ASUS NUC 15 PRO Intel U7-255H/ 16GB/ 512GB/ Win 11 Pro
PRODUCT DESCRIPTION
ASUS NUC 15 Pro Intel Core Ultra 7 255H / 16GB / 512GB / Windows 11 Pro (RNUC15CRHU7073C3) - 3 Years Onsite Warranty
A Complete NUC 15 Pro Business PC With Room for Bigger Files
The ASUS NUC 15 Pro RNUC15CRHU7073C3 is a complete system: the Intel Core Ultra 7 255H processor, 16 GB of DDR5 memory and a 512 GB 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 a 512 GB SSD for buyers who want the extra cores and graphics headroom of the Ultra 7 without paying for 1 TB of storage they may not need.
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.
512 GB NVMe SSD, Tool-Less Upgrade Path
Storage is a 512 GB M.2 NVMe PCIe SSD, half the capacity of our 1 TB RNUC15CRHU7074C3 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 512 GB proves tight. 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 512 GB 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, or order the RNUC15CRHU7074C3 configuration instead if 1 TB from the factory suits you better; 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 RNUC15CRHU7073C3
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 512 GB NVMe SSD already fitted, with Windows 11 Pro pre-installed and ready for first sign-in.
How does this compare with the RNUC15CRHU7074C3 configuration?
Identical processor, memory and connectivity — the only difference is storage. This SKU ships with a 512 GB SSD; RNUC15CRHU7074C3 ships with 1 TB. 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 RNUC15CRHU7073C3 sold by SourceIT comes with local Singapore support and a GST invoice; ASUS backs this system with a 3-year onsite warranty.
