In case you didn’t know, the new generation of Nvidia graphics cards leaves behind the familiar 8pin connections. Alternatively, the cards can run at up to 600 watts from a single connection, the new PCIe 5.0 12VHPWR power connector. This connector is only present on the latest generation ATX 3.0 power supplies, so computers with older PSUs require the use of an adapter.

Typically, the 12VHPWR connector is designed to deliver up to 600 watts to the graphics card. However, the 8pin connector is only designed for 150W. Thus, in cases where the consumption reaches 600W or 450W, it has been observed that more than the recommended load can pass through the 8pin connection, if a 16pin to 2x8pin splitter cable is used. At the same time, the load is not well balanced even with 16 to 3 x 8 pin splitter cables.
