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

Im using a DIY surge protection with fuse. Voltage here in Cebu City is not so critical but voltage surge/fluctuations, hehehehe naa gyud and its fatal to appliances. No need for AVR since your CPU power supply has a feature for voltage regulation.

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),..

On the economic side, keeping this facts in mind, manufacturers of power supplies may want to reduce cost to yield higher profits. So they could use lesser components for power regulations..since they are dealing with a power consumer that is processing digital signals.

Thanks.

b4 i use AVR but now not anymore... i don't connect my LCD to CPU power supply.. just plug it to my outlet nga naay switch...

ok ra walay AVR basta ok ang kuryente sa inyong lugar. kung diritso gani plug sa outlet (wall), ayaw sige ug ibot-taod sa power cord, kay mo spark inig taod, guba gyod na power supply sa computer (maybe apil pa ubang parts).

cge na mn ko experience ani cge paslak dn spark sobra na tuig na pero so far wala pa mn nadaut ako notebook ug PC...

maybe if cheapo imo power supply seguro gub on jud na kay unsa ra mn tawon sulod anang generic kaysa branded(thermaltake my PSU).

Kadtong naay concern sa paggamit ug AVR para sa injong puter. Basaha lang ninjo ang specs sa injong puter-PSU kung sa tanaw ninjo loaded na or ang tanang ckt. sa AVR on-board nasa injong PSU.Sa akong opinion puede ng deli mag butang ug AVR.

Naka experience nako og spike sa amoa once.. nibuto jod ang fuse sa AVR madungog god.
May nalang kay wala nako giON ang PC diretso sa outlet.
Siga ta to pod..

Mas mahal baya ang PSU kaysa AVR.
Just a thought.

mas mosuggest pako UPS nga naay surge protector kay naa pa ka time to power off ur sytem kaysa AVR nga 50/50 ang either mamatay(can't save ur file) or maintain ang flactuation(safe but not safety at all)

Brad naka open kanaba ug PSU power supply? And kanang 220V socket sa PSU where diha i plug ang monitor, ug subayun na nimo ang connection ana parallel rana sa AC power line nga 220V ug wala mag gamit ug AVR, ug my AVR man sad na gamit, the monitor is not using the regulated DC output voltage of the PSU. In a setup with AVR the monitor is using the regulated AC power output of the AVR and not from the DC power output of the PSU.

Sir I respect your high degree of technicality, your right, naka parallel ra na siya sa AC, basing on the on your response dili questionable nga kamao gyud ka mangabli ug mangayo ug mga consumer electronic appliances and your not a newbie around computer repairs either.

Pero gibasa nimo ug gitubag nimo ang ako post nga putol-putol, if imo basahon ug tarong ang ako post ug ang uban sad, I was refering to the Mobo, and the Monitor being the subject matter here, 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..

unya kani

kinsa man imo giingnan ani?

I have a UPS, and still it had blown my board. There was a brownout, power went up and down like crazy, many times a second, aircon made a strange noise, but survived. After that, the computer wont start, figured out, the board was blown. So what? A 4t pesos UPS could not save my board, nor could the PSU.

pagkapait diay sa imo na encounter. so, i believe mas maayo kung dili sa ta maggamit og computer during times na brownout or high ang flactuation sa current. Wait lang ta kadiyot na mustable ang current. ang AVR, UPS and Surgeg protector will prevent first strikes of current instability. pero it doesn't dili na siya madutlan.

OT: mura ra ni og bullet proof. it doesn't mean nagsuot ka ana di na jud ka madutlan. so kung natapsingan ka na tago na lang.
