ASUS ROG NUC U9/1TB/32GB/RTX4070/WIN11 NUC14SRKU9BYAR0
PRODUCT DESCRIPTION
ASUS ROG NUC U9 Core Ultra 9 185H / RTX 4070 / 32GB / 1TB SSD / Win 11 (NUC14SRKU9BYAR0) - 3 Years Local Warranty
A 2.5-Litre RTX 4070 Mini Gaming PC for Singapore Desks
The ASUS ROG NUC U9 NUC14SRKU9BYAR0 packs an Intel Core Ultra 9 185H processor and an NVIDIA GeForce RTX 4070 Laptop GPU into a 2.5-litre chassis — small enough for a desk that has no room for a full ATX tower, with genuine 1440p-class gaming performance rather than the compromises of an integrated-graphics mini PC. This is a complete system: 32 GB of DDR5 memory and a 1 TB NVMe SSD are fitted, Windows 11 is pre-installed, and a vertical stand is in the box for either orientation.
NVIDIA GeForce RTX 4070 Laptop GPU — Ray Tracing and DLSS in a Mini Chassis
Graphics come from an NVIDIA GeForce RTX 4070 Laptop GPU with 8 GB of GDDR6 memory, running at 115 W with up to 25 W of NVIDIA Dynamic Boost available. As a laptop-class GPU rather than a full desktop RTX 4070, expect performance closer to a high-end gaming laptop than a discrete desktop card of the same name — still comfortably capable of 1440p gaming with ray tracing and DLSS enabled, in a fraction of the space a desktop RTX 4070 tower would need.
Intel Core Ultra 9 185H — 16 Cores, Hybrid Architecture
The Core Ultra 9 185H is a 16-core, 22-thread hybrid processor with 24 MB of cache and a maximum turbo of 5.1 GHz, with an Intel AI Boost NPU integrated alongside the CPU cores. It handles the mixed load a gaming mini PC actually sees well — background chat and streaming software alongside the game itself, encoding for recording or streaming, and everyday multitasking outside of gaming sessions.
32 GB DDR5 SO-DIMM, Storage Expansion for Later
Memory ships as 32 GB of DDR5-5600 across two SO-DIMM modules — conventional removable memory, not soldered, so a future upgrade is a physical module swap rather than a factory-fixed limit. Storage is a 1 TB M.2 NVMe PCIe 4.0 SSD, with the chassis supporting up to three M.2 slots in total for further drives as your game library grows.
Vapor Chamber Cooling, Addressable RGB Panel
ASUS cools the ROG NUC chassis with a vapor chamber and heat pipe thermal design, built to keep the system quiet under a sustained gaming load rather than just a short burst. An addressable backlit ROG panel on the chassis supports Aura Sync RGB lighting and a custom logo design, and the system is Raikiri Pro compatible for wired controller use.
A Genuine Small-Footprint Alternative to a Gaming Tower
At under 2.5 litres, the ROG NUC U9 occupies a fraction of the volume of even a compact ATX gaming tower, while still carrying a discrete NVIDIA GPU with its own dedicated GDDR6 memory rather than relying on shared system RAM the way integrated-graphics mini PCs do. For a Singapore apartment, a shared household desk, or an office that wants a capable gaming or creative rig without committing floor or desk space to a full tower, that combination — real discrete graphics in a genuinely small chassis — is the point of the ROG NUC line.

Connectivity & Setup / Expansion
Cooling and Thermal Design
ASUS cools the ROG NUC chassis with a vapor chamber paired with heat pipes rather than a simpler fan-and-heatsink layout, which is what lets an RTX 4070-class GPU and a 16-core CPU coexist in a 2.5-litre enclosure without excessive noise under sustained load. Both vertical and horizontal orientations are supported, with a vertical stand supplied in the box — vertical orientation generally gives the internal fans a more natural airflow path, worth considering for a long gaming or rendering session.
Memory Upgrade Path
Memory is conventional removable DDR5 SO-DIMM across two slots, not soldered. The as-shipped 32 GB (2 x 16 GB) can be swapped for larger modules if a future workload needs more; ask SourceIT to quote and fit an upgrade.
Storage Upgrade Path
The platform supports up to three M.2 2280 PCIe Gen4 slots in total, against the single 1 TB drive fitted as standard — genuine room to add drives as a game library or capture footage grows, without replacing the primary drive.
Networking and Ports
Wired networking is 2.5 Gigabit Ethernet, with Intel Killer Wi-Fi 6E and Bluetooth 5.3 for wireless. Display output covers Thunderbolt 4 (DisplayPort 2.1), HDMI 2.1 and two DisplayPort 1.4a outputs — enough for a primary gaming display plus a secondary monitor without needing a dock.

Frequently Asked Questions — ASUS ROG NUC U9 NUC14SRKU9BYAR0
Is the RTX 4070 in this the same as a desktop RTX 4070?
No — it is the RTX 4070 Laptop GPU, an 8 GB GDDR6 mobile-class part running at 115 W plus up to 25 W of Dynamic Boost. It performs closer to a high-end gaming laptop than a full desktop RTX 4070 card, which is the trade-off for fitting real ray-tracing performance into a 2.5-litre chassis.
Is this a complete system or a barebone unit?
Complete system. It ships with the Core Ultra 9 185H processor, RTX 4070 Laptop GPU, 32 GB DDR5 memory and a 1 TB NVMe SSD already fitted, with Windows 11 pre-installed.
Can I add more memory or storage later?
Yes to both. Memory uses conventional removable DDR5 SO-DIMM, not soldered, so a larger kit can be fitted later. Storage has room for up to three M.2 2280 PCIe Gen4 drives in total against the one fitted as standard. Ask SourceIT to quote and fit either upgrade.
How loud is it under gaming load?
ASUS's stated design goal for the vapor chamber and heat pipe cooling system is to run quiet under sustained gaming load; we do not have an independently verified dBA figure to quote, so treat this as a design intention rather than a measured spec — ask us if a specific noise figure matters for your environment.
Can I orient it vertically?
Yes, and a vertical stand is included in the box. Both vertical and horizontal placement are supported.
How does this compare with the ROG NUC U7 configuration?
The U7 (NUC14SRKU7AXAR0) uses a Core Ultra 7 155H processor and an RTX 4060 Laptop GPU with 16 GB DDR5 and a 512 GB SSD — a lower-cost configuration in the same chassis. This U9 configuration steps up the CPU, GPU and memory/storage.
Does it support RGB lighting customisation?
Yes. The addressable backlit ROG panel supports ASUS Aura Sync with multiple synchronisation modes for ROG peripherals, and the panel supports a custom logo design.
What networking does it have?
2.5 Gigabit wired Ethernet plus Intel Killer Wi-Fi 6E and Bluetooth 5.3 for wireless.
Is this really discrete graphics, or is it using shared system memory like an integrated GPU?
Genuine discrete graphics. The RTX 4070 Laptop GPU carries its own dedicated 8 GB of GDDR6 memory, separate from the system's 32 GB of DDR5 — it does not borrow from system RAM the way an integrated GPU does, which is the main reason gaming performance here is meaningfully ahead of an integrated-graphics mini PC of similar physical size.
Does it come with a Singapore warranty and a GST invoice?
Yes. Every ASUS ROG NUC U9 NUC14SRKU9BYAR0 sold by SourceIT comes with local Singapore support and a GST invoice; ASUS backs this system with a 3-year warranty.
