Are there any specific recommendations for the mini 6 pin to 8 pin PCIe power cable? I want to power a 6600 XT on a 5,1. I've been eyeing one option from a seller called TeamProfitcom on Amazon USA. Mostly wondering since I've seen on other threads that there's some janky ones with the wiring, but I don't know what to look for, and even House of Moth or the Definitive Mac Upgrade Guide don't mention much.
