Saib Cov Kev Sib Txawv hauv Zog Cov Kev Cai
Taw qhia
Tau ntau xyoo, lub hauv paus ntawm cov tshuab computer tau hloov ntau heev. Txhawm rau tsim kho tus qauv, cov qauv qhia ntawv tau tsim rau cov computers hauv kev lag luam uas txheeb xyuas ntau qhov me me, cov ntawv sau thiab cov khoom hluav taws xob kom thiaj li hloov tau yooj yim ntawm cov muag khoom thiab cov tshuab. Vim tias txhua lub tshuab computer yuav tsum tau hluav taws xob fais fab uas hloov dua siab ntawm cov phab ntsa hluav taws xob mus rau cov khoom siv tsawg uas siv los ntawm cov cheebtsam, cov khoom siv hluav taws xob muaj meej meej heev.
AT, ATX, ATX12V?
Txuj kev tsim qauv duab tau muab ntau lub npe ntawm cov xyoo. Tus thawj Advanced Technology los yog AT tsim tau tsim nyob rau hauv cov PC thaum ntxov nrog rau IBM lub nruab. Raws li qhov yuav tsum tau muaj zog thiab teeb tsa kev hloov, qhov kev lag luam tsim ib lub ntsiab lus hu ua Advanced Technology Extended lossis ATX. Qhov kev qhia no tau siv ntau xyoo. Nyob rau hauv qhov tseeb nws tau undergone ib tug ntau ntawm cov kev hloov kho los ntawm lub xyoo rau nrog ntau lub hwj chim hloov. Tam sim no ib hom ntawv tshiab tau raug tsim los ntawm lub xyoo hu ua ATX12V. Tus qauv no yog lub npe hu ua ATX v2.0 thiab saum toj no.
Qhov kev sib txawv nrog qhov tseeb ATX v2.3 thiab ATX v1.3 yog:
- Kev siv ntawm 24-Pim Qhov Chaw Zog Hluav Taws Xob Hla 20-Pin Connector rau PCI Qhia Kev Txhawb
- 6-Pin Aux Zog Hluav Taws Xob Tsis Siv
- Siv Dual 12V Ntsia Yog Ntau dua 20A
- Serial ATA Power Connectors Yuav Tsum Tau
- Cov Kev Hloov Hla Cov Hluav Taws Xob
24-Pin Lub Hwj Chim
Qhov no yog qhov tseem ceeb tshaj plaws rau kev hloov ATX12V. PCI Express tseev kom muaj 75 watt zog uas tsis tau muaj peev xwm nrog tus laus 20-pin connector. Ua lis no, 4 pins ntxiv tau ntxiv rau qhov sib txuas los muab lub zog ntxiv los ntawm 12V ntsia. Tam sim no tus pin layout yog keyed xws li tus 24-tus pin zog connector tuaj yeem siv rau cov laus ATX niam txiv nrog 20-pin connector. Tus caveat yog tias 4 lub tsho npav sab nraud yuav nyob rau sab ntawm lub hwj huam ntawm lub niam ntawv kom paub tseeb tias muaj ntau qhov tseeb rau lub pins ntxiv yog tias koj npaj rau kev siv ATX12V nrog rau cov laus ATX niam ntawv.
Dual 12V Ntsia
Raws li lub hwjchim xav tau ntawm cov txheej txheem, cov tsav tsheb thiab cov kiv cua yuav loj tuaj rau hauv lub cev, cov nqi ntawm cov khoom siv hluav taws xob los ntawm 12V txoj kab los ntawm lub hwj huam tau los kuj tseem. Thaum siab zog theem siab tab sis, lub peev xwm ntawm lub hwj huam mov los tsim ib qhov kev ruaj khov ruaj khov nyuaj dua. Yuav kom nyob rau qhov no, tus txheej txheem tam sim no yuav tsum muaj hwj huam khoom uas ua rau lub siab tshaj plaws high amperatge rau 12V kev tsheb nqaj hlau los ua phua rau ob qho kev cais 12V taw kev kom muaj kev ruaj ntseg. Muaj qee cov khoom siv hluav taws xob muaj hwjchim tseem muaj peb txoj kev tswjfwm 12V ywj siab kom muaj kev ruaj ntseg nce ntxiv.
Serial ATA Connectors
Txawm tias dhau Serial ATA connectors tuaj yeem nrhiav tau ntawm ntau ATX v1.3 cov khoom siv fais fab, lawv tsis yog ib qho yuav tsum tau ua. Nrog rau kev coj sai sai ntawm SATA drives, qhov kev xav tau rau cov connectors ntawm tag nrho cov khoom siv fais fab tshiab yuam tus txheej txheem kom yuav tsum muaj tsawg tus connectors ntawm lub hwj huam khoom siv. Laus ATX v1.3 units feem ntau tsuas yog muab ob zaug thaum tseem tshiab ATX v2.0 + cov khoom ntim plaub los yog ntau dua.
Fais fab Efficiency
Thaum cov hluav taws xob hloov tam sim no los ntawm lub qhov hluav taws xob qhov hluav taws xob qhov hluav taws xob mus rau sab nraud voltage qib xav tau rau lub tshuab computer, muaj feem ua txhua yam pov tseg uas yog kis tau rau hauv tshav kub. Yog li, txawm tias lub hwj huam mov yuav muab 500W ntawm lub hwj chim, nws yeej rub tawm ntau ntawm phab ntsa tshaj qhov no. Qhov ntsuas qhov fais fab kev txiav txim siab pom tau tias ntau npaum li cas lub zog tau rub tawm ntawm phab ntsa nrog rau qhov tso tawm rau hauv lub computer. Cov txheej txheem tshiab yuav tsum muaj qhov ntsuas qhov tsawg tshaj plaws ntawm 80%, tiam sis muaj ntau yam kev siab dua.
Cov lus xaus
Thaum yuav ib lub hwj chim, nws yog ib qho tseem ceeb uas yuav tsum muaj ib qho uas ua tau txhua yam ntawm lub zog ntawm lub tshuab computer. Feem ntau, cov qauv ATX yog tsim los kom rov qab tau tshaj qhov qub zog. Yog li, thaum mus yuav khoom rau ib lub hwj chim, nws yog qhov zoo tshaj los yuav ib qho uas tsawg kawg yog ATX v2.01 yuam lossis siab dua. Cov khoom siv fais fab no tseem ua haujlwm nrog cov laus hauv ATX uas siv 20-pin main power connector yog tias muaj chaw txaus.
