Is it only the 580w Type-R Hiper's that are dodgy?
I've got the Type M 630w, I've owned it for about 4 years, and it's been in at least 4 different systems since then, and it's still going strong to this day, it's currently powering my partners i7 system o/ced to 4GHz with an 8800GTX, and it's solid imo.
I've opened it up in the past to clean out all the dust, and it has the same looks as a lot of the high end PSU's around, the layout of the components is extremely clean, and the build quality is excellent imo, so that's what made me think that it must only be the 580w ones that are crap.
