Question MSI B560 Tomahawk not recognising 11600K?

[Captain Hillman]

I'm trying to setup a system using a brand new MSI B560 Tomahawk board, with a new Intel i5 11600K. Unfortunately the build is not booting (but the board and fans do get power) and the CPU debug LED shows red.

Board: MSI B560 Tomahawk
CPU: Intel i5 11600K
RAM: 2x8GB Corsair DDR4 Vengeance RGB PRO
PSU: EVGA 650W BQ Bronze
GPU: GTX 970

Here's what I've tried/checked so far:

• CPU is seated correctly (without bent pins).
• RAM is in correct slots (also tried booting without RAM).
• PSU has 2x4pin CPU cables, these are slot into the 8pin CPU PWR socket on the board.
• Tried without the GPU inserted.
• Cleared CMOS.

I've read about updating the BIOS from a USB stick, would I need a different CPU to slot in and do this?

I've tried loosening the CPU cooler and reseating the CPU power cable (no luck on either).

The pins on the board look okay to me, but there are some marks on the CPU (these only appear in certain light, but I can't tell if they're serious). Could it be these?
