I use the same PSU for my rig and since building it, the PSU has been clicking, best way to describe it is like a cricket, rather annoying.
After posting on the OCZ forum a mod told me he didn't really know what it was since the sound didn't stop when the fan blades weren't rotating. He then directed me to a post on how to power the PSU with only a few fans as the load, but due to me not wanting to stick a paper clip into a live power supply I'm pretty certain I'm going to buy a new PSU.
When the PSU doesn't make the clicking sound, it is pretty silent. The blue LED fan is pretty funky and as posted above, the cables aren't very flexible but apparently glow when introduced to UV light.
Build quality seems pretty nice, just a shame the clicking sound mine makes, but I'm sure it's only a rare fault. Other than that, seems like a decent PSU.
Just a warning, mine came with a US plug connector, so I had to use my old Power cable, either that or buy a US > UK plug adapter.
