Muaj ntau cov lus qhia txog kev sib txuas hluav taws xob cables
Rau cov khoom siv hluav taws xob sib txawv, cov khoom siv hluav taws xob sib txawv, tab sis lawv txhua tus cia siab rau cuaj xim ntawm paj ntsuab: daj, liab, txiv kab ntxwv, ntshav, xiav, dawb, grey, ntsuab, thiab dub. Tag nrho cov khoom siv hluav taws xob pC tuaj nrog cov 9 xim ntawm cov xov hlau (tam sim no cov khoom siv hluav taws xob tseem ceeb tshem tawm cov xov hlau dawb).
Yellow: +12V
Cov kab daj yuav tsum yog ib qho ntawm ntau hom khoom siv hluav taws xob. Nrog rau qhov sib ntxiv ntawm optical thiab floppy drives, spindle lub cev muaj zog thiab nrhiav lub cev muaj zog, nrog rau kev ua haujlwm voltage thiab serial device logic teeb liab theem rau ISA slot + Thaum qhov hluav taws xob tawm ntawm 12V yog qhov txawv txav, feem ntau ua rau kev nyeem ntawv tsis ruaj khov ntawm hard drives, optical drives, thiab floppy drives. Thaum qhov hluav taws xob tsawg, nws tau tshwm sim raws li qhov loj disc xaiv nyob rau hauv lub kho qhov muag tsav, ib qho kev nce nyob rau hauv lub logic tsis zoo lem nyob rau hauv lub hard drive, thiab nquag tshwm sim ntawm phem lem, ua rau lub kaw lus yuav poob thiab tsis ua hauj lwm zoo. Thaum qhov ceev ntawm lub optical tsav yog siab dhau lawm, nws yog ib qho yooj yim los poob tswj thiab tawg, ua rau stalling thiab spinning ntawm lub hard drive. Tam sim no, yog tias muaj qhov tsis txaus ntawm +12V fais fab mov, nws yuav cuam tshuam ncaj qha rau kev ua haujlwm ntawm daim npav pCI-E thiab cuam tshuam rau CpU, ua rau muaj kev sib tsoo.
Xiav: -12V
-Ib qhov hluav taws xob ntawm 12V yog siv los muab qhov kev txiav txim siab theem rau qhov chaw nres nkoj serial, uas yuav tsum muaj qhov tam sim no me me, feem ntau qis dua 1A. Txawm hais tias qhov sib txawv ntawm qhov hluav taws xob loj dhau lawm, nws yuav tsis ua txhaum, vim tias qib 0 qib ntawm cov logic theem ntawm -3V rau -15V, nrog ntau yam.
Liab: +5V
Tus naj npawb ntawm +5V xaim yog sib npaug ntawm cov xaim daj. +5V fais fab mov yog qhov ua haujlwm voltage muab rau kev sib xyaw ua ke xws li CpU thiab pCI, AGp, ISA, thiab lwm yam. Nws yog lub zog ua haujlwm tseem ceeb hauv cov khoos phis tawj. Tam sim no, CpU siv cov khoom siv hluav taws xob sib txuas ntawm +12V thiab +5V, thiab cov kev xav tau rau nws tsis siab dua li yav dhau los. Qhov tseeb version ntawm IntelATX12V2.2 tsuas yog txhim kho lub +5V fais fab mov muaj peev xwm thiab txhim kho lub zog ntawm dual core CpU. Qhov zoo ntawm nws cov khoom siv hluav taws xob ncaj qha cuam tshuam rau kev ruaj ntseg ntawm lub computer system.
Dawb: -5V
Tam sim no, muaj tsawg heev cov khoom siv hluav taws xob ua lag luam nrog cov xaim dawb, thiab dawb -5V kuj yog siv los txiav txim siab theem ntawm cov logic circuits. Nws yuav tsum muaj qhov me me tam sim no thiab feem ntau tsis cuam tshuam rau kev ua haujlwm ntawm lub cev. Nws yog qhov yooj yim xaiv.
Txiv kab ntxwv: +3.3V
Qhov no yog tsim tshwj xeeb rau ATX fais fab mov los muab lub zog. Nyob rau hauv qhov tseeb 24 tus pin lub ntsiab interface fais fab mov, qhov tseem ceeb tau muab tso rau kev ntxiv dag zog rau +3.3V fais fab mov. Qhov yuav tsum tau muaj voltage yog nruj, cov zis yog ruaj khov, lub ripple coefficient yuav tsum me me, cov zis tam sim no yuav tsum loj, thiab nws yuav tsum yog tshaj 20 amperes. Qee qhov nruab nrab mus rau siab kawg motherboards siv high-power field transistors los tswj lub hwj chim mov ntawm lub cim xeeb rau kev nyab xeeb, tab sis lawv kuj yuav hlawv tawm lub transistor vim lub nco plug. Lub platform siv +2.5VDDR lub cim xeeb thiab +1.8VDDR2 lub cim xeeb, thiab cov hluav taws xob hloov hluav taws xob tau nruab rau ntawm lub motherboard.
Ntshav:+5VSB (+5V standby fais fab mov)
ATX fais fab mov muab +5V720MA lub zog rau lub motherboard los ntawm pIN9, uas muab lub zog rau WOL (Wake up OnLan), pib Circuit Court, USB interface, thiab lwm yam circuits. Yog tias koj tsis siv cov haujlwm xws li kev tsim lub network, thov tua cov haujlwm no thiab tshem tawm lub jumper los tiv thaiv cov khoom siv tam sim no los ntawm +5VSB fais fab mov kawg. Lub zog hluav taws xob zoo ntawm qhov tso tawm no ncaj qha cuam tshuam rau lub zog noj ntawm lub khoos phis tawj thaum sawv ntsug, uas ncaj qha txuas rau peb cov nqi hluav taws xob.
Ntsuab: p-ON (lub hwj chim hloov kawg)
Tswj lub hwj chim los ntawm qib. Thaum lub teeb liab theem ntawm qhov chaw nres nkoj ntau dua 1.8V, lub ntsiab fais fab mov yog muab tua; Yog hais tias lub teeb liab theem qis dua 1.8V, lub ntsiab fais fab mov yog qhib. Siv lub multimeter los ntsuas cov zis theem teeb liab ntawm tus pin no, feem ntau nyob ib ncig ntawm 4V. Vim tias qhov hluav taws xob tso tawm los ntawm tus pin no yog lub teeb liab theem. Ntawm no yog ib txoj hauv kev ua ntej los txiav txim siab qhov zoo ntawm cov khoom siv hluav taws xob: siv cov hlau hlau kom luv luv ntawm qhov chaw nres nkoj ntsuab thiab txhua qhov chaw nres nkoj dub. Yog hais tias lub hwj chim mov tsis teb, nws qhia tau hais tias lub hwj chim mov puas. Ntau cov khoom siv hluav taws xob niaj hnub no tau ntxiv cov kev tiv thaiv hluav taws xob. Tom qab luv luv circuiting lub hwj chim mov, yog tias tsis muaj load ntxiv, nws yuav cia li kaw. Yog li ntawd, txhua tus neeg yuav tsum ua tib zoo saib xyuas qhov pib ntawm lub zog tam sim ntawd
