ASUS NUC 16 PRO Intel Ultra 5 325/ 16GB/ 512 SSD/ Win 11 Pro
PRODUCT DESCRIPTION
ASUS NUC 16 Pro Intel Core Ultra 5 325 / 16GB / 512GB SSD / Windows 11 Pro (RNUC16GDKU5663N3) - 3 Years Onsite Local Warranty
An Entry Point Into the NUC 16 Pro Business PC Range
The ASUS NUC 16 PRO RNUC16GDKU5663N3 is a complete Windows 11 Pro system built around the Intel Core Ultra 5 325 processor, with 16 GB of DDR5 memory and a 512 GB NVMe SSD already fitted. As with every full-system NUC 16 Pro SourceIT sells, it arrives ready to sign in — connect a monitor, keyboard and mouse and it is working. For a Singapore office deploying a fleet of compact desktops, front-desk terminals or a lightly-loaded workstation, this is the value tier of the range: a genuine Intel Core Ultra machine, at the lowest entry cost in the NUC 16 Pro line-up.
Intel Core Ultra 5 325 — the SO-DIMM Tier, Not the Soldered "X" Tier
It is worth being precise about which NUC 16 Pro this is. ASUS sells the NUC 16 Pro across two distinct silicon tiers: a Core Ultra 5 / Core Ultra 7 tier built on removable DDR5 SO-DIMM memory (this model), and a separate Core Ultra X7 / Core Ultra X9 tier built on Intel's newer Panther Lake platform with memory soldered directly to the board as LPDDR5x. The Core Ultra 5 325 here is a 6-core, 6-thread processor (2 Performance-cores, 4 Efficient-cores) with Intel Graphics and an integrated NPU, running on the earlier of the two platforms. It is a genuinely capable business processor for office productivity, browser-heavy work and everyday multitasking, but if raw single-thread speed, integrated graphics headroom or the newer Arc B390 GPU matters to your workload, the Core Ultra X7 358H and Core Ultra X9 388H configurations in our catalogue are the ones to look at instead — see the ordering table below.
16 GB DDR5 in Removable SO-DIMM Slots
Memory ships as 16 GB DDR5, fitted across the system's two SO-DIMM slots, both of which are tool-less to access. Because this tier uses conventional removable SO-DIMM memory rather than the soldered LPDDR5x of the X7/X9 tier, a module swap or capacity upgrade is a straightforward physical job rather than something fixed at the factory — ask SourceIT to quote a larger kit and we will fit it before delivery.
512 GB NVMe SSD, Room to Grow
Storage is a 512 GB M.2 NVMe PCIe SSD. The chassis supports additional M.2 storage for buyers who expect to outgrow 512 GB; ask us about fitting a second drive before delivery if you would rather receive it ready to go rather than opening the chassis yourself later.
Dual Thunderbolt 4, Dual HDMI 2.1, Dual 2.5G LAN
Display output is two Thunderbolt 4 Type-C ports (DisplayPort 2.1 capable) plus two HDMI 2.1 ports. Wired networking is dual Intel I226-V 2.5 Gigabit Ethernet — two ports, not one, which is useful where a small office wants a failover WAN link or a machine doing double duty as a lightweight gateway. Wireless is Intel Wi-Fi 7 with Bluetooth 6.0. The chassis measures a compact 144 x 117 x 42 mm.
Deploying a Fleet? What Stays the Same Across the Range
Every full-system NUC 16 Pro SourceIT sells — whether this Core Ultra 5 entry configuration or the Panther Lake X9 flagship — shares the same 144 x 117 x 42 mm chassis footprint, the same tool-less access design, and the same VESA-mountable form factor for behind-the-monitor placement. For a Singapore office standardising imaging, driver packages and physical mounting across a fleet of desks, that consistency matters more than it sounds: a procurement decision to mix Core Ultra 5 and Core Ultra 7 units on this SO-DIMM tier does not complicate desk fit-out or mounting hardware, even though the internal silicon differs.
Supplied Locally, with GST Invoice and Singapore Onsite Warranty
SourceIT supplies the ASUS NUC 16 PRO RNUC16GDKU5663N3 with a full GST invoice and local Singapore support. ASUS backs this system with a 3-year onsite warranty, so a qualifying hardware fault is resolved at your premises rather than a courier round trip.
