RTX 5090 Power Cables: Avoid Adapters and Extenders for Safety
Owners of the coveted RTX 5090 graphics card may be tempted to enhance their setup with stylish power cables. However, experts strongly advise against using adapters or extenders.
Aris Mpitziopoulos, CEO of Cybenetics, emphatically warns: "Do not buy adapters or extenders. They can all be dangerous."
The concern lies in the possibility of overheating and melting connections when the RTX 5090 draws its maximum power of 48 amps or more. This risk persists despite the "fixed" 12VHPWR connector (12V-2x6).
The threat does not stem from the cables themselves, as all 12V-2x6 cables are rated to deliver 600W (55A). However, some PSUs lack native 12V-2x6 sockets, instead using 2x 8-pin connectors. These require proprietary 12V-2x6 cables that may not be compatible with other PSUs.
Incorrect pairings of adapters and extenders can lead to disastrous consequences. Therefore, it is crucial to only use the cables supplied with the PSU.
This applies even to RTX 4090 users who have experienced no issues with adapters or extenders. The RTX 5090's higher power draw (125W more than the RTX 4090) increases the risks significantly.
Consider these precautions:
* Invest in a PSU with a dedicated 12VHPWR socket and cable.
* Avoid third-party adapters and extenders.
* Use only the cables provided with the PSU.
By following these guidelines, you can ensure the safety and longevity of your expensive RTX 5090 setup.
