Question Anyone have an explanation

[Affeqs]

Just bought a pc and have no clue on what this is, it's not in a pci slot. It has 2 things connected to it that seem to be a light bar or something. Only connected to them and the psu??

Old school cold cathode light.

Is that a Corsair CX500M powering this new PC? I would not recommend doing that.
