Lub zog siv hluav taws xob (PSU) yog ib qho ntawm ob peb yam hauv cov khoom siv hluav taws xob uas yuav cuam tshuam rau kev ntseeg tau ntawm koj lub cev tag nrho. Nws feem ntau yog qhov tsis txaus ntseeg tshaj plaws, tsis suav nrog hauv ib qho khoom siv twg, tseem yog ib qho ntawm thawj qhov ua rau ua tsis tau zoo.
Kab lus no tsom mus rau cov xwm txheej los saib thaum yuav PSU rau lub khoos phis tawj ntiag tug, tab sis nws tuaj yeem siv rau txhua daim ntawv thov xav tau kev tswj hwm PSU. Thaum ua raws phau ntawv qhia no, coj mus rau hauv tus account koj li kev thov, thiab tsim nyog ntsuas txhua qhov.
Cov kauj ruam
Kauj Ruam 1. Txheeb xyuas lub zog uas koj xav tau
Siv PSU lub laij lej lub vev xaib lossis software los pab txiav txim siab koj li kev xav tau. Txawm tias zoo dua yog nrhiav kev tshuaj xyuas cov txheej txheem zoo sib xws uas ntsuas kev siv hluav taws xob. Raws li qhov kev noj haus tau ntsuas ntawm phab ntsa, sib npaug los ntawm kev tshuaj xyuas cov txheej txheem cov khoom siv hluav taws xob kom tau txais txiaj ntsig. (Yog tias koj tsis paub, 0.82 yuav nyob ze lossis tsis zoo siab me ntsis.) Tsis txhob yuav PSU qhov siab tshaj qhov koj xav tau. Qhov ua tau zoo tshaj plaws ntawm txhua lub zog xa khoom yog nyob ntawm thaj tsam 40% -60% thauj khoom. Tsis tas li, PSUs hnub nyoog, poob hwj chim dhau sijhawm. Kev yuav PSU uas yuav coj koj mus dhau koj qhov kev hloov kho tom ntej no, nyob rau ntau xyoo.
Kauj Ruam 2. Tshawb nrhiav qhov txuas uas koj xav tau
Cov PSUs tshiab yuav feem ntau muab ob qho 24-pin ATX txuas uas ua ob npaug ua 20-tus pin txuas. Cov qauv siab dua yuav tsuas yog muab 24-tus pin txuas, thiab cov qauv qis kawg tuaj yeem muab tsuas yog 20 tus pin txuas. Feem ntau, feem ntau Pentium 4 thiab Athlon 64 CPU-based motherboards (thiab yav dhau los) yuav xav tau 20-tus pin ATX txuas, thaum cov niam ntawv tshiab xav tau 24-pin ATX txuas. Tsis tas li, feem ntau PSUs yuav muaj 4-tus pin txuas txuas 12V rau cov niam txiv, thiab qee qhov yuav muaj 8-tus pin uas ua ob npaug ua 4-tus pin thiab tsuas yog PSUs siab yuav muaj ib lossis ntau dua 6-tus pin lossis 8-pin PCI -E txuas rau daim npav video.
Kauj Ruam 3. Saib PSUs nrog kev ntsuas ua tau zoo
Thiab, cov ntsuas nyob hauv qab qhov ntsuas kub, tsis yog chav sov. Txhua yam 80% thiab siab dua yog qhov zoo. Ntawm 83%, kwv yees li 17% ntawm cov wattage poob vim cua sov. Yog li ntawd, PSU uas yuav tshaj tawm tias yog 500W PSU, yuav raug kos yuav luag 600W ntawm phab ntsa. Kev ua tau zoo poob qis rau lub sijhawm thiab thaum lub neej ntawm PSU. Ib xyoos PSU feem ntau yuav tsis muaj peev xwm tsim tau tib lub zog nws ib zaug ua thaum nws tshiab. Daim ntawv pov thawj "80 Plus" qhia tau tias lub zog hluav taws xob tau raug sim kom muaj 80% kev ua tau zoo ntawm txhua lub nra. Muaj qib siab dua ntawm 80 Ntxiv uas qhia tau tias muaj txiaj ntsig zoo dua li 80+ Bronze lossis Silver. Xav txog cov nqi hluav taws xob txuag, nws yuav tsim nyog yuav tau them tus nqi PSU ntau dua li qhov koj xav ua ntej.
