The RTX50 series comes standard with a new generation 12V-2x616-pin power supply interface. NVIDIA also swears to ensure absolute safety. However, it currently seems that it is indeed much safer than the RTX40 series, but it is far from absolute. This power supply mechanism still has hidden dangers. HardwareLuxx tested a water-cooled version of the RTX5090 and used a thermal imager to observe the temperature everywhere.
There is no problem with the GPU core and video memory, butOn the power cord at the power end, extreme high temperatures exceeding 150°C were captured!
The power supply uses BeQuietDarkPower13, which supports the ATX3.1 specification and comes with a 12V-2x6 power cord.
Fortunately, neither the graphics card, power supply, nor power cord has been burned out, and everything is safe.
HardwareLuxx points out,This will probably always be a highlight of the RTX50 series graphics cards.
Although there are currently some sporadic cases of RTX5016 pin power supply being burned out, it seems that the reasons are different. The 12V-2x6 power supply interface is relatively safe for the time being.
However, it has also been found that the current distribution of the 16-pin power cord is not uniform, and the current in a certain line is often too high, which is a hidden danger.
In general, if RTX50 series graphics cards want to ensure safety,Try to ensure that you use a brand power supply that complies with the ATX3.1/PCIe5.1 specification and has a power of no less than 1000W. Use the original power cord or adapter cable. Do not sustain high load for a long time.
