I9 9900k Aorus Z390 Ultra
2x16gb Corsair (and tried XPG)
850w corsair psu (and tried 850 evga)

Got everything built, 24 pin plugged in. 8 pin CPU plugged in and everything else. Getting error code 7f on boot. Removed GPU, same error code. Removed battery and jumped cmos pins. Same issue. Biggest thing is I also have no video output and no USB output. Keyboard and mouse are dead, no rgb lights on (although I vaguely remember them coming on the first time and never since) I've tried new ram, I've tried a new PSU. Still having the same issue. This is my 2nd board as my last one was an rma (different brand board) really hoping its something simple I'm over looking. Any help would be greatly appreciated!!!
