Nvidia’s RTX 50 series, which has an important place in the video card market, came to an important security warning about graphics cards. The third -party power cable manufacturer Moddiy, 2024 and before the 12VHPWR -connected special cables produced on the RTX 50 Series graphics cards announced that the graphics cards. The company said that the new cables produced in 2025 have successfully passed the compatibility tests with the RTX 50 series, but that old models can carry risks in the use of these new generation graphics cards.
Modiy emphasized that the RTX 50 series of 2025 produced cables, especially RTX 5090 and RTX 5090D models, are updated to meet the increasing power requirements. It is stated that new cables contain significant technical improvements such as improved connection ends and thicker wires. These changes aim to prevent accidents due to high power consumption.
New generation cables and transition to 12V-2 × 6 standard
Modiy’s new cables are produced according to the most current 12V-2 × 6 power connection standard. The old cables are based on the original 12VHPWR standard and therefore may be incompatible with the RTX 50 series cards. The company has announced that it offers ATX 3.1 and PCIE 5.1 support on its new cables, has a capacity of 675W and has a “H ++” label. This new label symbolizes full compliance with 12V-2 × 6 power specification. The “H+” marking used in previous generation cables indicates that it is produced according to the old 12VHPWR standards.
The structure of the new cable has three 8-pine input connectors, which are connected to a single 12V-2 × 6 connector. Thus, users with old power supplies can directly connect to the adapters that come with Nvidia’s RTX 50 series GPUs. Modiy aims to reduce compliance problems and increase security in power transmission.
The high power attraction of RTX 50 series graphics cards can cause heating problems in old standards cables. Nvidia started its transition to 12V-2 × 6 standard in 2023 with RTX 4070 and RTX 4090 models. However, the higher power requirement of the RTX 5090 led third -party cable manufacturers to new standards. For this reason, Modiy recommends that all users use only 2025-produced 12V-2 × 6 cables.
The first reliable reports that the RTX 5090 may occur at the power port of overheating and melting problems, emerged with the melting of a modd -cable. The cable in question had only 600W capacity and was previously used in RTX 4090. After this incident, the famous German speed exceeding and PC hardware specialist der8auer, RTX 5090 cables in certain cases heated up to 150 ° C in certain cases. It is thought that warming can be caused by imbalances in the power distribution. However, some system integrators say that this problem cannot be reproduced in any case.
RTX 50 Series graphics card users are recommended to avoid using the old generation 12VHPWR cables and only the new 12V-2 × 6 specification is recommended to choose cables. Nvidia’s latest graphics cards, especially the RTX 5090, have high power traction, the use of old cables can pose serious risks. It is of great importance that users prefer compatible power cables for long -lasting and safe operation of graphics cards.
