PRODUCT DESCRIPTION
ASUS ExpertBook B3 B3405CCA-LY1651X (90NX08L1-M01XR0) - Intel Core Ultra 5 225H / 16GB / 512GB SSD - 3 Years Onsite Warranty
ASUS ExpertBook B3 (B3405) with Intel Core Ultra 5 225H
The ASUS ExpertBook B3 B3405CCA-LY1651X (part number 90NX08L1-M01XR0) is a 14-inch business laptop built on the B3405 chassis and configured with the Intel Core Ultra 5 225H processor, 16GB of DDR5 memory, a 512GB PCIe 4.0 NVMe SSD and Windows 11 Pro. It is finished in Gentle Grey and supplied with a carry bag and a wireless optical mouse in the box.
The B3 range sits between the entry-level ExpertBook B1 and the higher-specification ExpertBook B5 in the ASUS business line-up. It is aimed at office staff, finance and operations teams, and hybrid workers in Singapore who need a dependable, serviceable laptop with full-size ports and a 3-year onsite warranty.
Intel Core Ultra 5 225H with a Built-in NPU
The Intel Core Ultra 5 225H has 14 cores and 14 threads and boosts up to 4.9 GHz, with integrated Intel Graphics and an Intel AI Boost NPU rated at up to 13 TOPS. The NPU handles supported on-device AI workloads such as Windows Studio Effects during video calls, leaving the CPU cores free for the applications you are working in. If you need a little more headroom for heavier spreadsheets and multitasking, the B3405CCA-LY1653X sibling uses the Intel Core Ultra 7 255H in the same chassis.
14-inch WUXGA 16:10 Anti-Glare Display
The 14-inch WUXGA panel (1920 x 1200) uses a 16:10 aspect ratio, giving more vertical space for documents, email and spreadsheets than a 16:9 screen of the same width. It is rated at 300 nits with an anti-glare finish and wide 170-degree viewing angles, and is a non-touch panel.
Upgradeable Memory and a Second SSD Slot
Memory is fitted in DDR5 SO-DIMM slots (two in total), so the 16GB can be expanded later rather than being soldered to the board. Storage is a 512GB M.2 2280 PCIe 4.0 NVMe SSD, and the chassis also has an M.2 2230 PCIe 4.0 slot with an SSD housing for adding a second drive.
Full-Size Office Ports: RJ45, HDMI 2.1 and USB-C
You get a built-in RJ45 Gigabit Ethernet port, HDMI 2.1, two USB 3.2 Gen 2 Type-C ports with display output and power delivery, two USB 3.2 Gen 1 Type-A ports, a microSD card reader and a 3.5mm combo audio jack. Wireless is Wi-Fi 6E (triple band, 2x2) with Bluetooth 5.4.
Security and Durability for Business Fleets
A fingerprint sensor is built into the power key for Windows Hello sign-in, the 1080p webcam has a physical privacy shutter, and the platform includes TPM 2.0, Microsoft Secured-core PC features, Intel BIOS Guard and Boot Guard, and a Kensington Nano security slot. The chassis has an aluminium lid and is tested to US MIL-STD 810H (24 procedures). ASUS lists EPEAT Gold with Climate+, ENERGY STAR 8.0 and TCO Certified for this configuration.
Warranty and Local Supply
ASUS backs this laptop with 3 years of onsite service on a next-business-day basis, and the battery is covered for the same 3 years. SourceIT supplies the B3405CCA-LY1651X with a GST invoice. For volume orders or a comparison against other ExpertBook models, email sales@sourceit.com.sg.

Connectivity & Setup / Security Features
Docking and External Displays
Both USB 3.2 Gen 2 Type-C ports support display output and power delivery, so a USB-C dock or monitor can charge the laptop and carry video over a single cable. The HDMI 2.1 port drives a second monitor directly.
Wired and Wireless Networking
The built-in RJ45 Gigabit Ethernet port means no dongle is needed on a wired office LAN. Wi-Fi 6E adds access to the 6GHz band on compatible access points, and Bluetooth 5.4 covers headsets and peripherals.
First-Time Setup
The laptop ships with Windows 11 Pro, so it can join Microsoft Entra ID or an Active Directory domain and be managed with Intune or Group Policy. MyASUS is preinstalled for driver and BIOS updates, battery health charging and system diagnosis, and ASUS AI ExpertMeet is included for meeting transcription and summaries (AI features require 12GB of memory or more, which this 16GB configuration meets).
Security Features
Windows Hello sign-in is handled by the fingerprint sensor in the power key. TPM 2.0 stores BitLocker keys in hardware, and Microsoft Secured-core PC, Intel BIOS Guard, Intel Boot Guard and BIOS self-recovery protect the firmware. Absolute Persistence 2.0 (Computrace) is supported for asset tracking, and the Kensington Nano slot accepts a cable lock.
