ASUS ROG NUC Intel U9-275HX/ RTX5080/ DDR5 32GB/ 1TB SSD/ Win 11 Home
PRODUCT DESCRIPTION
ASUS ROG NUC (2025) (RNUC15JNK9X289A0) - 3 Years Local Warranty
An RTX 5080 Gaming Mini PC for Singapore Desks That Don't Have Room for a Tower
The ASUS ROG NUC (2025) RNUC15JNK9X289A0 pairs a 24-core Intel Core Ultra 9 275HX processor with an NVIDIA GeForce RTX 5080 Laptop GPU carrying 16 GB of GDDR7 — the flagship graphics configuration in this chassis — inside a chassis that measures roughly 282 x 188 x 57 mm and weighs about 3.1 kg. For anyone searching for an RTX 5080 gaming mini PC in Singapore who wants desktop-class frame rates without a full ATX tower on the floor, this is the top configuration in the ROG NUC (2025) line.
32 GB of DDR5-6400 memory and a 1 TB NVMe SSD are fitted as standard, Windows 11 Home is pre-installed, and the system is ready to run out of the box.
NVIDIA GeForce RTX 5080 Laptop GPU — 7,680 CUDA Cores, 1,334 AI TOPS
The RTX 5080 Laptop GPU carries 16 GB of GDDR7 memory and 7,680 CUDA cores on NVIDIA's Blackwell architecture, rated by NVIDIA at 1,334 AI TOPS. NVIDIA's published TGP range for this GPU tier runs up to 175 W; ASUS does not break out the exact figure configured for this chassis on its public specification page. That headroom is enough for native 1440p ultra and demanding 4K work with DLSS 4 and ray tracing enabled, and it is the graphics ceiling of this generation of ROG NUC — the RTX 5070 and RTX 5070 Ti configurations in the same chassis both sit a tier below it.
Intel Core Ultra 9 275HX — 24 Cores, 5.4 GHz Turbo
The Core Ultra 9 275HX is a 24-core, 24-thread hybrid processor (8 Performance + 16 Efficient cores) with 36 MB of Intel Smart Cache and a 5.4 GHz maximum turbo. Core count and thread count are equal on this generation — the Performance cores do not run Hyper-Threading. The integrated Intel AI Boost NPU adds up to 13 TOPS on top of whatever the discrete GPU is doing, which sits below Microsoft's 40 TOPS threshold for Copilot+ PC features.
32 GB DDR5-6400, Dual Channel, with a Second Storage Slot in Reserve
Memory ships as 32 GB across two CSO-DIMM modules running at DDR5-6400, dual channel. Storage is a 1 TB M.2 2280 NVMe PCIe 4.0 SSD, with a second, empty M.2 2280 slot rated for a further PCIe 4.0 or PCIe 5.0 drive from 1 TB up to 4 TB — useful if 1 TB starts to feel tight once a modern game library and a few large creative projects are on the drive at once.
Triple-Fan, Dual Vapor Chamber Cooling with MIL-STD 810H Durability Testing
ASUS cools this chassis with three fans working against a dual vapor chamber, and the ROG NUC (2025) range has passed MIL-STD 810H durability testing — a military-derived standard covering shock, vibration and environmental stress, not a claim about acoustic output. The chassis is designed to stand vertically on the included stand; ASUS notes it can be laid on its side with the stand removed, but recommends checking that the exhaust vents still have clear airflow before doing so.

Connectivity & Setup / Thermal Design
Cooling and Thermal Design
Three fans work against a dual vapor chamber to keep the Core Ultra 9 275HX and RTX 5080 combination running within thermal limits inside a 3-litre chassis. The ROG NUC (2025) range has passed MIL-STD 810H durability testing, which covers shock, vibration, altitude and temperature extremes — it is a build-quality and reliability standard, not a noise rating, and ASUS does not publish a dBA figure for this range that we can verify. Expect the fans to be clearly audible under sustained gaming load in a quiet room; a headset is the practical answer during demanding sessions.
