Hi, I recently buy this PSU, in the beginning i didn't check the voltage values, but yesterday I use HWmonitor and I got frecuently -14.4v~ in the -12v, this is normal? in the other sensors i got normals values. you think I need to use de warranty for a exchange? thanks for the replies.

-12V - This rail is pretty much obsolete now and is only kept on to provide backward compatibility with older hardware. Some older types of serial port circuits (e.g. RS-232) required both -12V and +12V voltages, but since almost no one except industrial users use serial ports anymore, you, as a typical home user, can pretty much disregard this rail.
