Kodi mphamvu ndi chiyani?
Pulogalamu yamagetsi (PSU) ndi chida chothandizira kutembenuza magetsi (220 volt) kuzinthu zoyenedwa. Poyambira, tidzakambirana zoyenera kusankha kusankha makina, ndikuyang'ana mfundo zina mwatsatanetsatane.
Chotsatira chachikulu ndi chachikulu (PSU) ndi mphamvu yowonjezera yomwe amayenera ndi zipangizo zamakono, zomwe zimayesedwa mu magulu a mphamvu otchedwa Watts (W, W).
Zaka 10-15 zapitazo kuti kachitidwe ka kompyuta kawirikawiri sikatenge ma watt 200, koma masiku ano kufunika kwake kwawonjezeka, chifukwa cha kutuluka kwa zigawo zatsopano zomwe zimadya mphamvu zambiri.
Mwachitsanzo, khadi imodzi ya kanema ya SAPPHIRE HD 6990 ikhoza kudya mpaka 450 W! I Kusankha unit of power supply, muyenera kusankha pa zigawo zikuluzikulu ndi kupeza chomwe mphamvu yawo ndi.
Tiyeni tiwone chitsanzo cha momwe mungasankhire BP yoyenera (ATX):
- Pulosesa - 130 W
- -40 W boardboard
- Kumbukirani -10 W 2pcs
- HDD -40 W 2pcs
- Khadi la Video -300 W
- CD-ROM, CD-RW, DVD -2 0W
- Zowonjezera - 2 W 5pcs
Kotero, muli ndi mndandanda ndi zida zomwe zimagwiritsidwa ntchito ndi mphamvu zawo, kuti muwerenge mphamvu ya magetsi, muyenera kuwonjezera mphamvu ya zigawo zonse, ndi 20% pa katundu, mwachitsanzo. 130 + 40 + (20) + (80) + 300 + 20 + (10) = 600. Choncho, mphamvu yonse ya zigawozo ndi 600W + 20% (120W) = 720 ma watita. Kwa makompyuta awa, chipangizo cha magetsi chokhala ndi mphamvu zokwana 720 W chilimbikitsidwa.
Tinazindikira mphamvu, tsopano tiyesa kuyesa khalidwe: pambuyo pake, mphamvu sizitanthauza khalidwe. Masiku ano pamsika pali magetsi ochuluka ochokera kumsika wotchipa opanda dzina mpaka odziwika bwino. Mphamvu zabwino zingapezekenso pakati pa ndalama zotsika mtengo: mfundo ndi yakuti sikuti makampani onse amapanga mphamvu zawo, monga momwe zimakhalira ku China, n'zosavuta kutenga ndi kuzipanga mogwirizana ndi dongosolo lokonzekera la wopanga wina wapamwamba, ndipo ena amachita bwino kwambiri, khalidwe lokongola likhoza kukhala kukakumana kulikonse, koma momwe mungapezere popanda kutsegula bokosi ndilo funso lovuta.
Komabe mukhoza kupereka uphungu pa kusankha mphamvu ya ATX: mphamvu yamagetsi siingakhoze kulemera kuposa 1 kg. Samalani kuyika kwa mawaya (monga pa chithunzi) ngati 18 awg yalembedwa apo, ndiye izi ndizochitika ngati 16 awg, ndiye zabwino kwambiri, ndipo ngati 20 awg, ndiye kuti ndizo zapansi kwambiri, mungathe kunena zolakwika.
Inde, ndibwino kuti musayesere tsoka ndikusankha BP ya khama lolemekezeka, pali chitsimikizo ndi chizindikiro. M'munsimu muli mndandanda wa magetsi ozindikiridwa:
- Zalman
- Thermaltake
- Corsair
- Kutha
- FSP
- Mphamvu ya Delta
Palinso vuto lina - ndilo kukula kwa magetsi, zomwe zimadalira mawonekedwe a momwe zidzakhalire, komanso mphamvu ya mphamvuyo, makamaka mphamvu zonse ndi ATX muyezo (zomwe zikuwonetsedwa pa chithunzi chili m'munsimu), koma pali mphamvu zina zomwe siziri za miyezo ina.
