560W Silverstone PSU

[Mathersalan]

This has come to an aggravating issue. My 560W Silverstone Zeus PSU contantly trips the Arc fault breakers for the bedroom in my new house. This only happens when I power on. Press the power.. pop it takes about 6 times for the machine to actually power on without it tripping the breaker. It will also randomly once in a while just trip the breaker with the computer running. I am not so sure if its faulty wireing or my PSU is defected and needs to be RMA'd! What do you experts think about this?

This never happen with my older PC which had a generic brand 350W PSU

The breakers are regular 20amp AFCI breakers

Now that I am starting to OC my CPU, each time it restarts after setting the cpu clocks.. pop breaker blows and fails to OC due to a bad restart :(

Try moving it to a different outlet and see if it still trips. It's either the PSU is failing ( fast! ) or you have a site wiring fault. Although I assume its a new house and the electrician was decent, it never hurts to check before beginning the RMA process.

I just tried 3 different rooms that were on an AFCI breaker. The breaker tripped when power on in each room. I tested several rooms that did not have an AFCI breaker and it actually powered on 5 times without tripping the breaker. Since it trips all the rooms with arc fault breakers I am thinking the PCU could be defected, or something up with the wiring in my house

I'd lean towards RMA'ing the PSU first. Repairing wiring is a pain and expensive, not to mention the fact that it seems your AFCI breakers are saving your bacon. I'd RMA it.

Yeah I what I am about to do, let alone I'll have a one week break off of the PC while the PSU is being RMAd


And by saving my bacon do you mean those AFCI breakers were actually protecting my system from the PSU frying my setup?

Turns out it was the PSU.. Bought a modular corsair 520W but RMAd the silverstone works well now. I'll be using the silverstone in my other test computer and for backup. Hard to believe such a good PSU can be defected!

PSUs are not infallible. :)

I'd also take a look at the wiring you have in place. Tripping a breaker as often as you said suggests that there is more to this than a mere PSU.

It stopped tripping when I replaced the PSU, and it would only trip when power on. It's been a week almost two so everything should be fine on both wiring and PSU part
