EVGA SuperNOVA serial sticker peeling

[ubersonic]

So yeah, had this PSU just over 18 months and noticed when I was changing my case that the warranty/serial sticker on it is starting to peel. I guess this is due to the eggshell paintwork on these PSU's and the sticker being on the warmest part of them, but if it comes off will they still honour the warranty? is the any markings inside they can use to identify it?

Thanks.
