Indlela yokukhetha ukunikezwa kwamandla futhi ungalokothi ubambe ama-elbows akho kamuva

Iningi (uma kungenjalo) lamagumbi okuthengiswa kwamandla wekhompiyutha athengiswayo ahlangene eChina. Yiqiniso, isitatimende esithi "I-China i-China ihlukile" ayikhanseliwe, kodwa ikhwalithi yezinqwaba zala madivaysi, ukuyibeka ngomoya ophansi, usezingeni eliphansi. Leli qiniso alifihliwe yimuphi umuntu, ngokuvamile umbuzo uphakanyisiwe, ukuthi ungakhetha kanjani ukunikezwa kwamandla. Ngaphezu kwalokho, ngisho nabakhiqizi abaziwayo bavame ukukhombisa amaphesenti overestimated for 20 amanani of currents ezilinganiselwe. Empeleni, bangaqondakala, ngoba emncintiswaneni wamakethe onzima wokusinda zonke izindlela zilungile, kahle, umsebenzisi ... kufanele afunde ngokucophelela idatha yepasipoti yezinto zokusebenza futhi aqonde ukuthi angakhetha kanjani ukunikezwa kwamandla kwikhompyutha. Sizokukhuluma ngalokhu namuhla.

I-unit supply supply itholakala ekhompyutheni yekhompuyutha futhi inikeza zonke izingxenye kagesi. Ngokuvamile, umsebenzi obelwe wona ulula futhi usuxazululiwe ngempumelelo ekubunjeni kagesi: izinga elijwayelekile 220 V AC lisetshenzisiwe ekufakweni, futhi inqwaba yezintambo eziqhubekayo - 3, 5, 12 V, nazo zonke zomzimba ezivela emkhathini. Uma umxhumanisi esitolo sekhompiyutha ebuza umbuzo othi "Ungakhetha kanjani ukunikezwa kwamandla?", Yebo, uzokwazisa isisombululo esiphezulu, kodwa uyanezela ukuthi kunconywa ukuthi ushintshe amabhlogo njalo eminyakeni engu-1-2. Lokhu kuhlanganisa okubalulekile, okungavamile ukulandelwa, kodwa ngeze. Izakhi zangaphakathi zokunikezwa kwamandla axhumeneyo azihambisani nezici ezimenyezelwe ngekhathi (isibonelo, ama-capacitors ayomile), ngakho-ke idinga ukuguqulwa.

Ngakho, ungakhetha kanjani ukunikezwa kwamandla? Isibonakaliso sokuqala esingaqondile sebhokisi elihle yisisindo salo. Kuzwakala funny, kodwa kuyiqiniso ngempela. I-unit switching power supply iyisimikhiqizo esiyinkimbinkimbi, esidinga ukulandelwa ngokucophelela kwesifunda ngesikhathi somhlangano. Uma uvula ibhuloho elishibhile laseChina, i- PCB izomangaza ngokungazi lutho kwayo: esikhundleni sezinto eziphawulekayo ezithengiswa nge-jumper, futhi i-radiator ayikwazi ukubizwa ngokuthi i-massive. Ngakho-ke, lapho ukhetha ukungabi namahloni ukuhlola isisindo se-block.

Ukuncoma kwesibili kwaziwa kuwo wonke umuntu ofunde okungenani ukuthi angakhetha kanjani ukunikezwa kwamandla. Noma kunjalo, uma kunokwenzeka, kunengqondo ukuqoqa imali encane futhi uthenge umkhiqizo wezinkampani eziyaziwa kahle - GlacialPower, Zalman, FSP, njll. Leyo unit izoqinisekisa ukusebenza okuthembekile kwikhompyutha, ngoba imingcele yayo ingaphezulu noma eyanele. Ake sinikeze isibonelo esivela ekuphileni: kunezimboni ezimbili zokunikezela amandla - iGlacialPower enegunya lika-450 W ne-Codegen elinama-250 W. Qhathanisa idatha yepasipoti futhi ... siyaqonda ukuthi wonke umuntu unezibalo zakhe. I-Codegen yamandla ekhokhelwe yonke imali ku-line engu-3 no-5 V ilingana nepharamitha efanayo ye-GlacialPower! Isiphetho sisobala - izitshalo ezishibhile zaseChina zingathengwa, kodwa zigcinwe kabili ngamandla futhi zingasebenzisi okungaphezu konyaka. Ukwengeza, imikhiqizo ekhonjiswe ngokusekelwa isekela "izinto ezihamba phambili" ezihlukile, isibonelo, ukulawula ukushayela okuhlakaniphile, okusho ukuthula okubaluleke kakhulu emsebenzini.

Ezikhathini zanamuhla, umthwalo oyinhloko uwela emgqeni +5 no +3.3 V, ngakho-ke i-unit kufanele ikhethwe ngokususelwa kumanje owedlule wale migqa (ngaphezulu, okungcono). Esikhathini esitokisini nedatha yepasipoti, lezi zindinganiso zinikezwa njalo. Uma amandla alala migqa engaphansi kweyeprosesa, sibheke imodeli ephumelelayo kakhulu.

Ngaphambi kokuya esitolo kunconywa ukubala amandla weyunithi yamandla. Kulokhu, kunezinhlelo ezikhethekile noma amawebhusayithi. Kubalulekile ukucacisa uhlobo lweprosesa, ikhadi le-video, imemori, njll. Khumbula ukuthi inani elitholakalayo lizobonisa, futhi imodeli kufanele ikhethwe ngokuthi "inani elibalwa + 20%".

Ake sibone:

- Bala amandla adingekayo;

- khetha ukuthengiswa kwamandla kagesi;

- siyaqiniseka ukuthi amandla ka-+3.3 no-+5 V anele.

Ngaphezu kwalokho, unganaka inani lamandla okuxhumana: ngezinye izikhathi izixhumi ze-drives ze-SATA azikhanele futhi kufanele usebenzise ama-adapter nge-Molex, okungeyona elula kakhulu.
