System configuration

This ArsenalPC desktop pairs an Intel Core Ultra 7 265KF 20-core processor running at 5.4GHz with a GeForce RTX 5070 graphics card holding 12GB GDDR7 memory. The platform includes 128GB DDR5 RAM across four slots and a 4TB NVMe SSD. It targets gamers and creators who need high core counts and modern GPU memory bandwidth in a ready-to-use Windows 11 Home system.

Thermals and power

A 240mm liquid cooler handles the CPU thermal load while the 850W power supply feeds the complete build. The liquid loop keeps the 20-core processor at stable temperatures during sustained workloads. The power unit provides headroom for the RTX 5070 and all installed components without requiring an external upgrade.

Included extras

The Gigabyte C301 GLASS chassis adds tempered glass panels and RGB lighting for visual customisation. Integrated WiFi removes the need for a separate network adapter. Windows 11 Home is pre-installed and the system ships tested, so the machine is operational immediately after unboxing.

Questions about this item

How do I install the 240 mm liquid cooler in the Gigabyte C301 GLASS case and what step is often missed?

Mount the radiator to the case fan positions, connect the pump header to the CPU_FAN connector on the LGA 1851 motherboard, and plug the ARGB cable into the board’s 5 V header so the RGB lighting syncs with Windows 11.

What maintenance will the 240 mm liquid cooler and 850 W power supply need later?

Dust the radiator fins and case filters every few months; the sealed 240 mm loop requires no fluid changes, and the 850 W PSU fan bearings are the only moving parts that may eventually need replacement.

Which limit appears first when the Core Ultra 7 265KF and RTX 5070 run sustained loads?

The 240 mm radiator reaches thermal saturation before the 850 W power supply hits its output ceiling, making coolant temperature the practical bottleneck during extended gaming.
