And I just looked it up. Its gfot a 10 year warranty ! The motherboard may be a loss, but maybe I can get an RMA !
I actually have a rather old enermax PSU and it broke about 3 months before the end of the 5 year warranty. I wasn't sure I should RMA because of the high cost for sending it to RMA (not US, small country so international postage and PSUs aren't that light weight). Anyway the postage was maybe $40 less than a new unit. But then I don't like to waste stuff that could easily be repaired and now it's around 10 years old and powering my 3900x so the RMA was for sure worth it.
However when it failed, nothing else broke and never new what actually failed. Turned PC off in evening and when trying to turn it on the next day absolute nothing happened. Simply didn't power on.
Long story short, I would only RMA it if you actually trust it. The hassle of worrying and another defect usually are not worth it.
