Gudam po sir tony ask ko lag po pag ang PSU ay mag on sya ng 1 or 2 sec tapos patay na sya, primary ba ang problem nun or sa secondary? ano po kadalasan pinapalitan dun sir?
tony on August 08, 2008 10:58 AM
enermax ba yan? short mo yung c-e junction ng fan switch....
dhoods on August 08, 2008 01:41 PM
hindi sir geniric power supply lang, san po ba matatagpuan yun C-E Junction switch? Sir pahabol, kc sir binabasa ko itong thread about the varistor, tama poba ang kagka intindi ko na yun varistor ay naka series sa isang polo...ano poba mas mainam, mauna muna ang fuse bago varistor or varistor muna bago fuse sa pagka series nila sir
tony on August 08, 2008 01:47 PM
kung generic, check mo yung secondary rectifiers or maybe a shorted diode...on the secontadry rectifier side...
dhoods on August 08, 2008 01:54 PM
sir how about dun sa varistor naka series poba or naka parallel sa line ang kabit niya, ok na pong yun psu, tama po kayo may shorted na diode sa secondary rectifier nya...thanx alot po master idol hehehhe
Base on page 3 po yan, nafix ni dhoods ang PSU nia. Galing nmn! Anu ba ing C-E junction swicth?

sigh* , sir di mo naman sinagot yung pinagagawa ko eh :(, sabi ko sayo sukatin mo muna yung violet para mas mapinpoint kung san banda yung sira( its always a case to case situation depende sa brand ng unit specifically sa design).
1. varistor is part of protection circuit specifically from failure on input voltage so obviously nakalagay yan bago pumasok ng bridge type rectifier.
2. minsan dalawang klase ng transistor yung nakalagay sa secondary heatsink 1 is C E T junction switch na may triggered voltage then other 1 is mosfet pnp junction switch which is compose of combination of diodes/rectifier. yan nga yung pinapachek ko sayo.

mga boss, tanong lang..... meron akong 750W DELL XPS 710 psu na pag unang on, ok siya.... pag pinatay mo di na aandar uli until after mga 1 hour...
kahit ishort ko pa yung +5V stand by good (green) wire to ground sa 24 pin connector, ayaw umandar... madali lang kaya ayusin nito?
sino kaya dito kaya mag ayos ng power supply? sayang kung di ko magagamit sa DELL XPS ko... kahit as backup ng psu na nakalagay dun ngayon...
thanks!
