Earlier in the year , MSI started to showcase a simple yet innovative safety measure—involving the heavily debated 12V-2x6 connection standard. In a completely serious April 1 social media post, the brand's gaming division refreshed its audience's collective mind: "did you know? MSI graphics cards come with a special dual-color 16-pin PCIe cable! If you see yellow, your connection isn't secure. Make sure to connect it properly, and game on with confidence! Note: this dual-color design applies only to the 1-to-3 and 1-to-4 dongles." TechPowerUp's news section has covered multiple instances of 12V-2x6 cables—and an especially fault-prone predecessor: 12WHPWR—being subject to unfortunate high temperature accidents. Yesterday, an unlucky owner shared details and images of their personal experience—involving their eye-wateringly expensive MSI GeForce RTX 5090 SUPRIM SOC model, the card's bundled cable, and a Super Flower 1300 W ATX 3.1-complaint power supply unit.

This incident was documented via a Quasar Zone BBS thread—circumstances were described as follows: "it's bitter. (My computer) kept turning off with a blue screen, so I checked and found out that the connector was burned. It's a shame... I played a game (Black Desert) that uses about 400 W for about two hours, and it happened yesterday...I need to file an AS complaint." Despite being firmly inserted—i.e. no yellow sections being visible—MSI's "foolproof" design did not prevent the melting and burning of this particular cable's graphics card-bound end connector. Fortunately, the SUPRIM SOC card's power input appears to be unaffected—the owner and several commenters surmised that a defective cable was shipped with this ultra-premium product. As pointed out by Tom's Hardware, the yellow-tipped safety measure is merely a "visual aid"—so underlying faults could still occur. ZOTAC's engineering team explored a more in-depth solution; their " 12WHPWR Safety Light " feature debuted during CES 2025.
