Applications

The P4P800 SE was part of ASUS's mainstream 865PE-based lineup released in 2003, targeting home and office desktop builds around Intel's Pentium 4 Northwood and Prescott processors. The Intel 865PE chipset supported dual-channel DDR memory and AGP 8x, positioning it as a step up from the entry-level 865G (which included integrated graphics) while remaining affordable. These boards are still sought after for legacy Pentium 4 system builds, retro computing projects, and replacement motherboards in older workstations or industrial PCs that ran Socket 478 hardware. The P4P800 family was one of ASUS's best-selling platforms of the era, known for broad compatibility and solid BIOS support across the Socket 478 Pentium 4 range.
