ASUS ExpertCenter PN55-S70020NL Ryzen AI 7 445/ 32GB/ 1TB SSD/ Win 11 Pro
PRODUCT DESCRIPTION
ASUS ExpertCenter PN55 Mini-PC (PN55-S70020NL) - 3 Years Onsite Warranty
The Mid-Tier Ryzen AI 7 Build of the PN55 Chassis
The ASUS ExpertCenter PN55-S70020NL is the AMD Ryzen AI 7 445 configuration of the PN55 Mini-PC, built into the same 130 x 130 x 34 mm chassis used across the whole PN55 range. It ships as a complete system with 32 GB of DDR5-5600 memory and a 1 TB PCIe 4.0 NVMe SSD already fitted and Windows 11 Pro preinstalled, so it goes straight from unboxing to sign-in without any component fitting on your side. For an office or branch desktop in Singapore where floor space and desk clutter are real constraints, that is a full-featured business PC in a footprint smaller than a paperback book.
AMD Ryzen AI 7 445 — Six Cores, an On-Chip NPU, Radeon 840M Graphics
The Ryzen AI 7 445 is a 6-core / 12-thread processor from AMD's Ryzen AI 400 ("Gorgon Point") series, configured by ASUS at 45 W cTDP in this chassis. It pairs Radeon 840M integrated graphics with an on-chip NPU that AMD rates at up to 50 TOPS — comfortably above the 40 TOPS threshold Microsoft sets for Copilot+ PC certification, which is why this configuration ships with Windows 11 Pro Copilot+PC out of the box. Day to day that NPU means on-device AI features in Windows — live captions, image generation, background effects in video calls — run locally rather than round-tripping to the cloud.
Against the flagship PN55-S90021NL in our range, which steps up to the Ryzen AI 9 HX 470 and Radeon 860M graphics, this Ryzen AI 7 445 build is the sensible middle configuration: full Copilot+ AI acceleration and strong multi-core performance for office and knowledge-work applications, at a lower price point than the top-tier chip.
32 GB DDR5 and a 1 TB PCIe 4.0 NVMe SSD Standard
32 GB of DDR5-5600 memory is fitted as standard across the two SO-DIMM slots, with ASUS documenting a maximum of 48 GB total for this chassis — so a single additional module is the practical upgrade path rather than a full pair swap. Storage is a 1 TB PCIe 4.0 M.2 NVMe SSD, expandable to a 2 TB drive in the same slot per ASUS's specification. For most business software and multitasking workloads, 32 GB is already generous headroom rather than a bottleneck.
Dual 2.5G LAN, Wi-Fi 7 and Quad-Display Output
Wired networking is dual 2.5G RJ45, which is useful either for a resilient wired connection that cannot afford a dropped link, or for bridging two network segments from a single desktop. Wireless is Wi-Fi 7 with Bluetooth 5.4. Video output covers HDMI 2.1, two DisplayPort 1.4 outputs and a USB4 Type-C port, and ASUS documents support for up to four displays from the one unit — well beyond what a typical office desktop needs, and useful for a trading-desk or dispatch-style multi-monitor setup. A front-panel fingerprint reader supports Windows Hello sign-in without a password.
Supplied Locally, with GST Invoice and Singapore Onsite Warranty
SourceIT supplies the ASUS ExpertCenter PN55-S70020NL with a full GST invoice and local Singapore support. ASUS backs this model with a 3-year onsite warranty, so a qualifying hardware fault is resolved at your premises rather than requiring the unit to be couriered away.
Need more graphics headroom or a lower-cost entry configuration instead? The same PN55 chassis is also available as PN55-S90021NL (Ryzen AI 9 HX 470, Radeon 860M, 32 GB) and PN55-S50019NL (Ryzen AI 5 430, 16 GB).

Connectivity & Setup / Expansion
Display and Video Output
Two DisplayPort 1.4 outputs, one HDMI 2.1 output and a USB4 Type-C port together support up to four displays from a single unit. Standard DisplayPort and HDMI cables connect directly to most current monitors; a USB-C to DisplayPort or HDMI cable is needed for a monitor without native USB-C input on the fourth display.
