Gloomy stories revolving around RTX 40 cards and power supplies are overblown.
A couple of other rumors have also been debunked – though we’ll need to wait until the cards are in the hands of millions to be 100% sure. The first relates to the durability of the PCIe 5.0 connectors, which is officially rated for 30 connect cycles. That is the same is it has always been pretty much. As a reviewer changing GPU connectors just about every other day, I can confidently say that connector durability should not be a problem.
The last significant rumor revolved around the possibility of an overcurrent or over power risk with non-ATX 3.0 PSUs and the new 16-pin power connector. Nvidia says it encountered an issue with a single supplier early in development, which has since been rectified. However, this last point illustrates the need to use a good quality PSU from a reputable brand. A no-name OEM model may not stick to PCI-SIG guidelines as strictly as a well-known brand would.
The takeaway seems to be much like it has always been. A good power supply is a long-lasting component that’s perfectly capable of handling your RTX 40 build. As long as it meets the minimum wattage requirements, you should be fine. Add more power if you plan to OC and handle the power connectors with care and you should have no problems.
