Cooler Master 850W fanless power supply is equipped with a 450W 12+4Pin module cable and claims to support NVIDIA RTX 5090 graphics card

According to news from this site on August 6, Cooler Master stated on the product page of its X Silent Edge Platinum 850 fanless power supply on its official Amazon platform e-commerce store that the power supply supports Nvidia’s unreleased next-generation flagship graphics card RTX 5090.

It is worth noting that according to the product introduction, the 12+4Pin graphics card power supply module cable equipped with this power supply can only provide 450W power supply, not the highest power 600W version.

If Cooler Master’s statements on graphics card support and module line power supply capabilities are correct, it means that the rated power consumption of the NVIDIA RTX 5090 graphics card will not exceed 525W (Note from this site: 12+ 450W for 4Pin plus 75W for PCIe slot).

This calculation result is also in line with the 500W TDP power consumption set by another power supply manufacturer Haiyun for the RTX 5090 on the official website power calculator.
