Unitungiyar samar da wutan lantarki (PSU) ita ce na'urar don sauya ma voltageauran lantarki (220 volts) zuwa ƙayyadaddun ƙimar. Da farko, zamuyi la'akari da waɗanne ma'auni zaku iya zaɓar samar da wutar lantarki don kwamfutarka, sannan kuma zamuyi la'akari da wasu maki a cikin ƙarin bayanai.
Babban kuma zaɓi na zaɓaɓɓen zaɓi (PS) shine matsakaicin ikon da ake buƙata ta na'urorin kwamfuta, wanda aka auna a cikin raka'o'in ikon da ake kira Watt (W, W).
Kimanin shekaru 10-15 da suka gabata, don aiki na yau da kullun na kwamfuta, ba a buƙaci sama da watts 200 ba, amma a cikin lokacinmu wannan ƙimar ya karu, saboda bayyanar sabbin abubuwan haɗin da ke cinye dumbin makamashi.
Misali, katin alamomin SAPPHIRE HD 6990 na iya cinye watts 450! I.e. Don zaɓar wutar lantarki, kuna buƙatar yanke shawara akan abubuwan haɗin da gano menene ƙarfin su.
Bari muyi la’akari da yadda za a zabi PSU (ATX) da ya dace:
- Mai sarrafawa - 130 W

- HDD -40 W 2pcs
- Katin bidiyo -300 W
- CD-ROM, CD-RW, DVD -2 0W
- Masu sanyaya - 2 W 5pcs
Don haka, ga jerin tare da kayan haɗi da kuma karfin da suke ci, don lissafin ƙarfin PSU, kuna buƙatar ƙara ikon duk abubuwan haɗin, da + 20% don hannun jari, i.e. 130 + 40 + (20) + (80) + 300 + 20 + (10) = 600. Don haka, jimlar ƙarfin abubuwan da aka gyara sune 600 watts + 20% (120 W) = 720 watts i.e. don wannan komputa, ana bada shawarar wutan lantarki aƙalla 720 W.
Mun tsara ikon, yanzu bari muyi kokarin gano ingancin: yana da iko, baya nufin inganci. A yau a kasuwa akwai wadatattun kayan wutar lantarki daga masu araha mara nauyi zuwa sanannun kayayyaki. Hakanan za'a iya samun ingantaccen samar da wutar lantarki tsakanin masu arha: gaskiyar ita ce, ba dukkanin kamfanoni ke yin PSUs da kansu ba, kamar yadda aka saba a kasar Sin, yana da sauƙin ɗauka da sanya wasu mashahuran masana'antun bisa tsarin da aka tsara, kuma wasu suna yin hakan sosai, don haka ingantaccen ingancin zai iya zama haɗuwa ko'ina, amma yadda za a gano ba tare da buɗe ƙofa ba tambaya ce mai wuya.
Koyaya, zaku iya ba da shawara game da zabar wadatar wutar lantarki ta ATX: PSU mai inganci ba zata iya yin ƙasa da 1 kg ba.