Kauj Ruam 4. Txiav txim siab qhov muaj zog ntawm PSU
PSU tswj tau zoo npaum li cas txog kev hloov pauv tam sim no? Txawm hais tias tsis yog qhov lees paub, muaj kev sib raug zoo ntawm qhov hnyav thiab qhov zoo: cov khoom loj dua (piv txwv li, cov khoom siv hluav taws xob) sib npaug rau kev ua siab ntev, ntseeg tau PSU. Qhov no yog ib qho qis qis rau 120mm kiv cua: thaum nws ua kom txias txias dua, cov khoom kom txias yuav tsum tau ntim ntau dua. Yog tias koj tsis quav ntsej txog lub suab nrov, 80mm cua txias hauv qhov chaw ib txwm nyob tom qab ntawm PSU tuaj yeem muab tus nqi zoo dua.
Kauj Ruam 5. Txheeb tus naj npawb ntawm txoj kab
Ib yam li koj lub tsev fuse lub thawv suav nrog ob lub hauv paus loj thiab lub tshuab hluav taws xob me dua ib lub Circuit Court kom ntseeg tau tias cov kab hluav taws xob me me tsis ua kom sov, PSUs muaj peev xwm loj faib lawv cov zis rau ntau "ntsia," txhua qhov me me tam sim no txwv. Cov txheej txheem kev nyab xeeb cuam tshuam yuav tsum muaj 20A txwv, uas yog dav heev, muab tias cov xov hlau me dua li cov uas siv hauv koj lub tsev nqa 15A. (Tab sis muaj qhov zoo dua uas cov xov hlau tsis zais hauv phab ntsa, yog li lawv tau txias dua, thiab koj yuav hnov nws yog tias qee yam pib hlawv.) Qhov no, txawm li cas los xij, ua rau txuas PSU nyuaj dua; ntxiv rau kom tsis txhob hla nws tag nrho, koj yuav tsum zam dhau ntawm txhua txoj kev tsheb nqaj hlau, lossis nws yuav kaw. Lub zog hluav taws xob zoo yuav ua rau qhov yooj yim los ntawm kev muab cov ntsia hlau ntau dua li qhov ntsuas PSU tag nrho. Lwm txoj hauv kev pheej yig dua yog muab cov ntsia kom txaus rau tag nrho cov peev txheej, uas ua rau nws nyuaj rau siv tag nrho cov khoom siv hluav taws xob lub peev xwm. (Qhov no tej zaum yuav yog qhov tseeb tias PSU tsis muaj peev xwm xa nws lub peev xwm tag nrho.) Ib qho kev xaiv uas pheej yig dua, uas tau dhau los ua neeg nyiam, yog tshem tawm txhua qhov kev nyab xeeb kev nyab xeeb thiab tsim "ib-txoj kev tsheb nqaj hlau" fais fab mov uas tuaj yeem xa tag nrho nws cov txiaj ntsig ntawm ib qho xaim. Qhov no yog thev naus laus zis ua txhaum ATX-lub zog-kev qhia tshwj xeeb tab sis tsis tau ua pov thawj los ua teeb meem kev nyab xeeb hauv kev coj ua, thiab nyiam los ntawm ntau tus neeg. Kev tsim ib txoj kev tsheb ciav hlau tsis yog nws tus kheej yog lub cim ntawm PSU tsis zoo.
Kauj Ruam 6. Tau txais PSU modular
Nws yuav pab tshem tawm cov xov hlau ntxiv kom tau txais txoj hauv kev txias. Tsis quav ntsej cov lus foob tias cov kab hluav taws xob hloov pauv tsim kev tiv thaiv ntau dua vim kev xeb ntawm kev sib cuag. Qhov tsis kam ntxiv yog qhov tsis tsim nyog.
Kauj Ruam 7. Sib piv qhov amperage ntawm txhua qhov hluav taws xob
PSU qhov ntsuas hluav taws xob tsis zoo rau kev txiav txim siab amperage ntawm ib qho tshwj xeeb hluav taws xob. Txhua PSUs yuav muaj daim ntawv nplaum nrog lawv cov qhab nia ntsuas ntawm txhua qib hluav taws xob. Cov ntaub ntawv no yuav tsum tau muab thaum yuav PSU los ntawm tus muag khoom online thiab pom ntawm chav tsev lub khw muag khoom. Raws li tau hais los saum no, cov khoos phis tawj niaj hnub no yog 12V-hnyav. 500W PSU yuav zoo txaus, tab sis yog nws lub 12V amperage nyob hauv qis 20s lossis tsawg dua (12V zaug 25A yog 300W), nws yuav tsis tuaj yeem siv lub khoos phis tawj niaj hnub no.

