Pros: This is a great power supply. It's Antec branded but the OEM is SeaSonic, the most respected power supply builder out there. It's nice to see a quality modular power supply in this price range. The fan is very quiet on my unit. I cannot hear it over any of the other fans in my case and none of them are loud either. Also, there are no squeals or other odd sounds when stressed. It works just as intended and does it quietly.
Cons: It only comes with two PCIe cables, even though it has the capability of plugging in four. This is a non-issue for most people, but you may want to watch for this if you have cards that require two plugs each and you want to do SLI or CrossFire. The cables are stiff. Although this is a mark of the quality of the wires and the cable sleeves, it can cause some problems because there is very little flex. For example, I was swapping out my video card and the cable supplying power to one of my hard drives was so stiff, that the plastic SATA power connector actually broke on one side as I was gently applying pressure on the cable while maneuvering parts. I had to dock an egg for this. A perfect score requires perfection. It was my fault, but I've never had this happen before. If there was more flex in the cables this would never have happened. Otherwise, this power supply is a top notch unit.
Overall Review: I've had this power supply for a year now without a single issue. I'm currently running the following hardware with this power supply: Asus Maximus IV Gene-Z Intel Core i7-2700K Corsair Vengeance DDR3-1600 4x4GB XFX Radeon HG6950 (uses 6-pin and 8-pin auxiliary power) 4x Mechanical HDDs 1x SSD 1x BD drive 5x fans Even overclocked, this power supply runs like a champ.
