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.

Sure. I'm not going to say no to that because you are applying voltage to it.

The analogy though is something like..... "Should I wear a helmet in my car even though it has airbags?"

Your motherboard should not be taking on tasks that your power supply is supposed to accomplish. You could also just go buy a surge suppressor/UPS to plug your power supply into. That unit would be more capable than Asus' anti-surge circuit.

I've read tons of threads about Asus' anti-surge circuit triggering prematurely. I don't think I've ever seen an article or thread about how Asus' anti-surge circuit saved someones PC. This is a task for your power supply's built-in protection circuits. The motherboard only gets DC voltages and if your 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.
