Built for competitive gaming on a 15.6" 144Hz panel

The Katana A15 pairs an AMD Ryzen 9 8945HS processor with an NVIDIA RTX 4070 laptop GPU. Eight cores and sixteen threads drive high frame rates in modern titles. Windows 11 Home is pre-installed. The 15.6 inch FHD display refreshes at 144Hz for smooth motion clarity.

16GB DDR5 and 512GB PCIe SSD set the working ceiling

Sixteen gigabytes of DDR5 memory handles current games and multitasking without paging. The 512GB PCIe solid-state drive loads levels quickly but fills fast with large AAA install sizes. Users building a deep library will need external or internal expansion soon.

Cooler Boost 5 and a full port array support

The Cooler Boost 5 thermal design sustains performance during long matches. Connectivity includes two USB 3.2 Type-A ports, one USB 2.0 port, one USB 3.2 Type-C port, HDMI, RJ-45 Ethernet and a headphone/microphone combo jack. A standard RGB keyboard and integrated webcam complete the package.

Questions about this item

Will my older USB 2.0 mouse and keyboard work with the two USB 3.2 Type-A ports?

Yes, the two USB 3.2 Type-A ports are backward compatible with USB 2.0 devices, so existing peripherals will function normally.

How can I confirm the 144Hz panel is actually running at 144Hz after I set up Windows 11?

Open Settings > System > Display > Advanced display and verify the refresh rate dropdown shows 144Hz for the built-in 15.6" FHD screen.

Does the box include an SD card reader or do I need to buy a separate USB adapter?

The laptop has no built-in SD reader; the supplied accessories are the power adapter and documentation, so a USB adapter must be purchased separately.
