I need this because my board needs 8+4 pin CPU power. My power supply only had an 8-pin, but it split into two ends, which could also be split into 4+4. Good padding hides the wiring. I couldn't find another that shipped quickly, had a protective sleeve, and had a 4+4 (2x) split. A NOTICE. Make sure your processor's power rail on the power supply matches the processor's power rating!
