• Intel Core Ultra 5 250K Plus processor in retail box
• Intel does not list a cooler for this boxed K processor — plan an LGA1851-compatible cooler

• 18 cores and 18 threads: P-cores handle games and active applications, E-cores take background tasks and multi-threaded work.
• Unlocked multiplier for overclocking on boards that support it.
• DDR5 up to 7200 MT/s in two channels, up to 256GB of memory.
• Integrated Intel Graphics (4 Xe-cores) drives displays without a graphics card — useful for office builds and troubleshooting.
• The built-in NPU (13 TOPS) runs AI features locally in supported applications.
• 125 W base power, up to 159 W turbo: budget for a capable cooler and power supply.

• It will not fit LGA1700 motherboards (Intel 600/700-series) — LGA1851 and Intel 800-series only.
• No DDR4 support — DDR5 only.
• Older 800-series BIOS versions may not recognise it until updated.
