Ukuqonda izilinganiso ze-PC PSU Wattage ukuqinisekisa ukuthi unamandla anele
Ukuthengwa kwamandla amaningi emakethe yekhompuyutha yekhompuyutha ephathekayo kukhangiswa kuphela kwi-wattage yayo. Ngeshwa, lokhu kuyimbono elula yenkinga eyinkimbinkimbi kakhulu. Ukunikezwa kwamandla kukhona ukuguqula umthamo ophezulu ukusuka egumbini lokudongela ukuya emithanjeni engezansi edingekayo ukuze isebenzise izikhamera zekhompyutha. Uma lokhu kungenziwanga kahle, izimpawu zamandla ezingavamile ezithunyelwa ezingxenyeni zingabangela umonakalo nokungaqiniseki kwesistimu. Ngenxa yalokhu, kubalulekile ukuqinisekisa ukuthi uthenga ukunikezwa kwamandla okuhlangabezana nezidingo zekhompyutha yakho.
I-Peak vs. Okuphezulu kokuphuma kwamanzi
Lena yinto yokuqala ye-gotcha enkulu uma kuziwa ekubukeni kokunikezwa kwamandla kagesi. Isikali sokukhipha okuphezulu kunamandla angaphezu kwamandla angakwazi ukuwahlinzeka kodwa lokhu yisikhathi esifushane kakhulu. Izinyathelo azikwazi ukuqhubeka zihlinzeka ngamandla kuleli zinga futhi uma uzama ukwenza kanjalo zizolimaza. Ufuna ukuthola ukulinganisa okuqhubekayo kokuthambisa kwamandla kagesi. Leli lizinga eliphakeme kakhulu ukuthi i-unit ingahlinzeka ngokuqinile kwizingxenye. Ngisho nalokhu, ufuna ukuqinisekisa ukuthi ukulinganisa okuphezulu kwamanzi kuphakeme kunalokho ohlose ukukusebenzisa.
Enye into okufanele uyiqaphele ngokukhipha amanzi kuhlobene nokuthi ibalwa kanjani. Kunezinsika ezintathu zokuqala zamandla ngaphakathi kwamandla: + 3.3V, + 5V no + 12V. Ngayinye yalezi zinto zinikeza amandla ezinxenyeni ezihlukahlukene zesistimu yekhompyutha. Kuyinto ehlanganisiwe yamandla okukhipha okuvela kuyo yonke le migqa eyenza ukukhishwa kwamandla okuphelele kokunikezwa kwamandla. Ifomula elisetshenziselwa ukwenza lokhu yile:
- I-Wattage = I-Voltage * Amperage
Ngakho-ke, uma ubheka ilebula lokunikezwa kwamandla futhi kubonisa ukuthi umzila we-12V + unikeza amandla angu-18A, isitimela samandla anganika amandla angaphezu kuka-216W. Lokhu kungaba yingxenye encane kuphela ethi 450W amandla anikezwe. Ukukhishwa okukhulu kwemikhumbi ye + 5V no + 3.3V kuyobe kubalwa futhi kwengezwe esilinganisweni esiphezulu sokulinganisa.
& # 43; Isiteshi se-12V
Isitimela esibaluleke kunawo wonke esiteshini samandla yisitimela + esingu-12V. Lesi sitimela sezintambo sinikeza amandla ezingxenyeni ezifuna kakhulu kunazo zonke, kufaka phakathi iprosesa, imoto, abalandeli bokupholisa kanye namakhadi ehluzo. Zonke lezi zinto zidweba okuningi zamanje futhi ngenxa yalokho ufuna ukuqiniseka ukuthi uthenga ithuluzi elinika amandla okwanele esitimeleni se-12V.
Ngezimfuno ezikhulayo emigqeni engu-12V, izimpahla eziningi zamandla amasha zinamapayipi amaningi angu-12V azobalwa njenge-+ 12V1, + 12V2 no-12V3 kuye ngokuthi inezinsika ezimbili noma ezintathu. Uma ubala amps for line + 12V, kubalulekile ukubheka amps esiphelele ukukhiqiza kuzo zonke 12V rails. Izikhathi eziningi kungenzeka kube nombhalo waphansi wokuthi ukuhlanganisa u-wattage esiphezulu kuyoba ngaphansi kokulinganisa okuphelele kwemilayezo. Vele uphendule ifomu elingenhla ukuze uthole amps esiphezulu okuhlanganisiwe.
