Dab tsi yog fais fab mov thiab dab tsi yog rau?
Cov khoom siv fais fab txuas hluav taws xob (PSU) yog ib qho khoom siv rau kev hloov hluav taws xob loj (220 volts) rau cov kev cai teev cia. Yuav pib nrog, peb yuav txiav txim siab los ntawm cov txheej txheem dab tsi koj tuaj yeem xaiv lub hwj huam hluav taws xob rau koj lub khoos phis tawm, thiab tom qab ntawd peb yuav txiav txim siab qee cov ntsiab lus hauv ntau dua.
Qhov tseem ceeb thiab qhov kev xaiv tseem ceeb tshaj plaws (PS) yog lub zog tshaj plaws uas yuav tsum tau los ntawm cov koos pij tawj, uas ntsuas rau hauv cov hwj chim uas hu ua Watt (W, W).
Kwv yees li ntawm 10-15 xyoo dhau los, rau kev ua haujlwm ntawm ib lub computer nruab nrab, tsis pub ntau tshaj 200 watts, tab sis nyob rau peb lub sijhawm no tus nqi tau nce, vim yog qhov tshwm sim ntawm cov tshiab uas siv ntau lub zog.
Piv txwv li, ib daim SAPPHIRE HD 6990 daim npav daim duab tuaj yeem haus tau txog li 450 watts! I.e. Txhawm rau xaiv cov hluav taws xob tsis txaus, koj yuav tsum txiav txim siab ntawm cov Cheebtsam thiab nrhiav kom paub seb lawv lub zog noj dab tsi.
Cia peb saib qhov piv txwv ntawm yuav ua li cas xaiv PSU (ATX):
- Processor - 130 W
- -40W motherboard
- Nco -10 W 2pcs
- HDD -40 W 2pcs
- Daim npav video -300 W
- CD-ROM, CD-RW, DVD -2 0W
- Lub thawv txias - 2 W 5pcs
Yog li, ntawm no yog cov npe nrog cov cheebtsam thiab lub zog siv hluav taws xob los ntawm lawv, txhawm rau suav lub zog ntawm PSU, koj yuav tsum ntxiv lub zog ntawm txhua qhov, thiab + 20% rau cov Tshuag, i.e. 130 + 40 + (20) + (80) + 300 + 20 + (10) = 600. Yog li, lub zog tag nrho ntawm cov khoom siv yog 600 watts + 20% (120 W) = 720 watts i.e. rau cov khoos phis tawj no, muaj kev siv fais fab tsawg kawg 720 W.
Peb xam lub zog, tam sim no cia peb sim tawm qhov zoo: nws yog qhov muaj zog, nws tsis txhais tau tias tsis zoo. Niaj hnub no nyob rau hauv kev ua lag luam muaj ntau ntau ntawm cov khoom siv fais fab los ntawm pheej yig npe mus rau lub npe nrov heev. Kev siv hluav taws xob zoo kuj tseem nrhiav tau ntawm cov pheej yig: qhov tseeb yog tias tsis yog txhua lub tuam txhab ua PSUs lawv tus kheej, raws li kev coj ua nyob rau hauv Suav teb, nws yooj yim dua rau kev coj thiab ua qee lub chaw tsim khoom raws li cov phiaj xwm npaj, thiab qee qhov ua tau zoo heev, yog li kev tsim nyog tuaj yeem ntsib txhua qhov chaw, tab sis yuav ua li cas thiaj paub tsis tas qhib lub thawv yog cov lus nug nyuaj.
Txawm li cas los xij, koj tuaj yeem tawm tswv yim txog kev xaiv lub zog ATX fais fab: lub PSU zoo tsis tuaj yeem hnyav dua 1 kg. Ua tib zoo saib cov cim hlau (xws li hauv daim duab) yog tias 18 awg tau sau nyob rau ntawd, tom qab ntawd qhov no yog tus qauv yog tias 16 awg, tom qab ntawv qhov no zoo heev, tab sis yog 20 awg, tom qab no cov no twb tau txais txoj xov hlau qis, koj tuaj yeem hais tau tias kev sib yuav.
Ntawm chav kawm, nws zoo dua tsis txhob ntxias txoj hmoo thiab xaiv lub BP ntawm cov tuam txhab pov thawj, muaj ob qho kev lees paub thiab hom. Hauv qab no yog cov npe npe ntawm cov paub zoo ntawm cov khoom siv fais fab:
- Zalman
- Ntsuas Kub
- Keeb Kwm
- Khub
- Fsp
- Delta zog
Muaj lwm qhov ntsuas - qhov loj me ntawm lub hwj huam hluav taws xob, uas yog nyob ntawm daim ntawv foos ntawm rooj plaub uas nws yuav raug teeb tsa, thiab lub zog ntawm PSU nws tus kheej, qhov tseeb tag nrho cov khoom siv fais fab yog ATX tus qauv (pom hauv daim duab hauv qab no), tab sis muaj lwm lub PSU uas tsis siv rau qee cov qauv.
