yung voltage sa pin 14 dapat nasa 3.5volts or higher...

possible din kasing ang design nila eh iba pa rin yung internal supply sa standby output...


@TS,

kapag inishort nyo ba PSON# to ground eh sticky o momentarily lang?

How about yung output after nyo ishort, may naobserved ba kayong voltage kahit residue lang?

IME, all atx psu's i have seen have this standby 5volt rail.....loss of this rail means loss of signal at pin 14....

@ master glutnix_neo..meron pero less than 1vdc lang sa may 12vdc, may napansin aku sa pin #12 may .13vdc kahit na nka stndby lang. Dba sa pin 9 and 14 lng may voltage pag nka stndby ung unit. Na compare ko to sa working ng PSU. Any idea bakit may reading sa pin #12. TIA

Magkaiba ba ang ckt ng standby sa main sir? o pareho lang sila ng start-up resistor?
I'm talking about the resistor in the range of 1Meg.

Steady po master, tapos check sa fan kong ekot o hindi, pag hindi sabay tagal ng short-pin sa pin 14.

meron?!!! oh no, napakakumplikado nito, pero nawawala ulet yung 5V signal na yun?

Ang iniisip ko kasi baka nagOn on ang supply mo then after sometime may natitrigger na protection kaya namamatay, so pagkasukat mo patay na sya.

ganito pag plug ko ng corg tapos reading sa may 5vsb ok, sa power ok, may 5vdc, pag e short ko ung green at blk wla d parin mag switch, ganun parin may voltage parin, kasu ayaw tutuloy sa 12,5,3.3,-12 d rest wla.

yes, ganyan nga, it happens so fast you think it did not happen...

i suspect shorted rectifiers sa mga rails.....ganyan kadalasan ang naeencounter kong sira ng psu...

better i maka post ng pics si ars......

 yan din ang kalimitang kung na e encounter na sira kalimitan shorted yung rectifier nya na 3 pin.. check mo yun.
