Hi po;

Ano kaya sira ng PSU na ito, Click lang tapos nde tumutuloy. solution na ginawa ko:

- pinalitan 3 na leaky capacitor
- Resoldered

Pinaghihinalaan ko baka yung PULSE WIDTH MODULATION IC dbl494 siya.

isa pa tanong nakalimutan ko kung ano yung ipagdidikit para mag-run yung psu kahit wala CPU. anong number ng pins po ba yun?

thanks

IIRC pin 14 at katabi netong ground wire. Green saka black para mapull down ground yung pin14. May marka rin minsan na PS on tapos jump mo sa ground nya.

Di ko maget yung meaning ng CHS mo.

Pero satin naman standard yang ganyang header. sa 20 pin, pin 14 yan bale green wire, tapos tigkabilang katabi nyan ay black wire which is com or ground niya. Pwede mo na ishort sila para mapower yung PSU ng siya lang. Kapag 24pin naman bale nadagdagan ng dalawang wire sa kada linya niya kaya papatak siya sa pin 16.

Ganito bilang nyan sa ganang akin 1 2 3 4 5 6 7 8 9 10
11 12 13 14 15 16 17 18 19 20

Karaniwan naman nyan green wire at isang black wire ang ishort.

to trouble shoot that psu, you need to find out if the 5 volt standby circuit is alive...me masusukat kang ~3.5 volts sa pin 14, then kung meron yan, ishort mo yung pin 14 sa katabing black na wire, dapat mapower up sya, iikot na yung fans.....
