funny topic, read a couple of pages before realising how old it is
Just had to chip in and state I have a hiper type r modular 580w black for 2 and a half years now and it's still working fine. Was one of the best ever investments (although expensive) I made in self building because of its design and noise output, very quiet, I couldn't even hear it unless I put my ear up close - was a vast improvement over cheap psus that came with cases.
it's powered 4 mobos, 3 cpus including the power hungry amd 6000+ (125w), a number of graphics cards including 8800gtx currently plus loads of other system components.
I think the combination of the msi k9n ultra with the 6000+ and 8800gtx, 4gb high speed ram, 3 hds and other stuff put it under a great deal of strain.
When I moved to my E8400 and asus p5n-d build I didn't have a suitable power cable set up for the 8800gtx and a loud high pitch sound came from inside the hiper. I think the cause was because where you need 2 molex to the 2nd pci-e 6 pin well one of the molex lines I had other devices on it. Rearranging things so that the gtx had 2 dedicated molex stopped the high pitch sound (that only happened when I started a game). So it's important to take good notice of the advice hiper give on cable setup whenever possible.
the back fan is showing its age with louder movement noise where before it was silent.
It seems to be doing its job still but I might replace it with a corsair TX750W and put the hiper in a music production system (if the back fan is not too loud).
