Performance of this power supply is where we see this power supply shine. While it isn't the coolest power supply, it is the quietest power supply I have tested, which means that those of you with water cooling systems can use this power supply without really adding any noise. Power levels are very good with the 5v and 3.3v lines being almost perfect, with less than 1% variation from the rated voltage on our test system.
