ASUS ExpertBook Ultra B9406CAA-TH0910X U7-356H/ 32GB/ 1TB SSD
PRODUCT DESCRIPTION
ASUS ExpertBook Ultra B9406CAA-TH0910X (90NX09J2-M010D0) - 3 Years International Warranty
ASUS's Flagship Business Ultraportable, Finished in Jet Fog
Jet Fog is the darker of the two exterior finishes ASUS offers on the ExpertBook Ultra B9406 chassis, and the B9406CAA-TH0910X carries it on the same top-tier specification as our Morn Grey listing: Intel Core Ultra 7-356H processor, 32GB of soldered LPDDR5X memory, a 1TB PCIe 4.0 NVMe SSD and a 14-inch Tandem OLED touchscreen at WQXGA+ resolution (2880 x 1800). Windows 11 Pro comes preinstalled, and the whole machine is built on a magnesium-lithium alloy chassis that keeps starting weight under 1 kg.
This is ASUS's current-generation "Panther Lake" ExpertBook platform, sitting above the ExpertBook P3, P5 and B-series ranges we also carry, both in specification and in price. If your organisation runs on a dark-finish device policy or simply prefers Jet Fog for executive-facing hardware, this configuration gives you the full top-tier B9406 spec sheet without compromise.
What "Tandem OLED" Actually Buys You Over a Standard OLED Panel
The panel is 14 inches, 2880 x 1800 (WQXGA+, 16:10), touch-enabled, anti-glare, with a 600-nit typical brightness that climbs to 1400 nits for HDR highlights, inside a 91% screen-to-body bezel. A conventional single-layer OLED panel trades brightness for contrast; Tandem OLED stacks two emissive layers to recover a meaningfully higher sustained brightness while keeping OLED's per-pixel black levels and colour accuracy. In a bright Singapore office with overhead fluorescents or a window-facing desk, that is the difference between a screen that stays legible all day and one that needs the blinds drawn.
Core Ultra 7-356H and the NPU Underneath It
The Core Ultra 7-356H puts performance cores, efficiency cores and low-power efficiency cores on a single die alongside a dedicated Intel AI Boost NPU. In day-to-day use that NPU is what handles Windows Studio Effects on a video call and local AI acceleration inside Copilot-enabled Microsoft 365 apps — work that would otherwise land on the CPU cores you are actively typing into. Graphics run on the integrated Intel Arc GPU built into the same chip; there is no discrete GPU option on this chassis, and none is needed for the office, video-conferencing and multi-monitor work this laptop is aimed at.
32GB Soldered Memory, 1TB SSD
32GB of LPDDR5X memory is soldered directly to the board, which is how ASUS keeps this chassis under a kilogram — but it does mean the 32GB is fixed for the machine's lifetime, with no SO-DIMM upgrade path later. Storage is a 1TB M.2 NVMe PCIe 4.0 SSD. Together that is enough headroom for demanding multitasking, a large local Outlook cache, and Office plus line-of-business applications running side by side without the machine running short.
Thunderbolt 4 and Wi-Fi 7, No Built-In Ethernet
Ports are 2 x Thunderbolt 4 (also used for charging), 2 x USB 3.2 Gen 2 Type-A, 1 x HDMI 2.1 and a 3.5mm audio jack, with Wi-Fi 7 and Bluetooth handling wireless. There is no RJ45 Ethernet port built into this chassis, which is standard for a laptop this thin — if your office runs on wired LAN, a USB-C to Ethernet adapter or a Thunderbolt dock closes that gap, and we can supply one alongside the laptop.
Same Spec, Two Finishes, Two Price Tiers
This configuration — TH0910X, part number 90NX09J2-M010D0 — sits in ASUS's higher B9406 price tier, matched in every specification except colour by our Morn Grey listing, B9406CAA-TH0868X. A step down in price, we also carry the identical Core Ultra 7-356H / 32GB / 1TB configuration under part numbers TG0939X (Jet Fog) and TG0624W (Morn Grey); ASUS's own configurator prices the TH pair above the TG pair without publishing a spec sheet reason beyond finish and price band, so if the exact difference matters to your purchasing decision, email us and we will check the current ASUS Singapore pricing structure with you before you order.

