Are you looking for reviews mate? ... I dont have that exagt same PSU however i have a higher version from the same series ( ST75F ), I am very impressed with it! Very quiet ( In my opinion! ) ... Good and reliable! ... The only thing is .. it isnt true Modular i mean you can have 6 satas or nothing ... 2 PCI-Express or nothing!
I have received this PSU and installed it into a new PC since Monday 31st March. It certainly is quiet, however if it's silent in my room I can hear a constant humming / buzzing noise.
