Maximus V Extreme - Surge problem! Need some help and suggestions...

Level 7
Hey all!

I see that something like this has already been discussed, but I didn't find solution for the problem. First of all I want to say that my PC worked for 3 years without any issues, and suddenly it started to crash (multiple random restarts) few days ago with a message that Power surge was detected and that motherboard prevented bad PSU from damaging my components.

My rig:
CPU: i7 3770K
RAM: Corsair Dominator GT 4x4GB (2133MHz)
GPU: 2x EVGA GTX 680 Classified 4GB
Soundcard: ASUS Xonar STX
SSD: 2x INTEL series 520 128GB
HDD: WD 3TB green
PSU: Enermax Platimax 1000W

What I tried to do is next: I removed both GPUs, as well as soundcard and everything that was connected to USB ports, and finally I removed 2 RAM modules at a time, then other two... but problem persists. I also removed molex that was connected to the fan controller and 6 Noctua fans and cleaned dust from PSU and case. When I managed to start my computer and run HWmonitor it seems that all voltages are perfectly fine (BIOS reading is the same). No peeks or drops whatsoever. I even tried a different power plug and socket, but problem persists. So, all I have connected now are 24 and 8 pin CPU connectors from my PSU. I didn't try different PSU, because I don't have one, but I did reset BIOS and I still have a problem.

Could it be bad MB or PSU? I was able to stress my CPU and no surges were detested during that time, so I suspect MB or PSU, there is nothing else left I supose. Same thing happens while surge protection in BIOS is disabled...

The thing is that I don't want to buy new PSU if my MB is defect... did anyone else expirienced that Maximus V Extreme have some issues regarding this problem? Or do you guys have any idea what could it be?

All temperatures are fine as well and I didn't overclock anything.

Thank you in advance!

Hello Nietzsche

The maximus v extreme is an awesome motherboard I have that board too, with no other parts to test with it's a guessing game which one is causing the problem. You could try updating the bios then if that doesn't help, I will lean towards the psu with the power surge message.

Thank you four your reply!

I managed to isolate a problem and PSU was causing surges. I couldn't wait so i bought second hand PSU today and system is stable for 5 hours now. It is very sad though that PSU that was over 200 euro is starting to fail, although I am happy that my MB is ok. 🙂 Sending PSU for RMA tomorrow...

Thank you one more time and good luck.

You're welcome

Great to see you're back up and running in no time flat. The platimax looks to be a good psu, keep it in the box for a future spare. 🙂
