Stealth A18 AI+ 18.0" UHD+

The MSI Stealth A18 AI+ A3HWIG-028US is an 18.0 inch gaming laptop built for creators and gamers who need high resolution and AI compute on the move. It pairs a 10 core AMD Ryzen AI 9 365 processor with an NVIDIA GeForce RTX 5080 Laptop GPU and 16GB video memory. The 2560 x 1600 non touch screen runs at 120 Hz for smooth motion.

Sustained load on Magnesium Aluminum Alloy Chassis

The Midnight Black Magnesium Aluminum Alloy Chassis measures 15.74" x 11.41" x 0.94" and weighs 6.39 lbs, providing a thin envelope for the RTX 5080 and Ryzen AI 300 Series silicon. Max Q optimisation balances clock speeds and thermals so the system maintains performance during extended rendering or gaming sessions. Dual fans and vapour chamber cooling move heat away from the CPU and GPU without throttling early.

32GB DDR5 5600 and 2TB NVMe Gen4x4 decide fit

Memory is 32GB DDR5 5600 soldered to the board with no user accessible slots, so capacity is fixed at purchase. Storage is a single 2TB NVMe Gen4x4 drive that can be swapped for a larger module if needed. Buyers who need more than 32GB RAM must choose a different model; those who need more storage can upgrade the SSD later.

商品問答

How much heat and noise should I expect from the Ryzen AI 9 365 and RTX 5080 when the laptop runs all day?

The system pairs a 10-core Ryzen AI 9 365 with an RTX 5080 Laptop GPU in a chassis measuring .94 inches thick, so sustained workloads will produce noticeable fan noise and surface warmth.

What must I already own to use the 2.5 Gb LAN port and the HDMI 2.1 output on this Stealth A18 AI+?

You need a router or switch that supports 2.5 Gb Ethernet and a display or capture device with an HDMI 2.1 input to use those ports at full speed.

Will my existing DDR5 5600 SO-DIMMs and Gen4 NVMe SSD work alongside the factory 32 GB memory and 2 TB drive?

Yes — the laptop uses DDR5 5600 memory and a Gen4x4 NVMe slot, so compatible DDR5 5600 modules and Gen4 NVMe drives can be added or swapped without issue.
