Strange light

[Hot74rod]

I lost all power on my computer so I replaced the power supply and I'm getting a strange purple flashing light above the normal LED status lights. Still no power just that light flashing. Anyone have any ideas?

Hello, @Hot74rod 

We apologize for any inconvenience caused by the delayed response.
As we are uncertain about the specific indication of the purple LED light you described, could you please provide further clarification on whether the LED indicator is located on the chassis, the PSU, or elsewhere?
Regarding the power-on issue, we recommend you refer to the TUF GAMING B460M-PLUS user manual to ensure all hardware and power connections are correct, update BIOS if needed, and consult the following FAQs for troubleshooting:
