I have received an official statement from Cooler Master on the issue of the faulty 12V 2×6 cable, which clarifies some points and responds to the criticism of the original design. According to the email, Cooler Master explicitly acknowledges the problems with the previous angled connector design. Although this was developed to improve cable routing in tight housings and reduce bending forces, it has proven to be incompatible in practice, especially with graphics cards with recessed or shielded power sockets.
The manufacturer has announced that this angled version has now been completely discontinued. Future power supply units will only be supplied with a straight 12V 2×6 plug. Cooler Master also emphasizes that the previous support recommendation that users could adapt or modify the plug themselves no longer applies. All regional support teams have been instructed to discontinue this practice immediately. Instead, affected customers will in future receive a replacement cable in the correct version on request.
The email also states that there have been no reports of damage caused by user modifications to date, but that it is agreed that such a procedure is not safe. According to Cooler Master, the new cables should be universally compatible and also have a two-color plug-in indicator that makes an incomplete connection immediately visible. Cooler Master expressly thanks me for my analysis and describes the article as an important impetus to improve the safety of its own products. The company is also offering a technical meeting with the PSU team to present the revised design and internal tests.
Below is the original text of the email (excerpt):
… Here is our official clarification and update:
Current Product Status
- All newly developed Cooler Master PSUs are now equipped with a direct 12V-2×6 connector.
- The previous right-angle version is being phased out and is no longer used in upcoming models.
Why the Right-Angle Connector Existed
The original design aimed to:
- Reduce cable bending stress
- Improve visual cleanliness and cable routing in tight cases
However, with some GPUs, this created clearance issues, noted in your article.Safety & RMA Handling
We want to be very clear:
We do not recommend users modify or alter the cable.
- The previous RMA guidance suggesting a “DIY adjustment” should not be followed.
- We have instructed all regional support teams to stop recommending this practice.
- For any user experiencing compatibility issues, support will now provide a replacement vertical 12V-2×6 cable.
To date, we have not received any reported customer damage cases arising from modifications, but we agree that modification is not a safe approach and have acted accordingly.
Quality & Testing
Our newer 12V-2×6 implementations now include:
- A universal fit design compatible with all GPU power socket layouts
- A two-color insertion indicator to ensure full seating and reduce risk of partial connection (purple visible = not fully inserted)
We appreciate your testing and feedback, articles like yours are an important part of ensuring the industry moves towards safer, more reliable solutions. We are committed to improving based on real-world experience and open dialog with the community.
If you are open to it, we would welcome a short follow-up call with our PSU PM and technical team to walk through the updated design and testing improvements.
Thank you once again for your thorough review and for highlighting an area where improvement was needed.
