For those who want to be on the first wave of RTX 40 series graphics cards, remember to see if the power supply can drive, there are two layers here, one is the power and the other is the graphics card power supply port. According to NVIDIA’s recommendations, the RTX 4090 recommends a power supply of at least 850W (rated).
As for the graphics card power port, there is one more point to note in particular, as there are very, very few power supplies (ATX 3.0 standard, adapted to PCIe 5.0) with native 16-pin (12VHPWR) graphics card connectors on the market, so most cases have to use adapter cables.
In the case of Sony, for example, the graphics card comes with a 4×8 Pin to 16Pin adapter cable, but the manufacturer specifically reminds that it can only be plugged and unplugged up to 30 times.
