Kodi magetsi ndi chiyani?
Chipangizo chamagetsi (PSU) ndi chida chosinthira mains volts (ma volts makumi awiri ndi ziwiri) kuti akhale amtundu wofunikira. Poyamba, tikambirana magawo omwe mungasankhe magetsi pakompyuta yanu, kenako tikambirana mfundo zina mwatsatanetsatane.
Choyimira chachikulu komanso chosankha chachikulu (PS) ndi mphamvu yayikulu yofunika ndi makompyuta, omwe amayeza mu magulu amagetsi otchedwa Watt (W, W).
Pafupifupi zaka 10-15 zapitazo, pogwira ntchito bwino kompyuta yapakatikati, osaposa 200 watts, koma m'nthawi yathuyi mtengowu ukuwonjezeka, chifukwa cha mawonekedwe atsopano omwe amatenga mphamvu zambiri.
Mwachitsanzo, khadi imodzi yakujambula ya SAPPHIRE HD 6990 imatha kudya mpaka ma 450 watts! Ine.e. Kuti musankhe magetsi, muyenera kusankha pazinthuzo ndikupeza momwe magetsi amagwiritsira ntchito.
Tiyeni tiwone chitsanzo cha momwe mungasankhire PSU yoyenera (ATX):
- Pulosesa - 130 W
- -40W mama
- Memory -10 W 2pcs
- HDD -40 W 2pcs
- Khadi ya kanema-300 W
- CD-ROM, CD-RW, DVD 2 0W
- Ozizira - 2 W 5pcs
Chifukwa chake, nayi mndandanda wokhala ndi zigawo ndi mphamvu zomwe zimagwiritsidwa ntchito ndi iwo, kuti muwerenge mphamvu za PSU, muyenera kuwonjezera mphamvu pazigawo zonse, ndipo + 20% ya masheya, i.e. 130 + 40 + (20) + (80) + 300 + 20 + (10) = 600. Chifukwa chake, mphamvu yathunthu yazigawo ndi 600 watts + 20% (120 W) = 720 watts i.e. pa kompyuta iyi, magetsi osachepera 720 W akulimbikitsidwa.
Tapeza mphamvu, tsopano tiyeni tiyesetse kudziwa kuti zili ndi mphamvu yanji: sizothandiza. Masiku ano pamsika pali kuchuluka kwamphamvu zamagetsi kuchokera pamtengo wotsika mtengo kupita kuzinthu zodziwika bwino. Magetsi abwino amapezekanso pakati pa otsika mtengo: chowonadi ndichakuti si makampani onse omwe amapanga PSU okha, monga zimakhalira ku China, ndizosavuta kutenga ndikupanga ena otchuka molingana ndi mapulani omwe adakonzedwa kale, ndipo ena amachita bwino kwambiri, kotero kuti mtundu wabwino ungakhale wabwino mumakumana paliponse, koma momwe mungadziwire popanda kutsegula bokosi ndi funso lovuta.
Komabe, mutha kupereka upangiri posankha magetsi a ATX: PSU yapamwamba kwambiri sangathe kulemera kilo imodzi. Samalani ma waya omwe ali ndi chizindikiro (monga pachithunzichi) ngati 18 awg yalembedwa pamenepo, ndiye kuti izi ndi zofunikira ngati 16 awg, ndiye izi ndi zabwino kwambiri, koma ngati 20 awg, ndiye kuti mawaya ali otsika kale, mutha kunena kuti ukwati.
Zachidziwikire, ndibwino kuti musayesere zamtsogolo ndikusankha BP ya kampani yotsimikiziridwa, pali chitsimikizo komanso mtundu. Pansipa pali mndandanda wazinthu zamagetsi zomwe zimadziwika:
- Zalman
- Thermaltake
- Corsair
- M'chiuno
- Fsp
- Mphamvu ya Delta
Palinso chitsimikizo china - kukula kwa magetsi, komwe kumatengera momwe mlanduwo udayikidwira, ndi mphamvu ya PSU yokha, magetsi onse ndi a ASX muyezo (omwe awonetsedwa pamwambowu), koma pali ma PSU ena omwe sakukhudzapo mfundo zina.
