Indlela ukukhetha neyunithi umbane uze uwaqobe iingalo

Uninzi (ukuba yonke) wathengisa izinto amandla computer Abizelwa e-China. Kakade ke, amazwi athi "China China - ingxabano" ayenziwanga irhoxisiwe, kodwa umgangatho ubuninzi ezi zixhobo, makayixhome ngokuzolileyo, esezantsi. Le nyaniso akukho namnye ubusithelisayo, ngoko ngokufuthi yaphakamisa umbuzo ukuba ukhethe njani unikezelo amandla. Ngaphezu koko, abenzi nokuba sidume badla siyabonisa ukuba olunyuswe ngama-20 ekhulwini amaxabiso ulinganise lwangoku. Enyanisweni, ukuba ziyalandeleka, kuba xa kujongwa ukhuphiswano emarikeni bungwanyalala, zonke iindlela ezilungileyo ukusinda, kodwa yintoni umsebenzisi ... lisahleli sihlolisise kakhulu idatha yokundwendwela kwezixhobo kunye ukuqonda kakuhle ukuba ukhethe njani unikezelo lwamandla ye computer. Yiloo nto thina namhlanje yaye siza sithethe.

Iyunithi amandla supply kwi kwisisu semoto kwaye ibonelela ngamandla onke amacandelo. Ngokubanzi, umsebenzi wayo ilula kwaye kudala isonjululwe ngempumelelo Electrical: zolimo eqhelekileyo 220 V AC, kwaye imveliso oqhubekayo ombane isipha - 3, 5, 12, kunye zombini polarities. Ukuba umcebisi evenkileni computing ukubuza umbuzo "Indlela ukhethe unikezelo lwamandla?" Yena, ke, uya kucebisa ukuba simse, kodwa wongezelela ukuba unikezelo kufuneka itshintshwe rhoqo kwiminyaka 1-2. Oku sokwandiswa ebalulekileyo ukuba akakho umntu hlobo, nangento engento. components lwangaphakathi kokusebenzisa umbane phezu ziyayeka ixesha ukuthobela iimpawu lowu (umzekelo, capacitors ezomileyo), ngoko ke kufuneka ukuba itshintshwe.

Ngoko ke, ukukhetha indlela unikezelo amandla? Uphawu lokuqala ibloko elungileyo ngqo - ubunzima bayo. Ikhala funny, kodwa yinyaniso. Ukutshintshela Power Supply - imveliso kunokuba entsokothileyo efuna umzobo Landela ngenyameko ngexesha ibandla. Ukuba sifumanisa ukuba iyunithi cheap Chinese, i ibhodi wesekethe eziprintiweyo ziya kusimangalise yobubanzi balo; phezu izinto ndawo ezimakishiweyo soldered zemoto, kwaye radiator ayikwazi kubizwa ngokuba omkhulu. Ngoko ke, xa ukhetha bengenazintloni ukuqikelela ubunzima block ngesandla.

Isiphakamiso yesibini yaziwa ukuba wonke umntu wakha wafunda kancinane, ukukhetha indlela ugesi. Ukanti phinda: kangangoko kunokwenzeka iyavakala ukuqokelela imali omncinane 'extra "kwaye bathenge imveliso neenkampani ezaziwayo-kakuhle - GlacialPower, Zalman, FSP, njl Le yunithi iza kubonelela ukusebenza oluthembekileyo computer njenge parameters zayo ngaphezulu okanye ezihambisana kangako kuyimfuneko .. Nanku umzekelo wobomi: kukho umbane ezimbini - watt Codegen 250 watts GlacialPower 450. Thina thelekisa data yokundwendwela ... yaye baqonde ukuba wonke umntu izibalo zabo. Isambuku umthamo sibhengezwe Codegen ne-imigca 3 no-5 lilingana parameter efanayo GlacialPower! Esi sigqibo izicacele - uthenga iiyunithi cheap Chinese kangangoko kunokwenzeka, kodwa reserve ngamandla kabini kwaye uzisebenzise akukho ngaphezu konyaka. Ukongeza, iimveliso ezinophawu inkxaso "Okukhona" ezahlukeneyo ezifana ulawulo fan ekrelekrele, nto leyo ethetha cwaka ngaphantsi ezixabisekileyo ngexesha lokusebenza.

Kwiinkqubo mihla, umthwalo eziphambili iwela kumgca-5 kunye 3.3V, ngoko kuyimfuneko ukuba ukhethe icandelo le yangoku iphezulu imigca (kokukhona, ngcono). Le uphawu kunye data yokundwendwela, ezi nqobo ngaso. Ukuba amandla ezi imigca lingaphantsi kwe kumqhubekekisi, ngoko ufuna model kakuhle.

Phambi kokuya evenkileni Kucetyiswa ukubala icandelo supply amandla. Kuba oku kukho iinkqubo ezikhethekileyo okanye websites. Kufuneka ukhankanye uhlobo iprosesa, ikhadi imizobo, inkumbulo, njalo njalo. Ngelo xesha khumbula ukuba ixabiso efunyenweyo iya kuba kubonisa, kunye nemodeli kufuneka zikhethwe ngokuba "ixabiso ebalwe ngayo + 20%."

Ukushwankathela:

- ibala amandla efunekayo;

- khetha i unikezelo lwamandla corporate enzima;

- uqinisekise ukuba amandla + 3.3V kunye + 5V kwanele.

Ukongezelela, unako ukuhlawula ingqalelo isixa izihlanganisi lwamandla: maxa wambi izihlanganisi ngokuba wada wabiliswa uphela nzima drives ayikho ngokwaneleyo kwaye kufuneka isetyenziswe kunye Molex iadaptha, nto leyo elula kakhulu.
