Before you buy or sell a used i5-9400F
The F suffix means this six-core, six-thread processor has no integrated graphics, so your PC will not display an image without a dedicated graphics card. Standard i5-9400 chips with onboard video and the unlocked i5-9600K are separate parts.
Rated at 65W with a 4.1GHz boost for DDR4 builds, it fits only 300-series LGA1151 motherboards. Early H310, B360 and Z370 boards often need a 9th-gen BIOS update before booting it, particularly for later R0 stepping chips.
