To be honest, I don't really like the idea of having PSU tier lists. Even though a PSU may get into Tier 1, that doesn't mean it's perfect. There are users on here that buy a specific power supply because it's in Tier 1 but then they have problems with it and of course it's our fault.
Anyways, I'm usually much happier just suggesting a power supply based on the specifications of a user's build. I usually recommend the Corsair RMx lineup when a user needs high wattage but isn't going for hardcore overclocking. For hardcore overclocking, something like the EVGA SuperNOVA P2 or T2 series would be a better fit.
