Just FWIW, this seems to be a recurring issue with the AX1200i. I bought five of them about two years ago, and had 100% of them fail in this manner in one year or less. I actually replaced the unit in my main desktop with the TX750 it originally replaced, and it's running fine to this day. The four I used at work died one by one between 2 and 8 months of life. Those failures caused a business policy that Corsair power supplies were not authorized and explicitly forbidden. Honestly, I'd recommend saving yourself some time and grief, buy a different PSU, and throw the AX1200i away. Don't even bother RMAing, your replacement will end up dying the same way, maybe right away, maybe in a year or two, maybe letting the magic smoke out of some of your hardware when it does (Though I will agree that none of the copious reports show that, simply a variation on "it turned off on it's own and now turns off and on over and over in a loop, and self-test fails"). A few people have said things like "This is very rare" or "the odds against this are astronomical", but if you search Google you will see great numbers of reports with the same symptoms. The AX1200i works for anywhere from 0 minutes to just over a year, and then it powers off unexpectedly. It then progresses to it happening more and more often, and then it will fail entirely, causing a boot loop and various self-test light problems. This is not an isolated incident, I cannot locate anyone with an AX1200i that has been working for much over a single year. I am serious, and not exaggerating. My sample size is only about 100 people around the world, but *EVERY ONE* has had their PSU fail in a similar way. A report from 2012, along with an absurd number of failed RMA replacements; http://forum.corsair.com/v3/showthread.php?t=112526 A report from 2015; Another 2015; http://forum.corsair.com/forums/showthread.php?t=137874 Here's two guys in one thread with this issue from 2016; https://forums.tomshardware.com/threads/consistent-problems-with-ax1200i-platinum-power-supply.2813875/ Another 2016; https://www.bleepingcomputer.com/forums/t/618990/pc-wont-turn-on-fans-spin-for-1-sec/page-2 And I replaced my personal AX1200i with the TX750 it was supposed to replace in late 2017. I purchased it October 22, 2016. The TX750 was purchased in 2011 if I recall correctly, and is in use to this day. To be clear, I'm not saying that 100% of the AX1200i supplies in the world are bad. That's clearly not the case. What I am saying is that a statistically significant number of AX1200i units are failing in the same or very similar ways, and Corsair has had a great number "returned for analysis" and the only solution ever offered is "open an RMA and replace the supply". Did Corsair ever figure out the issue???
