Molex crimper?

One thing has led to anot....nope...one thing led to a train wreck. Wanted to upgrade the CPU in my desktop. Got an AMD Ryzen 9 3950x. AMD suggested a minimum 240mm liquid cooling set up. A 240mm radiator was not going to fit in my old case so I bought this monster of a case....
The Tower 900

Goes without saying that very few, make that none of the power cables from my power supply reach so I have decided to just make them myself. I need a pair of crimpers that work on Molex terminals. Any suggestions?
