Ukunikezelwa Kwamandla Okubili KwamaKhadi Wezithombe Nezingxenye Zangaphakathi
Ukunikezwa kwamandla okungeziwe kuyisimo esisheshayo emakethe ye-PC. Amandla amakhulu okushayela la madivayisi yilokhu okuqhubekayo ukusetshenziswa kwamandla amakhadi ehluzo e-PC . Amanye amakhadi wevidiyo manje athola amandla angaphezu kwaprosesa ohlelweni. Ngamanye amasistimu wokudlala anekhono lokugijima okungaphezu kweyodwa yalezi, akumangazi ukuthi ezinye izinhlelo zokusebenza zedeskithophu zingakwazi ukudweba okuningi njenge-kilowatt ephelele. Inkinga yukuthi ama-PC amaningi athengwa ngedeskithophu anempahla kuphela yamandla angu-350 kuya ku-500W. Yilapho ukunikezelwa kwamandla okungeziwe kungasiza.
Kuyini Ukunikezwa Kwemandla Engeziwe?
Ngokuyinhloko ukunikezwa kwamandla okwesibili okuhlala ngaphakathi kwikhompyutha yedokodo yedeskithophu ukunika amandla izingxenye ngokufaka amandla engeziwe amandla amaningi ohlelweni. Zakhiwe ngokujwayelekile ukuze zifinyelele ku-5.25-inch drive drive. Ikhebula lamandla angenayo ke lihanjiswe ngaphandle kwecala ngokusebenzisa i-slot ekhadini elitholakalayo ngemuva kwenkinga yesistimu. Izingcingo ezihlukahlukene zezinsimbi zigijima kusukela ekunikezeni amandla okungeziwe kuma-PC akho wangaphakathi.
Ukusetshenziswa okuvame kakhulu kulawa madivaysi ukunika amandla isizukulwane esisha samakhadi wehluzo wamandla alambile. Njengalokhu, cishe cishe banezici ze-PCI-Express ze-6-pin noma 8-pin ezixhunyiwe kuzo. Abanye futhi banezixhumi ezine-pin ze-molex kanye ne-Serial ATA amandla okuqhutshwa kwangaphakathi. Kungase kwenzeke ngisho ukuthola izinyunithi ezinezixhumi zamandla zamabhodi wamamayela, kodwa akuvamile.
Ngenxa yesikhala esinqunyelwe sezimpahla zamandla ezengeziwe, zivame ukuba zivinjelwe kakhulu emkhatsini wazo wonke amandla amakhulu uma kuqhathaniswa nokunikezwa kwamandla okujwayelekile. Ngokujwayelekile, zilinganiselwa ku-250 kuya ku-350 ama-watts okukhiphayo.
Kungani Usebenzisa Ukunikezwa Kwamandla Okungeziwe?
Inhloso eyinhloko yokufaka amandla okunikezwa amandla ngamandla lapho kuthuthukiswa isistimu yekhompyutha yedeskithophu ekhona. Ngokuvamile, lokhu kungukuthi ikhadi le-graph elamandla elinamandla lifakwe ohlelweni olungenalo okwenziwe kahle kwamanzi ukuze lisekele ikhadi lehluzo noma lingekho amandla okuxhuma amandla okusebenzisa amakhadi ahluzo. Zingasetshenziswa futhi ukuhlinzeka ngamandla engeziwe ezingxenyeni zangaphakathi ezifana nalabo abafuna ukusebenzisa inombolo enkulu yezinkinobho ezinzima.
Yiqiniso, kungenzeka ukufaka esikhundleni sokunikezwa kwamandla okukhona ohlelweni olusanda kukhethwa kwamanzi amaningi, kodwa inqubo yokufaka amandla okungeziwe ngokujwayelekile ngokuvamile elula kuneyunithi eyinhloko. Kukhona namanye amasistimu ekhompuyutha wedeskithophu asebenzisa ukuklanywa kwamandla okusebenza okungahambisani nokunikezwa kwamandla wedeskithophu jikelele endaweni yawo. Lokho kwenza ukunikezwa kwamandla okungeziwe kube yindlela enhle kakhulu yokwandisa amandla okusebenza ngaphandle kokuyivuselela ngokuphelele.
Izizathu Zokuthi Ungasebenzisi I-Supplemental Power Supply
Izimpahla zamandla ziyi-generator enkulu yokushisa ngaphakathi kwamakhompiyutha. Ama-circuits ahlukahlukene asetshenziselwa ukuguqula udonga lwamanje phansi kwezingcingo eziphansi zamandla ngaphakathi kwesistimu kudala ukushisa njengomkhiqizo. Ngokunikezwa kwamandla okujwayelekile, lokhu akuyona inkinga enkulu njengoba iklanyelwe ukuphuma emoyeni naphandle kweso. Njengoba amandla e-supplemental ahlala ngaphakathi kulolu cala, kuvame ukudala ukwakheka kokushisa okungaphezulu ngaphakathi kweso.
Manje, ezinye izinhlelo lokhu ngeke kube inkinga uma sebevele bepholile ngokwanele ukusingatha ukwakhiwa kokushisa okungaphezulu. Ezinye izinhlelo ngeke zikwazi ukubhekana nalokhu okushisa okungaholela ekutheni uhlelo luvalwe ngenxa yokubekezelelana nokushisa noma ukulimaza okungase kube khona emiphakathini. Ikakhulukazi, amacala edeskithophu afihla ama-drive angama-5.25-intshi ngemuva komnyango kufanele agweme ukusebenzisa imithombo yamandla engeziwe. Isizathu sukuthi ukupholisa kuklanyelwe ukudonsa umoya kusukela ngaphambili kwe-bay drive ngokusebenzisa ukunikezwa kwamandla okuphelelwa yisikhathi kulolu cala. (Kungase futhi kugeleke ngenye indlela kuye ngokuklama.) Iphaneli lomnyango elivimbela isembozo sangaphambili sezintaba zokushayela kuzovimbela ukugeleza okwanele komoya futhi kuyoba nomthelela omkhulu wokushisa uhlelo.
Ingabe Kufanele Uthole Ukunikezwa Kwamandla Amandla?
Lezi zinyunithi zisebenzela inhloso kwabanye abantu ababuka ukuthuthukisa uhlelo lwedeskithophu oludinga amandla okufaka. Lokhu kuyiqiniso ikakhulukazi uma abasebenzisi bengenaso isiqiniseko uma bengakwazi ukususa futhi bashintshe ukunikezwa kwamandla okukhona okunamandla kakhulu ngaphakathi kwecala labo. Kungenzeka ukuthi ukunikezwa kwamandla kufakwe ngendlela enzima ukususa noma ngoba uhlelo lusebenzisa indlela yokunikezwa kwamandla kagesi. Uma ideskithophu yakho isebenzisa umklamo wokunikezwa kwamandla okujwayelekile futhi ingashintshwa, kungcono kakhulu ukuthola nje inyunithi enamandla futhi ukufaka lokho ngaphezu kwesinye.
