15.6 QHD 240Hz gaming laptop

This 15.6-inch laptop pairs a QHD panel at 240 Hz with an Intel Core i7-12700H and an NVIDIA GeForce RTX 3070 Ti. It targets gamers and creators who need high refresh rates and 14-core processing in a portable chassis. Windows 11 Home ships pre-installed. The 32 GB of DDR5 4800 MHz memory and 8 TB of PCIe 3.0 x4 NVMe storage are installed by the system integrator.

Sustained load behaviour

The RTX 3070 Ti operates at a 150 W TGP with a 1510 MHz boost clock, while the i7-12700H can reach 4.7 GHz turbo across its 14 cores and 20 threads. Upgraded thermal interface materials applied during integration aim to lower peak temperatures and reduce throttling during extended CPU and GPU workloads. Fan noise is minimised as a result of the same thermal work. The dual-channel DDR5 configuration supports memory-intensive multitasking without bandwidth bottlenecks.

Upgrade context

This configuration replaces a stock Helios 300 unit that typically ships with less RAM, a smaller SSD and standard thermal paste. The jump is worthwhile when workloads demand 32 GB of fast DDR5, 8 TB of NVMe capacity and the integrator's validated thermal tune for sustained 150 W GPU power. Buyers moving from a base model gain the 240 Hz QHD panel and the higher TGP 3070 Ti in a single step.

Questions about this item

How loud and hot does the RTX 3070 Ti get when the laptop runs all day at its 150W TGP?

The RTX 3070 Ti operates at a 150W max TGP with a 1510 MHz boost clock. HIDevolution applies upgraded thermal interface materials to lower system temperatures, prevent throttling during intensive tasks, and minimise fan noise for better reliability.

What must I already own to use the 15.6" 240Hz QHD display and the RTX 3070 Ti with 8GB GDDR6?

Windows 11 Home is pre-installed and the system includes 32GB DDR5 4800MHz RAM plus 8TB PCIe 3.0 x4 NVMe SSD storage. No extra parts are required for the display or GPU to function out of the box.

Will my older SATA SSDs work alongside the 8TB PCIe 3.0 x4 NVMe storage already installed?

The laptop uses M.2 PCIe 3.0 x4 NVMe slots for its 8TB (2x4TB) configuration. SATA drives are not compatible with these slots, so older SATA SSDs cannot be added internally without a separate adapter.
