Pros: Modular. Sufficient power for two video cards. Cables good quality.

Cons: When I first received this product everything was fine for the first few hours. I quickly learned that a few hours after the power supply was in use it starts emitting a high-pitch chirp on an irregular yet highly annoying pattern. I received a replacement from newegg only to find that the replacement emitted the same chirp all the time. It also had a lose fan and that clunked around making a new annoying sound. Silverstone's tech support is very limited and the RMA process requires printing, scanning, and emailing the form. Obviously, this means if you don't have a scanner you have to find one. They also require you to pay for the shipping of their defective product to them.

Overall Review: I will never buy a power supply from this company only for the fact that I don't want to spend another month and a half without a computer because my power supply in being shipped for replacement.
