Upcoming 12+4-pin cables for GPUs will solve the burn-in problem
Development of a new cable for the 12VHPWR connector to prevent it from causing burn-in on graphics cards continues, and its successor could soon see the light of day. The cable that is running to be its replacement already has been tested in the laboratory and seems to have resolved the overheating issues when not inserted correctly.
The original design of the 12+4-pin power cable that is currently used for NVIDIA GPUs of this generation reported a widespread problem when it was not inserted correctly. At the beginning of this year, a revised version of the cable was announced.
The 12VHPWR cable problem would have been solved
Throughout the tests that have been carried out, it has been reported that it maintains a stable temperature without heat. This would mean that it will probably fix the problem permanently. Test site Hardware Busters was able to test the new cable at Linewell, which makes cables for Asus. They examined the latest version in action, connected to a test printed circuit board with monitoring equipment. They tested both the power output and the temperature of the physical cable itself and the connection point.
When fully inserted, the portable temperature meter showed the cable operating well at a stable 46,3°C, with a power output of 644 watts. By moving the connector a little, it worked at an even lower temperature, about 41º C, while the voltage remained the same.
This new 12VHPWR cable would be called 12V-2×6. The main difference is that the pins have been moved back 1,5 mm in the connector. This will force the user to push further on the cable to establish contact. According to Hardware Busters, the pins are also more conductive, to reduce resistance and thus keep the pins lower. Finally, the new spec can also transmit more power, up to ~660W, up from 600W in the original version.
