Kuyini ukunikezwa kwamandla futhi kuyini?
I-unit supply unit (PSU) iyisidingo sokuguqula amashini wamandla (220 volt) kumanani acacisiwe. Okokuqala, sizocubungula indlela yokukhetha amandla wekhompuyutha, bese sibheka amanye amaphuzu ngokuningiliziwe.
Umgomo oyinhloko nokukhetha oyinhloko (PSU) amandla amakhulu adingekayo ngamadivayisi wekhompuyutha, okulinganiselwe kumagumbi wamandla abizwa ngokuthi iWatts (W, W).
Eminyakeni engu-10-15 eyedlule ukusebenza okuvamile kwekhompiyutha ejwayelekile akuzange kuthathwe ama-Watts angaba ngu-200, kodwa nanamuhla leli nani liye landa, ngenxa yokuvela kwezingxenye ezintsha ezidla amandla amaningi.
Isibonelo, ikhadi elilodwa le-SAPPHIRE HD 6990 lingadla ku-450 W! Yebo Ukuze ukhethe unit unit supply, udinga ukunquma on izingxenye futhi uthole ukuthi amandla abo ukusetshenziswa.
Ake sibone isibonelo sendlela yokukhetha i-BP efanele (ATX):
- Iprosesa - 130 W
- -40 Wama-motherboard
- Imemori -10 W 2pcs
- I-HDD -40 W 2pcs
- Ikhadi levidiyo -300 W
- CD-ROM, CD-RW, i-DVD -2 0W
- Ama-cooler - 2 W 5pcs
Ngakho-ke, unalo uhlu olunezingxenye namandla adliwe yiwo, ukubala amandla weyunithi yokunikezela amandla, udinga ukwengeza amandla azo zonke izingxenye, no-20% esitokisini, njll. I-130 + 40 + (20) + (80) + 300 + 20 + (10) = 600. Ngakho-ke, amandla angqangi wezingxenye zingama-600W + 20% (120W) = 720 ama-watts i.e. Kule khomputha, insiza yokunikezela amandla enekhono lokungenani okungu-720 W inconywa.
Sithole amandla, manje sizozama ukuthola ikhwalithi: ngemuva kwakho konke, amandla asho imfanelo. Namuhla emakethe kunenani elikhulu lempahla yamandla kusuka ezishibhile ezingenazo izimpawu ezaziwa kakhulu. Ukutholakala kwamandla omuhle kungatholakala phakathi kwezinto ezishibhile: iqiniso lokuthi akuwona wonke amafemu enza amandla ayo, njengokwesiko e-China, kulula ukuwuthatha futhi ukwenze ngokwesiko esilungisiwe somkhiqizi othile ovelele, kanti abanye bakwenza kahle kakhulu, ikhwalithi ehloniphekile kungenzeka ukuhlangabezana yonke indawo, kodwa ukuthi ungathola kanjani ngaphandle kokuvula ibhokisi kakade umbuzo onzima.
Noma kunjalo unganika iseluleko ngokukhetha amandla we-ATX: ukunikezwa kwamandla okukhwalithi akukwazi ukukala okungaphansi kwe-1 kg. Qaphela ukubhala kwezintambo (njengokusesithombeni) uma ku-18 awg ebhaliwe lapho, khona-ke lokhu kuyinto evamile uma ku-16 awg, ngakho-ke kuhle kakhulu, futhi uma ngabe i-awg 20, bese isivele yekhwalithi ephansi kakhulu, ungasho ngisho nephutha.
Yiqiniso, kungcono ukuthi ungalingi isiphetho futhi ukhethe i-BP yenkampani ehloniphekile, kukhona kokubili isiqinisekiso kanye nomkhiqizo. Ngezansi uhlu lwamatshe aqinisekisiwe wempahla:
- Zalman
- Thermaltake
- Corsair
- I-Hiper
- FSP
- Amandla eDelta
Kunomunye umgomo - ubukhulu bokunikezwa kwamandla, okuxhomeke efomini yefomu yocala lapho lizohlala khona, namandla okunikezwa kwamandla ngokwawo, ngokuyinhloko konke ukunikezwa kwamandla kuyi-standard ye-ATX (ekhonjiswe kumfanekiso ngezansi), kodwa kuneminye imishini engeyona eyakhe izindinganiso ezithile.
