Conclusion:
The 650A power supply from GlacialPower is certainly a great power supply to consider if you're building a new computer. Now only will it's 80Plus certification help you save power, but it will also contribute to an ultra-silent running power supply. Matched with the right system, you may even see performance like I did with the fan rarely needing to turn on at all! This product has definitely entered my list of recommended power supplies.

Pros:
High efficiency
Fan will completely shut off when wattage falls below a set threshold
Overall quiet operation
Fan remains running for a couple minutes after system shut down to help prolong component life by proper cooling

Cons:
Fan seemed to have a very accute rattling sound to it at times
