Amandla kagesi kukhompyutha. Indlela yokwenza izinqumo ezinhle?

Amandla Iyunithi enikeza - lena imininingwane ye-computer lapho kuncike ngqo ukuthembeka kukhompyutha yakho, futhi ngaphezu kwakho konke, ukuthembeka HDD - hard disk drive, okuyinto igcina yonke imininingwane. Eqinisweni, ngaphandle kwamandla ngisho best kukhompyutha 'nensimbi' ayikwazi ukusebenza ngaso sonke - lena ingxenye obhekene supply computer izingxenye kanye namandla-ukuguqulwa oza ikhompyutha kunethiwekhi kuya wayefisa ngabanye ISIZINDA ikhompyutha.

Kubalulekile ukukhumbula ukuthi ngaphezu umsebenzi walo esiyinhloko okuphakela amandla computer somthetho voltage nesihlangu kusukela komncane umsindo okokufaka voltage, futhi nawo uhilelekile kule Ukupholisa unit uhlelo.

Kulezi zinsuku, cishe zonke PC zanamuhla amayunithi esetshenziswa ezifana ukunikezela ATX. Kuqhathaniswa amayunithi amadala ohlobo AT, ATX has a ephakeme okungenani zamanje. Lokhu kungenxa yokuthi izingxenye amakhompyutha zanamuhla kudla ugesi okuningi futhi zidinga misinga enamandla ngaphezulu ukuze lusebenze kahle.

Okubaluleke kakhulu, yini okumelwe siyibheke lapho ukhetha amandla supply for computer kuyinto amandla aso nesihlalo Ukucaciswa eziyisisekelo. amandla adingekayo yekhompyutha ngamunye uhlukile futhi kuncike ukumiswa kwe-computer, kanye degree of yinkimbinkimbi uhlelo ngokuyinhloko. Ngokwesibonelo, imishini yokudlala noma ukusebenza okuphezulu workstations zidinga amandla ephakeme kunaleyo ezisekelweni esishunyekiwe izici ezincane fomu.

Esinye isici esibalulekile, esesikhundleni kwamandla ikhompyutha, lokhu Imininingwane wamanje, ikhiqizwa PD okukhiphayo. Nokho, abanye abakhiqizi ukukhiqiza ugesi amayunithi enentambo olulodwa, futhi ngezinye izinto amandla zihlanganisa imigqa emibili noma ezine kanye lapho notshwala samanje, futhi inani lemigqa ngezinye izikhathi kwakuba khona cishe akunamthelela ukusebenza kwe-kwamandla.

Ngaphambi kokuthenga amandla supply kubaluleke kakhulu ukubala ukuthi angakanani amandla Uzodla ikhompyutha cishe siqu lapho lokhu amandla Iyunithi enikeza lizofakwa. Futhi isici yokugcina kokukhetha le ngxenye kufanele kubhekwe izici eziyinhloko zalo (umthamo futhi amandla jikelele wamanje) hhayi ukusebenza ezengeziwe. Ngokwesibonelo, uma unquma ukhethe kangako kodwa noiseless amandla Iyunithi enikeza kwikhompyutha ngokuhamba kwesikhathi, ungase uzisole lokho kukhetha - ngemuva kokufaka ezengeziwe inkumbulo strip noma angaphezu kwelilodwa hard drive udinga ukuthenga ugesi namandla kakhulu. Ukuze uthole ikhompyutha ukuthi umsebenzisi uhlose ukusebenzisa iminyaka eminingi, ungakwazi ukuthenga PSU ne inqolobane encane amandla nje, uma ngokuhamba kwesikhathi ikhompyutha ingeke ukuthenga imininingwane eyengeziwe.

izici engeziwe nibaluleke ukunaka lapho kukhethwa kwamandla, kuba, okokuqala kunakho konke, Cable Management Namandla Factor Ukulungiswa. Ikhebula Management - leli yithuba Ukukhipha izintambo ubuningi, okuvumela ekusetshenzisweni ngokugcwele kuluthola ugesi. Amandla Factor Ukulungiswa (ngokwezwi nezwi ehunyushwa ngokuthi njengoba "amandla isici ukulungiswa") kuyinto ezimbili zama - yekwentiwa. PFC Passive umane smoothes le pulses zamanje, kancane esisuka kubo ngokuhamba kwesikhathi. Active PFC kwalokho uyakwazi ukunikeza amandla isici, okuyinto eduze ekahle. Ngenxa yalokho, amandla supply for computer izosebenzisa amandla enawo esiphezulu.

Kodwa bonke ngokufana ukukhetha okungcono ugesi ngenxa computer? Ukuze wenze lokhu, ukuhlola imisebenzi ozibekela kukhompyutha yakho, futhi balinganisela olunzima amandla ukusetshenziswa kwazo zonke izingxenye PC futhi vele ukhethe lunikeza izibalo imodeli etholwe. Phakathi Abenzi segezi Kumele kuqashelwe ezifana abadlali computer emakethe njenge FSP, Zalman, Asus, Chieftec futhi @LUX. Kuye umenzi kanye imodeli izici ezikhethiwe, ugesi izindleko kungaba isukela amabili kuya dollar angamakhulu amabili.
