Is my Corsair AX860 PSU Faulty?

[Lundh]

So about 8 months ago i bought a new rig, and one of the components was a Corsair AX860 PSU. And recently I've started having problems with the computer shutting down suddenly, with no warnings, no bluescreen or screen of any kind.

However this seems to happen at random, because it doesn't matter if the CPU/GPU is under 100% load in stresstest programs, or if i'm randomly browsing the web. It can happen whenever, regularly about once per three days. It has nothing to do with overheating, temps are regulated very well and never ever goes above 60C.

My specs are as follows:
2x GTX 970 MSI Gaming 4G in SLI
i7 4790K CPU
AX860 Corsair PSU
16GB DDR3 Corsair Vengeance
RoG Maximus VII Hero
2x 256 GB Samsung 850 EVO
Fractal Design R5 Stock Fan with a Noctua NH-D15 as CPU Cooler.

So is it my PSU that is faulty? Will i have to RMA it?

Thanks

First, make sure ALL power and data cables are connected properly.

Next, make sure the video cards and DIMM's are seated firmly.

If still have issues, then try another known working PSU, and/or try the AX860 PSU in another computer.

Most likely its the PSU dying or the Motherboard. Most other things will cause a blue screen. I would advise to try another power supply and see if that fixes the issue if. Worst case you can RMA it to corsair for a replacement. If the replacement does the same thing I would advise it is the motherboard.

It's bothersome to redo the entire cabling in the computer but if there is no other way.. Would also be really bothersome if it was the motherboard that was the culprit if i RMA the PSU. Will there be no bluescreen if the motherboard is the fault? What can be the fault in the motherboard to cause an issue like this?

I have made sure all cables are firm, and the DIMM's are seated correctly.

Over the years the only time I have seen a computer just shut down with no error or blue-screens usually means Motherboard or Psu. Sadly you need to trouble shoot the issues otherwise you will never know what is going wrong. The AX 860 should have a test switch on it unplug all of the cable and see if it gives you a green light. Its hard to tell sound like something is getting warm and shorting out after a random matter of time.

I will today and tomorrow work on some troubleshooting and see if i can't turn up the culprit then, i have a second rig but it has a non-modular power supply so will have to redo the entire cabling, sigh. Why do you hurt me so computer..

I'll report back if i find anything of use.
