Product Description

This Intel Core i5-11600K desktop processor is in Good condition and has been fully tested to ensure 100% stability and proper operation.

Powered by Intel’s 11th Generation Rocket Lake architecture, the Core i5-11600K features 6 cores and 12 threads. Operating at a 3.9 GHz base clock with a Turbo Boost of up to 4.9 GHz, it delivers strong single-core and multi-threaded performance for 1080p and 1440p PC gaming, everyday multitasking, and content creation.

As an unlocked "K" series processor, it supports manual overclocking on compatible Z-series motherboards. It also brings support for PCIe 4.0 connectivity, allowing faster communication speeds with modern GPUs and M.2 NVMe SSDs.

Key Features & System Requirements:

  • PCIe 4.0 & DDR4 Support: Native support for PCIe 4.0 expansion lanes and up to DDR4-3200 memory speeds.

  • Integrated Graphics: Includes Intel UHD Graphics 750 (Xe Architecture) for display output without requiring a dedicated graphics card.

  • Unlocked Overclocking: Fully unlocked multiplier allows performance tuning when paired with a Z490 or Z590 motherboard.

  • Cooling & Power Requirements: Includes the CPU only (does not include a heatsink or cooling fan). Rated at a 125W TDP, so an aftermarket air cooler or liquid cooler is required for optimal performance.

  • Socket Compatibility: Fits Socket LGA 1200 motherboards (Intel 500-series chipsets and compatible 400-series chipsets with a BIOS update).
