Hmmm...I do not know the serial number is used to identify. Actually, I think the first 8 numbers of the serial number is the lot code itself. So, if the lot code falls in that range (194448xx to 201148xx), yours is affected.
If I were you, I would submit a ticket here:-

It is good to double check with someone from Corsair headquarter.
I did - PSU is fine, this is the information I received two times from Corsair. When I was asking why it seems like the LOT number is one of the affected ones related to the threads you can find online they told me it's not true.
Quote Corsair service staff: "The serial number is the important number. LOT number is not meaningful in this case. The information you received about the LOT number is wrong"
Ok, calm down Corsair
Everything seems to be fine with my PSU. Case closed
