ASUS ExpertCenter PN65 Mini-PC Core Ultra 5 125H/ 16GB/ 512GB SSD Win11 Pro
PRODUCT DESCRIPTION
ASUS ExpertCenter PN65 Mini-PC (PN65-S50099AD) - 3 Years Onsite Warranty
A Sub-1-Litre Desktop Built Around Intel Core Ultra
The ASUS ExpertCenter PN65-S50099AD packs a full Windows 11 Pro desktop into a chassis measuring just 120 x 130 x 58 mm — under one litre of volume and light enough to sit on a desk, hide behind a monitor, or go on a VESA mount at the back of a display. Under the hood is an Intel Core Ultra 5 125H processor with built-in Intel Arc Graphics, paired with 16 GB of DDR5-5600 memory and a 512 GB PCIe 4.0 NVMe SSD. For a Singapore office standardising on a compact, quiet desktop for general productivity, finance, reception or branch-office use, this is a ready-to-deploy unit rather than a barebone kit to build out.
Intel Core Ultra 5 125H with Intel Arc Graphics
The Core Ultra 5 125H combines performance and efficient cores with an on-die NPU and Intel Arc Graphics, giving the PN65 enough graphics headroom to drive multiple displays and handle everyday video and image work without a discrete GPU. The chassis is built around ASUS's self-cleaning fan system, which uses a second, reverse-spinning fan to eject dust through a dedicated vent rather than let it accumulate inside — a genuine advantage over a sealed fanless design in Singapore's humid, dusty office and warehouse environments, since airflow keeps running rather than being throttled by an ever-thicker layer of dust.
16 GB DDR5 and a 512 GB PCIe 4.0 NVMe SSD, With Room to Grow
The unit ships with 16 GB of DDR5-5600 SO-DIMM memory and a 512 GB PCIe 4.0 M.2 NVMe SSD as standard. Two SO-DIMM slots support up to 48 GB total, and ASUS documents a second M.2 slot plus an optional 2.5-inch SATA bay for adding more storage later, so a unit bought lean today can be expanded rather than replaced when a heavier workload comes along. Both the memory and the drive bay are accessed tool-lessly, without needing to remove screws to get inside the chassis.
Quad-Display Output, Wi-Fi 7 and 2.5G LAN
Video output covers two HDMI 2.1 ports, a USB Type-C port carrying DisplayPort 1.4 with Power Delivery, and a configurable rear port that can be set to HDMI, DisplayPort 1.4, VGA, COM or a second 2.5G LAN — enough to run up to four 4K displays at 60 Hz from one small box, which suits a trading desk, a design reviewer's dual-monitor setup, or a digital-signage controller equally well. Networking covers Wi-Fi 7 (or Wi-Fi 6E depending on regional radio configuration) with Bluetooth 5.4, plus a wired 2.5G RJ45 LAN port for a stable, low-latency connection where Wi-Fi is not the preferred option.
Supplied Locally, with GST Invoice and Singapore Onsite Warranty
SourceIT supplies the ASUS ExpertCenter PN65-S50099AD with a full GST invoice and local Singapore support. ASUS backs this model with a 3-year onsite warranty, so a hardware fault is resolved at your premises rather than requiring the unit to be couriered back and forth.

Compatibility & Mounting Options
Display and Video Output Compatibility
The PN65-S50099AD drives up to four displays at once across its two HDMI 2.1 outputs, USB-C DisplayPort 1.4 output and configurable rear port. Ordinary HDMI cables and DisplayPort-over-USB-C cables connect directly with no adapter needed for most modern monitors; older VGA-only screens are supported by switching the configurable rear port to VGA at time of order or via the internal header, so confirm your display mix with us before ordering if VGA is required.
VESA Mount and Desk Placement
A VESA mounting bracket is available as an optional accessory to fix the PN65 to the back of a compatible monitor arm or wall bracket, freeing desk space entirely. Where a VESA mount is not fitted, the unit's small footprint (120 x 130 mm) sits comfortably on a desk or a shelf beside a monitor.
Upgrade Path
Both SO-DIMM slots and the second M.2 slot are accessed without tools, so memory can be increased to 48 GB and a second NVMe drive added later without needing to open the chassis with a screwdriver. This is a genuine advantage over a fully sealed mini-PC design when a department's storage or memory needs grow after initial deployment.

Frequently Asked Questions — ASUS PN65-S50099AD
Is this a barebone unit or a complete, ready-to-use PC?
The PN65-S50099AD is a full system: Intel Core Ultra 5 125H processor, 16 GB DDR5 memory, 512 GB PCIe 4.0 NVMe SSD and Windows 11 Pro preinstalled. Plug in a monitor, keyboard and mouse and it is ready to set up.
How many monitors can it drive?
Up to four 4K displays at 60 Hz, using the two HDMI 2.1 ports, the USB-C port with DisplayPort 1.4, and the configurable rear port set to a second DisplayPort or HDMI output.
Can the memory and storage be upgraded later?
Yes. Two SO-DIMM slots support up to 48 GB of DDR5 in total, and a second M.2 NVMe slot plus an optional 2.5-inch SATA bay are documented by ASUS for adding storage. Both the memory and drive bay are tool-less to access.
Does it need a discrete graphics card for everyday office and multi-monitor use?
No. The Intel Arc Graphics built into the Core Ultra 5 125H handles office productivity, video conferencing and multi-display desktops without an add-in card, which is also why the chassis can stay this small.
Is it VESA-mountable behind a monitor?
Yes, with the optional VESA mount bracket, which is sold separately rather than included in the box.
What is the difference between the PN65 and the AMD-based PN55 or PN54 in your catalogue?
The PN65 runs an Intel Core Ultra 5 processor with Intel Arc Graphics, while the PN55 and PN54 run AMD Ryzen AI processors with Radeon Graphics and an NPU rated for Copilot+ PC workloads. All three share the same compact chassis footprint and Wi-Fi 7/2.5G LAN connectivity class; email us your software and AI-workload requirements and we will help you choose.
How dusty environments does the cooling handle?
ASUS documents a self-cleaning fan system that uses a second, reverse-spinning fan to eject dust through a dedicated vent rather than let it build up inside the chassis — useful in Singapore's humid office and light-industrial environments where dust accumulation is a real factor in mini-PC reliability over time.
Does it come with a Singapore warranty and a GST invoice?
Yes. Every ASUS ExpertCenter PN65-S50099AD sold by SourceIT comes with local Singapore support and a GST invoice; ASUS backs this model with a 3-year onsite warranty.
