Question: ASUS Anti-Surge Issue, already changed PSU and still no dice

I've tried looking through as many threads as I could find on TH regarding this and many of them speak to a faulty power supply, but I'm not sure that applies here so I was hoping to see if someone might have an answer for my specific situation. Thank you for reading!

The Specs:

Motherboard: Asus PZ877-V Deluxe
CPU: Intel Core i7-2700K Quad-Core Processor 3.5 GHz
Video Card: GTX 660 Ti Boost
Power Supply: Thermaltake 600w
RAM: 16gb (Corsair Vengeance maybe? Don't remember exactly)
CPU Cooling: Corsair Hydro H80 Series
Misc. Cooling: Two fans that make my computer sound like it's prepping for launch
OS HD: SanDisk 128gb SSD
Storage HD: WD 1TB HDD

The Situation:
Recently I built gaming rigs for my fiancee and myself, within the two weeks or so. They're very closely related systems with mine having only slightly better specs than hers (Hers has a GTX650, mine has the 660 Ti Boost for example) as she only really plays Minecraft. However, her computer seems to be the only one that wants to work right because after a few hours of playing any games, my computer randomly shuts down with the infamous Asus anti-surge message on reboot saying the system was shut down to protect it from a surge. Well, this happened a handful of times over a week or so and I started researching the issue and realized that the 500w PSU I'd purchased (the same model/output is working fine in my fiancee's rig) might be the culprit so I went and replaced it with a Thermaltake 600w PSU last night both to use a better brand and to up the output in case I'd gotten too close to the power demands of the system. Figuring there's a possibility that it was a heat issue with the GPU, since the Corsair Hydro 80 CPU cooler seems to be working fine, I hooked up a couple fans and now my PC sounds like a harrier jet so I don't think it's a heat issue either. Finally, I've also got my entire system hooked up to an APC power strip that is brand new so I'm not thinking it's an issue there. I can't figure this out for the life of me and I've checked all my connections just to be sure, especially since I had to reinstall the PSU so I don't think anything is just loose and hanging out. The case is also on top of a desk in a well ventilated area so it's not a dust thing, especially only being a couple weeks old.

What I've Tried Already:
1. Changing out the PSU for a better brand and output
2. Checking all the connections
3. About an hour of digging through threads
4. New APC power strip
5. Heavily drinking and begging the computer not to explode

Possible Culprits:
1. Motherboard might have a capacitor issue? That would suck because it's brand new too
2. Both PSUs are janky?
3. ASUS added a "feature" that is hyper-sensitive and should be disabled?
4. Gremlins?
5. Both computers are in the same room of the house, so it might be an issue with trying to pull too much on the circuit with two PCs and four monitors, but if that were the case I feel like her box would be experiencing the same issue, especially since she doesn't have a fancy power strip.

The problem is not quantity but quality: your system as-described should work fine even on a 350W PSU if you had a HIGH-quality PSU.

What is the exact PSU model? Most PSU vendors have more than one unit under their belt at any given power rating and performance can be substantially different between PSUs with similar sticker ratings.

Of course, the motherboard's protection circuitry having excessively strict tolerances is also a possibility as you said.

I was debating doing that, but I want to keep that as a last resort if I just can't figure out the culprit. I appreciate the consideration though and it makes me feel better about thinking that it was probably being hyper-finicky.



I don't have the box with me but I believe it was their mainstream TR-600 model. I picked it up because it was late and I didn't have many options in front of me but I knew the brand was better than what I'd initially succumbed to when I was buying all the components and looking for a sale.




Awesome answer. I appreciate your help on the issue at hand!

 


For what it's worth I had to turn the anti-surge protection off on my PC as well. I have a Seasonic X-1250 which is one of the best PSUs out there. It's just a very finicky implementation on the part of Asus

Yeah, I appreciate the reassurance. It might be what I wind up having to do simply because, based on reading half a dozen threads where it says that this feature is super fickle, it seems like it might be the source of my headaches. My logic behind this is this:

- The odds of two brand-new, faulty PSUs (even if they aren't top of the line) is very low. Low enough that it's a risk I'm willing to accept rather than continuously buying new and increasingly more expensive power supplies.

- It doesn't seem like a circuit issue within the room because everything else is running fine without dimming or failures

- Cooling isn't an issue, neither is it an issue that power is getting TO the components. Nor is there an issue with connections as everything is seated and all the plugs are securely connected

It's not 100% sound logic because it doesn't take into account all the angles but if I can't figure something out through TH then I'm just going to throw caution to the wind and disable it. I too like to live dangerously.

The motherboard's "anti-surge" protection has nothing to do with building wiring. What it does is monitor the PSU's output as seen by the board and apply its own under/over-voltage protections on top of whatever the PSU may also have, the idea being that should the PSU start going bad and fail to shut itself down, the motherboard will (hopefully) do it before other components get damaged.

Ideally, before disabling that, you should at least check that the PSU's output voltages are safely within tolerances at both idle and full system load.

I'll do some research and see if I can can match up the mobo tolerances with the PSUs I've bought just to make sure they synch. I can't imagine that the tolerance window would be so narrow that not one, but two different PSUs trigger a fault warning and shutdown but I could definitely be wrong. Thank you for the direction, I'm going to spend some time looking into it now.
