Motherboard Specs 2021 — Hp Fxn1 E93839

This motherboard was a staple in HP's 2021 desktop lineup, specifically designed for business and enterprise environments.

Overview and Identification

The HP FXN1 (often tagged with the layout code E93839) is a proprietary motherboard designed specifically for HP’s compact form factor desktops. It is not an off-the-shelf consumer board; rather, it is engineered for the HP ProDesk 600 G5 Desktop Mini and similar variants.

In 2021, this board represented the "business standard"—offering enough power for heavy multitasking and office management without the bulk of a traditional tower PC.

Conclusion

The HP FXM1 (E93839) is a capable but highly proprietary motherboard optimized for low-power, compact All-in-One PCs. In 2021, it was already a legacy platform (8th/9th Gen Intel), but it still offered adequate performance for home, office, or school use. It is not suitable for custom builds, gaming upgrades, or standard PC cases due to its unique power, I/O, and form factor requirements.

Verdict for 2021: Functional but outdated – only recommended if you are repairing an existing HP AiO or buying a cheap refurbished system. Avoid for new DIY projects.

2021-Specific Observations

Windows 11 Compatibility: In late 2021, HP released a BIOS update (version 2.15) enabling TPM 2.0 (fTPM) by default, making the FXN1 fully Windows 11 compatible despite being a 2018-era board.
GPU Limitations: The PCIe slot is limited to 75W (no external PSU cables). The best GPU you could install in 2021 without modding was a GTX 1650 or RX 6400 (low-profile for SFF).
BIOS Lock: The motherboard is locked to HP’s microcode. You cannot enable "Above 4G Decoding" or "Resizable BAR," so modern GPUs like the RTX 3060 run sub-optimally.
Used Market Value (2021): These boards sold for $40–$70 on eBay as pulls from recycled office PCs, often bundled with a Ryzen 3 2200G.

RAM

Uses DDR3 SODIMM (not desktop DDR3).
Max officially: 8GB (2x4GB). Unofficially in 2021, users confirmed 16GB (2x8GB) works if 1600MHz, low density.
Do not mix speeds – board defaults to slowest stick.

6. Form Factor

Type: HP Desktop Mini (DM) proprietary motherboard.
Dimensions: Approximately 6.9 x 6.9 inches (varies slightly by revision).
This board is incompatible with standard ATX, Micro-ATX, or Mini-ITX cases. It requires a specific HP chassis stand or bracket.

2021 Market Role

In 2021, this motherboard was not sold at retail. Replacement units were available through HP Parts Store (part # L90359-001 or similar) for $150–$250 USD. Third-party sellers on eBay/Amazon listed pulled or refurbished units for $80–$120. Overview and Identification The HP FXN1 (often tagged

4. Is This Motherboard Worth Using in 2021?

HP E93839 (FXN1) motherboard — 2021-style review

Summary

OEM HP ATX (proprietary) motherboard used in HP Compaq/Elite series (8200/8300/Pro/EliteDesk families). Typical revision: FXN1 / Rev. A (model E93839 / SP/PN variants).
Target: business desktops; not a consumer/gaming board. Strengths: reliability, compact integration, decent I/O for office use. Limitations: proprietary layout, older LGA1155 platform, limited upgrade path.

Key specifications (common across listings)

CPU socket: LGA 1155 (Intel 2nd/3rd‑gen Core / Xeon compatible depending on BIOS). Chipset commonly reported: Intel Q67 (desktop variants) or chipset family used in HP 8200/8300 series.
Memory: 4 × DDR3 UDIMM slots, dual‑channel (PC3‑10600 / DDR3‑1333 typical). Max RAM depends on HP BIOS—commonly 16–32 GB practical.
Expansion: 1× PCIe x16 (proprietary / full‑length), additional PCI/PCIe slots vary by revision/case (SFF vs ATX).
Storage: Multiple SATA ports (SATA II common), some OEM boards include eSATA on rear I/O.
Rear I/O: VGA, DisplayPort, DVI/HDMI (varies by model), multiple USB 2.0/3.0 ports, RJ‑45 LAN, audio jacks, PS/2 on some SKUs.
Onboard features: integrated audio, integrated Intel LAN, integrated GPU support via CPU graphics, TPM on some revisions.
Form factor: HP proprietary ATX-like layout (not guaranteed to fit all standard chassis without mounting differences).
Power connector: standard 24‑pin ATX + supplemental 4/8‑pin CPU power on many variants; SFF variants use proprietary power connectors.
Typical BIOS: OEM HP AMI/UEFI with limited user tuning and restricted CPU support lists.

Performance and compatibility

Performance reflects installed CPU (LGA1155). Common pairings in listings: Core i5‑6500 mentioned (note: i5‑6500 is LGA1151 — some listings mislabel CPUs; true compatible CPUs are 2nd/3rd gen LGA1155 like i5‑2500/i7‑3770). Verify CPU socket/chipset match before buying.
Good for office productivity, light multimedia, and legacy business tasks. Not suitable for modern high‑end gaming or heavy content creation.
BIOS and chipset limit support for newer CPUs, NVMe is unsupported natively (though NVMe via PCIe adapter may work in some revisions).

Build, reliability, and serviceability

Built for enterprise deployment: conservative power delivery, integrated cooling brackets, and long production runs.
HP OEM parts may vary (multiple SP/PN numbers seen). Used/refurbished market common; check seller photos, revision labels (FXN1, Rev A, SP/611796‑002 / 611835‑001 etc.).
Repairable but connectors and front‑panel pinouts may be proprietary—replacement in a non‑HP case can be fiddly.

Pros

Reliable OEM hardware for business desktops.
Adequate I/O and memory capacity for office workloads.
Readily available on secondary market as replacements or parts.

Cons

Aging LGA1155 / DDR3 platform with constrained upgrade path.
Proprietary layout/power connectors in some SKUs limit reuse in custom builds.
Limited BIOS tuning and feature set vs retail motherboards.
Watch for incorrect listings (misstated CPU/socket).

Buying advice (2021 / used‑market perspective)

Verify exact revision (FXN1 / Rev A) and confirm socket/chipset with seller photos and HP part numbers.
Confirm which HP model the board came from (8200/8300/EliteDesk) to match case and power connectors.
For a replacement in an HP machine, this board is a practical choice; for a custom build, prefer a standard ATX retail board for easier upgrades.
Expect typical used prices (varied by condition): low for defective/parts boards; mid range for tested working boards with shipping.

Verdict A solid OEM motherboard for maintaining older HP business desktops—dependable for office use and repairs, but obsolete for modern performance or upgrade flexibility. Buy as a replacement/repair part; avoid as the foundation for a new long‑term custom build.
