Indima kagesi we-ATX ukuguqula i-AC ibe ugesi osetshenziswa kakhulu we-DC.Inemiphumela emithathu.Okukhiphayo ikakhulukazi inkumbulo kanye ne-VSB, futhi okukhiphayo kubonisa izici zokunikezwa kwamandla kwe-ATX.Isici esiyinhloko sokunikezwa kwamandla kwe-ATX ukuthi ayisebenzisi isishintshi samandla esivamile ukulawula ukunikezwa kwamandla, kodwa isebenzisa + 5 VSB ukwenza idivayisi enamaswishi ashintshana.Uma nje ileveli yesignali ye-PS ilawulwa, ingavulwa futhi ivalwe.amandla we.I-PS ivuleka uma amandla engaphansi kuka-1v, ukunikezwa kwamandla okukhulu kuno-4.5 volts kufanele kuvalwe.
Uma kuqhathaniswa nokunikezwa kwamandla, ukunikezwa kwamandla kwe-ATX akufani emugqeni, umehluko omkhulu ukuthi ukunikezwa kwamandla kwe-ATX ngokwawo akuphelele uma kuvaliwe, kodwa kugcina okwamanje okubuthakathaka.Ngasikhathi sinye, yengeza isici esisebenzisa amandla okuphatha amanje, abizwa nge-Station Pass.Ivumela isistimu yokusebenza ukuphatha ukunikezwa kwamandla okuqondile.Ngalo msebenzi, abasebenzisi bangashintsha isistimu yokushintsha ngokwabo, futhi bangabona namandla okuphatha inethiwekhi.Isibonelo, ikhompuyutha ingaxhuma kusignali yemodemu kukhompyutha ngenethiwekhi, bese isifunda sokulawula sizothumela i-ATX eyingqayizivele yamandla + 5v wokwenza kusebenze i-voltage, iqale ukuvula ikhompuyutha, futhi ngaleyo ndlela ibone isiqalo esikude.
Isekhethi eyinhloko ye-ATX power supply:
Isekhethi enkulu yokuguqula amandla kagesi e-ATX iyafana naleyo ye-AT kagesi.Iphinde yamukele umjikelezo "we-double-tube half-bridge other excitation".Isilawuli se-PWM (i-pulse width modulation) siphinde sisebenzisa i-chip yokulawula ye-TL494, kodwa ukushintshwa kwamapayipi kukhanseliwe.
Njengoba ukushintshwa kwamapayipi kukhanseliwe, inqobo nje uma intambo yamandla ixhunyiwe, kuzoba khona i-voltage engu-+300V DC kumjikelezo wokuguqula, futhi ugesi osizayo uhlinzeka nge-voltage esebenzayo ku-TL494 ukulungiselela ukunikezwa kwamandla okuqalisa.
