Pros: Modular PSU Long power cable 10 year warranty

Cons: A strange sound does rev up with this PSU. It sounds like a low rhythmic hum going in and out. I'm not sure what it is. I don't think it's not coil whine. I have a clean setup, and all screws are tight, so I don't think it's vibration. It's definitely from inside the PSU, placing my hand on the outside does not stop the sound, but if I tap on the unit it will stop making the noise for about 30 seconds. I've never done a RMA before, but I'm considering it with this item because while I don't need a completely quite unit, this is the kind of sound to drive me crazy.

Overall Review: From what I can tell, this is a good unit, but the sound that comes from it makes me not want to use my computer. I have my rig set up in my living room so the computer is about 9 feet away from be, but when I am doing anything silent like word processing or web surfing, I can only hear this low rhythmic sound coming from the PSU. While the price to power performance is great, I can't recommend this to anyone who might find this sound distracting.
