PSU shutdown

[Gio2vanni86]

I had posted this on a different site "TH" and didn't get any responds. I think people on there hate me. Been meaning to sign up to this site hopefully nobody hates me just by this posting. Going to paste all of it an hopefully someone can give me some input here.

For the last week and a half I've had my new PC built, and it was running fine until last night it all of suddenly shutdown and powered itself back on in about 2-3 seconds. When it turns back on i get this message "Power supply surges detected during previous power on. Asus Anti-surge triggered to protect system from unstable power supply unit! Press F1 to Run setup" Of course i did that and it worked, i ran BF3 for about 20-30 mins and nothing happened. Today when i powered it back up this time it powered down after 5-10 mins of just browsing the web with that same message.

PC Spec:
Intel i5 3570k
Noctua NH-D14 Cooler
ASUS P8Z77-V Deluxe
Geforce 580GTX
G.Skill 2x8GB's
Sound blaster
Antec DF-85
Samsung 830 64GB SSD
OCZ Vertex 4 256GB SSD
2x 3TB seagate HDD's
Cooler Master silent pro gold 1200 watts

I looked up online and just wanted some Hardforum input since I'm little skeptical. As of now i have an open RMA request going in to Cooler Master waiting to be verified. My problem is could it be a faulty PSU? The system itself as is, is only taking about 600 Watts which i know the PSU is complete Overkill and yes i know I'm stupid. Just seems strange to me, i have a few options i can do but i don't have much confidence in doing them, there as follows.

1. Disable Anti-surge in bios.
2. Switch PSU for working Cooler master 1000 watts 80 Plus(from old build but works)
3. RMA PSU
4. Faulty Motherboard and or memory.

I have a feeling its the PSU, i checked the wires and everything is connected correctly i just don't see why this would happen after a whole week of it solidly working. The CPU is OC'd a bit but not much, its at 3.8 since i set the memory XMP to 1600 it automatically clocked the CPU up. My gpu is a bit OC'd as well but i doubt that would do it. Any feedback, opinions? I looked in the bios and all the Voltage readings looked good, better then my old 1000 watts.

Just a small update on the matter.

My Bios readings are as follows:
+3.3 "3.344v"
+5 "5.000v"
+12 "12.096v"

When i got into windows i checked the AI suite and i got different readings on the +12.
+3.3 "3.344v"
+5 "5.000v"
+ 12 11.616/11.424/11.328/11.808/11.232/11.520/11.040/11.904/10.944

I was writing them down as they appeared within a minutes time. Now i don't trust software often but i can just assume its a faulty +12 on my PSU. Am i right?

Hopefully someone can help me, thanks in advance if you do. Right now waiting for frys to open up going to try and exchange it although the 30 days is long over like months ago they still sale that PSU and hopefully they will exchange it for me. But i am not certain so i hope maybe someone can give me some feedback if it is the PSU. Thanks again.

Have you tried setting everything to stock?
Maybe run prime and see what temps you get on everything you can, maybe something is getting hot?
Check all connections in the PC and if you have a spare system, check the PS in that one.
If you have a multimeter check the +12 voltage with it so you get an accurate reading.

I agree with the multimeter suggestion. Also, if your connector isn't getting propper contact, you might get alot for voltage drop. That would certainly trigger your surge protection aswell. I'd verify all the connections on the ATX plug and the EPS plug.

I just wanted to thank you both for replying I had a friend come over and we had gone to fry's and i picked up another PSU unit which was a Raidmax 850AE Gold rated. I plugged it all in and maybe i had bad luck but that PSU got into windows and about 30 seconds in it completely turned off without rebooting on as my previous PSU had done. After serval attempts at trying to power it on and even reset the CMOS it didn't turn on and only span the fans a bit. Maybe it was a sign. So scared out of my mind i raced to put my other PSU in the Cooler master which it booted and ran perfectly fine and volts in bios were higher then i had posted before and the AI suite also reported the same volts as the bios and did not fluctuate at all. My friend after examining my wire setup with the cable management i had saw something i over viewed which he being much more an electrical person then myself saw something i didn't see(some times you need another set of eyes), i had some extensions added to the 24pin and 8pin to extend the cables through the back of the case to provide a much cleaner look inside the case, but the cables bent in a way where i guess it was triggering a loss in volts. He said i was pinching the wires. As of right now the system is running and volts are stable and i'm almost quite sure it was that. Many thanks for the replies i appreciate it, i salute you guys. Cheers! Back to BF3
