Intel Core i5-9400 OEM desktop processor

Intel Core i5-9400 desktop processor

The Intel Core i5-9400 is a six-core desktop CPU built on the 9th Gen architecture. Base frequency sits at 2.90 GHz with Intel Turbo Boost Technology 2.0 lifting it to 4.1 GHz under load. Integrated Intel UHD Graphics 630 handles everyday visual output without a discrete card. The 65 W TDP suits mainstream gaming and content creation systems.

Compatibility checklist before ordering

Verify the motherboard uses the LGA 1151 socket and an Intel 300 Series chipset; earlier chipsets are not supported. Ensure the BIOS recognises 9th Gen Core processors or plan a firmware update. Confirm the CPU cooler mounts on LGA 1151 and is rated for at least 65 W. System memory must be DDR4.

Build integration notes

The processor drops into an LGA 1151 (300 Series) board and runs with standard DDR4 memory. Integrated UHD Graphics 630 frees a PCIe slot and PSU cables when a discrete GPU is not required. Intel Optane Memory and SSD support is available on compatible 300 Series platforms. The 65 W thermal envelope keeps cooler and power-supply demands modest.
