Yog tias koj lub PC muaj lub zog hluav taws xob ntsuas ntawm 500 watts, lub zog uas nws tau rub tawm ntawm phab ntsa qhov hluav taws xob tuaj yeem siab dua. Kawm paub yuav ua li cas PC fais fab mov efficiency cuam tshuam cov nqi hluav taws xob thiab yuav ua li cas txo koj cov nqi hluav taws xob nrog Energy Star khoom.
Cov ntaub ntawv hauv kab lus no siv dav rau ntau yam khoom siv. Txheeb xyuas qhov tshwj xeeb ntawm cov khoom lag luam ua ntej kev yuav khoom.
PC Power Supply Efficiency yog dab tsi?
Qhov kev ntsuas kev ua tau zoo ntawm lub zog hluav taws xob txiav txim siab npaum li cas lub zog hloov pauv los ntawm phab ntsa hluav taws xob hluav taws xob mus rau cov khoom siv hluav taws xob sab hauv. Piv txwv li, 75 feem pua ntawm cov khoom siv hluav taws xob ua haujlwm uas tsim 300W ntawm lub zog sab hauv yuav kos li 400W ntawm lub zog ntawm phab ntsa.
Thaum koj ntsaws koj lub computer rau hauv phab ntsa, qhov hluav taws xob tsis ntws ncaj qha mus rau cov khoom hauv lub computer. Cov hluav taws xob hluav taws xob thiab cov chips khiav ntawm qhov hluav taws xob qis dua li qhov tam sim no los ntawm phab ntsa qhov hluav taws xob. Yog li ntawd, cov khoom siv hluav taws xob yuav tsum hloov cov khoom siv 110 lossis 220-volts mus rau 3.3, 5, thiab 12-volt theem rau ntau yam hauv circuits. Lub hwj chim yuav tsum ua qhov no ntseeg tau thiab nyob rau hauv qee qhov kev zam kom tsis txhob ua rau lub cuab yeej puas.
Hloov cov voltages yuav tsum muaj ntau yam circuits uas poob zog thaum nws tau hloov dua siab tshiab. Qhov kev poob lub zog no feem ntau raug xa mus raws li cua sov rau lub hwj chim, uas yog vim li cas feem ntau cov khoom siv fais fab muaj cov kiv cua kom txias cov khoom.
kab hauv qab
Tus nqi npaum li cas nws txawv nyob ntawm tus nqi thauj khoom thiab qhov xwm txheej ntawm cov circuits. Kev ntsuas kev ua tau zoo dua txhais tau hais tias lub zog tsawg dua mus pov tseg, uas tuaj yeem cuam tshuam koj daim nqi hluav taws xob. Nws yog ib qho yooj yim los txheeb xyuas cov khoom siv hluav taws xob siv hluav taws xob hauv PC.
Lub Hnub Qub Zog thiab 80 Ntxiv Cov Khoom Siv Hluav Taws Xob
Lub Hnub Qub Zog tau tsim los ntawm EPA hauv xyoo 1992 raws li kev yeem daim ntawv sau npe tsim los qhia cov khoom siv hluav taws xob. Nws yog thawj zaug tsim rau cov khoom siv hauv computer los pab cov tuam txhab thiab cov tib neeg txo qis kev siv hluav taws xob.
Early Energy Star cov khoom lag luam tsis tas yuav ua kom tau raws li qib kev siv hluav taws xob nruj vim tias cov khoom lag luam tsis siv lub zog ntau npaum li lawv ua tam sim no. Rau cov khoom siv hluav taws xob tshiab thiab PCs kom tau raws li Lub Hnub Qub Zog, cov no yuav tsum ua tiav qhov kev ntsuas 85 feem pua ntawm txhua qhov ntsuas hluav taws xob tso tawm.
Thaum yuav khoom rau lub zog, nrhiav ib qho uas nqa 80 Ntxiv lub logo rau ntawm nws, uas qhia txog kev ua haujlwm ntawm 80 feem pua lossis siab dua. Qhov Kev Pabcuam 80 Plus muab cov npe khoom siv hluav taws xob uas yuav tsum tau ua raws li qhov yuav tsum tau ua.
Daim ntawv teev npe no tau hloov kho ib ntus thiab muab cov ntaub ntawv PDF rub tawm nrog cov txiaj ntsig kev xeem kom koj tuaj yeem pom raws nraim li cas cov khoom siv tau zoo. Muaj xya qib ntawm daim ntawv pov thawj xws li tsawg kawg mus rau qhov ua tau zoo: 80 Plus, 80 Plus Bronze, 80 Plus Silver, 80 Plus Kub, 80 Plus Platinum, thiab 80 Plus Titanium. Txhawm rau ua kom tau raws li Lub Hnub Qub Zog, cov khoom xav tau 80 Plus Silver ntsuas fais fab mov.
