I actually had good experiences with Enermax. My last PSU held nearly 4 annual. This on the contrary - only 5 months. Also, the quality has suffered slightly in recent years. On my first power supply cables were encased for connections - in the here that was no longer the case. Only the two fixed integrated cables are not provided with an additional protection.
I hope to have just caught a Monday model, because I was happy with the power supply on the whole.
