Hey all,

The past few days, my computer has been shutting off completely without warning. It shuts off like the power went out and doesn't tell me anything about it afterwards. I have been lowering the overclock on my i5 (from 4.5 to 4.4 to 4.3 and so on) until today I finally had to go back to 3.4 just to get it running.

Today was the first time I got a message.

Recently it has been after I was playing games, but before that, I could be doing anything and it would shut off.

The current voltages are:

3.3v: 3.0 (seems low)
5v: 5
12v: 11.9

Does this mean a bad PSU? I might take out the psu, clean everything up (since there is a little dust) and then plug everything back in after inspecting the PSU.

Is there anything I can check?

System Specs:

- i5-3570k
- Corsair h100i
- ASUS P8Z77-V Pro
- 16GB (4x4GB) Corsair Vengeance 1866 Mhz
- Samsung 840 Evo 500GB
- Seagate Barracuda 2TB 7200RPM
- Gigabyte G1 GTX 970
- Corsair TX850M

Thanks.

You could check with the next tool,see what voltages that gives,

download hwinfo32,
install and open it,
check "sensors-only",
click "run".

best thing would be using a multimeter though.

The psu has an under voltage protection so should turn of if voltages were to low,you could try and disable Asus Antisurge,but it would be your own risk. From what i know are they pretty much the only manufacturer that provides such a thing though.

If voltages are to low could you maybe look at Corsair and open a support ticket since the psu has a 5 year warranty. I guess you talk about this one,

I'm an idiot, I completely forgot to include the PSU specs.

Corsair TX850M

The computer seems to be running fine right now on 3.4 Ghz. Also, I heard that ASUS motherboards are kind of lacking in terms of sensors and readings, so even though it says 3.0, it may actually be 3.2-3.3. Is that true?

I was planning of getting some new components this summer anyways, so if I can survive on 3.4 Ghz (which won't be an issue) until then, I can get a new one.

This computer has been running on average 22-23 hours a day for the past 4.5 years, so I'm surprised the power supply has lasted this long in the first place. The only things I needed to replace were two Corsair fans.

you say you have the pc for 4.5 years so it's still within that 5 year warranty period.

I'll check out the support ticket, thanks.

As far as the multi-meter goes, do I just locate the two pins and test them on the connector? I've never done that before.