SourceIT supplies the ASUS ExpertBook Ultra B9406CAA-TH0910X with a full GST invoice and local Singapore support. ASUS backs this model with a 3-year international warranty including local carry-in and onsite service in Singapore, so most hardware issues are resolved locally rather than by shipping the unit overseas.

Connectivity & Setup / Security Features
Dock or Charge Through Either Thunderbolt Port
Both Thunderbolt 4 ports support DisplayPort output, 40 Gbps data transfer and charging, so a single-cable Thunderbolt dock on a desk can power the laptop, drive an external monitor and connect peripherals through one port, leaving the other free. The USB 3.2 Gen 2 Type-A ports and HDMI 2.1 output handle a direct monitor connection, mice and USB drives without a dock.
Working Around the Missing Ethernet Port
This chassis has no built-in RJ45 port, unlike the ExpertBook B3, B5 and P3 ranges we also carry. A USB-C to Gigabit Ethernet adapter or a Thunderbolt dock with an Ethernet port is the straightforward fix for offices that still need a wired connection — ask us to bundle one with your order if that applies to this laptop's users.
Wi-Fi 7 for Busy Office Networks
Wi-Fi 7 supports higher throughput and lower latency than Wi-Fi 6E on a compatible access point, which shows up most on a busy office floor with many devices competing for airtime. The Intel AI Boost NPU handles supported on-device AI features locally — Windows Studio Effects for video calls and local AI acceleration in Copilot-enabled Microsoft 365 apps — without sending that processing to the cloud or loading down the CPU cores.
Sign-In and Data Protection
The IR-equipped webcam supports Windows Hello facial recognition for fast sign-in, and a TPM 2.0 chip holds BitLocker recovery keys in hardware — the baseline most Singapore corporate IT policies require before a device is trusted with company data. The physical camera shutter is a mechanical cover, not a software toggle, so the lens is blocked regardless of what any app requests.

Frequently Asked Questions — ASUS B9406CAA-TH0910X
How does this differ from the Morn Grey B9406CAA-TH0868X?
Only in colour. Processor, memory, storage and display are identical — this is the Jet Fog finish of the same Core Ultra 7-356H / 32GB / 1TB configuration.
Why does this cost more than the TG0939X, which is also Jet Fog?
Both use the same Core Ultra 7-356H processor, 32GB memory, 1TB SSD and display. ASUS prices the TH-prefix pair (this listing and TH0868X) above the TG-prefix pair (TG0939X and TG0624W) in its own configurator without publishing a further spec sheet difference beyond finish and price band. Email us if you would like that checked against current ASUS Singapore pricing before ordering.
Can I add more memory or a bigger drive later?
No — the 32GB LPDDR5X memory is soldered to the board on this chassis, so the configuration is fixed at the point of order. There is no user-accessible SO-DIMM slot to expand it later.
Is there a wired network port?
No RJ45 Ethernet port is fitted. A USB-C to Ethernet adapter or a Thunderbolt dock with an Ethernet port is the standard fix — ask us to include one if your office needs wired LAN for this laptop.
What is Tandem OLED, and is it worth the price over a standard panel?
It is a two-layer OLED construction that gives a meaningfully higher sustained (typical) brightness than a conventional single-layer OLED panel while keeping OLED's contrast and colour accuracy — genuinely useful in a bright Singapore office where a dimmer OLED panel would wash out under overhead lighting or near a window.
Does this laptop have a discrete GPU?
No. Graphics run on the integrated Intel Arc GPU built into the Core Ultra 7-356H processor — sufficient for office, video-conferencing and multi-monitor work, but not intended for gaming or GPU-accelerated rendering.
What does the NPU actually do for an everyday business user?
It runs supported on-device AI features locally — Windows Studio Effects for video calls and local AI acceleration in Copilot-enabled Microsoft 365 apps — rather than routing that processing through the CPU or the cloud.
How does the weight compare to the rest of your ExpertBook range?
At under 1 kg starting weight, this is noticeably lighter than the ExpertBook P3, P5 or B-series laptops we carry, while still holding a 70Whrs battery — a genuinely strong combination for staff who carry the laptop between meetings or sites throughout the day.
Does it come with a Singapore warranty and a GST invoice?
Yes. Every ASUS ExpertBook Ultra B9406CAA-TH0910X 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.
