So far so good, except for rebate 1/25/2016 2:13:57 PM

Pros: Lots of useful connections.

Cons: Seems good so far. A bit on the loud side, but not bad.

** Rebate web address does not exist (host not found, checked for typos, can't get there from standard main site), so can't get my MIR money. Lose two eggs for that.

Pros: Has more than enough wires to hook up to anything and everything you're going to need inside your computer and each wire was clearly labeled. Works exactly as it's supposed to and haven't had any power issues in the 4-5 months since I built my computer. If you need to go with a gold certified PSU for your build, I would recommend this one.

Cons: Had so many wires it was difficult to keep some of them out of the way, but my husband was the one who put my computer together so it might just have been his problem. And I only mention this since I have to put a con.

Overall Review: This item was shipped from out of the country and took about a week or so to get here. But I knew this going in. It came well in the time frame.
