ASUS ROG NUC Intel U9-275HX/ RTX5070Ti/ DDR5 32GB/ 1TB SSD/ Win 11 Home
PRODUCT DESCRIPTION
ASUS ROG NUC (2025) (RNUC15JNK9X389A0) - 3 Years Local Warranty
The Top Configuration in the ROG NUC (2025) Range
The ASUS ROG NUC RNUC15JNK9X389A0 is the highest-tier build in the ROG NUC (2025) line: an Intel Core Ultra 9 275HX processor paired with an NVIDIA GeForce RTX 5070 Ti Laptop GPU carrying 12 GB of GDDR7, in the NUC15JNK platform's vertical-only 3-litre chassis. For an RTX 5070 Ti compact gaming PC on this generation of ROG NUC, this is the configuration to specify.
32 GB of DDR5 memory and a 1 TB NVMe SSD are fitted as standard, Windows 11 Home is pre-installed, and the system arrives complete and ready to run.
NVIDIA GeForce RTX 5070 Ti Laptop GPU — 5,888 CUDA Cores, 992 AI TOPS
The RTX 5070 Ti Laptop GPU carries 12 GB of GDDR7 memory and 5,888 CUDA cores on NVIDIA's Blackwell architecture, with fifth-generation Tensor Cores rated at 992 AI TOPS — the same silicon fitted to the RTX 5070 Ti configuration in the newer ROG NUC 16 range (RNUC16JNK9X389A3). That is enough headroom for 1440p ultra gaming with ray tracing and DLSS 4, and workable for entry 4K.
Intel Core Ultra 9 275HX — 24 Cores, 5.4 GHz Turbo
24 cores (8 Performance + 16 Efficient), 24 threads, 36 MB of Intel Smart Cache and a 5.4 GHz maximum turbo. This is the previous-generation sibling of the Core Ultra 9 290HX Plus used in the newer ROG NUC 16 — the same core configuration and cache size, with the 290HX Plus taking the turbo slightly higher to 5.5 GHz and launching a year later. In practice the two processors are close enough that the GPU tier and chassis generation matter more to your buying decision than the CPU generation alone.
32 GB DDR5, Dual Channel
Memory ships as 32 GB across two DDR5 CSO-DIMM modules in dual channel, matching the memory capacity of the equivalent RTX 5070 Ti configuration in the ROG NUC 16 range. Storage is a 1 TB M.2 2280 NVMe PCIe 4.0 SSD, with a second M.2 2280 slot free and tool-free to access.
Triple-Fan Vapor Chamber Cooling, Vertical-Only Chassis
ASUS cools this range with a triple-fan, dual vapor chamber design and Aura Sync ARGB lighting. This chassis is vertical-only with an integrated base — the newer ROG NUC 16 adds a removable stand supporting horizontal placement as well, which is the clearest physical difference between the two generations at this GPU tier.
Supplied Locally, with GST Invoice and Singapore Warranty
SourceIT supplies the ROG NUC RNUC15JNK9X389A0 with a full GST invoice and local Singapore warranty support, backed by ASUS's 3-year warranty term for this range.
Considering the newer chassis with the same GPU tier? The ASUS ROG NUC 16 RNUC16JNK9X389A3 pairs the identical RTX 5070 Ti with the newer Core Ultra 9 290HX Plus and dual-orientation placement. Email sales@sourceit.com.sg and we will help you compare both generations.

Connectivity & Setup / Thermal Design
Cooling and Thermal Design
The RTX 5070 Ti configuration uses the same triple-fan, dual vapor chamber thermal design as the rest of the ROG NUC (2025) range, here working against the highest total GPU power draw in the line. ASUS does not publish a specific dBA figure for this range on its public specification pages, so we do not print one here — ask us if a measured noise figure matters for your environment.
Vertical-Only Chassis
An integrated base supports vertical orientation only. The newer ROG NUC 16 range adds a removable stand supporting both vertical and horizontal placement, which is worth factoring in if flexible placement matters more to you than the CPU generation.
Memory and Storage Upgrade Path
32 GB of DDR5 occupies both CSO-DIMM slots as shipped. ASUS's specification page for this range states a maximum capacity of 96 GB, expressed as 48 GB DDR5-5600 SO-DIMM x2 — a different module type and speed from the DDR5-6400 CSO-DIMM fitted as standard, so confirm compatibility with SourceIT before ordering an upgrade kit. A second M.2 2280 slot is free for storage expansion, supporting drives up to 4 TB.
Networking and Display Outputs
Wired networking is 2.5 Gigabit Ethernet, with Intel Wi-Fi 7 (BE200) and Bluetooth 5.4 for wireless. Display output covers Thunderbolt 4 Type-C, two HDMI 2.1 and two DisplayPort 2.1 outputs, with six USB ports on this chassis running at 10 Gbps.

Frequently Asked Questions — ASUS ROG NUC RNUC15JNK9X389A0
Is the RTX 5070 Ti in this the same silicon as the RTX 5070 Ti in the newer ROG NUC 16?
Yes — both use the same NVIDIA RTX 5070 Ti Laptop GPU with 12 GB of GDDR7 and 5,888 CUDA cores. The difference between this SKU and the ROG NUC 16 equivalent (RNUC16JNK9X389A3) is the CPU generation and the chassis, not the GPU.
Is this a complete system?
Yes. It ships with the Core Ultra 9 275HX processor, RTX 5070 Ti Laptop GPU, 32 GB DDR5 memory and a 1 TB NVMe SSD fitted, with Windows 11 Home pre-installed.
How much does the CPU generation actually matter — 275HX vs 290HX Plus?
Both are 24-core, 24-thread hybrid processors with 36 MB of cache; the 290HX Plus takes maximum turbo to 5.5 GHz against the 275HX's 5.4 GHz. It is a small gap. The bigger practical differences between this SKU and its ROG NUC 16 equivalent are chassis orientation flexibility and colour choice, not raw CPU performance.
Can I lay it flat, or only stand it up?
Vertical only. This chassis uses an integrated base; the removable dual-orientation stand is a feature specific to the newer ROG NUC 16.
Can I add more memory or storage later?
Storage yes, via the tool-free second M.2 2280 slot. Memory is possible, but ASUS's published maximum (96 GB, expressed as 48 GB DDR5-5600 SO-DIMM x2) uses a different module type from the DDR5-6400 CSO-DIMM fitted as standard — confirm compatibility with SourceIT first.
Will this handle 4K gaming?
At entry level, yes, with ray tracing and DLSS 4 doing real work to get there. For demanding native 4K at maximum settings, the RTX 5080 configuration in the newer ROG NUC 16 range is the better fit — this range's top GPU tier is the RTX 5070 Ti.
Should I buy this or wait for ROG NUC 16 stock?
Both are current, fully supported ASUS systems with the same 3-year warranty term. If horizontal placement or a white chassis option matters to you, the ROG NUC 16 is the newer platform; if you need stock immediately, ask SourceIT which range has the shorter lead time right now.
Does it come with a Singapore warranty and a GST invoice?
Yes. Every ASUS ROG NUC RNUC15JNK9X389A0 sold by SourceIT comes with local Singapore warranty support and a GST invoice; ASUS backs this system with a 3-year warranty.
