Did somebody blown a PC by not using an AVR or UPS?

[softtouch]

---

The situation is that:
You sit on your computer as the UPS starts beeping, the aircon make strange noise, but the lights are still on.
Seconds later, the power is completely off.
After power is restored, the comp wont start, thats it. No way to prevent that.
The UPS was not able to handle this many times a second power up and down and on/off.
A "normal" brownout, where the power falls quickly to 0V is no problem, but this one was strange.

bitaw sad, paspas man diay ni imo situation. wa jud ta lain mabuhat ani. ilisan na lang ang mga affected na appliance or PC parts.

di pa jud ni covered sa warranty noh?

[softtouch]

No warranty... however, bought a new board and looking now for a reliable UPS, but what they sell in SM is in my opinion just "crap"...

[jintatsu]

ah... ok.. la gyd ko nka suway sa imong nasuwayan softtouch..

I am not using commercial grade surge protectors. I only made myself using gauge 16 wire wound on a ferrite bar and some side items. So far so good. Even AVR's nowadays doesn't guarantee any protection bisan sa iya AC cord pwerteng gamaya.

In my experience daghan na nga case ko nasulayan nga guba gyud ang monitor tungod sa power surge,and it derives its 220v from the CPU power supply

Here's a more complete part of you post:

I think we should not trust too much on the CPU power supply, because in my personal experience and also on the electronic side and also on the economic side, dili kaayo gyud kaayo nato kasaligan ang Power supply sa CPU nga maoy mo regulate sa voltage,

In my experience daghan na nga case ko nasulayan nga guba gyud ang monitor tungod sa power surge,and it derives its 220v from the CPU power supply, on the electronic side this one we need to consider, Digital signals are not really prone to noise mao nga dili kaayo sila kinahanglan ug maayo nga regulation that's why some cheapo or even high-end power supply manufacturers are not really concerned with a very smooth power supply hence transfer of data from the CPU to the GPU for example is not a problem even if the signals are not really smooth because the computer is smart enough to decode what type of data is being inputted because signals are digital ( 1's and 0's),..

Makita nimo ni correcttion lng ko because ana na part, and that has nothing to do with the mobo story you mention on your other post, letra for letra klaro ug tataw gyud na imong gi sulti on your own experience may mga na guba na monitor, diba? and its because of the power surge and" it derives its 220V" which means coming from obtain from or receive from the CPU power supply. Reading all your other post will not change the meaning of this that made me explain in a way na spoonfeeding na gyud.

wala na nako gi detalye nga kailangan iconnect dinhi kay makaguba, that post was for newbie, no need to detail out asa siya naka connect..

I am not trying to tell you where is it connected, am telling you where the monitor got its power source.

This is what am trying to correct, that the CPU power supplys operation has nothing to do with the monitors 220V power source it only provide an AC socket extention from the power AC source from the AVR. Medjo akong lng na spoonfeed ug maayo brad pasenha na because i just found a need to do it that way.



Another thing akong e add ug comment, this is about the digital signal you also mentioned.
"Digital signals are not really prone to noise mao nga dili kaayo sila kinahanglan ug maayo nga regulation"

I have a correction on this one "digital signal" needs proper voltage regulator, the word digital may just look to us 1's and 0's, Yes it produce less noise than analog circuits but it also needs a less noise power source. Take note of the word signal. A signal could mean radio signal, sound signal, computer signal in our own easy term, which deals with speed or power commonly named as Mega Watts in power ang Mega Hertz in speed, this two example needs a good regulated steady state AC and DC supply to support its expencieve circuitry. An example in theory is a 100% radio frequency modulated signal in which at a 1 kilometer distance from the transmitter only 10% will reach at that point, that,s in a line of sight computation in which wala pa gi subtract ang signal lost cause by obsraction sa ana na 10%, In ana ka important ang regulated power supply sa digital signals, Sa ma recall naku before sa ga skwela pako wa gyud ko ka gamit ug signal generator nga dili regulated power suppy ang nag power. So for me lang ha i dunno sa uban ha , its wrong gyud to say nga "dili kaayo sila kinahanglan ug maayo nga regulation" ang digital signals.

Peace and no strings attached just purely sharing

wow all ai can say that is impossible boss kay ang psu sa pc... usa man na sa pinaka stable na design for pc.... then na man sad na fuse mo blown lang cguro na ang pc nimo kong ang imo power suppy wala na fuse.... any electronic device or electrical device basta naa fuse dili jud na mo boto kong dili sad mo agi sa fuse.. so kong naaa man gani maguba or over current or voltage ang fuse jud ang unsa ma damage.............. am lang kong sakto basad ko... mao man na ako na observe.... sa alo loa.. an dancer......

