Corsair TX 750M Issue or P8 Z68 V-Pro issue?

post #1 of 5
Thread Starter 
Hi guys,

just gonna cut to the chase - ASUS AI suite has been reporting a 3.3V rail at 2.896V and a few google searches later I found out it was either buggy software or a bad motherboard sensor.

So I ignored and carried on. So recently my PC has start shutting itself down and restarting with a message saying that ASUS A?nti Suge has been engaged because of a faulty power supply. The thing is, this power supply is one I bought recently to replace a damaged one i had before so it is practically brand new.

I can't offer any testing info as yet because I am just typing this as fast as I can while I still have a running machine and it is 1AM here and I have no tester.

Just tell me what should I do if the problem is A - Power Supply or B - Motherboard

Bear in mind I don't live in the US and I cannot RMA anything (it will be almost impossible)

Are power supply rails fixable?

Software reading is not accurate, you need to test with a multimeter. I doubt the PSU is going bad, probably Asus utility is misreading it and forcing a shutdown or restart. Uninstall the Asus utility and see if the problem persists. If it doesn't then the PSU is fine.

Run Memtest too, issues with the 3.3v rail are sometimes reported when bad memory is involved.

Ok, so an update, I shut my system down after I made that initial post and after a while when i started it up again, the BIOS (which had reported the 3.3V in the red) was in the 'safe' range of around 3.04V

CPUID HWMonitor is reporting similar voltages for the 3.3V rail and no more errors on AI Suite.

Left my PC on overnight and returned to find AI Suite reporting my motherboard temp at 123 degrees C and my 5V rail at 0.0V

Uninstalled.

The thing is though, the BIOS and HWMonitor was reporting the 3.3V undervolting issue (not just AI Suite) so I'm not entirely sure if I am out of the woods until I take a multimeter to the PSU.

It all seems fine for now.

AI Suite gave me nothing but problems. I wouldn't be surprised if everything if fine.
