Ukuhanjiswa kwamandla (BP) sisixhobo sokuguqula kwe-voltage yenethiwekhi (i-220 volt) ukuya kwiinqobo ezichaziweyo. Okokuqala, siza kujonga ukuba yeyiphi imigaqo ongathanda ukuyikhetha amandla kwikhompyuter, emva koko uqwalasele amanqaku ngakumbi.
Eyona nto iphambili kunye nephambili (BP) yelona candelo liphezulu lesixhobo sekhompyuter, elilinganiswe kwicandelo lokulinganisa lwamandla elibizwa ngokuba litt (W).
Malunga ne-10-15 kwiminyaka eyadlulayo, kungabikho ngaphezulu kwe-200 watts, kodwa kwakufuneka ngaphezulu kokusebenza okuqhelekileyo kwekhompyuter, kodwa ixesha lethu lisanda, ngenxa yokuvela kwamacandelo amatsha asebenzisa amandla amakhulu.
Umzekelo, enye i-Sapfire HD 6990 ikhadi levidiyo inokutya ukuya kuthi ga kwi-450 w! Ezo. Ukukhethwa kwe-BP, kuya kufuneka uthathe isigqibo malunga nezinto kwaye ufumanise ukuba yintoni eselwayo amandla.
Makhe sijonge umzekelo, indlela yokukhetha i-BP elungileyo (i-ATX):
- Iprosesa - 130 w
- Ibhodi ye-Unimart -40 w
- Inkumbulo -10 w 2pcs
- I-HDD -40 w 2pc
- Ikhadi levidiyo -300 W.
- I-CD-ROM, CD-RW, DVD -2 0W
- Iicoelers - 2 w 5pcs
Ke, phambi kwakho uluhlu kunye nezinto kunye namandla achithwe ngabo, kufuneka ukuba benze amandla kuwo onke amacandelo okubala amandla e-BP, kunye neepesenti ezingama-20 kwisitokhwe, i.e. 130 + 40 + (20) (80) + 35 + 20 + (10) = 10) = 600. Ke, amandla ewonke-mva eyi-600vatt + 20% (120 w) = 020 watts i.e. Kule khompyuter, kucetyiswa ukuba amandla e-BP akaphantsi kwe-720 w.
Ngamandla, saphoswa, ngoku siza kuzama ukujongana nomgangatho: emva kwayo yonke loo nto, ayithethi ukuba incinci. Namhlanje kwimarike kukho inani elikhulu lezinto ezingabizi igama eliphantsi kwiimpawu ezaziwayo. Ukuhanjiswa kwamandla okuLungileyo kunokuba kukusikisha ngenxa yokuba kungabikho zonke iifemu zenza ukuba zizenze zibe lula ukuba zithathe lula ukuthatha kwaye zenze kakuhle, kwaye ezinye zenza kakuhle, kunjalo Ukufaneleka komgangatho kunokudibana naphi na, kodwa njani ngaphandle kokuvula ibhokisi sele umbuzo onzima.
Ukanti unganika ingcebiso ngokukhetha ubonelelo lwaMandla lwe-ATX: I-BP ephezulu ye-BP ayinakuba nobunzima obungaphantsi kwe-1 kg. Nikela ingqalelo kwi-Wire Mark (njengamfanekiso) Ukuba i-18 OWG ibhaliwe apho, ke le yinto ye-16 AWG, ke i-OWG ye-AWG, wena Nokuba ungathanda ukutshata.
Ewe kunjalo, kungcono ukungafumani ikamva kwaye ukhethe iifemu eziqinisekisiweyo ze-BP, kukho isiqinisekiso kunye nophawu. Apha ngezantsi luluhlu lwezitampu ezazichongiweyo zezinto ezibonakalayo zombane:
- UZalman.
- I-thermaltkeke
- I-corsair.
- Hiper.
- I-FSP.
- I-Delta amandla
Kukho enye ikhrayitheriya-olu lubukhulu becala lokuhambisa amandla, nto leyo kuxhomekeke kwimeko yomzimba wetyala apho iya kuma khona, kwaye uninzi lwe-BP ngokwalo ngumgangatho ongezantsi (oboniswe kumzobo ongezantsi ) Kodwa kukho ezinye ii-BPS ezingeyiyo kwimigangatho ethile.
