Seasonic suggests using a hairdryer when connecting their power supply to a GeForce RTX 40

Seasonic, one of the most prestigious power supply manufacturers, has started recommending users to use a hairdryer when connecting their NVIDIA GeForce RTX 40 GPUs. Just yesterday, we learned that CableMod announced the withdrawal of its 12VHPWR adapters, which still run the risk of overheating and melting. Now, a power supply manufacturer is warning users.

Specifically, Seasonic, in its recommendation guide, explains to users how to use and install the new wiring with the 12VHPWR and 12V-2×6 connectors on NVIDIA GPUs. The reason is evident – to avoid bad connections that lead to a burnt connector and damaged graphics cards, which, in the worst case, can exceed €2,000. On the other hand, it is also confirmed that this new wiring is also very prone to damage if it is slightly bent when installing the graphics card on the computer.

Why does Seasonic recommend a hairdryer when installing your NVIDIA GeForce RTX 40 GPU?

Seasonic states that if you need to move or bend the cable in any direction, it is better to use a hairdryer to apply heat, which makes it easier for the cable to bend without causing damage. Nevertheless, Seasonic advises against bending the cable or exerting excessive force during installation. However, they also indicate that you should firmly press the connector until it clicks. They even suggest that if you want to bend the cable, do it at least 35 mm away from the head.

This means there are several things to consider when using this PCI-Express 5.0 wiring, which has debuted only on NVIDIA GeForce RTX 40 graphics cards. It is not surprising that almost all partners offer graphic models with 8-pin PCIe connectors. However, most problems have occurred in the GeForce RTX 4090 – the most powerful model, but also the one that demands the most energy.

Recommendation on how to use our 12VHPWR / 12V-2×6 cable

All connectors must be INSERTED, LOCKED, and SECURED correctly to prevent issues.

DO NOT bend the cable in any direction once plugged in.

DO NOT bend or apply force to the cable too close to the connector.

We understand that it may be necessary to bend the cables to fit them in the case. If this is required, follow these recommendations:

Disconnect the 12VHPWR / 12V-2×6 cable from the power supply and GPU card.

Carefully use a gentle heat source (such as a hairdryer) to heat the cable area where you want to make the bend.

Carefully insert the connectors into the power supply and GPU.

Ensure that the connectors are properly seated, and the connectors’ latch fits and locks in place with a click.

It is vital that once the connectors are well positioned, do not bend the cables or exert any unnecessary force on the connectors, neither on the power supply end nor the GPU end.