High-powered 3D daim npav video thiab niam ntawv nrog 4-pin "P4" txuas los muab lub zog ua haujlwm, siv ntau qhov +12V lub zog, uas tsuas yog ib feem ntawm cov peev txheej ntawm cov khoom siv hluav taws xob qub. Txhawm rau kom ntseeg tau kev ua tau zoo, 3D cov duab tsim daim npav pom zoo cov khoom siv fais fab loj. Piv txwv li, 600W muab khoom kom ntseeg tau 300W ntawm +12V. Tus nqi tsim khoom tsim khoom, tig los, tsim cov khoom siv hluav taws xob sau tias "600W" uas tuaj yeem tsim tau 300W ntawm +12V, tab sis tsis ntau tshaj qhov ntawd, paub txog lawv cov neeg siv khoom yeej tsis tau thov lub zog ntxiv. Cov khoom siv hluav taws xob niaj hnub no yog txhua yam "12V hnyav" hauv txoj hauv kev no, tuaj yeem tsim tawm feem ntau ntawm lawv cov zis tag nrho hauv daim ntawv ntawm 12V, tab sis kev tshaj tawm cov khoom lag luam suav nrog tseem muaj ntau ntawm cov khoom siv hluav taws xob pheej yig dua; PSUs uas tuaj nrog rooj plaub tshwj xeeb yog qhov ua rau qhov no. Qee qhov PSU-suav software yuav suav nrog qhov "fudge factor" txiav txim siab los tso rau cov npe tsis raug no.
- Saib yav dhau los lub tswb-thiab-xuav, xws li lub teeb kiv cua, kho lub kiv cua nrawm, lub tes tsho, thiab pleev xim lossis pleev xim rau. Txawm hais tias cov no yog cov yam ntxwv xav tau tiag tiag, lawv tsis ua rau kev ua tau zoo lossis kev ntseeg tsis txaus.
- Muas tus PSU tester (feem ntau ntawm $ 10 thiab $ 20 US) kom paub meej tias txhua qhov kev tsheb nqaj hlau ua haujlwm ntawm koj li PSU tshiab. Nco ntsoov tias PSUs nrog 24 -tus pin txuas tsis muab -5V.
- Cov ntawv loj xws li Rosewill (hom Newegg lub tsev), muab tus nqi, tab sis tus nqi ntawm kev ua tau zoo thiab ntseeg tau. Cov ntawv sau zoo li no yog qhov kev xaiv zoo rau kev tsim qis nrog qhov xav tau lub zog tsawg, tab sis lawv feem ntau dhau rau lawv cov wattage tso tawm thiab tsis muaj kev tiv thaiv kom ntseeg tau zoo.
Lus ceeb toom
- Txheeb xyuas qhov lav. Sib piv txhua qhov chaw tsim khoom tau lees paub, txoj cai rov qab los, thiab keeb kwm kev pabcuam cov neeg siv khoom. Muaj qee tus PSU cov tuam txhab uas tso cov khoom lag luam zoo nrog kev txhawb nqa txaus ntshai, thiab rov ua dua.
- PSU cov chaw tsim khoom thiab cov xa khoom tsis muaj lub luag haujlwm rau ib qho txheej txheem ntawm kev ntsuas wattage. Ntau tus 'muaj txiaj ntsig' PSUs yuav tsis tuaj yeem tso tawm cov wattages uas lawv tau thov hauv ntiaj teb tiag. Nws muaj peev xwm rau 500W 'tus nqi' PSU los tsim lub zog qis dua li PSU zoo muag ntawm 350W. Yog li, 'kho dua tshiab' PSU tab sis xaiv tus qauv qis-kawg, tej zaum yuav yog qhov txo qis!
- Tsis txhob sim lub hwj chim muab nrog daim ntawv kaw. Qhov no txaus ntshai heev rau ob qho khoom siv thiab tus neeg siv vim tias daim ntawv kaw lus ua hluav taws xob.
