A Chinese manufacturer has come up with a 12VHPWR adapter featuring active chilling and real - time power monitoring , aim to extenuate concerns of melting GPU tycoon connective . The unparalleled angle adapter is claimed to improve safety by handle two major issue : cable deflexion and excessive oestrus . Unlike traditional connectors , which can be strained by tight case layouts , this adapter boast a 180 - degree design , reducing cable television stress and derogate the risk of poor seating room .
Additionally , the adapter features an incorporate cooling fan to actively dissipate heat , a first for GPU power connectors . It also includes an LCD screenland that allow for real - time temperature and power usance monitoring , helping users detect likely overheating before impairment occurs . The transcriber is currently sell on Chinese online shopping platformTaoBaofor around $ 30 and is compatible only with the RTX 40 - series GPUs , as there is no quotation of any RTX 50 - serial publication products .
Notably , third party cable system manufacturers includingEzdiy - fabandCablemodhave introduced 12VHPWR adapters with heatsink answer . While these adapter may or may not offer a workaround for current RTX 40 - series possessor , the long - term solution lies in Nvidia ’s shift to the 12V-2×6 standard for future GPUs .

The 16 - pin 12VHPWR power connection has been a point of controversy since its introduction with Nvidia ’s RTX 40 - serial GPUs , particularly the flagship RTX 4090.Reports of connectors meltingdue to unreasonable heat buildup and piteous transmission line seating have raised concerns among personal computer gamers and fancier . Users account instances of 12VHPWR connectors overheat and , in uttermost case , melting .
investigating advise that wrong cable interpolation , combined with high might draw , pass to increased resistance , sire excessive heat . Nvidia initially claimed that ensure a in full seat connection would forbid failures , but veridical - world cases cover to come on , pass to further examination of the connector ’s pattern .

The event prompted regulative bodies and tech experts to examine the power delivery system . PCI - SIG , the chemical group responsible for power connector measure , afterwards introduced therevised 12V-2×6 connectorfor the RTX 50 - serial , designed to improve power efficiency and safety . However , many RTX 40 - series cards , remain vulnerable to the original problem , necessitating aftermarket solutions .
Despite the new RTX 50 - serial publication adopting the revised 12V-2×6 power connector , thaw business concern stay . It was discovered that using sr. 12VHPWR cables with the RTX 5090 can still lead to overheating issue . This became evident when aReddit exploiter reportedthe first recorded meltdown of a 16 - peg connector on an RTX 5090 while using a premature - gen third - political party cable . The cable television manufacturer later clarified that only its 2025 - made 12V-2×6 cables are fully compatible with RTX 50 - serial GPUs , despite the new connector being backward compatible with 12VHPWR .
