POWER SUPPLY

[THINKER100X]

Sir sino po ba marunong mag-ayos ng power supply? Yun pong mga power supply ko d2 lahat walang power..i mean pagkinokonek ko sa mobo walang power..chineck ko n po ung loob ng PS pero ok pa po nmn lahat...trinay ko na ung fuse ilipat sa ibang power supply ok p nmn...ung mga capacitors d p nmn nadadamage...ok pa po....Ask lang po ako kung anong piyesa ung dpt kong palitan d2 para muling magkaron ng power..d2 kc s masbate hindi stable kuryente kaya halos lahat ng may mga PC karamihan power supply ang sira so inisip n kawawa nmn po ung mga kababayan ko..pupunta p po ng legazpi o kaya cebu or maynila makabili lang ng power supply....so baka po may alam kayong paraan kung pano ayusing ang power supply para makatulong nmn po ako s mga kababayan ko rito....

i would wanna try to help,... but its pretty hard for me 2 understand tagalog,..... (just cebuano)

Sir thanks for the help....i ddnt know also how to speak cebuano so i prefer to have it like this....what i mean is i have a power here..it was 3 of them that has no power....i try to transfer it to other mobo just to test it but then it was nt giving suppy to mo motherboard...i take out the fuse and transfer it my good powersupply just to test it also if the fuse is good and then it also good...what am i asking Sir is if there is a solution of this power supplies...i mean i dont know what thing i should replace in the power supply... i just wanna ask also if there is a solution about my problem before i buy new power supply....

it could be a diode problem.... it receives power from outlets but it can't power on the system, it would just give a click power.

Hmmm, your current there is unstable and always fluctuating?

The #1 Cause for problems in PSUs and MOBOs....

I suggest you get a "good" AVR... At least it can minimize the fluctuation of your current...

dark_humbz,..... yeah ur right,... i'v notice dat the electricity current in the philippines (Cebu city to be precise) is not stable especialy around noon,.....

well datz how my parents Ice maker broke,...

@ THINKER100X : just wondering how long have u had ur PSU,.... and is it a good brand? or a generic brand?

check first if your powersupply is working by shorting the green wire to the ground(any of the black wire). if its working, check the voltages in the 20 pin connector. red has should have 5v, yellow should have voltage at least 11.7v to have a stable output, orange wire should have 3.3v, white wire should have -12v or less. if your ps is not working when the green wire and the black wire is shorted, start checking in the rectifier(the bridge diode with ~, +, - marking or it is composed of 4 diodes connected in brigde) found after the transformer. if it is ok, check the filters(the big capacitors). if still ok, check the transistors(voltage divider and the voltage regulators) attached to the heat sink. if the transistors are ok, check the resistors and the diodes surrounding the transistors. those are the most common defects in powersupplies. if the out put voltages are not equal or below the expected voltage, then change the transistors. the transistors maybe ok when tested but their values may have changed

note: you should have knowledge in basic electronics and component testing. good appearance of the component does not mean it is functional.

get a good AVR na lng para hindi madadali power supply mo...

Sir thanks for all your suggestions... thanks,thanks, thanks....
