Iiyunithi Amandla for iikhompyutha: top abavelisi, iimpawu, imithetho yokukhetha

Ukuthenga ikhompyutha abantu kude zisuswe ubugcisa, ubukhulu becala kuphela ingqiqo ka "ikhadi", "iprosesa" yaye "memory". Noko ke, phezu unikezelo amandla ngenxa yesizathu esithile, khumbula kule ethubeni yokugqibela. Kwaye xa kufika, kwiimeko ezininzi, bekuya-kuba abaqokeleli bezama ukusindisa kangangoko kunokwenzeka kuwo, imali namanye amacandelo PC.

"Yinto nje ibhokisi, luphe into amandla. Nangona abanye uya kuhla, okona kubaluleke kakhulu, makube ezinamandla kwaye sitshiphu ngakumbi! "- indlela yinto eqhelekileyo kunye, ngeliphandle, yintlekele. Ngelishwa, kuyacaca kuphela xa ababehlangene computer. Lucky ukuba nokuba iqala. Ngokuphindiwe lucky, ukuba umsebenzi uzinzile yaye akukho ezivelayo. Kwaye kufuneka ukuba ulonwabo, ukuba deshovenky umbane ekugqibeleni ayiyi kuphela kwiinyanga ezimbalwa ezizayo, "urhuqe 'ukuba ezinye izakhi ithile inika amandla.

Kodwa ngokwenene oku siqinisekiso kuphela izinto ezikumgangatho ophezulu amandla we computers, abavelisi abaphezulu ngokuzithemba waqhubeka kwizikhundla ezifanelekileyo. Ngoko ke, ukukhetha imveliso onobuchule, nto leyo eneneni uya kusebenza kuzo zonke idenariyo ixabiso layo, ihlala kuphela ukuba umthengi, leyo, Kakade ke, kufuneka bazazi iimpawu eziphambili umbane kunye ukuqonda yeyiphi abenzi ngokwenene athembeke.

Amandla xa iyonke

Le fowuni engundoqo sentlalo, umsebenzisi unomdla kwindawo yokuqala. Xa ukhetha amaninzi adla ezilahlekileyo ngokwemiqathango watts, nezinika onke amandla ikhompyutha. Ukunqongophala amandla nethala iindlela zokusebenza ezingazinzanga (nangaphaya kwayo start-up). Kwelinye icala, ngokungeyomfuneko umbane ubunakho kuya kubangela ngesibetho kakhulu nebhajethi, ukuba sele iphetshwe.

ukusetyenziswa kwamandla PC kwimeko nganye ukuba ibalwe ngamnye, ngokusekelwe iseti lokugqibela amacandelo. Musa ukulibala ukuba kulo mzekelo BP kufuneka ubuncinane unikezelo lwamandla encinane uluhlu 20-25% lombane amandla theoretical component. Kuba ezi zibalo le web kukho ezininzi zokubala ezizodwa. Eyona echanekileyo (kwaye ngoko ezithandwayo phakathi kwabantu) khetho kupholile Master Power Supply Calculator. Inika abasebenzisi nje ezimbini iintlobo zomsebenzi:

Ukulahleka okanye ukwanda yonikezelo ombane akayi kubangela PSU kwi imeko nandzu. Ukusuka apho, yona, akukho inshorensi iindlela ezilula enganeno.

Umsebenzisi ngamnye Kucetyiswa ngamandla ukukhangela nasiphi imodeli umdla BP kwiirivyu kunye mvavanyo, ezo zifumaneka simahla. Uyacetyiswa ukuba ukukhangela ulwazi ubuncinane 2-3 imithombo, kuthathelwa ingqalelo ncomo akhawunti kunye nomthengi, ukuba zikhona. Ekugqibeleni uya kuba yonke into yaye uya kwenza ukhetho olufanelekileyo - ukuze ukhethe unikezelo amandla imali okanye hayi.

ukusebenza

Injalo loo nto, xa reserve amandla ukwanele nkqubo kunye uvimba. Excellent, ukuba ombane kuyo yonke imigca akuthethi ingagqithi kwimiqathango yokwakha. Kodwa xa kufikwa ukwalathisa zokuhambisa umbane ukusuka isixhobo iikhithi, lembombo yonke inkqubo uba pinout yeyunithi umbane ikhompyutha (okanye iseti iintambo, nto leyo eza kubonelelwa kwiincindi PC eseleyo).

Ukusuka bahlukaniswa iintlobo ezimbini ezinkulu. Okokuqala - EATX 24pin, bekujongiwe unikezelo motherboard amandla. Okwesibini - 12V, ophetheyo iprosesa ukutya. Kuba motherboards yesiqhelo kufuneka kuphela 4pin-uguqulelo. Nangona kunjalo, kwiimeko ngenkxaso overclocking kwakhula amandla, apho sele kukho khetho 8pin (okanye 4 + 4pin).

Gqibezela kunye pinouts ezisisiseko intambo naliphi na unikezelo lwamandla ikhompyutha ibandakanya ezinye extra:

• PCI-E.
• Wada wabiliswa uphela.
• Fan izihlanganisi.
• Molex.

Inani labo inokwahluka ngokuxhomekeke kuhlobo oluthile PD. Qiniseka ukukhangela ukuba imveliso omabini ubude eyaneleyo kunye nenani kweentambo ezifunekayo ye computer eyenzelwe yona. Oku ngakumbi ishenxisa uphendlo ngokukhawuleza izandiso ezongezelelweyo kunye ezisebenza ngokubakho.

Elokugqiba, qiniseka ukuba banikele ingqalelo ubukho lonke ukhuselo iisekethe ezintandathu PD kwiimeko zongxamiseko:

• OCP (Over Protection yangoku) - Ukhuseleko ngokuchasene coil.
• OVP (Over Voltage Protection) - wokukhuselwa ombane aphezulu ubonelelo.
