Ukuqonda i-PC PSU Ukunyuka kwamanani ukuqiniseka ukuba unamandla aneleyo
Okuninzi kunikwe amandla onke kwiimarike kwikhompyutheni yePC desktop ikhangelwe kuphela kwi-wattage yayo. Ngelishwa, le ngcamango elula yenkinga enzima kakhulu. Ukunikezelwa kwamandla kukho ukuguqula umbane ophezulu ukusuka kwidonga lokudonga kwimigangatho engezantsi efunekayo ukuqhuba ii-computer zombane. Ukuba oku kungenziwa ngokufanelekileyo, izibonakaliso zamandla ezingaqhelekanga ezithunyelwa kumacandelo zingenza umonakalo kunye nokungazinzi kwenkqubo. Ngenxa yoko, kubalulekile ukuqinisekisa ukuba uthenge ukunikezelwa kwamandla okuhlangabezana neemfuno zekhompyutha yakho.
I-Peak ne-Maximum Wattage Output
Le yinto yokuqala ye-gotcha enkulu xa ifika ekujongeni ukunikezelwa kwamandla kagesi. Umlinganiselo wokuphakanyiswa komlinganiselo ngowona mgangatho ophezulu wamandla iyunithi inokunikezela kodwa oku kuphela nje ixesha elifutshane. Amanyano akakwazi ukuqhubeka nokubonelela amandla kule nqanaba kwaye ukuba uzama ukwenza njalo kuya kubangela umonakalo. Ufuna ukufumana ubungakanani obuphezulu bokusetyenziswa kwamanzi obonelelo. Eli lixabiso eliphezulu ukuba inyunithi ingakwazi ukubonelela ngokucacileyo kumacandelo. Ngaloo nto, ufuna ukuqinisekiswa ukuba ukulinganiswa kwamanzi amaninzi kuphezulu kunokuba uzimisele ukuyisebenzisa.
Enye into ekufuneka uyiqaphele ngokuveliswa kwamanzi ihambelana nendlela ibalwa ngayo. Kukho iiprayimari ezintathu zokuqala zamandla ngaphakathi kwonikezelo lwamandla: + 3.3V, + 5V kunye + 12V. Ngamanye kwezi zinto zinika amandla kwiinkalo ezahlukeneyo zekhompyutha. Ingumlinganiselo wendlela yamandla ehlanganisiweyo kuwo wonke lo mgca owenza isiphumo samandla esiphezulu sokunikezelwa kwamandla. Ifomula esetyenziswe ukwenza oku:
- Amanzi = I-Voltage * Amperage
Ngoko ke, ukuba ukhangela ityhilo yokunikezelwa kwamandla kwaye ibonisa ukuba umgca we-12V uhlinzeka nge-18A yamandla, ukuba umzila wesitimela unokunikezela ngamandla angama-216W. Oku kunokuba yiqhezu elincinci kuphela lithetha i-450W ukunikezwa kwamandla ku-rated. Imveliso ephezulu ye-+ 5V kunye ne-3.3V iinqwelo ziza kubalwa ize zongezwe kumlinganiselo wokubasa amanzi.
& # 43;
Umzila wesitimela obaluleke kakhulu kwi-supply supply yi-12V yesitimela. Lo mzila wesitimela unika amandla kumacandelo atshabalalayo aquka umprojekti, umqhubi, abalandeli bokupholisa kunye namakhadi amifanekiso. Zonke ezi zinto zidweba ezininzi zamanje kwaye ngenxa yoko ufuna ukuqiniseka ukuba uthenge ityunithi enika amandla okwaneleyo kwisitimela se-12V.
Ngeemfuno ezikhulayo kwimida ye-12V, amaninzi amatsha enamandla aneemitha ezili-12V eziya kubalwa njenge-12V1, + 12V2 kunye ne-12V3 kuxhomekeka ukuba ngaba iireyili ezimbini okanye ezintathu. Xa ubala i-amps yomgca we-12V, kuyimfuneko ukujonga i-amps ezipheleleyo ezivelisa kuzo zonke iiprola eziyi-12V. Amaxesha amaninzi kunokuba nombhalo wamagama angaphantsi ukuba ukudibanisa umthamo ophezulu kuya kuba ngaphantsi kwexabiso elipheleleyo lemilayezo. Mane uguqule umgaqo olapha ngentla ukuba ufumane ama-amp amps.
