Connectivity includes Wi-Fi 6E AX211, Bluetooth 5.3, Gigabit LAN, three USB-A 3.2 Gen1 ports and an audio combo jack.

Questions about this item

At what temperature does the Core Ultra 9 275HX start to throttle during long sessions?

The processor runs at a base clock of 2.1 GHz and can boost to 5.4 GHz; sustained heavy loads will push it toward its thermal ceiling, so adequate airflow and the 240 W adapter are needed to keep clocks high.

How loud do the fans get when the RTX 5070 and CPU run flat out for hours?

Under continuous gaming the cooling system ramps up to move heat from the 24-core CPU and 8 GB GDDR7 GPU, producing noticeable fan noise that rises with load but remains within typical gaming-laptop levels.

Does the 1 TB PCIe Gen 4x4 NVMe drive come installed or do I need to add it myself?

The 1 TB NVMe SSD is factory-fitted, so the laptop boots to Windows 11 Home straight out of the box with no extra storage required.
