ASUS ExpertBook P3 • P3406CCA • Misty Grey
A business laptop with room for memory and storage growth.
This ExpertBook P3 P3406CCA configuration combines an Intel Core Ultra 5 225H, 16 GB of DDR5 memory and a 512 GB SSD with Windows 11 Pro. The 14-inch 1920 × 1200 anti-glare display provides a 16:10 working area. Its platform brings two memory sockets, two SSD positions and a mix of wired network, USB and display connections to a portable Misty Grey design.

Processor and AI
A 14-core foundation for the working day.
The Core Ultra 5 225H has fourteen cores and fourteen threads, an 18 MB cache and up to 4.9 GHz turbo frequency. Intel AI Boost provides a dedicated NPU, which ASUS rates at up to 13 TOPS for this processor option. Those are component specifications, not a guarantee that every business application uses the NPU or achieves a particular speed. Integrated graphics use shared system memory.
Display
A practical 16:10 workspace.
The supplied configuration is listed with a 14-inch WUXGA 1920 × 1200 anti-glare wide-viewing-angle display. ASUS’s matching WUXGA platform option is a non-touch, LED-backlit panel rated at 300 nits and 45% NTSC. It is distinct from the family’s 2560 × 1600, 400-nit wide-gamut option; those higher-resolution display specifications are not included by implication.
Memory upgrades
Two sockets, with supported population limits.
The laptop includes 16 GB of DDR5 memory. ASUS documents two SO-DIMM sockets, including those already in use. Current global specifications and the manufacturer’s platform announcement describe up to 96 GB through supported self-upgrades, while factory configurations may be limited to 64 GB. Check the supplied module population and approved memory specifications before buying an upgrade.
Storage
A supplied SSD and a second form factor to plan around.
The installed storage capacity is 512 GB. The P3406CCA platform has one M.2 2280 PCIe 4.0 x4 position and one M.2 2230 PCIe 4.0 x4 position, including the position already occupied. The two lengths are not interchangeable without the correct mounting arrangement. Confirm the installed drive location, required screws and supported capacities before adding or replacing storage.
Connections
USB-C display support alongside wired Ethernet.
ASUS lists one Thunderbolt 4 port compatible with USB4 and display/Power Delivery, plus one USB 3.2 Gen 2 Type-C port with display/Power Delivery. Two USB 3.2 Gen 1 Type-A ports, Gigabit Ethernet, HDMI 2.1 TMDS and a 3.5 mm combination audio jack cover common desk connections. The shared B/P-series manual illustrates more than one port layout; use the exact P3406CCA specification when choosing a dock or cable.
Durability and security
Understand what the manufacturer’s standards describe.
ASUS documents MIL-STD-810H testing for this platform and describes ExpertGuardian security with NIST SP 800-155 alignment. The security specification includes firmware TPM support, boot and BIOS protections and a physical security-lock provision. Optional fingerprint and IR-camera features vary by configuration. Testing and security features do not make the laptop immune to damage, data loss or every threat; warranty exclusions and organisation settings still apply.
Battery and physical planning
Confirm the battery and adapter supplied with this pack.
The platform offers 50 Wh and 70 Wh battery configurations; the exact capacity is not stated for this supplied SKU. ASUS documents 65 W USB-C charging, and the manual notes that a lower-wattage source can take longer to charge. Confirm adapter inclusion and battery capacity before ordering. The platform footprint is 316 × 227.8 mm, with weight and thickness varying by configuration; no fixed runtime is promised.
Windows and support
Use the exact model when selecting downloads.
Windows 11 Pro is included in this configuration. The exact P3406CCA support selector provides model-specific drivers, firmware and documentation; check the operating-system release and each package’s requirements. Keep the unit’s serial number and warranty documents for local support and service confirmation. Bundled bags, mice, camera options and warranty terms from overseas configurations should not be assumed for this pack.
