EVGA's POWERLINK 41s fixes the RTX 3090 Ti FTW3's power cable problem
EVGA RTX 3090 Ti uses a PCIe 5.0 16-pin cable for power, and not many power supplies currently feature that cable. With a peak power capacity of 600 watts, the 16-pin PCIe 5.0 power cable has the ability to harness four times as much power as a standard 6+2-pin PCIe power cable, and that makes power adaptors/converters difficult.
 
Meet the POWERLINK 41s
With ARGB (addressable RGB) lighting, and power filtering, EVGA's new POWERLINK 41s reliably converts the power of four 6+2-pin PCIe power cables to a sing e 16-pin power connector. This power adaptor not only provides EVGA's RTX 3090 Ti FTW3 graphics cards with up to 600W of power, it also provides extra filtering to that power to increase system stability and reduce power ripple and noise.
 
EVGA's POWERLINK 41s is designed to offer users a cleaner cable management solution than other 6+2 pin to 16-pin GPU power converters and deliver cleaner power to their compatible RTX 3090 Ti series graphics cards. Sadly, this adaptor is made exclusively for EVGA's RTX 3090 FTW3 series graphics cards, which means that this adaptor may not work with EVGA's next-generation RTX 40 series products. That said, would you want to use an adaptor that says RTX 3090 Ti with an RTX 40 series GPU?
 
EVGA has started selling their POWERLINK 41s adaptors on their website for $59.99 (USD). 
 
I didn't see these on the EVGA website yet. 
 

Waste of money and ugly AF.

I expect the Ada Lovelace version of the Powerlink to double it to a full eight 8-pin connectors, so it can support two of the new PCIe 5.0 connectors.
