With these upgrades, the HP FXN1 E93839 can still run Windows 11 (with bypass), office suites, 1080p video, and esports titles like League of Legends or CS:GO comfortably.
However, for modern AAA gaming or video editing, this platform is obsolete. The LGA 1150 socket reached end-of-life in 2015. If you are building from scratch, look for used Ryzen or 8th-gen Intel systems instead.

HP E93839 (FXN1) is a proprietary motherboard used primarily in HP business desktops, most notably the HP Compaq 8200 Elite Small Form Factor (SFF)
. Users generally review it as a reliable, stable component for "casual computing" and business environments. HP Support Community Key Specifications Form Factor: Modified ATX / Small Form Factor (SFF). Socket Type: LGA 1155 (Socket H2). Intel Q67 Express. 4 slots supporting DDR3 SDRAM (up to 32GB).
Integrated Intel HD Graphics; includes 1x PCIe x16 slot for low-profile dedicated GPUs. I/O Ports: hp fxn1 e93839 motherboard specs
10x USB 2.0 (total), DisplayPort, VGA, Ethernet (RJ-45), and audio jacks. Supports SATA II/III interfaces. Performance and Compatibility CPU Support:
Designed for 2nd Generation Intel Core processors (Sandy Bridge), such as the i3-2100, i5-2400, and i7-2600. Reliability: Feedback from AliExpress
indicates it is a durable unit for heavy office tasks but lacks modern features like USB 3.0 or NVMe slots. Upgradability:
Limited by the SFF case and proprietary power connectors. It typically uses a 240W power supply, meaning only low-power, low-profile graphics cards (like the GT 730 or GT 1030) are recommended. HP Support Community Pros & Cons
Highly stable for business use, affordable replacement part, and features four RAM slots for decent memory capacity.
Proprietary power connectors (making standard PSU upgrades difficult), limited to older CPU generations, and lacks HDMI (requires DisplayPort adapter). for a failed board or trying to a specific HP desktop model?

This is the most important section if you are replacing the motherboard.
The HP FXN1 E93839 does not use a standard 24-pin ATX power connector. Instead, it uses:
The pinout of the 6-pin connector is non-standard. Adapters exist (e.g., 24-pin to 6-pin HP), but you must ensure the adapter matches the HP proprietary standard (often used with HP part number 5188-2628). Using a standard PSU without an adapter will not work and may short the board.
When you open a prebuilt desktop PC from a major manufacturer like HP, you don’t usually find a standard off-the-shelf motherboard. Instead, you find custom boards designed specifically for that chassis and power supply. The HP FXN1, also identified by the spare part number E93839, is one such proprietary motherboard.
If you have acquired this board (either inside an HP Pavilion or as a replacement part), you need to understand exactly what it supports. This article provides a deep dive into the technical specifications, CPU compatibility, RAM limitations, expansion slots, and common troubleshooting tips for the HP FXN1 (E93839).
Despite being a budget OEM board, the FXN1 offers three expansion slots: Spec sheet summary for quick reference:
GPU Upgrade Warning: The PCIe slot is physically x16 but may run at PCIe 2.0 speed (5 GT/s) depending on the CPU, not PCIe 3.0. A modern budget GPU will still work but may see a 5-10% performance loss.
| Symptom | Likely fix | |---------|-------------| | No power, LED off | Check DC jack solder joints (cracks common). Replace power brick. | | Boots but no display | Reseat RAM. Clear CMOS (short JCMOS). Test external HDMI. | | M.2 SSD not detected | Update BIOS. Use SATA M.2 not NVMe. | | Overheating | Clean CPU fan heatsink (dust clogs AIO intake). Repaste. | | USB ports dead | Check internal USB header cable; otherwise chipset failure. |
The HP FXN1 (part number E93839) is a micro-ATX (uATX) form factor motherboard primarily found in HP Pavilion desktop PCs from the mid-2010s, particularly the HP Pavilion 500, 550, and 500-300 series. It was designed for Intel’s 4th generation (Haswell) and select 5th generation (Haswell Refresh) processors.
This board is a classic example of HP’s cost-optimized engineering. It provides the essential features for a home or office PC but lacks the high-end overclocking, multiple GPU slots, or extensive RGB headers you would find on a retail board like an ASUS or Gigabyte.
