HP FXN1 E93839 is a proprietary motherboard commonly found in business-class desktops, such as the HP ProDesk 600 G3
series. It is designed for reliability in professional environments, offering a modified ATX form factor that fits specific HP chassis. Key Specifications
The FXN1 E93839 is built to support 6th and 7th Generation Intel technology, making it a solid choice for standard office tasks and moderate multitasking. Processor Support: Designed for the Intel LGA 1151
socket, supporting 6th Gen (Skylake) and 7th Gen (Kaby Lake) Core i3, i5, and i7 processors. 4x DDR4 DIMM slots
, typically supporting up to 64GB of RAM (Non-ECC, unbuffered). Expansion Slots: 1x PCIe x16 (for dedicated graphics) 1x PCIe x4 (open-ended or x16 physical) M.2 slots for NVMe SSDs and Wi-Fi cards Rear I/O Ports: 2x DisplayPort (some variants include VGA or HDMI) Multiple USB 3.0/3.1 Gen 1 ports and often 1x Networking: Integrated Gigabit Ethernet (RJ-45) Standard Line-in/Line-out jacks HP Support Community Usage and Compatibility Notes Proprietary Design: Because this is an HP OEM board, it uses non-standard power connectors
(typically 6-pin or similar) rather than the standard 24-pin ATX connector found on aftermarket power supplies. Chassis Fit:
It is intended for HP's Small Form Factor (SFF) or Microtower (MT) cases. Due to the unique mounting hole patterns and front-panel headers, it is difficult to install in a standard third-party PC case without significant modification. Reliability:
As a business-grade component, it is engineered for long-term stability and 24/7 operation.
If you are looking to buy or sell this part, you can find listings on marketplaces like or specialized parts retailers.

motherboard is a proprietary OEM board used in various HP business desktops, most notably the HP Compaq 8200 Elite and EliteDesk G3 series. Because HP uses the "E93839" designation across multiple generations, there are two primary variants with significantly different specs. Variant 1: LGA 1155 (Legacy/8200 Elite)
This older version is commonly found in 2nd-gen Intel systems like the HP Compaq 8200 Elite Go to product viewer dialog for this item. Socket: LGA 1155 (Socket H2). hp fxn1 e93839 motherboard specs
CPU Support: Intel Core i3, i5, i7 (2nd generation Sandy Bridge). Memory: 4 slots supporting DDR3 SDRAM.
Form Factor: Small Form Factor (SFF) or Ultra-Slim Desktop (USDT). Connectivity: VGA, DisplayPort, USB 2.0, RJ-45 Ethernet. Variant 2: LGA 1151 (Modern/G3 Series) This newer version is designed for 6th-gen Intel systems.
Socket: LGA 1151 (Note: Some listings mistakenly cite LGA 1155 for these CPUs, but the i5-6500 requires 1151).
CPU Support: Intel 6th Generation (Skylake), such as the i5-6500. Memory: 4 slots supporting DDR4 SDRAM. Form Factor: Modified/Proprietary ATX. Connectivity: DisplayPort, USB-C, USB 2.0, eSATA, SATA II. Critical Compatibility Notes
Proprietary Design: These boards are not standard ATX. They typically use proprietary power connectors (not a standard 24-pin) and specific mounting holes meant for original HP cases.
Power Supply: You must use an original HP power supply or a specialized adapter because they do not use standard ATX power standards.
Replacement Options: If you are looking for a replacement, merchants on eBay and Newegg offer used units ranging from $15 to $150 depending on the specific revision and included CPU.

Here is the complete breakdown of the HP FXN1 E93839 motherboard’s specifications.
| Feature | Specification | | :--- | :--- | | Manufacturer | Hewlett-Packard (HP) | | Model / PCB | FXN1 | | Part Number | E93839 | | CPU Socket | LGA 1150 | | Chipset | Intel H87 Express | | Compatible Processors | Intel Core i7-4xxx, i5-4xxx, i3-4xxx, Pentium G3xxx, Celeron G18xx (Haswell & Haswell Refresh only — NOT compatible with Broadwell/6th gen) | | Memory Slots | 2 x DDR3 DIMM (240-pin) | | Memory Type | DDR3 (Non-ECC, Unbuffered) | | Memory Speed | 1333 MHz, 1600 MHz (downclocks to 1333 depending on CPU) | | Max Memory Support | 16 GB (2 x 8GB modules) | | Memory Architecture | Dual-channel | | Expansion Slots | 1 x PCIe x16 (v2.0/v3.0), 1 x PCIe x1, 1 x PCI (32-bit legacy) | | Storage Interfaces | 4 x SATA 3.0 (6 Gb/s), 1 x SATA 2.0 (3 Gb/s — often for optical drive) | | M.2 Slot | No | | Rear I/O | 1 x PS/2 (keyboard), 1 x VGA, 1 x DVI-D, 1 x HDMI, 4 x USB 2.0, 2 x USB 3.0, 1 x RJ45 Ethernet, 3 x Audio jacks | | USB Headers (Internal) | 2 x USB 2.0, 1 x USB 3.0 | | Audio Codec | Realtek ALC662 (5.1 channel HD Audio) | | LAN / Ethernet | Realtek RTL8111HSH (Gigabit) | | BIOS | AMI (American Megatrends) with HP UEFI interface | | Power Connectors | 1 x 24-pin ATX (proprietary pinout possible), 1 x 4-pin CPU (12V) |
This is the most critical section. The HP FXN1 E93839 uses a proprietary power connector layout. While it accepts a standard 24-pin ATX plug, the pinout is often different from standard. Plugging in a standard retail PSU without an adapter can destroy the motherboard. HP FXN1 E93839 is a proprietary motherboard commonly
Recommended PSU Upgrade Path: Replace the motherboard altogether if you want a standard ATX build. Otherwise, stick to a low-power GPU that runs off the PCIe slot alone.
| Symptom | Likely Cause | Fix | | :--- | :--- | :--- | | No power, LED off | Dead proprietary PSU or motherboard short | Replace with HP OEM PSU | | 3 beeps, no display | Bad RAM or unsupported memory module | Use only 2Rx8 or 1Rx8 DDR3, no ECC | | 5 short beeps | CPU not supported or BIOS corruption | Clear CMOS (jumper near battery) | | SSDs slow | Running on SATA 2.0 (black port) | Move SSD to white SATA 3.0 port | | GPU not detected | PCIe slot in Gen 1 mode (BIOS) | Update BIOS to latest HP revision |
The HP FXN1 E93839 is a durable, business-grade Intel LGA 1155 motherboard with a unique set of proprietary quirks. Its key specifications include the Q65 chipset, support for 2nd gen Core processors, 16GB DDR3, and a confusing power connector. If you are repairing an old HP desktop, understanding these specs will save you from buying incompatible parts. If you are building a new system, skip this board—its proprietary nature is more hassle than it’s worth. But for tinkerers and budget recyclers, it remains a surprisingly capable foundation.