- Amperage = Amanzi / I-Voltage
Ngolu lwazi malunga neer + 12V, umntu angayisebenzisa ngokubhekiselele ekusebenziseni amandla jikelele ngokusekelwe kwinkqubo yenkqubo. Nazi iinqununu zemizila engaphantsi kwee-12V (kunye ne-PSU yokulinganisela umthamo wamanzi) kwiinkqubo ezahlukeneyo zeekhompyutha:
- Icandelo leFomu elincinci - 15A (250W)
- I-Mini-Tower - 25A (300-350W)
- I-Mid-Tower - 35A (400-500W)
- I-Tower Tower - 40A (600-650W)
- Ikhadi leVidiyo yeeDual (SLI) - 50A (750W +)
Khumbula ukuba ezi ziyiziphakamiso kuphela. Ukuba unamalungu athile alambileyo, hlola iimfuno zokubonelela amandla kunye nomenzi. Amakhadi amaninzi amanqaku aphezulu adibanisa i-200W eyedwa phantsi komthwalo opheleleyo. Ukuqhutywa ezimbini kwamakhadi kunokufuna lula ukunikezelwa kwamandla okungagcina ubuncinane ubuncinane be-750W okanye ngaphezulu kwesiphumo samandla.
Ingaba Ikhompyutha Yami Ingayisebenzisa?
Ndihlala ndifumana imibuzo kubantu abafuna ukuphucula amakhadi abo abonisa imifanekiso kwikhompyutheni yabo yecomputer. Amakhadi amaninzi asekupheleni kweemifanekiso aneemfuno ezichanekileyo zamandla ukuze kusebenze kakuhle. Ngombulelo oku kuphuculwe kunye nabakhiqizi ngoku babeka uluhlu lwazi. Uninzi luya kuluhlu nje uluhlu lwamanzi olutyekisiwe lwonikezelo lwamandla kodwa okona luhle xa lubhala inani elincinci le-amps ezifunekayo kumgca we-12V. Ngaphambili awakhuphanga naziphi na iimfuno zokunikezelwa kwamandla.
Ngoku, ngokweekhompyutha ezininzi zekhompyutha, iinkampani ngokubanzi azibhalisanga iziphumo zokunikezelwa kwamandla kwi- PC kwiinkcukacha zabo. Ngokuqhelekileyo umsebenzisi uya kufuneka avule imeko kwaye afune iileyile yokunikezelwa kwamandla ukucacisa ukuba yintoni na inkqubo inokuxhasa. Ngelishwa, ii-PC ezininzi zee desktop ziza kunye nokunikezelwa kwamandla aphantsi njengendlela yokulondoloza indleko. I-PC esebenzayo ye-PC engazange ifike ngekhadi lemifanekiso eqingqiweyo iya kuba neyunithi phakathi kwe-300 ukuya ku-350W iyunithi nge-15A ukuya ku-22A. Oku kuya kuba kuhle kumakhadi ahlulo-bhajethi, kodwa amaninzi emakhadi ehlulo-bhajethi ayenyuka kwiimfuno zabo zamandla apho bengayi kusebenza khona.
Izigqibo
Khumbula ukuba yonke into esiye sathetha ngayo ibandakanya imida ephezulu yonikezelo lwamandla ekhompyutha. Mhlawumbi i-99% yexesha ikhompyutha isetyenzisiweyo, ayinakuthatyathwa ekubakho ubuninzi kwaye ngenxa yoko iza kuba namandla angaphantsi kwamaqondo. Into ebalulekileyo kukuba ukunikezelwa kwamandla kwikhompyutheni kufuneka kube nekamelo elaneleyo lala maxesha ukuba inkqubo ihlawuliswe kakhulu. Imizekelo yezo zihlandlo idlala imidlalo ye-3D ebonakalayo okanye yenza i-video transcoding. Ezi zinto zikarhafisa iirhafu kwaye zifuna amandla angaphezulu.
Njengokuba kunjalo kwinqanaba, ndibeka imitha yokusetyenziswa kwamandla phakathi kokunikezelwa kwamandla kunye nelokudonga kwidonga kwikhompyutyana njengolu vavanyo. Ngethuba lekhompyutheni eliqhelekileyo, inkqubo yam yayinokungena kwi-240W yamandla. Oku kungaphantsi kwexabiso lokubonelela kwam amandla. Nangona kunjalo, ukuba ndidlala umdlalo we-3D iiyure eziliqela, ukusetyenziswa kwamandla kuphakama phezulu ukuya kwi-400W yamandla onke. Ngaba oku kuthetha ukuba ukunikezelwa kwamandla angama 400W kuya kukwanela? Mhlawumbi kungekhona njengoko ndinenani elikhulu lezinto ezithatha kakhulu kwi-railway ye-12V kangangokuthi i-400W ingaba neengxaki zombane eziza kubangela ukungazinzi kwenkqubo.
