To taub PC PSU Wattage Ratings los ua kom koj muaj lub zog txaus
Zoo nkauj npaum txhua lub hwj huam mov ntawm lub lag luam rau ib lub computer PC lub computer yog tshaj tawm rau nws cov wattage. Hmoov tsis, qhov no yog ib qho kev simplistic saib ntawm ib qho teeb meem heev. Lub hwj huam yog los hloov lub siab ntawm qhov hluav taws xob ntawm qhov hluav taws xob rau sab nraud qhov yuav tsum tau khiav ntawm lub computer circuitry. Yog tias qhov no tsis ua tiav zoo, cov lus ceeb toom xiam oob khab uas raug xa mus rau lwm tus tuaj yeem ua rau puas tsuaj thiab tsis muaj teeb meem. Vim li no, nws yog ib qho tseem ceeb kom paub tseeb tias koj yuav lub hwj chim ua tau raws li qhov xav tau ntawm koj lub computer.
Peak thiab Maximum Wattage Output
Qhov no yog thawj zaug tau txais txiaj ntsig loj thaum nws tuaj xyuas ntawm lub hwj huam qhia txog khoom. Qhov ntsuam xyuas qhov siab tshaj plaws yog qhov siab tshaj plaws ntawm lub hwj chim hauv chav tsev yuav muab khoom tab sis qhov no tsuas yog rau ib lub sijhawm luv. Cov chav nyob tsis tuaj yeem muab lub hwj chim rau ntawm theem no thiab yog nws sim ua li ntawd yuav ua rau kev puas tsuaj. Koj xav nrhiav qhov siab tshaj qhov ntsuas ntawm qhov fais fab. Qhov no yog qhov siab tshaj plaws uas tus neeg tuaj yeem tuaj yeem ruaj ntseg rau lub cheebtsam. Txawm nrog qhov no, koj xav kom paub tseeb tias qhov siab tshaj plaws ntawm kev ntsuam xyuas yog siab dua koj xav siv.
Ib qho ntxiv uas yuav tsum tau ras txog nrog cov qhov tso tawm wattage tau ua li cas nws yog xam. Muaj peb yam khoom hluav taws xob hauv lub hwj chim: + 3.3V, + 5V thiab + 12V. Txhua yam ntawm cov khoom siv no muaj feem xyuam rau ntau yam ntawm lub tshuab computer. Nws yog qhov ua ke tag nrho cov hluav taws xob cov zis ntawm tag nrho cov kab no uas ua rau tag nrho cov zog tso tawm ntawm lub hwj chim. Cov qauv siv los ua qhov no yog:
- Watta = Voltage * Amperage
Yog li, yog tias koj saib ntawm lub hwjchim rau daim ntawv lo thiab nws qhia tau hais tias lub + 12V kab khoom siv 18A ntawm lub hwj chim, qhov kev taw qhia hluav taws xob muaj peev xwm tshaj plaws ntawm 216W ntawm lub zog. Qhov no tej zaum yuav yog ib feem me me ntawm cov lus hais tias 450W ntawm lub hwj huam yog nyob ntawm. Qhov siab tshaj plaws ntawm cov khoom 5V thiab cov 3.3V ntsia hlau yuav ces xam tau thiab ntxiv rau kev ntsuam xyuas txhua yam.
& # 43; 12V Rail
Qhov tseem ceeb tshaj ntawm cov tsheb ciav hlau nyob hauv lub hwj huam yog 12V tsheb ciav hlau. Cov khoom siv hluav taws xob ntawm cov hluav taws xob no muaj hwj chim rau cov khoom siv coob tshaj plaws nrog rau tus neeg ua haujlwm, cov twj paj nruag, cov kiv cua txias thiab cov duab cim. Tag nrho cov khoom no kos ntau ntau tam sim no thiab vim li ntawd koj xav kom paub tseeb tias koj yuav ib chav tsev uas muaj khoom txaus rau lub 12V tsheb ciav hlau.
Nrog rau kev xav tau ntawm 12V kab, ntau lub hwj huam tshiab muaj ntau yam 12V ntsia uas yuav teev tau li 12V1, + 12V2 thiab 12V3 nyob ntawm seb nws puas muaj ob los yog peb txoj kab. Thaum ntsuas cov amps rau + 12V kab, nws yog qhov yuav tsum tau saib ntawm cov amps tag nrho tawm ntawm tag nrho cov 12V ntsia. Feem ntau cov sij hawm yuav muaj taw qhia tias qhov sib txuas ua ke ntau tshaj plaws yuav tsum tsawg tshaj qhov ntsuas ntawm txoj kab. Cia li rov qab rau cov qauv saum toj no kom tau txais cov nyiaj ntau tshaj ua ke.