[nodols3]

Nakalitan ko adto da.. bravo ..Mr. Teban...I salute you..ECE ka? just curios here...

Sorry pero wala gyud ko kasabot ani kay mura communication mani nga subject..

sayop ako gamit nga word ani da:

and its because of the power surge and" it derives its 220V

dapit diay unta ako gitarong abi man gud nako walay expert mobasa...

Ok ako i-correct...Ang Monitor nga kanang naka connect sa luyo ang iyang AC which is 220V,..kaila naman tingale mo unsa na power supply no..kanang murag box nga metal na sagad tawag nila 300Watts naa na gani 600Watts karon..Mao na ang PSU..
Ug imo iconnect ang 220v AC nga wire sa monitor sa Power supply sa CPU mura ra na ug naka connect sa inyong matag-usag usa nga mga outlet sa balay.. sayop na ang word nga "derive" dapat diay gi "connect" sa PSU, unya ang kana nga wire nga para sa 220v nga sagad iconnect sa Voltage regulator ug subayon nimo ngadto gyud sa ilawon sa power supply wala nay lain connection kundi didto ra gihapon padung sa outlet na..wala na relation what so ever sa power supply sa CPU nga regulated.. ok na solve na..sabot mo ato mga newbie? libog gamay da kay taas.

Lain na sad..

I am not trying to tell you where is it connected, am telling you where the monitor got its power source.

sakto sad ni..daghana nako sayop gyud da.. So it's power source is from the outlet sa balay kana kung wala kay voltage regulator, or UPS ba kaha..in english it derives it power from the outlet nga gikan sa VECO(distributor ni sila ug power dili sila ang naga supply ang MERALCO ug wa ko masayop.) kung naa ka sa Cebu..

..
O sakto kaayo ni,,,but to some extent set by the standards, kana ug unsa nga degree of regulation ug unsa sad ang imong reference para makaingon ka nga proper regulation..also take note that wala ko moingon ug dili proper ingon lang ko dili kaayo...
and that doesn't necessarily say nga "dili proper" but one true fact remains that it needs proper regulation depende lagi ug unsa nga standard ang imo gisunod..nakabasa raman gud ko ato sa libro, mao ako nalang sad gisugyot ninyo..nga dili lagi kaayo kinahanglanon ug maayo nga regulation, sorry po..sayop gyud to libroha da...sunogon ko to oi...

kani naglibog ko:

Yes it produce less noise than analog circuits but it also needs a less noise power source.

Kinsa man ang nagproduce ug less noise?

Ngano man ni? Nisamot na gyud ko kalibog..naa naman gud transmitter ani..I know trasmitter needs good power regulation..out of topic naman ni tingale ni pero mura di ko sure..sige lang I’ll assume nga correct ni kay sa libro man tingale ni gikopya.. pero ngano naa naman transmitter diri..ahh sige ra oi..

In ana ka important ang regulated power supply sa digital signals

paminaw nako layo naman ni kaayo sa computer ug sa signal transmission nga imo gidiscuss nga imo pa gikuha sa libro… be,,taronga kuno ug relate na be…ang signal transmission ug kanang imo giingon nga

In ana ka important ang regulated power supply sa digital signals

..I’ll wait for your answer nalang..

One for the brain bleeder lang bro basin nakalimot naka sa decoder nga akong giingon..puerte raba daghana klase sa decoding technique.. Also signal transmission and reception depende naman tingale na sa coding and decoding technique imo gigamit, if ever related siya sa regulated power supply sa PC mura it would be the least and very much away of the subject matter and a concern here...



clarification lang po..no bias no hard feelings simply sharing…peace to you and to all..

wow all ai can say that is impossible boss kay ang psu sa pc... usa man na sa pinaka stable na design for pc.... then na man sad na fuse mo blown lang cguro na ang pc nimo kong ang imo power suppy wala na fuse.... any electronic device or electrical device basta naa fuse dili jud na mo boto kong dili sad mo agi sa fuse.. so kong naaa man gani maguba or over current or voltage ang fuse jud ang unsa ma damage.............. am lang kong sakto basad ko... mao man na ako na observe.... sa alo loa.. an dancer......

sorry bro pero daghan nako naayo nga electronic devices nga wala ka boto ang fuse..pero nay mga pesa naguba..depende sad sa type sa fuse nga gigamit usahay, usahay paspas(sakto ba kaha nga termino) kaayo ang power surge nga dili gani kaboto ang fuse.. os dili na impossible.

peace.. :mrgreen:
