Socket LGA 775 platform board

The ASUS P5QL/EPU is an ATX motherboard built around the Intel P43 chipset for LGA 775 processors. It accepts DDR2 memory up to 16 GB total capacity. The board ships with an I/O shield and one SATA cable for basic storage connectivity. This unit is intended for users maintaining or repairing legacy desktop systems.

EPU energy management under load

The on-board EPU engine monitors real-time power draw and adjusts phase operation to reduce waste during sustained workloads. This helps keep component temperatures stable when the system runs for extended periods. The design targets efficient operation without requiring additional software configuration.

Replaces damaged or missing LGA 775 boards

This motherboard serves as a direct swap for failed P43 or similar chipset boards in existing chassis. The jump is worthwhile when the original board no longer posts or has damaged slots. Buyers needing integrated graphics output or newer memory standards should look elsewhere.

Questions about this item

How much heat and power does the ASUS P5QL/EPU draw when running continuously?

The board uses the Intel P43 chipset and supports DDR2 memory up to 16 GB, so its power draw and heat output depend on the specific LGA 775 processor and memory configuration you install.

What other components must I already own for this motherboard to function?

You will need an LGA 775 processor, DDR2 memory modules, a compatible ATX power supply, storage drives with SATA connections, and a case that fits an ATX form factor.

Will my existing SATA drives and DDR2 memory work with this board?

Yes, the board provides SATA ports for your current drives and four DDR2 slots that accept up to 16 GB total, so older SATA storage and DDR2 modules can be reused directly.
