Pros: Stable power delivery.

Cons: Purchased back in July 2016. Dead in July 2017. First it started off by randomly shutting off and I had to unplug from my APC to get it powered back on, then it just completely died while troubleshooting. For $399 I was expecting better. Mine doesn't seem like a fluke either, its a very common problem with these units. Corsair already has the unit and I'm in the middle of the RMA process. So far their Customer Service has been good but I'm not here rating their Customer Service. I'm rating the AX1200i and if 0/5 was an option, that's what it should get.
