So is it the PSU?

I am getting complete shutdown of my computer here:

System2: Core i7 4770K @ 4.3 GHz, ASUS Maximus VI Formula,16 GB Vengence 1866, MSI R9 290X in Crossfire, watercooled by Heatkiller 3.0 and XSPC, Custom Corsair 600T, power by SeasonicX-1050, Dell 2410s in EyeFinity.

I can run the computer all day long with no problem.
I can run Memtest with no problem.
I can run GPU benchmarks, such as Heaven, with no problem.
The CPU runs against Intel Burn and AIDA testing just fine.

When I try to run either Metro: lastLight Redux or Crysis 3, the minute I get into the game, the computer just shuts off like somebody unplugged it. I have to power the PSU off to get the system to restart.

I've run Kill-o-watt on the system and it's pulling about 700W under full load.

The Seasonic PSU is about a year old.

My suspicion is the PSU is faulty. I have a spare 850W PSU I'm going to try, but I'm short on other ideas.
 
You shouldn't even ask for other opinions!! Since you have a spare PSU, try it out.
I agree with you that most likely the PSU is faulty.

P.S. Do you have a UPS? If yes, can it provide the maximum of 700 watt that your system needs at full load? If its capacity is near 700 watt, then the UPS may also be suspect.

No UPS.

Yeah. I realize that I know the right answer, but if someone else has a different suggestion, before I tear the whole thing apart and mess up all my cable routing, it would be appreciated.

I'm pretty sure the PSU is the problem....but you never know.....:D
 
High probability that the PSU is faulty. Use the other PSU to swap out the SeaSonic X-1050 and either confirm or eliminate the SeaSonic PSU as being faulty.

As an aside. My SeaSonic X-660 PSU is only two years old, only loaded to around 250W, but it is suspected of failing or being faulty also! Surprised and disappointed that these high quality PSU's appear to be failing/faulty after little use!?
 
I jumped a second PSU to the Seasonic, disconnected my second 290X and connected it to the second PSU and I have no problems now. Not a single crash.

I have already looked at the draw on the full unit at load and it is nowhere near what I would expect to trip the overload on the PSU. My wall draw at load measured by my Kill-a-Watt is 700W.

So, I think there is something wrong with my PSU, sadly......it's just 12 months old and the X series from Seasonic is touted to be some of the best around.

All my other components test out fine, 100% good.

Sent an RMA request to Seasonic, all done on line, no problem. Going to send the unit back as soon as I can find a solid 1050W replacement.....I think I'm going to try a Corsair unit and then sell the RMA unit when it comes back.:D

Does it happen with any game that is 3d? Or just the ones specified above? If its JUST these games, then it could be software related. If its all 3d games, likely it is hardware related. I am guessing PSU...

**edit**

Looks like you found the issue. Even excellent hardware fails sometimes.
 
QC is never 100%. And the more popular the product, the higher the number of failures, though the failure rate may be extremely low.
