I just want to be sure that this is ok.

My parts: http://pcpartpicker.com/user/topguythegreat/saved/hLMwrH

After updating my UEFI Bios, this seemed to start occuring. It seems to randomly occur at different times, and only happened 2 times. It can happen while just simply being idle, or just browsing the internet. I have a feeling that it is because my CPU usage is getting abnormally high, and sending a increased amount of power to it, activating this Anti-Surge. I doubt it is any type of PSU problem, but if it is please let me know.

I also looked online, and some people say to turn Anti-Surge off. Should I? This system is about a month or so old.

Power line surges and power supply output surges are two completely separate issues.

Surges on the power supply's input when pulling the plug and re-plugging or toggling the hard-switch are caused by the inrush current when the PSU's input filter capacitors get charged from empty and are a normal part of flipping the PSU's hard-switch on and off. PSUs should have absolutely no trouble handling that. Other surges on the input side are caused by large appliances switching on/off, power grid issues, lightning strikes, etc.

Power supply output surges...

Anti-Surge monitors PSU voltages and shuts down the PSU if it gets out of bounds to hopefully prevent damage to your components. If it starts tripping, there is a high probability you have some power-related issue.

I had an anti-surge trip on my computer a few weeks ago. After investigation, I found that its PSU was unusually warm and it turned out the case's bottom filter was packed. I knew I would hate that dedicated PSU filter one day. (Well, I already did not like it from the start due to its inconvenient location.)

I have a Surge Protector connected to the wall. Should I turn the Surge Protector off? I heard that it protects against Surges on the motherboard even without anti-surge on. Will the surge protector in the wall prevent surges too?

Anti-Surge on the motherboard has very little to do with your surge suppressor power bar or UPS unless anti-surge events happen to coincide with power line surges but then that would point to a not-so-good PSU.

The power bar / UPS surge suppression deals with AC mains power surges while Anti-Surge deals with surges on the power supply's low-voltage outputs.

I will like to ask also. Like for example say if I was to pull the plug on my computer while it was running a game, and then plug it back in again it would cause a power surge right? As if so, is this kind of spike high enough to damage the PSU or any other components in the PC ? Well I have heard of build in surge protection in modern PSUs but are they sufficient to protect against these kinds of surges? And what about Asus antisurge is it enough protection against a power surge in this situation as well ?

@InvalidError and what does it mean when you said Anti-surge deals with surges on the low voltage outputs? Sorry that's a lot if questions but I really am curious to know

PSUs should have absolutely no trouble handling that. Other surges on the input side are caused by large appliances switching on/off, power grid issues, lightning strikes, etc.

Power supply output surges are caused by bad caps, output regulation control loop stability issues, excessively noisy loads, wiring impedance, under-sized caps, slow input/output transient response, etc.

Both sides of the PSU may share the term "surge" but they are completely different and generally unrelated things on completely different scales: a power-line surge can be tens, hundreds or even thousands of volts but on a PC PSU's outputs, even a single volt would be considered a significant surge.

Damn I wish I were as experienced about electronics as you do. But I seem to be a complete noob no matter how many articles I read haha. Anyway thanks a lot for taking the time to explain this it just opened up my eyes some. Cheerz
