MS-7826 motherboard , often referred to by its internal HP code name "Kaili," is a high-performance OEM board manufactured by MSI specifically for HP's premium desktop lines like the Envy 700 and Envy Phoenix 810 series. Because it is an OEM (Original Equipment Manufacturer) part, HP does not provide a standalone user manual in the traditional retail sense; instead, technical details are found within broader system guides and community-documented pinouts. Core Hardware Specifications
Built on the Intel Z87 chipset, this motherboard was designed for fourth-generation (Haswell) processors, providing a robust platform for gaming and media creation.
Processor Support: LGA 1150 socket, compatible with Intel Core i3, i5, and i7-4xxx series CPUs. Memory: Features four DDR3 DIMM slots. Maximum Capacity: 32 GB (4x 8 GB sticks).
Speeds Supported: PC3-10600 (1333 MHz) and PC3-12800 (1600 MHz) non-ECC memory. Expansion Slots: 1x PCI Express x16 (Gen 3.0) for high-end graphics cards. 3x PCI Express x1 (Gen 2.0) for peripheral cards.
1x Mini Card slot (half-length), typically used for integrated Wi-Fi/Bluetooth modules. Internal Connectivity and Headers
The lack of a formal manual often makes case-swapping difficult due to proprietary pin configurations.
Front Panel Header: The pins for the power switch, HDD LED, and Power LED are located together but follow a specific layout often documented by the HP Support Community. Note that LEDs are polarity-sensitive; if they don't light up, the wires may need to be reversed.
Storage: Includes multiple SATA ports. Some versions also feature an mSATA port, though there is community debate regarding its shared bandwidth with other SATA interfaces.
Power: Most versions use a standard 24-pin ATX power connector and a 4-pin CPU power connector, though users should always verify pinouts before upgrading to a third-party PSU to avoid electrical damage. Troubleshooting and Official Documentation
