3.1, and DDR4. Those title-level details make it the most expansive match for someone already committed to that particular Intel generation and an ATX board. The clear constraint is the USD 172.21 listed price, the highest of the four. The description also says the board has been opened for testing, a detail worth factoring into a purchase where the title and condition identify it as new.
Final recommendation by use case
Pick the Dell Precision 3650 Tower board for a Precision 3650 Tower replacement, especially if its unlocked BIOS and Computrace details suit your situation. Select the Dell XPS 8940 board when the desktop is an XPS 8940 using the named 10th- or 11th-generation Intel Core processor range. For a compact LGA1151 DDR4 plan, the ASUS Prime H310M-A R2.0 brings MicroATX, DVI, VGA, and an I/O plate. Choose the MSI Z390-A PRO when your build calls for its stated ATX, M.2, USB 3.1, and 8th/9th-generation Intel labels.
