Ukuhlinzekwa kwamandla (BP) i-Voltage Voltage Conversition ye-Network (220 VOLT) kumanani acacisiwe. Okokuqala, sizobheka ukuthi yiziphi izindlela ongazikhetha ukuze uthole amandla ekhompyutheni, bese ubheka amaphuzu athile ngokuningiliziwe.
Isikhombisi esiphambili nesiyinhloko sokukhetha (BP) yingxenye ephezulu yedivayisi yekhompyutha, elikalwa emayunithi wokulinganisa amandla abizwa ngokuthi i-watt (W, W).
Cishe eminyakeni eyi-10-15 edlule, kwadingeka ama-watts angaphezu kuka-200 ukuze asebenze ngokujwayelekile kwekhompyutha evamile, kepha esikhathini sethu kwanda, ngenxa yokuvela kwezinto ezintsha ezidla inani elikhulu.
Isibonelo, ikhadi elilodwa le-Sapphire HD 6990 levidiyo lingadla lifinyelela ku-450 w! Lezo. Ngokukhethwa kwe-BP, udinga ukunquma ngezakhi futhi uthole ukuthi yini ukusetshenziswa kwamandla kwawo.
Ake sibheke isibonelo, ukuthi ungayikhetha kanjani i-BP efanele (ATX):
- Processor - 130 w
- Umama -40 W
- Imemori -10 w 2pcs
- HDD -40 W 2PC
- Ikhadi levidiyo -300 W.
- CD-ROM, CD-RW, DVD -2 0W
- I-Cooleers - 2 w 5pcs
Ngakho-ke, phambi kwakho Uhlu ngezakhi namandla adliwayo, kuyadingeka ukwakha amandla ezinto zonke ukubala amandla we-BP, kanye + no-20% wesitoko, i.e. 130 + 40 + (20) + (80) + 300 + 20 + (10) = 600. Ngakho-ke, amandla aphelele engxenye ngu-600vatt + 20% (120 W) = 720 Watts I.e. Kule khompyutha, kunconywa ukuthi amandla we-BP awaphansi kuka-720 W.
Ngamandla, sicabange, manje sizozama ukubhekana nekhwalithi: Ngemuva kwakho konke, akusho ikhwalithi. Namuhla emakethe kunenombolo enkulu yamandla atholakalayo kusuka kuma-eshibhile angabingelwa kahle kumikhiqizo eyaziwa kakhulu. Ukunikezwa kwamandla okuhle nakho kungahle kube chemod kusuka ekutheni awekho amafemu enza i-BP ngokwawo uqobo, ngoba ngokwesiko ukukwenza kube lula ukuyithatha nokwenza kahle uhlelo olwenziweyo lomkhiqizi othile ovelele, futhi abanye benza kahle kakhulu, kanjalo Imfanelo yekhwalithi ingahlangana yonke indawo, kepha indlela yokuthola ngaphandle kokuvula ibhokisi sekuvele kungumbuzo onzima.
Futhi nokho unganikeza izeluleko ngokukhethwa kwe-ATX Power Supply: I-BP ephezulu ye-BP ayikwazi ukukala okungaphansi kwe-1 kg. Naka ukumaka ngocingo (njengasesithombeni) Uma kubhalwe i-18 AWG lapho, khona-ke lokhu kuyinto evamile uma kungu-16 awg, bese kuba yi-20 awg, khona-ke sekuyi-wire ephansi, wena angasho umshado.
Vele, kungcono ukuthi ungabi nakade ikusasa futhi ukhethe amafemu afakazelwe we-BP, kunesiqinisekiso kanye nomkhiqizo. Ngezansi uhlu lwezitembu ezaziwayo ze-Power Supplies:
- UZalman.
- Ishuartake
- I-Corsair.
- Hiper.
- I-FSP.
- Amandla we-Delta
Kukhona enye inqubomgomo - lokhu usayizi wokuhlinzekwa kwamandla, kuya ngesimo somzimba wecala lapho kuzokuma khona, futhi amandla e-BP uqobo, futhi wonke amandla akhona yi-ATX Standard (ekhonjiswe kwisibalo esingezansi ) Kepha kukhona amanye ama-bps okungewona amazinga athile.
