Ndizovuta kulingalira kuti Nvidia adzakankhira ziwerengerozo kwambiri mum’badwo wotsatira wa ma GPU.

Mndandanda wa RTX 50 sunathe kupewa mikangano yokhudzana ndi mphamvu, komabe. Lamulo la Moore Lakufa posachedwa adawulula kuti Nvidia akukonzekera kugwiritsa ntchito cholumikizira chatsopano, chomwe chingakhale chachinayi kusintha kotereku pakatha zaka zitatu zokha. The YouTuber imatchula magwero osadziwika, ponena kuti Nvidia akusintha ku cholumikizira cha 16-pin, zonse zoperekedwa ku 12V magetsi. Komabe, magwero ena ambiri akuwonetsa kuti izi sizingatheke.

Hardware Busters adafikira kumagwero ake ndikutsimikizira kuti “palibe amene akudziwa cholumikizira chatsopano.” Nvidia amayenera kugwira ntchito ndi mitundu yayikulu ya PSU, makamaka pambuyo pazovuta ndi cholumikizira cha 12VHPWR. Ngati ma brand awa sakudziwa kalikonse za izi, Nvidia mwina sakusintha m’badwo uno.

M’malo mwake, Nvidia atha kuwirikiza kawiri pa chisankho chogwiritsa ntchito cholumikizira cha 12VHPWR. Malinga ndi TechRadarNvidia ikhoza kupanga chojambulira cha 12VHPWR kukhala chinthu chovomerezeka kwa GPU iliyonse kudutsa RTX 50-mndandanda wa stack, ngakhale RTX 5060 yolowera.

Kungoganiza kuti Nvidia amamatira ku cholumikizira (chovuta) 12VHPWR chomwe akugwiritsa ntchito pano, kugwiritsa ntchito mphamvu kwambiri kumakhalabe pa 600W. Chombo cha RTX 5090 chikhoza kupitiriza kuwona kuwonjezeka kwa mphamvu yokoka ngati ikupereka ntchito yowonjezereka, koma idzafunikabe kusiya malo ena owonjezera, kotero kuti 500W yochuluka ikuwoneka yomveka.

Pamndandanda wonsewo, ndizotheka kuti Nvidia ayesa kusunga zinthu mosamala m’malo mokakamiza kugwiritsa ntchito mphamvu zambiri. Monga adanenera NotebookCheckMchitidwe wamakono wa Nvidia wowonjezera mphamvu zonse za bolodi (TBP) akadali atsopano – makamaka pa makadi monga RTX 4080. Zakale, makadi a xx80 anakhala bwino pansi pa 300W, ngakhale kutsika pansi pa 200W nthawi zina. M’mibadwo ingapo yapitayi, RTX 3080 ndi RTX 4080 zonse zidakankhira TBP kumtunda kwatsopano, ndipo iliyonse imafuna 320W.

Ndi kugwiritsa ntchito mphamvu kwambiri monga chonchi, sizikupanga nzeru kuti Nvidia apitirize kukankhira mawotchi apamwamba kwambiri, makamaka kuona ngati AMD ingathe kuisunga bwino mu RDNA 4. Ngati Nvidia akuyimba kumbuyo pang’ono, titha kuwona RTX 5080 yokhala ndi TBP yozungulira 250W mpaka 280W. Komabe, ngati Nvidia ikamatira ku chiwembu chake, ikhoza kupita mbali ina ndikugunda mpaka 350W.
