Those who follow the RTX 40-series on the internet are aware that CableMod was the first business to release 90-and 180-degree adapters for the 12VHPWR cables used by GPUs in the 40 series. By directing the power line straight down from the GPU or pointing it towards the motherboard, the adapters made it possible for 40-series cards to have neater wiring because they stopped power wires from being bent out of the way when the side panel was mounted. Regretfully, CableMod’s initial adapters had a unique set of issues. The business has since introduced version 1.1 adapters, claiming that these have undergone numerous noteworthy improvements.
The business used Twitter to announce the release of their new angled adapters, noting that version 1.1 has several improvements and is currently accessible everywhere. The most notable modification is that CableMod claims to have been changed to a 12V-2×6 connector, also known as a CEM 5.1 standard female connector. This is effectively the 12VHPWR interface’s second iteration, and it promises to consign all those annoying melting problems to the annals of history. This is because of a number of internal modifications, one of which is the relocation of the sensing pins within the housing, necessitating a 1.5 mm deeper insertion of the cable in order to establish a connection. This connector is quite promising because it operated quite cold in a prior test, even while partially inserted.
Furthermore, according to CableMod, it enhanced the tightness with which the male connection enters, so guaranteeing a secure fit. It’s odd because the adapters were meant to assist solve this issue, but Wccftech claims that the prior adapters were a little loose in some systems and may have burned up. Users weren’t fully inserting the 12VHPWR connector, which wasn’t necessarily a problem with them because it was difficult to determine if it was entered all the way. This was the whole problem with the connector in the first place. Even when partially plugged in, the GPUs continued to function. Due to this power supply interruption, a lot of cables and GPUs were sacrificed to the gods of bad connector design.
The new female connector, which should resolve all the problems with the entire generation of the original 12VHPWR cables, is the biggest change, despite all the fanfare. AMD decided to simply use standard 8-pin connectors on all of their 7000-series GPUs because this has been a persistent issue for owners of 40-series cards. But as GPU power requirements rise over time, AMD will probably need to move its 8000-series GPUs to a 12+4 connection. That is, if it even produces a card that needs a lot of power. It’s still unclear as of late 2023 whether AMD would follow this path because it’s been reported that it will give up the upper hand to Nvidia in the upcoming round so it can concentrate more on AI cards.
