Asus anti surge keeps triggering

[deathstreike125720]

Hi guys i recently have purchased a used psu its a thermaltake 750 gold W0116RU. I know it was a couple of years old but i bought it anyways. So after installing it my comp would randomly shut down, usually when i was playing a game and afterwards it says anti surge was triggered. I have no idea why this would be happening since 750 watts is more than enough for an r9 270x and i was only playing swtor. i coudl really use some help here thanks guys.

I don't know what you are going to find with a "meter" other than your +12V is at +12V, 5 is at +5V and 3.3 is at +3.3V. .

How to provide numbers for assistance from the fewer who know how the entire power system works:
Restore everything as when the computer worked. AC power cord connected to a receptacle. Computer not on. Set a digital meter to 20 VDC. Attach its black probe to the chassis.

Locate a purple wire (pin 9) from the PSU to where it attaches to the motherboard. Use a red probe to touch that wire inside a nylon connector that attaches to motherboard. If necessary, make that connection using a needle or paper clip. It should read somewhere around 5 volts. Record that number to three digits.

Next, do same with a green wire (pin 16). Then press computer's Power On button. Monitor how meter changes and what it eventually settles to. First number should be something well above 2.6. Second number should be something near to zero, Actual numbers and time to change (behavior) are relevant.

Repeat same to a gray wire (pin 8). Note a higher starting voltage, a lower final voltage, and its behavior. Report those three digit numbers and behavior.

Setup computer to execute as much software as possible. IOW it should be outputting sound loudly, while searching the disk, while playing complex graphics (ie a move), while powering a USB device, while accessing the internet, etc. Having it access many peripherals simultaneously is important. If it cannot power up, then monitor any one red (pin 4,21-23), orange (pin 1,2,12 or 13), and yellow (pin 10 or 11) wire for what each does as and after its power button is pressed.

Report all three digit numbers from those six wires. Next reply will identify or exonerate suspects.

BTW, if wires are not colored, then a PSU may not be ATX Standard. See www.smpspowersupply.com for color and pinouts.


Why would spikes on AC mains end up on a PSU output? First thing a PSU does is convert the incoming 120 VAC into well over 300 volt radio frequency spikes. If 300 volt spikes do not appear on 3.3, 5, and 12 volt outputs, then why would AC mains spikes appear there? They don't. Many only recite popular myths because many do not know how a PSU works. Do not even know of 'dirtiest' power intentionally created inside a PSU before its superior regulators and filters clean that 'dirtiest' power.

Manufacturer production and QA testing covers all of this before the supply is ever packaged and shipped. No end-user is going to do all of this, nor should they. The regulatory bodies FCC\MET Labs have inspected critical components and force compliance via regular inspections.

After reading your test methodology, I to, just want to go buy a 700W power supply and be done with it also..... and I am a component level troubleshooter by trade!

The FCC does not test the power supply for ATX, 80+ or any other PC standard compliance, they are only concerned with EMI compliance. The PSU could literally be a ticking time bomb from a safety and system integrity point of view yet still get FCC approval. Safety is UL/CSA/ETL/etc.'s jobs.

The PC-specific stuff is optional (there is no legal requirement to meet current ATX specifications to sell ATX PSU-shaped objects) so units are either manufacturer self-certified or not certified at all, which is why shockingly bad PSUs can still be legally sold nearly everywhere - as long as the PSU meets safety and EMI standards, the merchant's only liability is refunding the $20 PSU's original purchase price after it blows up $2000 worth of your components assuming the PSU fails within the merchant's return policy, after which you may have to take the fight directly to the manufacturer or "first importer" depending on local consumer protection and warranty laws.

Valid points by InvalidError. And would be obvious to anyone who actually does electronics (who is not just a system assembler).

Furthermore, a PSU manufacturer need not meet UL, FCC, or other requirements. Only the prime contractor is responsible. That responsibility lies with a computer assembler. Most computer assemblers do not even know how to test for those requirements let alone know what they are.

A power supply system is more than just a PSU. PSU manufacturer typically does not do 100% testing as was only assumed. Better manufacturers do statistical sampling. A concept well understood in facilities that actually meet quality standards. Even infant mortality still exits with 100% testing. Furthermore, testing does not report how that PSU operates with unique other parts in that power 'system'.

Anyone making PSU recommendations should have know all that - and many other functions performed by a PSU. A meter reports on far more than 3.3, 5, and 12. Obvious by anyone who knows how a PSU works and what it is required to do.

Obviously..... I was making a BIOS switch recommendation.
