Provided power to all pieces in my computer.
Very loud! Advertised as silent, fan is supposed to turn off under light load, but this ran at full speed at all time producing a very annoying tonal sound.

Also, SATA power connectors are reversed compared to their standard direction, which makes wiring somewhat more contrived than needs be.
Perhaps not all units do this, but I bought this PSU for a silent computer build and it completely ruined it from that perspective. Replaced it with an XFX Black Edition 750W, which in hybrid mode does not emit a decibel.
