Problem: The PC was build around November 2016, ran smoothly the first 1-2 months. PC will shutdown, it can happen anytime. What will happen is the computer will shutdown, then it will stay shut off. I then go ahead and press the on button on the front panel to turn it on, then it will enter a bootloop. The boot loop looks like the kind many other people on these forums are having. The PC will start for 1 second, then shut off for about 3 seconds. This will repeat until I am "lucky" and it will start by telling me it was ASUS anti surge or just a plain restart with no error codes. But most of the time I got to flip the on/off switch on the PSU and take out the 24-pin power cable for the motherboard before it's fixed. So basically, same story as many others on these forums.
System specs:
Intel Core i7-6700K
ASUS ROG Maximus VIII Formula, S-1151
ASUS GeForce GTX 1080 ROG Strix Gaming
Corsair Vengeance LPX DDR4 2666MHz 16GB
Corsair AX 860i, 860W PSU
Crucial® MX300 750GB 2.5" SSD
WD Desktop Blue 3TB 3.5"
Corsair Obsidian 750D Big Tower
What I've tried:
-Rebuilding the PC because I thought there might be a short circuit with a standoff or somthing. Nothing!
-Testing motherboard, CPU and PSU to see if I can get up bios.
-Testing Mobo, CPU, PSU and 1 brick of RAM.
-Tried all of the RAM. 1 by 1.
-Ran MemTest86.
-Changing PCI slot for my GPU.
-Checking temps on all components.
-Rebuild the computer, 2nd time. Checking everything is snug and perfect.
-Changing all the cables with new ones.
-Send in a RMA for my PSU, wicth was tested OK with a stress test that lasted 60+ hours running PassMark, BurnInTest og Heaven benchmark.
-Rebuild the computer again for the 3rd time. ran alot of different stress tests. This time there is no shutdown for 2 months, then shutdowns again.
-Did some testing with support on the phone. Showed him this forum with all the posts about faulty PSUs. Send in a complaint to the seller, waiting for answer.
I dunno what I expect by posting this, mostly for awareness and for others to see the problem. Ofcourse IF you know anything I dont please feel free to help me :)
