In case you missed it earlier, the EVGA PowerLink is basically an adapter which allows people to move the PCIe power sockets, usually located at the top of the PCB, to the front, giving you a bit more room in low-profile cases, offering better airflow, or simply providing a better cable management.
The adapter can be used with any configuration as it is simply a matter of adding, removing or moving the supplied PCIe 6-pin and 8-pin plugs. The PowerLink also features integrated solid state capacitors so it should provide additional power filtering as well.
While it is currently still not available, the EVGA PowerLink is priced at US $29.99 on pre-order so it is nice to hear that EVGA has launched a promotion that offers a free PowerLink for all registered EVGA Geforce GTX 10 series graphics cards.
Bear in mind that it is a limited time offer so make sure to check out EVGA's promotion site and request your own free PowerLink.
