Faulty PSU

Within the last two weeks, my system has been randomly restarting on me. Sometimes it's within 5 minutes of restarting the last time, and sometimes it's hours later with an average of probably twice a day. It's not logged in event viewer as an error or anything. I haven't changed anything about my system in months, and I haven't changed anything to do with the PSU in a year. I replaced my Corsair HX850 with an XFX550, and I've since not had any restarts in several days.

Obviously this points to a faulty PSU. My HX850 is only about 3.5 years old, and I would like RMA it. However, I'm always nervous corsair is going to test it and send it back saying nothing's wrong. Since it's a random event, they may not be able to repeat it.

1) Does anyone think it could be anything else besides the PSU?
2) How successful have you been with Corsair RMAs?
 
Corsair its well known for it's great customer support and amazing RMA Politics, so go and RMA it you will have a good experience. however you can do few test yourself before send the unit like test the voltages under loads with a multimeter to see how it behave.
 
If swapping the component fixes the issue, 99% of the time the component will be the culprit.

Why would you RAM the PSU when it's not in your system?

And IF a PSU is broken, usually never boots up your entire system, I've had two PSU failures, one was a DOA and the 2nd one got to a point that I would hit the power button and nothing would happen, but it never game me reboot issues.

I had my PC P&C Silencer making a hissing sound when I put it on my new Haswell rig but the sound stopped after putting the system under heavy load but at idle it wasn't working, so I had to buy a Haswell ready PSU. Put the Silencer back in the old system and works flawlessly.
So, I don't think it's PSU related, could be RAM or CPU or the motherboard.

I think you misread my post? I don't understand what you mean with the first comment. Did you mean RMA? I took the HX850 out to test the system with a known good PSU to see if the behavior persists, and it does not. The two examples you've given are exactly that - just examples. Just because two times it's had a specific failure mode doesn't mean it's restricted to that behavior.

Thanks everyone else for your feedback. The voltages look ok with HX850 when it's not restarting. It seems like it might be a specific rail that's current limiting when it's not supposed to and causing the shutdown.
 
I'm pretty sure they won't send it back just because it worked with a PC they had. They probably know where the important test points are and they've seen so much of those they ought to know where to look.
