Review on 🔌 CableCreation 5-Pack 6-pin to 8-pin PCIe Express Power Adapter Cable - 4 Inches/10CM: Enhanced SEO-Optimized Product Title by Kimberlee Winn

Worked great from an old 800w PSU to powering a 2080 Super GPU. Make sure your power supply is big enough to power what you customize to your needs. Performance specs are easy to find for anything PC related. While this connector is valuable to a PC manufacturer, it allows you to connect the wrong voltages. It's not magic, it's mechanical wiring. Know what you're doing before you do it!
