Hi all. I bought an XFX TS 420 for a low power server and within 6 months it's blown up (complete with dramatic cloud of smoke). I was lead to believe it's a "Tier 2" re-badged Seasonic and of very good quality. Needless to say I won't be replacing my PSU with the same model as my trust in the unit has been shaken. I do wonder though, how is the Tier system calculated and is it really worth paying attention to when choosing a PSU?
edit.. should be a TS 430 as pointed out by satrow.
