9400f don't have igpu.
what gpu did you try?
brand and model of this 500w psu?
motherboard might need bios update to work with 9th gen

many thanks... i dont understand though, the 9400f is listed there but then says na under gpu frequency (not supported). is that an oxymoron or what. excuse my ignorance... and to add insult to injury the other cpu isnt supported neither... some luck,,, schoolboy begginners errors eh... that said, it came as a recomendation with the board on ammazon so I thought itd be ok.. lesson is do my homework and dont be a dumb ass eh?

if you scroll to the right, you see the bios version require for 9400f.

what the brand and model of the psu?

check for bend pin on the motherboard socket?
