I have just built my new computer with the specs listed below.

ASUS A88X-plus motherboard
A10 6800K CPU
GTX 770 Zotac amp edition
2x4 1600 RAM ADATA XPG 1.0V
1TB Hard drive 7200 Seagate
With a 600 watt PSU cant find the brand name I will post when found

I sit here and play games for awhile about an hour or two and sometime in between that my computer just shuts off and reboots with an error saying ASUS has detected a power surge to help prevent further damage to the system the system has restarted. So I did some Scooby doo investigating and found that everyone was saying that ASUS mother boards come with a power surge protector on them and for people to turn it off. So I did, well tonight again I was playing for a couple hours and bam it happen again but this time no startup warning on bios bootup.

if you really do have a non-branded power supply....you are putting your whole system at risk(and I mean serious).You could use cheap ram,cheap motherboard,cheap cpu even ,but dont use cheap psu ever......its like sitting in a coal mine without a helmet,seems safe most of the time until the shit hits the fans.

But if thats not the case than is that happening only while gaming?.....see if the game is running in windowed mode turn windows hibernation off........see if you have overclocked something.....go down to stock clocks..and see if the problem persists

Anti-surge tries to shut down your PC before your components get damaged or data gets corrupted by bad power. Turning it off may "solve" the rebooting in some cases but could silently cause more serious issues to pop up later.

Since you still get reboots even with anti-surge disabled, it means something else is having issues and the default suspect in those cases is the PSU.

The last time I had issues with anti-surge on one of my PCs, it was caused by a clogged PSU air filter.

I have everything on low settings along with disabling some of the fans. I also have pics of data showing what my CPU and GPU are doing when they are being pushed to the limit but I don't know how to post a pic to this website

When PSUs start going bad, at first you get reboots while under load, then you start getting reboots for no apparent reason and eventually the PC simply won't even finish booting at all.

In some cases, the PSU may go unstable and destroy components. You want to repair or replace your PSU before it reaches that stage.

Quality vs Quantity.

If you have a crap-quality PSU, quantity is meaningless.

For your setup, even 450W PSU would be enough - as long as it is a high-quality one. But 550W is where most reasonably priced quality units start at.

Surge can mean high voltage (thousands of volts). Excessive current. Too much air. Slightly high voltage. Insufficient current. Or in your case, a slightly low voltage. Determining what is wrong from a subjective expression (without numbers) is why some will recommend many erroneous or completely unrelated solutions.

Useful replies made themselves obvious. For example, most computers do not even consume 300 watts. A 450 watt supply is typically more than enough. And wattage (quanity) does not define quality.

Your motherboard has identified an anomaly. Two possible solutions. Get some instructions and one minute of labor using a digital meter to discover what is defective and how to fix it completely the first time. And by disconnecting no wires or parts. Numbers mean that anomaly and an immediate solution can be provided here,

Otherwise shotgun. Just replace good parts until something works. Often a PSU is the first thing replaced. However that may only cure a symptom. Without a meter, nobody can say if a defect has been eliminated. Even a defective PSU can still boot and run a computer. Anomaly may reoccur later as it gets worse.

Your choice. Identify a defect before fixing it. Or just start replacing parts. Either way, a motherboard has reported a problem that will create intermittent crashes today and will create hard failures (without other hardware damage) when the system is warmer or older.

Surge in the context of Asus Anti-Surge means that voltage monitoring on the motherboard detected an out-of-bounds voltage on one of the power supply outputs and the threshold for that is maybe two volts out of spec, likely less.

You will not necessarily see what causes anti-surge to trip with a multimeter (unless you have a ~$1000 model that can do hundreds of measurements per second) since it can be triggered by millisecond-scale transients. To see those, you would need an oscilloscope.

I did not know that. Since we have used meters successfully even years before PCs existed. Yes a meter does not measure millisecond spikes. But then it need not. I could post a long and technical discussion on why. But that would only make eyes glaze over.

Bottom line: even a 5 buck meter from Harbor Freight or a seven quid meter from Maplin will provide numbers that identify the defect. No oscilloscope or $1000 RMS meter necessary. We did this even 35 years ago. Resulting numbers are sufficient to immediately identify what is defective without speculation.

Bottom line: two solutions are defined. Either identify a defect and then replace that one part. With numbers that make obvious that a defect has been eliminated. Or just replace good parts until something works. And hope that did not only cure a symptom. Meter provides numbers for a definitive answer; no more 'it could be' answers.

Only if it is a DC voltage issue. If it is a transient response issue, a meter is not going to show you anything useful.

I have two old power supplies sitting in my workshop right now that "work fine" as far as far as my multimeter can tell but cannot boot my PCs. I have taken a few blind shots at repairing them, exhausted the obvious options such as re-capping and now I am simply waiting for the next occasion I might have to take a look using a scope to find out exactly what is happening with them.

Essential is to not disconnect any wires. Not put a PSU on the bench. And use some well proven techniques that define the entire power system - not just a PSU.

Meter cannot identify any specific internal part as defective. And need not. Since a meter most only identify what subsystem is defective. And identify when that defect has been cured. Once any PSU wire is disconnected, then a defective PSU can appear good. Again, best technique for obtaining a definitive reply is instructions, one minute labor, and numbers from that meter.

If you are chasing a transient response issue, a multimeter is not going to help you regardless of whether you are trying to troubleshoot the PSU alone or in-system - transients, noise, ripple, overshoots, ringing, control loop phase margin and tons of other issues are often much too fast to be detected by affordable multimeters.

With a multimeter, you can waste hours trying to chase transient and intermittent issues without finding anything obvious but with an oscilloscope, you hook it up, look at the waveforms and may get your answer before even trying to reproduce the macroscopic issue.

You keep saying I cannot do what is done in a minute and has been done successfully for generations. But then your post also demonstrates insufficient grasp of why a meter is so definitive and useful. You are arguing about things I agree with, that are irrelevant to the problem, and that are irrelevant to the OP.

Best way to obtain assistance from the fewer who know this stuff is to request instructions, one minute of labor, and report numbers from that meter. A task so simple that a 13 year old can even do it. What follows is an answer without any doubts or speculation.

Why have we been doing for decades what you say is impossible?
