monitor AORUS AD27QD - can psu of monitor trip breaker?

September 8, 2020 at 09:43:03
Specs: Windows 10
Hello. I had a good monitor AORUS AD27QD. Some time ago when i was sleeping monitor was on. When i woke up all electricity went down. After switching breaker power back . Pc works fine. But monitor was not turned back. I sended to rma. Here is shop RMA message:

Shop:"We repaired PSU and sending back good monitor to client"

Is this possible that psu of monitor can trip breaker then if psu inside monitor, failed?

( somebody said :" possibly there was a power surge that caused it but no way it was the monitor. it is possible what ever did happen killed the monitor though. but it's also possible it only killed the power supply for the monitor )

So monitor psu itself caused that or power surge?

A short circuit in the monitor's PSU would trip the breaker. (Not saying that's what happened, but a short-circuit in any PSU would trip the breaker - that's what the breaker's there for.)

It seems unlikely to me that a power surge that was enough to damage the monitor's PSU (despite the breaker tripping) would not damage other equipment.

Ok fine. So its possible that psu of monitor tripped breaker then?If monitor only was stopped working after power back.

It tripped the main breaker? Most houses and apartments have breakers for various parts of the structure that run through the main. For a problem inside the house one of the other breakers should have popped leaving the others working. If it was the main I'd suspect the problem was elsewhere, probably external to your house. Did any of your neighbors have a similar problem?

I agree with ijack and DAVE: The PSU probably
failed in a way that caused a short circuit inside it, tripping
the circuit breaker. Very straightforward. As ijack said,
that is what the breaker is for.

What else is connected/loaded to the "breaker" in question?
If at the time the monitor psu (build-in or external brick?) shorted (and blew its internal fuse) some other appliances where active (refrigerator?), it could have raised the piek-current over the breakers rating....

just a possibility...

Hey i forgot. Wanna say.
I had a good monitor AORUS AD27QD. 2 months ago when i was sleeping monitor was on. When i woke up all electricity went down. After switching 2 small breakers power back . Pc works fine. But monitor was not turned back. I sended to rma. Here is shop RMA message:
Shop:"We repaired PSU and sending back good monitor to client"
Is this possible that psu of monitor get failed and trip breakers?

That situation was 2 months ago ,too.

I think i have good wired electricity in house,rooms.I am living in apartment building ( block 4 floors )

So just i had bad luck , that first it was monitor and then halogen bulb?

Somebody said this to me:"As others have stated, the most likely issue is a problem with the electrical wiring in the house and it's frying your electronics."

So he is right that electrical wiring frying my electronics?!

Or something external caused psu to die in monitor or not?

Unless there was an humungous power surge I doubt anything external would cause a psu to fail. A lightning strike "might" but psu usually fail 'cos they fail...

Surge limiters (which allegedly can help protect against lightning strikes at times) are pretty common in USA - and to a degree in Canada;. Popular due to the way power is transmitted/ delivered to many homes etc. (over head wiring). In the UK and many parts of Europe it's nearly all underground; and in many parts of Canada it's that way too. Etobicoke (west of Metro Toronto) was the first to go that fully way...There are "no" overhead wires allowed of any kind; nor antennas on towers/roof tops allowed. Mississauga (even more west of Metro Toronto) has both the olde and new styles; some overhead and some underground. Out in the sticks of course it's all on poles and overhead wires...

Faulty wiring wouldn't fry a psu; it might cause the breaker/fuse serving the mains outlet to trip out/blow - but that's all.

a ok so it was propably like ijack said:"A short circuit in the monitor's PSU" ?

Shop sended me email:"Shop:"We repaired PSU and sending back good monitor to client""

Yup something along those lines... Electronics ain't perfect and invincible; and most are designed to fail at some stage (certainly in the domestic arenas...)

Hey again. Last question and thats all. Is this possible that power surge ( somebody told me that ) killed my previous AORUS AD27QD monitor or its doubtful?:)

Anything is possible in that regard. If the monitor was a “cheaper/not well known” brand... who knows what quality of components went into it.

The two areas where cost cutting is sought are the psu and actual display matrix (the actual led screen) itself.

The rest of the components can be resourced to lower specs, qualify than in say well known brands; but even the big boys will try to cut cost, cut corners etc. when they can get away with it

And then again there is alway the odd one in a batch that just fails regardless?

Surge protectors are certainly more widely used in Canada/USA than in the UK; and perhaps wise to consider one?

Hey last question. Somebody said this to me:"

"halogen bulb doesn't trip your circuit breaker, it got burned cos of the sudden power disrupt."


I dont understand. So not possible , that bulb will get burn itself, but power disrupt? Whoot?

Halogen bulbs, just like the original filament bulbs can go any time; and a voltage surge "could" pop one... Though I've not known of it personally.

As they age halogen filament assemblies slowly sag, and the result is that the filament itself shorts out...; and can trip the breaker in the process.

Not uncommon when a bulb blows (dies) be it halogen, filament or led styles. to trip a breaker when the bulb "blows' dies... I've had it happen with current led replacements for original filament bulbs.

And tv studios when we used high wattage lamps (500watts, 1kw, 2kw etc.), if they "blew" (one usually heard it too) they could (often would) trip the breaker for the dimmer it was on; which was easily reset of course...

Ok with new bulb no issues.So i guess i had a bad luck with that halogen bulb ( 2 weeks ago ) and psu in monitor AORUS AD27QD ( 2-3months ago ) ?

There are likely el cheepo halogen bulbs around with questionable life times... And then there good bulbs and occasionally one can burn out sooner than it ought.

Also halogen bulbs usually come a note stating how they’re to be used; vertically, or horizontally, or whatever; sometimes advisories re’ angles of use...

The monitor appears to be a decent make/model... But that doesn’t rule out having a low spec psu within it.

Also one needs to ensure any air vents on a monitor are dust free, to prevent possible overheating...?

I was stupid. I remember that many times i left running games for 12 hours with monitor on. And maybe he get just overheated and psu inside monitor.

Very good possibility... if not using a monitor for a while, either power down fully, or put it into standby mode. The former is better than the latter. The latter still uses electricity...

Very typical domestic spec’d displays are designed for extended power on and in use sessions; unless there is decent cool(er) air flow around them

Hey last question. Really greatful for help.

Somebody said this to me:"Sounds like there was likely a power surge from the outside especially since 2 breakers were tripped. If it was anything internally it should have only affected one breaker."

So it was surge?


It was tripped 2 circuit breakers like i said before.

Possibly, probably... But who really knows without serious investigation of the distribution panel, house wiring and everything connected?

Possibly....no way to know for certain. If blackouts, brownouts or frequent storms are in your area, it'd be worth it to investigate a solution for surge-protection or put the machine(s) on a reputable UPS.

"So?"

Same as before. Investigate installing surge-protection/UPS devices. Unless you're willing to move to somewhere you know has "cleaner" incoming power...

Somebody said this to me:"I am a registered electrician in the state of Wi and I'm going to tell you to call a local electrician because something isn't right with your household's wiring. You need somebody there in person to find the fault meaning this is outside the scope of what we can help with on a forum. "


So he is right?
