ASUS NUC 15 PRO Intel U7-255H/ 16GB/ 1TB/ Win 11 Pro
PRODUCT DESCRIPTION
ASUS NUC 15 Pro Intel Core Ultra 7 255H / 16GB / 1TB / Windows 11 Pro (RNUC15CRHU7074C3) - 3 Years Onsite Warranty
A Complete NUC 15 Pro Business PC With Room for Bigger Files
The ASUS NUC 15 Pro RNUC15CRHU7074C3 is a complete system: the Intel Core Ultra 7 255H processor, 16 GB of DDR5 memory and a 1 TB NVMe SSD are already fitted, with Windows 11 Pro pre-installed and activated. Connect a monitor, keyboard and mouse and it is ready to work — there is no barebone assembly step. The Core Ultra 7 255H is the higher CPU tier in the NUC 15 Pro Core Ultra range, and this configuration pairs it with 1 TB of storage for buyers working with larger datasets, virtual machine images or media libraries who do not want to plan a storage upgrade on day one.
Intel Core Ultra 7 255H — 16 Cores, Arc 140T Graphics, 13 TOPS NPU
The Core Ultra 7 Processor 255H pairs 6 performance cores, 8 efficient cores and 2 low-power efficient cores for 16 cores and 16 threads in total — more cores and threads than the Core Ultra 5 225H's 14/14. Max turbo is 5.1 GHz, backed by 24 MB of Intel Smart Cache (up from 18 MB on the Ultra 5), with a 28 W base power and 115 W maximum turbo power. Graphics step up too: the Intel Arc 140T GPU carries 8 Xe-cores, one more than the Ultra 5's Arc 130T, running at a higher maximum clock, with hardware ray tracing, XeSS upscaling and AV1 encode/decode. The on-chip Intel AI Boost NPU is rated at 13 peak TOPS (INT8) — the same NPU figure as the Ultra 5, so like that configuration this system sits below the 40 TOPS threshold Microsoft requires for Copilot+ PC certification, even though the CPU and GPU are stronger.
16 GB DDR5 as a Single Module — Add the Second Stick for Dual-Channel
Memory ships as 16 GB DDR5 fitted as a single SO-DIMM (16 GB x 1), leaving the second of the two SO-DIMM slots free and the system running single-channel. As with the Core Ultra 5 configurations in this range, that matters more here than on a machine with weaker graphics, because the Arc 140T GPU draws all of its bandwidth from system memory. A matched second 16 GB module enables dual-channel and typically improves graphics-bound work — multi-display use, video, light 3D and the GPU-accelerated share of AI workloads. Both slots are tool-less to access; ask SourceIT to quote a second module and we will fit it before delivery. The platform supports up to 96 GB total across the two slots if more capacity is needed.
1 TB NVMe SSD, Tool-Less Upgrade Path
Storage is a 1 TB M.2 NVMe PCIe SSD — double the capacity of our 512 GB RNUC15CRHU7073C3 configuration on the same processor — accessed through the same tool-less chassis as the memory, so a larger drive can be fitted later without a screwdriver if 1 TB is eventually outgrown. A second M.2 slot is present on the platform for further expansion.
Dual Thunderbolt 4, Dual HDMI 2.1, Four 4K Displays
Two Thunderbolt 4 Type-C ports (DisplayPort 2.1 capable) and two HDMI 2.1 ports support up to four simultaneous 4K displays. Wired networking is a single Intel I226-V 2.5 Gigabit Ethernet port, with Intel Wi-Fi 7 and Bluetooth 5.4 for wireless. The chassis is tool-less with hinged lever-action access for memory and storage, MIL-STD-810H certified, and includes a Kensington lock slot and Intel Platform Trust Technology against unauthorised BIOS modification. A VESA mounting bracket is included for behind-the-monitor placement.

Connectivity & Setup / Expansion
Why the Second Memory Module Matters Here
This configuration ships as a single 16 GB DDR5 module, running single-channel with one SO-DIMM slot free. Because the Intel Arc 140T GPU draws all of its bandwidth from system memory, single-channel operation limits graphics-bound performance — multi-display use, video playback and encode, light 3D, and the GPU-accelerated portion of AI workloads all benefit from dual-channel. A matched second 16 GB module is inexpensive and SourceIT can fit it before delivery if you would rather not open the chassis yourself.
Storage Upgrade Path
The 1 TB primary SSD is accessed through the same tool-less, hinged chassis as the memory. A second M.2 slot is present on the platform for a further drive if 1 TB alone is not enough; ask SourceIT to supply and fit an additional drive before delivery if you would rather receive it ready to go.
Display and Networking Setup
Two Thunderbolt 4 Type-C ports carrying DisplayPort 2.1 plus two HDMI 2.1 outputs support up to four 4K displays between them. Wired networking is a single Intel I226-V 2.5 Gigabit port; if a resilient second wired connection is required for a firewall or gateway role, this chassis only has the one port and we can advise on an alternative.
Copilot+ and On-Device AI
The 13 TOPS NPU gives real hardware acceleration for background AI features and local inference, but it does not meet Microsoft's 40 TOPS Copilot+ PC threshold — the same NPU figure as the Core Ultra 5 configurations in this range, despite the stronger CPU and GPU here. Cloud-based Copilot works normally regardless; on-device Copilot+ experiences such as Recall do not run on this NPU.

Frequently Asked Questions — ASUS NUC 15 Pro RNUC15CRHU7074C3
Is this a complete system or a barebone unit?
Complete system. It ships with the Intel Core Ultra 7 255H processor, 16 GB DDR5 memory and a 1 TB NVMe SSD already fitted, with Windows 11 Pro pre-installed and ready for first sign-in.
How does this compare with the RNUC15CRHU7073C3 configuration?
Identical processor, memory and connectivity — the only difference is storage. This SKU ships with a 1 TB SSD; RNUC15CRHU7073C3 ships with 512 GB. Choose based on how much local storage your workload needs.
Should I add a second memory module?
Yes, if graphics-bound performance matters to you. It ships with a single 16 GB stick running single-channel, and the Arc 140T GPU draws all its bandwidth from system memory — single-channel is the main thing holding this configuration back for anything visual. A matched second module is inexpensive and SourceIT can fit it before delivery.
Is this a Copilot+ PC?
No. The NPU is rated at 13 peak TOPS against Microsoft's 40 TOPS requirement, the same figure as the Core Ultra 5 configurations in this range despite the stronger CPU and GPU here.
How does the Core Ultra 7 255H compare with the Core Ultra 5 225H?
More cores and threads (16/16 versus 14/14), more cache (24 MB versus 18 MB), a higher turbo clock (5.1 GHz versus 4.9 GHz) and a stronger GPU (Arc 140T with 8 Xe-cores versus Arc 130T with 7 Xe-cores). The NPU is identical at 13 TOPS on both.
How many monitors can it drive?
Up to four 4K displays, across two Thunderbolt 4 ports with DisplayPort 2.1 and two HDMI 2.1 outputs.
Can I get dual Ethernet?
Not on this chassis — it has one Intel I226-V 2.5 Gigabit port. If dual LAN is essential for a firewall or gateway role, email us and we will suggest an alternative.
Can I upgrade the storage further?
Yes, through the same tool-less access as the memory, and a second M.2 slot is present for an additional drive. Ask SourceIT to supply and fit it before delivery if you would rather not open the chassis.
Does it come with a Singapore warranty and a GST invoice?
Yes. Every ASUS NUC 15 Pro RNUC15CRHU7074C3 sold by SourceIT comes with local Singapore support and a GST invoice; ASUS backs this system with a 3-year onsite warranty.
