Faulty PSU again? (corsair CX600m)

Hey guys!

So, a couple of weeks ago I had a brand new PSU (Corsair CM600M) die on me. Burny smell, suddenly stopped working. I sent it back to the vendor, they tested it and replaced it (though it took them weeks to do so).

Once I got the replacement PSU, I installed it, and everything worked fine. Though there was a bit of an odd smell, it was nothing compared to the first one and since everything worked fine I assumed its all good.

Untill yesterday, when I walked into the room and once again smelled something funky. PC was still running fine, but I was a bit suspicious. So I check out the PSU, and thinking I see something odd I grab a flashlight and look through the grill thingy.

I can literally see the exposed "metal" bits of the wires, where to coating had melted off and burned. This on both the thick Brown wire and the thick Blue wire. Both burned and melted, quite near the point where the power cable attaches. There might be more but I cant see inside the PSU that well without removing the cover, and that'd remove warranty so I'm not doing that :) 

Naturally I removed the PSU from the rig instantly and it's being sent back as we speak.

Now my question is this:
Either:
A) Am I just plain unlucky and I just randomly hit two faulty PSU's?
B) Is there something else wrong? Could the problem be in the wall socket, or somewhere else?

I have to add that the wall socket looks, and smells fine, and is grounded. As does the power cable running from it to the PSU. All the burny parts are inside the PSU.

Thanks for any answers!

Probs the wall socket. I got the exact same PSU plugged into a surge protector plugged into another HUGE surge protector and nothing bad so far. The CX series is decent at best, with the modular ones (Yours and mines) being slightly better. Anyway, you could have still ended up with a bad one. Have you got another PSU to test on that wall socket for a while?

Unfortunately no, though at this moment my laptop is plugged into the same socket with nothing funny going on. To be honest I'm not even 100% sure the PSU is faulty, it just doesn't look right to me. Like the brown wire, where it is soldered to the on/off switch, is all blackened and melty. Which doesnt seem right to me, but then again, it has to connect to that switch somehow.

Try Seasonic , XFX made by Seasonic , Corsair but not CX series , or Antec.

This is what the CX600M should look like behind the AC receptacle & power switch:

Well, thats what it looks like except that on the right side of the picture, those brown and blue wires, are exposed at the point they are soldered for a good centimeter. As in, I can see the inside of the wire, with the brown and blue coating melted away and blackened. I kinda assume thats not supposed to be like that so I sent it back.

And like Blackbird said, I'm gonna ring them up tomorrow and see if I can get it replaced with an XFX (XFX PRO550W Core Edition) or a Silverstone (SilverStone ST50F-P). Because I'm tired of corsair parts giving out on me (also had 2 corsair memory sticks turn up faulty).

Melted insulation on the brown and blue AC wires to the PSU's primary side would indicate an extremely high power draw which is definitely abnormal.

The XFX is the better choice.

Well, I just ordered the XFX as a replacement, so we'll see how that works out. I also got my uncle (who's an electricien) to replace the wall socket and I put a surge protector in between that and the PSU. So fingers crossed there's no more burning :)