Vertical Placement, with Side-Mounting Possible
The chassis is designed to stand vertically on the removable stand supplied in the box. ASUS's own documentation notes it can technically be laid on its side once the stand is removed, but only if the exhaust vents are left clear to vent properly — this is not the flexible either-orientation design of the newer ROG NUC 16 range, so plan the installation around vertical placement as the default.
Memory and Storage Upgrade Path
32 GB (2 x 16 GB) of DDR5-6400 occupies both CSO-DIMM slots as shipped. ASUS's specification page states a maximum of 96 GB using 48 GB DDR5-5600 SO-DIMM modules — a different memory speed from the DDR5-6400 kit fitted at the factory — so treat that maximum as ASUS's published ceiling rather than a guaranteed same-speed upgrade path, and confirm compatibility with SourceIT before buying replacement modules. The second M.2 2280 slot is empty and tool-less, ready for a further NVMe drive up to 4 TB.
Networking and Display Outputs
Wired networking is 2.5 Gigabit Ethernet over RJ45, with Intel Wi-Fi 7 (BE200) and Bluetooth 5.4 for wireless. Display output is identical across every configuration of this chassis: two HDMI 2.1 FRL, two DisplayPort 2.1 and one Thunderbolt 4 Type-C carrying DisplayPort 2.1, supporting up to four displays at once.

Frequently Asked Questions — ASUS ROG NUC (2025) RNUC15JNK9X289A0
Is the RTX 5080 in this the same as a desktop RTX 5080 card?
No — it is the RTX 5080 Laptop GPU, a 16 GB GDDR7 mobile-class part with 7,680 CUDA cores on NVIDIA's Blackwell architecture and a configurable TGP up to 175 W. It is the fastest GPU configuration available in this chassis, but expect performance closer to a high-end gaming laptop than a full desktop RTX 5080 card in a much larger tower.
Is this a complete system or a barebone unit?
Complete system. It ships with the Core Ultra 9 275HX processor, RTX 5080 Laptop GPU, 32 GB DDR5-6400 memory and a 1 TB NVMe SSD already fitted, with Windows 11 Home pre-installed.
Will this handle 4K gaming?
Yes, with DLSS 4 and ray tracing doing real work at native 4K in the most demanding titles. 16 GB of GDDR7 and 7,680 CUDA cores give this configuration a genuine edge over the RTX 5070 and RTX 5070 Ti builds in the same chassis, and it is the top GPU tier ASUS offers in this range.
Can I add more memory or storage later?
Storage yes — a second M.2 2280 slot is empty and tool-less, rated for a further drive up to 4 TB. Memory is more involved: both CSO-DIMM slots are already occupied by the 32 GB kit, so an upgrade means replacing both modules. ASUS's specification page quotes a maximum of 96 GB using 48 GB DDR5-5600 modules, a different speed from the DDR5-6400 kit fitted as standard — confirm the real upgrade path with SourceIT before buying modules.
Can the chassis lie flat, or does it need to stand vertically?
The chassis is designed to stand vertically on the included removable stand. ASUS states it can technically be laid on its side with the stand removed, but only if the exhaust vents remain unobstructed — this is a narrower placement allowance than the newer ROG NUC 16 range, which supports both orientations without caveats.
What is the difference between this and the RNUC15JNK9X28AA0?
Nothing beyond storage capacity. The RNUC15JNK9X28AA0 carries the identical Core Ultra 9 275HX, RTX 5080, 32 GB DDR5-6400 specification, fitted with a 2 TB SSD from the factory instead of the 1 TB SSD in this listing.
How does this compare with the RTX 5070 and RTX 5070 Ti configurations in the same chassis?
CPU, memory, cooling, ports and chassis are identical across the range — the only difference is the GPU. This configuration steps up from the RTX 5070 Ti's 12 GB GDDR7 and 992 AI TOPS to the RTX 5080's 16 GB and 1,334 AI TOPS, which matters most for native 4K work and larger local AI models.
Does it come with a Singapore warranty and a GST invoice?
Yes. Every ASUS ROG NUC (2025) RNUC15JNK9X289A0 sold by SourceIT comes with local Singapore warranty support and a GST invoice; ASUS backs this system with a 3-year warranty.
