Pros: Reliable, easy to use, electrically efficient, fits my case well (Bitfenix Shinobi)

Cons: Not modular (but you know that going in, so whatever).

Overall Review: PSU reviews are fairly simple. Seasonic products, for me at least, have always worked right out of the box, consistently, and without issue for a long time. I've owned this PSU for 15 months now, so I can't speak to super longevity, but I've been running a system with about 420 watts TDP, and have had 0 problems. I've got an Intel 3570k, a Radeon HD 7950, and both are overclocked without problems. I wish the cables had been modular for slightly easier setup, but they certainly have a modular version available in their M12II series, so get that if that's important.
