RM750w

After some bad weather around here(thunders).. My system crashed 2 times with the log " kernel processor power" my friends that work on some it departm say thats probb because of a faulty psu... So i ask, what should i do? Rma the psu? All around these blogs ppl keep saying that rm series sucks pretty bad.. But, as a costumer... I payed 115€ more less 130dollars... Not a mid range for sure