- Amperage = Amanzi / Amandla
Ngolwazi mayelana nemilayezo ye-12V, umuntu angayisebenzisa ngokumelene nokusetshenziswa kwamandla jikelele ngokusekelwe ohlelweni lwesistimu. Nazi izincomo zokulinganisa okungenani okuhlanganisiwe kwe-12V (kanye nesilinganiso sabo se-PSU sokuthambisa amanzi) ngezinhlelo ezahlukene zekhompyutha:
- I-Form Factor encane - 15A (250W)
- I-Mini-Tower - 25A (300-350W)
- I-Mid-Tower - 35A (400-500W)
- I-Full Tower - 40A (600-650W)
- Ikhadi levidiyo elibili (SLI) - 50A (750W +)
Khumbula ukuthi lezi zincoma kuphela. Uma unamakhemikhali athile alambile, hlola izidingo zokunikezwa kwamandla nomkhiqizi. Amakhadi amaningi ehlukumezayo ekugcineni angadonsela eduze kwe-200W ngaphansi komthwalo ogcwele. Ukugijima kwamakhadi amabili kungadinga kalula ukunikezwa kwamandla okungagcina okungenani okungu 750W noma ngaphezulu kokukhipha amandla okuphelele.
Ingabe Ikhompyutha Yami Ingayenza Lokhu?
Ngivame ukuthola imibuzo kubantu abafuna ukuthuthukisa ikhadi labo elihluziwe kwi-computer yabo yesistimu yekhompuyutha. Amakhadi amaningi ehluzo ephezulu aphezulu anezidingo ezicacile zamandla ukuze asebenze kahle. Ngokujabulisayo lokhu kuye kwathuthukiswa nabakhiqizi manje bebeka olunye ulwazi. Iningi lizobe lisho uhlu lwamanzi oluthunyiwe olunikezwayo kuphela kodwa okusemandleni kakhulu lapho behlonza inombolo encane ye-amps edingekayo emgqeni we-12V. Ngaphambilini azizange zishicilele noma yiziphi izimfuneko zokunikezela amandla.
Manje, ngokwamakhompiyutha amaningi edeskithophu, izinkampani ngokuvamile azihloni izilinganiso zokunikezwa kwamandla we-PC ngokucaciswa kwazo. Ngokuvamile umsebenzisi kuzodingeka avule leli cala futhi afune ilebula lokunikezwa kwamandla ukuze anqume ukuthi yini ngempela uhlelo olungase lisekele. Ngeshwa, ama-PC amaningi edeskithophu azofika ngemithombo yamandla ephansi njengamanyathelo okugcina izindleko. I-PC ejwayelekile yedeskithophu engazange ifike ngekhadi lehluzo elizinikezele ngokuvamile liyoba phakathi kwe-300 kuya ku-350W iyunithi enezinga elilinganiselwa ku-15 kuya ku-22A. Lokhu kuzoba kuhle kwamakhadi wegrafu esabelomali, kodwa amakhadi amaningi ehluzo zesabelomali ayenyuka ezimfuno zabo zamandla lapho bengasebenzi khona.
Iziphetho
Khumbula ukuthi konke esikukhulume ngakho kuhilela umkhawulo omkhulu wemishini yamakhompiyutha. Mhlawumbe u-99% wesikhathi lapho ikhompyutha isetshenziselwa, ayisetshenzisiwe ekufinyeleleni kwayo okuphezulu futhi ngenxa yalokho izothatha amandla amancane kunama-maximums. Into ebalulekile ukuthi amandla omshini wekhompiyutha adinga ukuba nekhanda elanele lalezo zikhathi ukuthi uhlelo lukhokhiswa kakhulu. Izibonelo zezikhathi ezinjalo zidlala imidlalo ye-3D enamandla kakhulu noma yenza i-video transcoding. Lezi zinto zikhokhisa kakhulu izingxenye futhi zidinga amandla engeziwe.
Njengoba kunjalo, ngifaka imitha yokusebenzisa amandla phakathi kokunikezwa kwamandla kanye nendawo yokudonga kwikhompyutha yami njengesivivinyo. Ngesikhathi sokusebenzisa i-computing, uhlelo lwami lwaludonsela amandla angaphezu kwama-240W. Lokhu kungaphansi kwesilinganiso sokunikezwa kwamandla wami. Kodwa-ke, uma ngidlala umdlalo we-3D ngamahora amaningana, ukusetshenziswa kwamandla kuphakama phezulu ku-400W wamandla angqikithi. Ingabe lokhu kusho ukuthi ukunikezwa kwamandla angama-400W kunganele? Mhlawumbe hhayi njengoba nginani elikhulu lezinto ezithinta kakhulu isitimela se-12V kangangokuthi i-400W ingaba nezinkinga zamandla okuvutha okwakungabangela ukungahleleki kwesistimu.
