I recently did a lot of research trying to pick out the quietest and most efficient power supply for a rebuild of my server. I read reviews here, Jonnyguru, and at TPU, and numerous forum threads. I ended up deciding on a Seasonic unit. While I believe they're the most efficient and well built, there was a bit more to the decision than that. They design and build them themselves, and every model they produce is trustworthy.
Always read good things but never had a chance to try their products now is great time to start, especially since i am in need for a good solid keyboard in the near future as mines getting pretty worn down