Dual LAN Use Cases
The two 2.5G RJ45 ports support a resilient wired connection, bridging two separate network segments, or keeping a spare wired port available for future re-cabling. Configuration is done in Windows network settings; talk to us if you need a specific dual-LAN topology configured before delivery.
Memory and Storage Expansion
The chassis is tool-free to open for upgrades. ASUS documents a maximum of 48 GB across the two SO-DIMM slots for this configuration and a maximum single M.2 drive capacity of 2 TB — both are user-serviceable after purchase, and we can fit a larger drive or memory kit before delivery on request.
VESA Mount and Desk Placement
A VESA mounting bracket is available as an optional accessory to fix the PN55 to the back of a compatible monitor arm, clearing the desk entirely. At 130 x 130 x 34 mm it also sits comfortably flat on a desk where a VESA mount is not required.
Peripheral and Accessory Compatibility
The front-panel USB 3.2 Gen 2 Type-C and Type-A ports handle everyday peripherals — a USB keyboard, mouse, webcam or external drive — without needing to reach behind the unit. The rear USB4 Type-C port additionally supports high-bandwidth peripherals such as external SSD enclosures or a USB-C dock, and can double as one of the four display outputs when a monitor rather than a storage device is connected. Standard Windows drivers cover the fingerprint reader for Windows Hello enrolment without additional software.
Package Contents & Ordering Information
In the Box
AC power adapter, power cord, screw pack, user manual and warranty card. Keyboard, mouse and the VESA mount bracket are available as optional accessories and are not included as standard.

Frequently Asked Questions — ASUS PN55-S70020NL
Is this a complete system or a barebone unit?
Complete system. The PN55-S70020NL ships with the AMD Ryzen AI 7 445 processor, 32 GB DDR5 memory and a 1 TB PCIe 4.0 NVMe SSD already fitted, ready for first sign-in with Windows 11 Pro preinstalled.
How does this compare with the PN55-S90021NL and PN55-S50019NL in your catalogue?
All three share the same 130 x 130 x 34 mm chassis, dual 2.5G LAN and Wi-Fi 7. This model sits in the middle: the Ryzen AI 7 445 with Radeon 840M graphics and 32 GB of memory, ahead of the entry Ryzen AI 5 430 / 16 GB build and behind the flagship Ryzen AI 9 HX 470 with Radeon 860M graphics.
What does the NPU actually do?
The on-chip NPU, rated by AMD at up to 50 TOPS, runs supported on-device AI features in Windows 11 locally rather than in the cloud, and is why this configuration qualifies for Copilot+ PC certification well above Microsoft's minimum threshold.
Can memory or storage be upgraded later?
Yes. ASUS documents up to 48 GB total across the two SO-DIMM slots for this chassis, and the M.2 slot supports drives up to 2 TB, so both can be increased after purchase if the workload grows.
How many monitors can it drive?
Up to four displays via the two DisplayPort 1.4 outputs, the HDMI 2.1 output and the USB4 Type-C port, per ASUS's specification.
Is a dedicated graphics card an option?
No. Like the rest of the PN-series, the PN55 chassis is built around integrated graphics only — there is no slot for a discrete GPU. If your workload needs one, this Mini-PC family is not the right fit and we can suggest a small-form-factor tower instead.
What does "onsite" warranty mean in practice in Singapore?
An onsite warranty means a qualifying hardware fault is diagnosed and repaired at your premises by an authorised technician, rather than requiring you to ship the unit back to a service centre and wait for a return. SourceIT coordinates the onsite claim on your behalf as part of the local support that comes with every unit we supply.
Does it come with a Singapore warranty and a GST invoice?
Yes. Every ASUS ExpertCenter PN55-S70020NL sold by SourceIT comes with local Singapore support and a GST invoice; ASUS backs this model with a 3-year onsite warranty.
