Uh, had 2 Tagan PSU's and neither have failed. and that's over a period of 5 years.
My 530W Modular one currently runs a GTX 280, E6600 @ 3.6 ghz, 5 HDD's.... with no faults.
I had the same 480W Tagan PSU in my last 3 PC's
I had it running pretty much 24/7 over 5 years (F@H) & never let me down.
Sold it recently for £30. I only paid £48 for it new, 5 years earlier !!
I've recommended them to others in the past, although you'll always get some people prefer to pay £150 for a so called better item.
