Seasonic, a widely popular PSU brand, has recommended its customers use a hair dryer when bending a 12VHPWR or 12V-2x6 connector cable.
The 12VHPWR connector cable fiasco just continues with CableMod recently recalling all of its angled-cable product lineup due to potential GPU damage and user harm. The connector cable is updated to the newest 12V-2x6 standard (CEM5.1) but despite that, it still requires some cautionary steps to prevent "potential" damage.
In a recent recommendation guide, Seasonic has released a statement explaining to users how to use and install the 12VHPWR & 12V-2x6 connectors cables to their GPUs. The GeForce RTX 4060 Ti is the last card to use the new connector interface while the RTX 4070, RTX 4060 Ti, and RTX 4060 come in both 8-pin and 12VHPWR designs. These cards were updated to the newer 12V-2x6 cable interface which fixes most of the issues encountered with early 12VHPWR designs, especially on a lot of RTX 4090 GPUs since those used the earliest specs of the standard.
Almost all of the burning and melting issues so far have been related to the RTX 4090 GPU since it has the highest power rating amongst the RTX 40 GPU family. These cards are massive and in most cases don't have ideal room to support such designs, leaving crammed-up setups. Unlike the older 8-pin connectors, the new 12VHPWR/12V-2x6 cables also need to have a 35mm clearance before any bend is applied for cable routing. This means that the side panels in most cases will interfere with the connector.
Seasonic recommends the same 35mm clearance space in its guidelines and also suggests that any bend beyond 35mm should be done using a gentle heat source, such as a hair dryer. The area that needs to be bent should first be heated and then
