Into yokuqala okudingeka uyazi ubukhulu obuqondile bekesi lakho kanye nefomethi yokunikezwa kwamandla eliyisekelayo: i-ATX, i-SFX, i-TFX, njll. Ama-PC amaningi emidlalo asebenzisa amakesi e-ATX anezinsiza zamandla ze-ATX, kodwa izinhlelo ezincane zizodinga i-SFX noma izici ezincane zefomu.
Okulandelayo, udinga ukubala amandla ikhompyutha ewadingayo ngempela . Kwi-PC eyisisekelo (izinhlelo zokusebenza zehhovisi, ukuphequlula, i-multimedia), i-300-450W yanele kalula, kodwa uma sikhuluma nge-PC yokudlala noma indawo yokusebenza edinga ihluzo eziningi, izinto ziyashintsha, futhi i-600-750W iqala ukuba nomqondo omkhulu.
Okungcono kakhulu, kufanele uhlole izingxenye ezithile (iprosesa, ikhadi lehluzo, inani lama-hard drive, njll.) bese usebenzisa i-power calculator noma izincomo zomkhiqizi we-GPU ukuze uthole amandla angempela adingekayo. Lokhu kuqinisekisa ukuthi ukhetha ugesi ongu-750W one-margin efanele futhi ugweme ukuchitha imali.
Okokugcina, kufanelekile ukuhlola ukuthi ugesi unezixhumi ze-PCIe ezanele zamakhadi wehluzo ohlela ukuwasebenzisa, nokuthi amakhebula anobude obufanele bekesi lakho. Akuzona zonke izinsiza zamandla ezingu-750W ezenzelwe uhlobo olufanayo lokucushwa.
Ugesi okhethwe kahle ongu-750W, osebenza kahle kakhulu ongu-80 PLUS, ukuvikelwa okuphelele, ukufakwa kwezintambo okwanele kanye nokupholisa okuthule, kuba yisisekelo lapho yonke i-PC yakho isekelwe khona , okuvumela ihadiwe ukuthi isebenze ngamandla ayo aphezulu ngokuqina, ukuphepha kanye nendawo yokwandisa esikhathini esizayo.
