Pros: Great PSU for light to moderate load system. I was upgrading my NAS, which doesn't need a huge power supply, but I wanted a quality PSU that would last a long time and be energy efficient since it's a 24/7 use. The 80 Plus Gold certification, eco-mode and 7 year warranty are great. It's nice and quiet -- I keep the NAS in the basement, but I couldn't even hear it when I had it in my office when installing/configuring the OS. With the sleeved and modular cables, it made for a great clean and easy setup.

Cons: None so far.

Overall Review: I already had an 850 G2 in my main system which is overclocked and cooled by phase change. I've been hesitant to do a modular PSU for years since they first came out (not convinced of their reliability and connections) and used to try and find high end PSUs that weren't modular (which is getting hard). But, they seem to have come along since modular PSUs first came out and I'm very satisfied with the performance of both G2s I have, plus enjoy not routing and hiding extra unused wires.

Pros: Great upgrade for a notebook or laptop over the typically slow stock drives. I used this replace the stock 5400RPM drive in my new notebook and the performance is very nice -- maybe not an SSD, but Linux loads quickly and programs start quickly.

Cons: None so far.

Pros: I'm not sure how the unit behaved stock, but I upgraded the RAM to 8GB and the HD to a 7200RPM drive, installed Linux Mint (all hardware works at install without any additional configuration or drivers) and the performance is excellent. Very responsive, quick boot time, etc. Even with the upgrades, still an excellent value for the performance. I used it to replace a netbook running Linux Mint and the difference is very significant.

Cons: None that I've found.
