Wired Ethernet, No Dongle Needed

The built-in RJ45 Gigabit Ethernet port plugs straight into a wired office network without a USB adapter or dock — a genuine practical difference from the ExpertBook Ultra B9406 and ExpertBook P5405 ranges we also carry, neither of which has one. Both Thunderbolt 4 ports support DisplayPort output, Power Delivery charging and high-speed data transfer, so a dock, monitor or charger can connect through either port.

Wi-Fi 7 for Dense Office Networks

Wi-Fi 7 (triple band, 2x2) offers materially higher throughput and lower latency than Wi-Fi 6 or 6E on a compatible access point, particularly useful on a busy office floor with many concurrent devices. Bluetooth 5.4 handles wireless peripherals and headsets.

Microsoft Secured-Core PC and the On-Device NPU

Microsoft Secured-core PC certification means the firmware, hardware and OS layers meet a specific hardware-backed security baseline against firmware-level attacks — relevant for organisations with a formal device security policy. The Intel AI Boost NPU (up to 13 TOPS) handles lighter on-device AI tasks such as Windows Studio Effects on video calls without loading the CPU cores.

Windows Hello and the Physical Camera Shutter

The power-key fingerprint sensor supports Windows Hello for fast sign-in, and the physical camera shutter mechanically blocks the webcam lens when not in use, so it cannot be activated without the user's knowledge regardless of what software requests access. TPM 2.0 stores BitLocker recovery keys in hardware, meeting most Singapore corporate IT policy baselines.

SourceIT carries the ExpertBook B3405CCA alongside this B5405CCA, both built on the Intel Core Ultra 7-255H processor with RJ45 Ethernet built in. Email sales@sourceit.com.sg quoting the part number to check stock and lead time.

Choosing Between the B5405 and B3405 Chassis

Both share the same Intel Core Ultra 7-255H processor, 16GB DDR5 memory, 512GB SSD and built-in RJ45 Ethernet. The difference is the display: this B5405 range uses a sharper WQXGA (2560 x 1600) panel with 100% sRGB coverage, while the B3405 range uses a WUXGA (1920 x 1200) panel — adequate for general office work, but a visibly lower resolution and colour accuracy for anyone doing detailed spreadsheet or image work. The B3405 chassis also weighs slightly more, at a starting 1.45 kg against the B5405's 1.38 kg.

ASUS hosts the official product and specification pages for this model family. The links below are ASUS's current pages for the B5405 chassis.

Does this laptop have a wired Ethernet port?

Yes — a built-in RJ45 Gigabit Ethernet port, no dongle or dock required. This is a genuine practical difference from the newer ExpertBook Ultra B9406 and ExpertBook P5405 ranges we also carry, which have no Ethernet port at all.

Can the memory or storage be upgraded later?

Yes — memory is 16GB DDR5 in a SO-DIMM slot, upgradeable to a documented maximum of 32GB, unlike the soldered-memory ExpertBook Ultra B9406 and ExpertBook P5405 ranges. The 512GB SSD can also be replaced or supplemented; ask us about dual-drive configurations if you need higher capacity.

How does this compare with the ExpertBook B3405CCA in your catalogue?

Same processor (Core Ultra 7-255H), memory, storage and Ethernet port. The main difference is the display: this B5405 range has a sharper 2560 x 1600 WQXGA panel with full sRGB coverage, while the B3405 range uses a 1920 x 1200 WUXGA panel.

Does it have a discrete graphics card?

No — graphics run on the integrated Intel Graphics built into the Core Ultra 7-255H processor, sufficient for office, video-conferencing and multi-monitor work but not gaming or GPU-accelerated rendering.

What is Microsoft Secured-core PC, and does it matter for a standard office deployment?

It is a hardware-backed security certification covering firmware, hardware and OS layers against firmware-level attacks. It is not required for standard office use, but it is a genuine plus for organisations with a formal device security policy or regulated data handling requirements.

Is the NPU on this chip as capable as the one in the newer ExpertBook P5405 range?

No — this Core Ultra 7-255H's NPU is rated up to 13 TOPS, materially smaller than the 47 TOPS NPU in the Core Ultra 7-258V used in our ExpertBook P5405 listings, and this laptop does not carry Copilot+ PC certification. It still handles lighter on-device AI tasks such as Windows Studio Effects on video calls.

What durability or build standard does this chassis meet?

ASUS does not publish a MIL-STD durability certification for this specific B5405CCA configuration in the documentation we could verify — if military-grade durability testing is a requirement for your deployment, the ExpertBook P-series carries MIL-STD 810H certification and may be the better fit; ask us to confirm.

Does it come with a Singapore warranty and a GST invoice?

Yes. Every ASUS ExpertBook B5 B5405CCA-NZ0226X sold by SourceIT comes with local Singapore support and a GST invoice; ASUS backs this model with a 3-year international warranty including local carry-in and onsite service.
