Ok so I need to upgrade the power supply in my dell 9020 tower I’ve found this insignia 520 watt it has everything I need expect one connector so what I need is two 6 pin connectors for the gpu which it has two 4 pins which I’m gonna use as an 8 pin connector for the motherboard and i need another 4 pin connector so since I’m using the 8 pin for my motherboard and not the 24 pin connector it comes with can I just use the 4 pin that connects to the 20 pin for my mother board as separate like only use the 4 pin let me know what you guys think as I don’t know much about motherboard connectors
