Go to solution Solved by ImWilly,

Dual CPU power plug is usually used for overclocking the CPU, most notably for high end Intel CPU

PSU manufacturer does that more often as a way to reduce cost for cables instead of providing 2 separated cables

 

If you don't use Intel high end CPU, you can just plug one of connector to the motherboard, just make sure to see the labels on the cable so that you won't plug the connector the other way around

It does no harm to plug both Dual CPU connector to the motherboard as well, at least less cable hanging on your rig

So i got a aerocool inverter 750 80gold and it has a cpu cable as 8 pin to dual 8 pin. Since this my first time building a pc i dont know how to connect them. do i connect the dual 8 pin side to motherboard 8+8 pin cpu power part? it makes me confused bc my psu doesnt have 2 seperate 8 pin for cpu but motherboard has two 8 pin for cpu power. Rn i only connected one of that dual 8 pin side to motherboard cpu power pins. Cable is shown in image . Sorry if its a dumb question

That's what you get with entry level Gold units. Daisy chained CPU cables are useless because they can't provide more power than a decent single 8 pin.

doesnt matter since theyre daisy chained

 

besides you dont need a dual 8 pin since a single eps can probs handle 500w+ no issue judging by all those old x58 era hwbot subs on boards like the rampage ii, just some stupid marketing nonsense with boards that have useless dual 8 pins on consumer hardware

 

for hedt stuff like threadripper definitely needed since those things draw a ton of power but you probably wouldnt be buying a <1000w unit for those
