Wonder who the OEM of the unit itself is, unless Enermax makes power supplies? The name on the inside is what matters, much more than the name on the outside (which only matters for warranty / support). There used to be a forum post somewhere with almost all the known decent-brand power supplies of the last 10 years or so, and who the OEM's are for the various models. When in doubt, Seasonic helps you out - get a Seasonic and no need to worry.
