Question Inhave this working CX600M, it doesn't work with older systems?

[Ayatollah]

The PSU is known to be working but it doesn't work with LGA 1155 even tho everything is plugged in, is this because it's unsupoorted because its so new?

That PSU and every other green labelled unit from Corsair were known to be a dumpster fire, seriously. You should get rig of the unit.
