This is the only extended ATX board in the pool, which makes it the best fit for a standard workstation tower rather than a rack chassis. It pairs the Intel C741 chipset with the LGA4677 socket and is the most compact pick in this list.
Pros
- Extended ATX form factor fits standard tower cases, unlike the CEB and proprietary boards in this pool
- Intel C741 chipset, the same platform used by the other LGA4677 boards here
- Single-socket LGA4677 support for 4th Gen Intel Xeon Scalable processors
- The only pick that states its form factor as ATX
Cons
- DDR5 RAM type not stated in the listing, unlike the other three picks
- Single-socket design limits core counts versus the dual-socket boards in this list
- Supermicro branding implies server-grade reliability, but no independent testing is available
Good fit if
- Builders assembling a single-socket Xeon workstation in a standard tower case
- Those who want a board from a established server maker without needing dual sockets
Skip if
- You need more than one LGA4677 processor for heavily threaded workloads
- You require DDR5 RAM support explicitly confirmed in the listing
Verdict: The most practical LGA4677 board for a standard workstation build, though dual-socket users should look elsewhere.

How the picks were chosen
We started with a pool of 4 LGA4677 motherboards listed on the storefront, all matched by socket type. We shortlisted by three rules: the board must state LGA4677 support in the listing, it must come from an established server or workstation maker, and it must be in new condition. We kept every pool entry because the pool held fewer than 12 listings. We compared form factor, chipset family, RAM type, and stated PCIe and storage support from the product listings. Prices shown are live and read from the store listing; they change over time. No unit was tested or benchmarked by the site.
Picking the right one for you
Socket and processor compatibility
LGA4677 is Intel's socket for 4th Gen Xeon Scalable processors, and all four boards in this pool state support for that family. Check that your specific Xeon model is listed as compatible by the board maker, because some CPUs may require a specific chipset or BIOS version. The Intel C741 chipset, mentioned on the Supermicro X13SEI-F-B, is the platform for these server boards, providing PCIe lanes and memory channels for workstation workloads. See the Intel chipset page in the sources for the broader server chipset lineup.
Form factor: ATX, CEB, or proprietary
The Supermicro X13SEI-F-B is the only board here that states an ATX form factor, which means it fits most standard tower cases. The ASRock Rack SPC741D8 uses CEB, a size between ATX and E-ATX, common in rack chassis but often incompatible with consumer cases. The two dual-socket boards from GIGABYTE and Supermicro do not list their form factors, so measure your chassis before ordering. Server boards often use proprietary layouts, so verify standoff positions and rear I/O openings.
Memory: DDR5 support and capacity
Three of the four picks state DDR5 RAM support, while the Supermicro X13SEI-F-B does not list its RAM type. DDR5 is the current standard for 4th Gen Xeon Scalable systems, offering higher bandwidth per DIMM than DDR4. For memory-heavy jobs like virtualization or large datasets, prefer boards with explicit DDR5 support and check how many DIMM slots are available. The listings here do not state slot counts, so confirm with the seller or the maker's spec sheet before buying.
Single vs. dual sockets
Single-socket boards like the Supermicro X13SEI-F-B and ASRock Rack SPC741D8 are simpler to build and cost less on CPU and cooling, but they limit you to one processor. Dual-socket boards, such as the GIGABYTE MS73-HB1 and Supermicro X13DEI-O, double the core count for heavily threaded tasks like 3D rendering or data analytics. Match the socket count to your workload; a second CPU only helps if your software scales across sockets.
Expansion and connectivity
None of the listings in the pool state PCIe generation, M.2 slots, SATA ports, or network controllers, so you will need to check the manufacturer's spec page for those details. Server boards often include multiple PCIe x16 slots for GPUs and high-speed NICs, plus onboard 10GbE networking, but that varies by model. For a workstation, prioritize boards with enough PCIe lanes for your GPU and storage needs. The USB4 and Wi-Fi standards pages in the sources can help you assess what modern connectivity looks like, but confirm what each board offers before purchase.
Operating system and software compatibility
Windows 11 requires a 1 GHz dual-core processor, 4 GB RAM, and 64 GB storage, which every LGA4677 Xeon system will easily meet, but server boards often target Linux or Windows Server. Check that the board's chipset and NIC drivers support your chosen OS. For Windows 11, the TPM 2.0 and Secure Boot requirements apply, so verify the board includes a TPM header or module. See the Microsoft specifications page in the sources for the full requirements list.
Questions
What processors fit an LGA4677 motherboard?
LGA4677 sockets accept 4th Gen Intel Xeon Scalable processors, which include a range of SKUs from the Bronze and Silver families up to Platinum and Gold models. All four boards in this guide state support for this generation. The exact CPU model you can use depends on the board's chipset and BIOS, so check the maker's compatibility list before buying.
Can I use DDR4 memory on an LGA4677 board?
Most LGA4677 boards, including the GIGABYTE MS73-HB1, the Supermicro X13DEI-O, and the ASRock Rack SPC741D8, support DDR5 memory. The Supermicro X13SEI-F-B does not state its RAM type, so verify with the seller. If you plan to reuse DDR4 modules, look for a board that explicitly lists DDR4 support, which is rare on this socket.
What is the difference between CEB and ATX form factors?
ATX is the standard size for consumer cases, measuring roughly 12 by 9.6 inches. CEB, or Compact Electronics Bay, is a slightly larger format, about 12 by 10.5 inches, used in some server chassis. The Supermicro X13SEI-F-B is ATX, while the ASRock Rack SPC741D8 is CEB. Check your case's specifications to ensure the board fits, especially for the dual-socket boards with unstated form factors.
Do I need two CPUs for a workstation?
Not always. Single-socket boards like the Supermicro X13SEI-F-B and ASRock Rack SPC741D8 are sufficient for many tasks, from software development to single-GPU rendering. Dual-socket boards, such as the GIGABYTE MS73-HB1 and Supermicro X13DEI-O, double the core count, which helps if your applications are designed to use multiple sockets. Review your software's scaling behavior before deciding.
Will these motherboards support Windows 11?
Yes, most likely, because the minimum requirements are a 1 GHz dual-core processor, 4 GB RAM, and 64 GB storage, all easily exceeded by Xeon systems. However, Windows 11 also requires TPM 2.0 and Secure Boot. Server boards often include a TPM header, but you may need to install a TPM module separately. Check the board's manual for TPM support and see the Windows 11 specifications in the sources.