- Amperage = Wattage / Voltage
Nrog cov ntaub ntawv no txog kev siv + 12V, ib tug siv tau nws tawm tsam kev siv hluav taws xob raws li lub kaw lus ntawm lub system. Ntawm no yog cov lus pom zoo rau qhov tsawg kawg nkaus 12V txoj kev tsheb ciav hlau (thiab lawv cov txheeb ze PSU tus qauv ntsuas) rau ntau hom kev siv computer:
- Tsab Ntawv Me Muaj - 15A (250W)
- Mini-Ntauwd - 25A (300-350W)
- Mid-Tower - 35A (400-500W)
- Puv ntauwd - 40A (600-650W)
- Dual Video Card (SLI) - 50A (750W +)
Nco ntsoov tias cov no tsuas yog kev pom zoo. Yog tias koj muaj lub hwj chim tshwj xeeb tshaib plab, xyuas cov khoom siv hluav taws xob nrog lub khw. Muaj ntau qhov kawg graphics cov ntawv teev lus yuav rub tau ze 200W ntawm lawv tus kheej nyob rau hauv tag nrho cov load. Khiav ob ntawm cov ntawv teev lus tau yooj yim kom muaj lub hwj huam khoom uas tuaj yeem txhawb nqa yam tsawg 750W los yog tshaj ntawm tag nrho cov zis hluav taws xob.
Puas Yog Kuv Lub Computer Tuav Qhov No?
Kuv nquag tau txais cov lus nug los ntawm cov neeg uas tab tom nrhiav kom tau upgrade lawv daim card graphics hauv lawv lub computer system. Muaj ntau cov ntawv qib high-end graphics muaj cov tseev kom muaj rau lub hwj chim kom ua haujlwm zoo. Thankfully qhov no tau zoo tuaj nrog cov kws ua lag luam tam sim no teev tej ntaub ntawv. Feem ntau yuav cia li sau tag nrho cov nqi zog ntawm cov hwj huam tiam sis qhov zoo tshaj plaws yog thaum lawv sau tsawg npaum li cas ntawm cov amps uas yuav tsum tau siv rau 12V kab. Yav tas los lawv tsis tau luam tawm cov lus fais fab twg.
Tam sim no, nyob rau hauv cov nqe lus ntawm feem ntau cov computers, cov tuam txhab feem ntau tsis sau lub PC lub hwj huam mov kev nyob rau hauv lawv cov specifications. Feem ntau tus neeg siv yuav tsum qhib rooj plaub thiab nrhiav lub hwj foos daim ntawv lo cim los txiav txim siab li cas raws nraim qhov system yuav pab txhawb. Hmoov tsis, feem ntau cov PCs tuaj yeem nrog cov khoom siv fais fab tsawg tsawg li kev txuag nyiaj. Ib tug qauv duab PC uas tsis tuaj nrog daim npav xaiv nplooj siab yuav muaj ntawm 300 txog 350W nrog rau 15 mus rau 22A kev ntsuam xyuas. Qhov no yuav zoo rau qee cov peev nyiaj qiv nyiaj txiag, tab sis ntau daim npav peev nyiaj tau nce hauv lawv lub hwj chim xav tau qhov twg lawv yuav tsis ua haujlwm.
Cov lus xaus
Nco ntsoov tias txhua yam peb tau tham txog yuav tsum muaj kev txwv ntau tshaj ntawm lub tshuab fais fab. Tej zaum 99% ntawm lub sijhawm siv lub koos pis tawj, nws tsis raug siv rau qhov nws muaj peev xwm tshaj plaws thiab vim tias nws yuav tsis muaj hwj chim ntau dua li qhov siab tshaj. Qhov tseem ceeb tshaj plaws yog tias lub tshuab hluav taws xob lub computer yuav tsum muaj lub taub hau kom txaus rau cov sij hawm uas lawv raug them se ntau. Piv txwv ntawm cov sij hawm xws li ua si nrig 3D ua si los yog ua video transcoding. Tej yam no yuav tsum tau them se feem ntau thiab yuav tsum muaj hwj chim ntxiv.
Ua ib qho teeb meem hauv qhov taw tes, kuv muab lub hwj chim ntsuas ntawm lub hwj chim thiab lub qhov hluav taws xob rau ntawm kuv lub computer ua ib qho kev sim. Thaum lub sij hawm nruab nrab, kuv lub cev tau rub tsis tau tshaj 240W ntawm lub hwj chim. Qhov no zoo li hauv qab qhov ntsuam xyuas ntawm kuv lub hwj chim. Txawm li cas los xij, yog hais tias kuv mam li ua si 3D kev ua si rau ob peb xuab moos, lub hwj huam pab nce siab mus rau ntawm 400W ntawm tag nrho cov hwj huam. Qhov no puas txhais tau tias qhov khoom siv hluav taws xob 400W yuav txaus? Tej zaum tsis yog li kuv muaj ntau qhov khoom uas ua rau hnyav ncawv rau ntawm 12V tsheb nqaj hlau xws li tias ib qho 400W muaj teeb meem qhov teeb meem uas yuav ua rau muaj kev tsis sib haum xeeb.
