System built around Core Ultra 7 265KF and RTX 5080

This desktop pairs a 20-core Intel Core Ultra 7 265KF running at 5.4 GHz with an NVIDIA GeForce RTX 5080 carrying 16 GB of GDDR7 memory. It targets enthusiasts who need high frame rates at 4K and creators who rely on GPU acceleration for rendering or encoding. The 128 GB of DDR5 across four slots and a 4 TB NVMe SSD provide headroom for large projects and game libraries. Windows 11 Home is pre-installed and the machine ships tested.

240 mm liquid cooler sustains CPU clocks under

A 240 mm liquid cooler keeps the 20-core processor near its 5.4 GHz base frequency during extended gaming or compile workloads, reducing the throttling seen with air towers in compact chassis. The 1000 W power supply delivers stable current to the RTX 5080 and all peripherals without hitting protection limits. VR-ready certification means the GPU maintains the sustained throughput required for headset use over hours.

Gigabyte C301 glass chassis shows internals

The Gigabyte C301 case uses tempered glass panels to display RGB-lit components while offering tool-free entry for drive or memory changes. Four DDR5 slots are fully populated at 128 GB, so future expansion requires module replacement rather than simple addition. A single 4 TB NVMe drive occupies one M.2 slot, leaving room for additional solid-state storage if the board provides more connectors. Wi-Fi and Bluetooth are integrated for wireless peripherals.

Questions about this item

How much power does the 1000W supply draw when the RTX 5080 and Core Ultra 7 265KF run all day?

The 1000W power supply is sized for the 5.4GHz 20-core CPU and RTX 5080 under sustained load; the 240mm liquid cooler keeps CPU thermals in check during extended sessions.

Does the motherboard have free DDR5 slots so I can add more memory later?

All four DDR5 slots are populated with the 128GB kit, so no slots remain for expansion without removing existing modules.

Can I keep using my current monitor that only has HDMI 2.0?

The RTX 5080 connects via PCI Express x16 and provides modern display outputs; an HDMI 2.0 monitor will work at its native resolution and refresh rate.
