Display and Video Output Compatibility

Two DisplayPort 1.4 outputs, one HDMI 2.1 output and a USB4 Type-C port together support up to four displays. 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 can be used for a resilient wired connection (one active, one standby), for bridging two separate network segments such as a corporate LAN and an isolated POS or lab segment, or simply to keep a wired link available on both ports 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.

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 are suited to 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 be used 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.

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.

Is this a complete system or a barebone unit?

Complete system. The PN55-S50019NL ships with the AMD Ryzen AI 5 430 processor, 16 GB DDR5 memory and a 1 TB PCIe 4.0 NVMe SSD already fitted, ready for Windows 11 Pro setup on first boot.

What does "Copilot+ PC" actually mean for this unit?

It means the Ryzen AI 5 430's onboard NPU meets Microsoft's minimum throughput requirement (40+ TOPS) for Copilot+ PC features, so functions like Windows Studio Effects and Recall run using on-device AI processing rather than a cloud round-trip, where Windows supports them.

Can I add a second memory module or upgrade storage later?

Yes. The unit ships with a single 16 GB DDR5 module in one of two SO-DIMM slots, so a second module can be added for a dual-channel 32 GB (or higher) configuration. The M.2 slot supports drives up to 2 TB for a later storage upgrade.

Why does it have two LAN ports?

The dual 2.5G RJ45 ports support use cases like a resilient wired link, bridging two network segments, or keeping a spare wired port available without needing a USB dongle. Both run at up to 2.5 Gbps.

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, all supporting 4K resolution per ASUS's specification.

What is the difference between this and the PN55-S90021NL in your catalogue?

Both share the same 130 x 130 x 34 mm chassis, dual 2.5G LAN and Wi-Fi 7. The PN55-S90021NL steps up to the AMD Ryzen AI 9 HX 470 processor with Radeon 860M graphics and ships with 32 GB of memory as standard, aimed at heavier multitasking or AI-assisted workloads.

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-S50019NL sold by SourceIT comes with local Singapore support and a GST invoice; ASUS backs this model with a 3-year onsite warranty.
