Product Description

This Intel Core i5-9600K desktop processor is in excellent condition and has been fully tested and verified to ensure stable performance and reliable operation.

Built on Intel's 9th Gen "Coffee Lake Refresh" architecture, this 6-core processor features boost clock speeds reaching up to 4.6GHz and 9MB of Intel Smart Cache. With an unlocked multiplier for straightforward overclocking, it delivers fast single-core response and dependable mid-range gaming performance.

Designed for LGA1151 300-series motherboards (Z390, Z370, B365, B360), it offers native support for dual-channel DDR4 memory and features integrated Intel UHD Graphics 630 for display output without needing a discrete graphics card.

The processor contacts and components have been thoroughly inspected, stress-tested, and validated for complete stability. It will be packaged safely in an anti-static tray or protective casing for secure transport.

Note on Cooling:

  • The "K" designation means this processor is fully unlocked for overclocking. It has a 95W TDP (Thermal Design Power) and does not include a stock box cooler.

  • We recommend pairing this CPU with a quality single-tower cooler (such as the Thermalright Assassin X 120R SE) or a dual-tower cooler for silent and reliable thermal performance.
