Weird power cable configuration

[DatOneLefty]

Would it be possible to use a PSU to 3 4 pin molex cable as a 4 pin to 2 4 pin? My 2 riser cards use the 4 pin molex and I don’t have PCIe power to 2x+ molex.

Basically it comes down to how many amps you are passing over the wires. They use more than 1 plug so no chance of the wires getting too hot. Using only 1 plug could lead to melted wires and shorts, fire, etc.