Need more single-thread or graphics performance than the Core Ultra 5 325 offers? Our ASUS NUC 16 PRO RNUC16GDKU7664N3 is the identical form factor with a Core Ultra 7 356H processor instead. Email sales@sourceit.com.sg and we will help you match the configuration to your workload.

Connectivity & Setup / Expansion
Which NUC 16 Pro Tier Is This?
ASUS splits the NUC 16 Pro line across two platforms. This SKU and its Core Ultra 7 356H sibling are the earlier-platform, SO-DIMM DDR5 tier — conventional removable memory, Intel Graphics rather than Arc, and no Panther Lake NPU headline figure. The Core Ultra X7 358H and Core Ultra X9 388H configurations in our catalogue are the newer Panther Lake tier, with soldered LPDDR5x memory and an Intel Arc B390 GPU. Both tiers share the NUC 16 Pro chassis and warranty terms, but they are genuinely different platforms — check which one your workload needs before ordering.
Memory Upgrade Path
Both SO-DIMM slots are tool-less to reach, so a capacity upgrade is a physical module swap rather than a factory-fixed limit. Send us the capacity you need and we will quote and fit it before delivery.
Storage Upgrade Path
The 512 GB primary SSD sits in a tool-less M.2 bay, and the chassis supports additional M.2 storage. Ask SourceIT to supply and fit a larger or second drive before delivery if you would rather not open the chassis later.
Dual 2.5G LAN and Networking Setup
Two Intel I226-V 2.5 Gigabit Ethernet ports are fitted as standard on this range — useful for a failover WAN connection, a segregated management link, or a lightweight two-port gateway role, none of which the single-LAN NUC 15 Pro chassis can do. Wireless is Intel Wi-Fi 7 with Bluetooth 6.0 for everything else.

Frequently Asked Questions — ASUS NUC 16 PRO RNUC16GDKU5663N3
Is this a complete system or a barebone unit?
Complete system. It ships with the Intel Core Ultra 5 325 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.
Is this the same memory platform as the "X7" and "X9" NUC 16 Pro models?
No. This Core Ultra 5 configuration uses conventional removable DDR5 SO-DIMM memory. The Core Ultra X7 358H and Core Ultra X9 388H configurations in our catalogue are a different, newer Panther Lake platform with memory soldered to the board as LPDDR5x and an Intel Arc B390 GPU. They are not interchangeable memory-upgrade-wise, and the CPU/GPU capability differs substantially — ask us which fits your workload.
Can I add more memory later?
Yes. Both SO-DIMM slots are tool-less to access, so a capacity upgrade is a straightforward module swap rather than a factory-fixed limit. Send us the capacity you need and we will quote and fit it before delivery.
Can I upgrade the storage further?
Yes. The chassis supports additional M.2 storage alongside the 512 GB primary drive. Ask SourceIT to supply and fit it before delivery if you would rather receive it ready to go.
How does this compare with the Core Ultra 7 356H configuration?
Same chassis, memory tier and connectivity — the difference is the processor. The Core Ultra 7 356H configuration (RNUC16GDKU7664N3) offers more cores and higher performance for the same 16 GB / 512 GB footprint. Choose based on how CPU-bound your workload is.
Does it have dual LAN?
Yes — two Intel I226-V 2.5 Gigabit Ethernet ports are standard on this range, which is useful for a failover link or a lightweight gateway role.
How many monitors can it drive?
Four displays across two Thunderbolt 4 (DisplayPort 2.1) ports and two HDMI 2.1 ports.
Is this a Copilot+ certified PC?
ASUS does not publish a Copilot+ PC certification for this Core Ultra 5 configuration. Cloud-based Microsoft Copilot works normally through the browser regardless.
Is the chassis the same across the whole NUC 16 Pro range?
Yes. Every full-system NUC 16 Pro configuration SourceIT sells, on either memory tier, shares the same 144 x 117 x 42 mm footprint and VESA-mountable design, which simplifies desk fit-out and mounting when standardising a fleet across a mix of processor tiers.
Does it come with a Singapore warranty and a GST invoice?
Yes. Every ASUS NUC 16 PRO RNUC16GDKU5663N3 sold by SourceIT comes with local Singapore support and a GST invoice; ASUS backs this system with a 3-year onsite warranty.
