Specification for Mean Time Before Failure in hours:
50,000 Antec SL
80,000 Antec True & Neo
100,000 Seasonic, Fortron, etc.
Of course this reliability data only concerns the unit itself, not whether it will cause damage to other components when it fails or otherwise is overloaded. Any decent PSU has sufficient protection and simply trips its own breaker. A crap one could be expected to destroy only itself. One that destroys other hardware must be exceedingly shoddy. Antec is not a manufacturer or supplier to OEM's and so is really a small player but has relatively strong retail sales. So other than the lower reliability spec, it is conceivable that a high proportion of motherboard damage could involve Antec since it would imply self-assembly by possibly inexperienced users. As for their reputation, well, it is primarily a marketing company.
