  • 20-core Core Ultra 7 265KF hits 5.4 GHz for responsive gaming and multitasking
  • 128 GB DDR5 memory keeps heavy workloads and open worlds running smoothly
  • RTX 5070 with 12 GB GDDR7 drives high-fidelity 1440p and entry 4K play
  • 1 TB NVMe SSD loads games and apps in seconds
  • 240 mm liquid cooler and 850 W supply sustain peak performance under load

Built for high-refresh 1440p gaming

This ArsenalPC desktop pairs an Intel Core Ultra 7 265KF 20-core processor with an NVIDIA GeForce RTX 5070 graphics card. The system ships with Windows 11 Home installed and includes 128GB of DDR5 memory alongside a 1TB NVMe SSD. It is aimed at enthusiasts who want a liquid-cooled, WiFi-ready rig with RGB lighting for immediate play.

Graphics card memory decides 4K viability

The RTX 5070 inside this build carries 12GB of GDDR7 video memory. That frame buffer is the single specification that determines whether the system can hold high-resolution textures at 4K without swapping to system RAM. Buyers targeting consistent 4K ultra settings should verify that 12GB meets their texture budget before purchasing.

240mm liquid loop keeps the 20-core CPU in check

A 240mm all-in-one cooler dissipates heat from the Core Ultra 7 265KF, allowing sustained 5.4GHz boost clocks under load. The 850W power supply delivers headroom for the GPU and memory without running near its limit, which helps keep fan curves quiet during typical gaming sessions.

Questions about this item

How does the 5.4GHz 20-core Core Ultra 7 265KF perform inside this liquid-cooled build?

The 240mm liquid cooler keeps the 20-core processor at its 5.4GHz boost during sustained gaming and heavy multitasking without thermal throttling.

What bandwidth does the RTX 5070 12GB GDDR7 actually deliver on the Gigabyte C301 GLASS motherboard?

The graphics card runs at full PCIe Gen 5 speed on the Intel LGA 1851 platform, so the 12GB GDDR7 memory feeds the GPU without a bottleneck.

Will the 240mm radiator and 128GB DDR5 fit in the Gigabyte C301 GLASS case without clearance issues?

Yes, the C301 GLASS chassis is designed for 240mm top-mount radiators and four 288-pin DDR5 slots, so the 128GB kit and liquid cooler install cleanly.
