PSU going bad?

[fatphatboy88]

Lately I have been having issues with my computer randomly restarting on its own. Every time this happens I get a warning about "Power supply surges detected during the previous power on."

My system is an Asus Z97-P, G3258 @4.7 ghz, 8gb of 1833mhz Corsair Vengeance, EVGA GTX 960 SSC, 240gb Kingston V300 SSD, Seagate 1tb HDD, Corsair CX600M and Corsair H100 water cooler.

Everything ran flawless for about 6 months until I added the GTX 960. It ran for about two weeks over clocked to 1515mhz without a problem, then the restarting occurred. Ive tried disabling the power surge protection in the BIOS and it still happens. Ive tried having the PC connected directly to the wall and on a surge protector. It still happens either way. The PSU should be able to handle my system no problem.

So is my PSU toast or is there something else I can do that I haven't tried yet? The PSU should still be under warranty but I would prefer to upgrade to a better one if this one is toast.

I personally have no experience in dying PSU's but I have shorted one.. killing the whole machine...
not a fun experience.

There's the possibility of it going ape shit powersurging frenzy and fry all the devices connected to it, so it would be best if you RMA'ed the Power supply, Corsair is fabulous at RMA'ing

if you're wanting to upgrade, buy a better PSU. Then either have the RMA'ed PSU as a backup or sell it.

Edit:

but you should try and remove/change the GPU and boot, Reseat your Ram in different order. reseat the power cables properly. old bad harddrive?
it might be a bad part somewhere making the PSU short.
best way of testing is with another PSU if you have one laying around or borrow one.

I hear Asus motherboards are notorious for having false power surge reports.

I would be more concerned with whats making your pc reboot by itself. disable all overclocks for a week and see what happens? just a thought
I also feel like the only power surges a motherboard could detect would be power drawn from the board itself? I myself don't have anything drawing power from my board, but lots of people use power from the fan headers on boards. Is your water cooling drawing power from the board? Kinda like overloading an outlet in a house some times. Is it possible something drawing power form a fan header is possibly drawing to much power? I get a usb power surge warning every once in a while but its never crashed my pc or caused a restart....just throwing ideas out there for what its worth

Yeahhh, 4.7 sounds a little aggressive....

First power surge protection does not do any actual protection. It is only a warning alarm. And not for high currents (a surge). It warns of a low voltage (a sag or brownout) that only occurs on electronics side of the PSU.

Normal is for voltages to drop well below what electronics need. Electronics still keep working. Also normal is for a volt meter on a motherboard to be uncalibrated. Therefore report a low voltage that does not exist. But in your case, a low voltage (probably constantly) is being detected intermittently.

Nobody can say with certainty what causes your problem until some numbers are obtained. That requires a meter, some requested instructions, and about one minute of labor. Without numbers, then every reply is only speculation. "It could be" or "maybe try ..."

How would I test it with a DMM? Is there a write up some where on which rails to test or points on the motherboard?

I dont run it at 4.7ghz all the time. Normally its at 4.5ghz @1.255v running under 55C at full load.

Right now I have everything set back to stock settings except for the XMP for the ram. Going to run it this way for a week or two to see if it still happens.

its pretty rare to test voltage on points of the mb especially if your just troubleshooting as to weather your power supply is putting out correct voltage. fire up something like furmark and put your gpu and cpu at full throttle and break out a free molex connector and test black to red and black to yellow.

The other voltage rails in our pc are 100 times harder to test and are not as relevant anyway. I just trust what software tells me in that regard since even if those other rails were off it's more likely a mb malfunction vs your power supply assuming your 12volt and 5volt rails are with in spec (+/- 10%) most....closer the better

Pictures of using a DMM do not provide all useful information. And no, most DMM web instructions provide insufficient information - do not measure all appropriate numbers. Even a +/-10% tolerance is incorrect, 12 and 5 volts can measure close and still report a failure. All rails are easilyl measured.

If instructions call for a measurement with a meter, then even voltage measuring software is insufficient.

Again, three required items are a digital meter, some requested instructions, and about one minute of labor. Asking what to do was 'after' that post said how it is done.

These are forums bud....if people need/wan't more info...trust me they will ask
The op asked how to check a power supply and i believe i gave fairly correct info

Your post above just hits me as rude, and full of bullshit. Try and be a little more mature and word your post a little different because honestly.... your not providing any useful information
And lastly its more than likely not even anything wrong with his power supply....Im sure op will post back if he still has issue after dropping his overclocks
