AsRock E3C252D4U Micro-ATX Server Motherboard
The AsRock E3C252D4U is a single-socket Micro-ATX server motherboard built around an LGA1200 (Socket H5) CPU socket — a compact board for integrators building rackmount or small-form-factor servers where full-size ATX real estate isn't available. At 11.40 x 12.20 in, it fits standard Micro-ATX server chassis and 2U/3U rack enclosures without modification, and the E3C252D4U designation keeps it identifiable across quotes, BIOS labeling, and asset tags.
Overview
This is a bare motherboard, not a full server — expect to pair it with your own CPU, memory, storage, and chassis. The Micro-ATX footprint (11.40 x 12.20 x 2.90 in) targets deployments where rack density matters more than expansion slot count, such as edge servers, NVR back-ends, or branch-office compute nodes. Manufactured in China (country of origin CN), consistent with the broader AsRock server board lineup.
Key Features
- Single Socket H5 (LGA1200): supports LGA1200-based server and workstation CPUs — confirm exact CPU compatibility against your target processor before ordering, since this listing does not include a validated CPU support list.
- Micro-ATX form factor: the 11.40 x 12.20 in footprint drops into standard Micro-ATX server cases and many compact rack chassis, useful when 2U or shallow-depth enclosures rule out full ATX boards.
- 2.70 lb board weight: light enough that it doesn't add meaningful load budget concerns in multi-unit rack builds, though always weigh the completed chassis, not just the board.
- 2.90 in max component height: relevant when clearance-checking against low-profile rack lids or 2U chassis — verify heatsink and expansion card clearance against this figure.
Integration & Compatibility
Because detailed chipset, memory, and I/O specifications aren't included in the verified data for this listing, confirm RAM type/capacity, PCIe slot configuration, SATA/NVMe count, and BMC/IPMI support directly against the AsRock server documentation for the E3C252D4U before finalizing a build-out. Pair it with a chassis and power supply rated for Micro-ATX server boards, and check the CPU socket (LGA1200) against your intended processor generation — LGA1200 covers specific Intel server/workstation SKUs, not the full Xeon range.
This board is best suited for integrators who already have a target CPU and chassis in hand and need a compact, rack-friendly Micro-ATX server motherboard to complete the build — the E3C252D4U's dimensions and single-socket LGA1200 layout are the deciding factors here, not a long feature list.
Frequently Asked Questions
Q: What CPU socket does the E3C252D4U use?
A: Single Socket H5 (LGA1200).
Q: What form factor is the E3C252D4U?
A: Micro-ATX, measuring 11.40 x 12.20 x 2.90 in.
Q: How much does the E3C252D4U weigh?
A: 2.70 lb.
Q: Where is the E3C252D4U manufactured?
A: China (country of origin CN).
The E3C252D4U is a single-socket LGA1200 Micro-ATX server board — I get asked about these when someone's cramming server compute into a 2U or shallow rack chassis and a full ATX board just won't clear.
Technical Highlights:
- Socket H5 (LGA1200): single-socket layout keeps the board compact — no dual-socket QPI/UPI routing eating board space, which is part of why AsRock can hold this to a 11.40 x 12.20 in footprint.
- 11.40 x 12.20 x 2.90 in Micro-ATX footprint: fits standard Micro-ATX server chassis; the 2.90 in height figure is worth checking against your chassis lid clearance before you order heatsinks.
- 2.70 lb board weight: light for a server board, which matters if you're stacking multiple units in a rack and tracking cumulative shelf load.
Deployment Considerations:
- This is a bare board — verify RAM type, PCIe slot layout, and storage I/O against AsRock's own documentation for the E3C252D4U before locking in a parts list, since those details aren't part of the verified spec set here.
- LGA1200 covers a specific generation of Intel processors — confirm your target CPU is on that list before you buy, since socket compatibility alone doesn't guarantee BIOS/microcode support.
Best fit: integrators building compact single-socket rack or edge servers — think branch-office NVR back-ends or small compute nodes — who already have an LGA1200 CPU and Micro-ATX chassis picked out and need a board that fits both.
