ASUS sells a special power cable called the ROG Equalizer for €50 and say it stops the power plug from melting on strong graphics cards like the RTX 4090 and 5090. ASUS claims it shares power evenly between the pins, uses better gold contacts, and stays cool even at high power. But hardware expert der8auer opened it up and tested it, he found it is not smart at all. It just has a simple metal bridge inside to link the wires, no electronics to balance power. In his tests, this bridge made the power even more uneven between the pins, One pin carried much more current than others. Taking the bridge out actually made it better. The cable is also stiffer, which can bend and stress the plug in small PC cases. The gold contacts picked up tin from the graphics card side, which could cause problems later. der8auer says the cable gives only a small safety boost and does not fix the melting problem as advertised. He thinks it is not worth the high price compared to normal good cables.
