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 emgqeni, umehluko omkhulu ukuthi ukunikezwa kwamandla kwe-ATX ngokwawo akuphelele lapho kucishiwe, kodwa kugcina amandla amanje abuthakathaka. 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 ne-voltage engu-+300V DC kumjikelezo wokuguqula, futhi ugesi osizayo uhlinzeka nge-voltage esebenzayo ku-TL494 ukulungiselela ukunikezwa kwamandla okuqalisa.
