New protection features from power supply manufacturers could be the answer to preventing cable meltdowns from occurring. It’s a new year, and PSU manufacturers are looking at new ways to avoid cable meltdowns with 12V-2×6 connectors. MSI has just released a teaser video that shows a glimpse of a PSU that hints at some kind of combined usage between a USB Type-C and a 12V-2×6 connector with a shield logo between them, teasing new protection features. The ongoing theory is that MSI is incorporating some kind of monitoring technology for the maligned power connector, which has been plagued with reports of damaged components since its inception. The video then briefly mentions MPG Ai1300TS PCIE5 and MPG Ai1600 PCIE5 power supplies, which MSI says it will share more at CES 2026.

ASRock Phantom Gaming PG-1300G saves RTX 5090 OC’d with 1350W of power, mostly
ASRock is one of the first PSU manufacturers to include at least one extra level of hardware monitoring protection for the 12V-2×6 connector. Its solution comes in the form of an NTC sensor, which will trigger the PSU to shut off power to the connector when temperatures get too high. This feature is found on the Phantom Gaming PG-1300G PSU.
A user at Overclock.net forums has reported a staggering claim of how this PSU’s added feature managed to mostly save their GPU during an extensive round of testing. User motivman had been testing their MSI Ventus RTX 5090 graphics card by giving it over 1350W of power (not hard to get which BIOS were used here) when the PSU’s protections kicked in and shut the power off. Now, before anyone gets to the obvious, most are unlikely to guess how many times the card was benchmarked at 1350W before things went downhill.
So the card had been benchmarked over 200 times before things got toasty. The owner has said that while everything still works, the card is no longer performing at the same level as before, and there is discoloration on the cable connectors. They also mention using the included green-colored cable included with the PSU as opposed to the yellow-colored cable provided by MSI.
From temperature monitoring to other protective features its clear that power supply manufacturers are looking into more ways to keep graphics cards, which use the now infamous connector, functioning.
