Input: Ordered this PSU in March of 2015 and for 5 months it worked as expected.  In August 2015 I began to find that my tower had shut off (lost power) overnight.  I suspected the PSU, but plugged the tower into a different UPS just to clear the possibility of an external issue first.  The tower continued to shut off at random times.  Eventually it got to the point that the tower would shut off within minutes of being turned on.<br /><br />The fan wasn't coming on with startup, but that isn't unusual for this PSU since it employs an &#34;on demand&#34; fan, however the PSU felt cool to the touch after each failure so I doubted that it was overheating.  Rail voltages were within tolerances so it wasn't being shut down by a watchdog circuit, unless the watchdog was faulty.<br /><br />I swapped out the PSU with an old BFG 500 watt that I had on the shelves and the tower once again ran stable, not shutting down even after several days.  With the culprit almost certainly being the RM650, I called Corsair Tech Support.  My wait time wasn't overly long and the tech walked me through the steps that I had already completed before he reached the same conclusion I had, namely that the PSU was faulty.  He recommended that I use the Corsair Web site to RMA the unit, which I did.  I just shipped the PSU, so I'll update as the process moves along.<br /><br />I was going to 3 star the PSU for now, since it did fail on me in a very short time, but I don't like paying for shipping a heavy PSU back to the manufacturer when it failed through no fault of my own.  It's like paying an extra $21 for a working RM650.  So I subtracted a star for making me pay to ship the bad unit.

Failure in less than 6 months
