PRODUCT DESCRIPTION

ASUS ROG NUC 16 Intel Core Ultra 9 Processor 290HX Plus / RTX 5070 Ti / 32GB DDR5-6400 / 1TB / Windows 11 Home (RNUC16JNK9X389A3) - 3 Years Onsite Local Warranty

Core Ultra 9 and RTX 5070 Ti in a 3-Litre ROG Chassis

The ASUS ROG NUC 16 RNUC16JNK9X389A3 combines the Intel Core Ultra 9 Processor 290HX Plus with an NVIDIA GeForce RTX 5070 Ti Laptop GPU in Obsidian Black. It sits between the RTX 5060 entry build and the RTX 5080 flagship, and for many gamers and creators it is the balanced choice in the range.

NVIDIA GeForce RTX 5070 Ti Laptop GPU — 12 GB GDDR7

The RTX 5070 Ti Laptop GPU brings 12 GB of GDDR7 and NVIDIA's Blackwell architecture, with fifth-generation Tensor Cores driving DLSS 4.5 and Dynamic Multi Frame Generation in supported games. It is a strong match for high-refresh 1440p gaming and capable 4K play, as well as GPU-accelerated video editing, rendering and local AI tools.

Intel Core Ultra 9 290HX Plus with 32 GB DDR5-6400

It shares the Core Ultra 9 290HX Plus with the RTX 5080 configuration — a 24-thread processor with a 55 W base TDP, configurable from 45 W to 160 W — together with 32 GB of DDR5-6400 across two CSO-DIMM modules and a 1 TB M.2 NVMe PCIe 4.0 SSD. Windows 11 Home is pre-installed.

Built Around a 3-Litre Gaming Chassis

Every configuration in the ROG NUC 16 family shares the same compact chassis footprint — 282.5 x 189.5 x 56.5 mm and 3.2 kg — with a patented removable stand so the system can stand upright beside a monitor or lie flat under one. A built-in G-sensor detects the orientation and adjusts the thermal settings to suit. Lighting is controlled through Armoury Crate with Aura Sync, and ASUS states the design has passed MIL-STD-810H testing along with additional bump and drop tests.

Cooling Designed for Desktop-Class Graphics

QuietFlow Cooling uses three 102 x 102 x 17 mm fans and a vapor chamber with 72% thermal coverage, including full contact over the CPU and the laptop GPU. ASUS rates the design at a 12% increase in CPU thermal capacity and below 38 dB(A) under sustained high load. A dedicated SSD heatsink brings SSD operating temperature down to 59°C, an 18.5% reduction in thermal output compared with running without it.

Up to Five 4K Displays

Rear outputs comprise two HDMI 2.1 FRL ports, two DisplayPort 2.1 ports and a Thunderbolt 4 Type-C port with DisplayPort 2.1, so the system can drive up to five 4K displays. HDMI 2.1 supports 4K at 120 Hz or 8K at 60 Hz with HDR10+ and eARC, and ASUS lists 8K at 60 Hz over DisplayPort 2.1 (UHBR20) across two monitors. Six 10 Gbps USB Type-A ports, a 20 Gbps USB Type-C port, Intel Killer Wi-Fi 7, Bluetooth 5.4 and 2.5 Gigabit Ethernet cover everything else.

Supplied Locally, with GST Invoice and Singapore Onsite Warranty

SourceIT supplies the ASUS ROG NUC 16 RNUC16JNK9X389A3 with a full GST invoice and local Singapore support. ASUS backs this system with a 3-year onsite warranty, so a qualifying hardware fault is attended to at your premises.

Prefer a white chassis? The RNUC16JNK9X389A3 - White carries the same specification in Moonlight White. Email sales@sourceit.com.sg and we will confirm stock for either colour.

Connectivity & Setup / Expansion

Setting Up

Connect a monitor to any of the HDMI 2.1, DisplayPort 2.1 or Thunderbolt 4 outputs, plug in a keyboard and mouse, and connect the 380 W external adapter to the rear DC input. Windows 11 Home is pre-installed, so the system is ready for first sign-in. Armoury Crate handles hardware monitoring, cooling profiles, lighting and driver updates, and the NVIDIA App keeps Game Ready and Studio drivers current.

Vertical or Horizontal Placement

The removable stand supports upright placement beside a display or flat placement under a monitor or in an AV cabinet. The G-sensor detects which way the system is sitting and adjusts thermal behaviour accordingly, so either orientation is a supported configuration.

Memory and Storage Upgrades

Memory and the SSD are reached without tools. Both memory slots are populated with 2 x 16 GB DDR5-6400 CSO-DIMM as shipped; ASUS lists a maximum of 64 GB (DDR5-6400 CSO-DIMM x2 or DDR5-5600 SO-DIMM x2), so moving to 64 GB means replacing both modules. The board has two M.2 2280 NVMe slots — one PCIe Gen4 x4 and one PCIe Gen5 x4 — each supporting 1 TB to 2 TB drives, so there is room to add a second SSD as a game or project library grows.

Networking

Wired networking is 2.5 Gigabit Ethernet on a Realtek RTL8125D controller. Wireless is Intel Killer Wi-Fi 7 BE1750x with support for 320 MHz channels, plus Bluetooth 5.4 for controllers, headsets and peripherals.

ASUS Ecosystem Features

ASUS Power Sync powers the NUC and a compatible monitor on and off together over HDMI CEC, and GlideX lets you share and control screens across devices. Aura Sync links the system lighting with other compatible ASUS and ROG gear.

Frequently Asked Questions — ASUS ROG NUC 16 RNUC16JNK9X389A3

Is this a complete system?

Yes. It ships with the Intel Core Ultra 9 Processor 290HX Plus, NVIDIA GeForce RTX 5070 Ti Laptop GPU, 32GB DDR5-6400 memory and a 1TB NVMe SSD fitted, with Windows 11 Home pre-installed.

How does the RTX 5070 Ti compare with the RTX 5080 configuration?

The processor, memory and SSD are the same. The RTX 5080 Laptop GPU adds more graphics performance and 16 GB of GDDR7 against 12 GB here; the RTX 5070 Ti configuration is the better value where 12 GB is enough for your games and applications.

Can I upgrade memory and storage later?

Yes, without tools. Memory is fitted as 2 x 16 GB, so a move to the 64 GB maximum means replacing both modules. A second M.2 2280 slot is available for an additional 1 TB–2 TB NVMe SSD.

Is there a white version?

Yes — the RNUC16JNK9X389A3 - White (90AS00S2-M00350) has the identical specification in Moonlight White.

Can it lie flat as well as stand upright?

Yes. The patented removable stand supports both vertical and horizontal placement, and the built-in G-sensor adjusts thermal settings to the orientation.

How many monitors can it drive?

Up to five 4K displays across the two HDMI 2.1 FRL, two DisplayPort 2.1 and one Thunderbolt 4 (DisplayPort 2.1) outputs. HDMI 2.1 also supports 8K at 60 Hz.

Does it have Wi-Fi 7?

Yes — Intel Killer Wi-Fi 7 BE1750x with Bluetooth 5.4, alongside 2.5 Gigabit Ethernet.

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

Yes. Every ASUS ROG NUC 16 RNUC16JNK9X389A3 sold by SourceIT comes with local Singapore support and a GST invoice; ASUS backs this system with a 3-year onsite warranty.
