thank you for answering, so it works , but i am usinga quite powerful CPU....
i5 2500k, will it be safe and stable ? Thanks !
You're referring to the 12v EPS power connector, which comes in 4-pin or 8-pin varieties. There are some that say that running 4-pin is unsafe and will damage the motherboard power stages (folks such as jaquith). I personally used my P8P67/2500k with only the 4-pin 12v EPS power connector. It worked like a charm.
I have since added in a 4-pin to 8-pin connector, primarily because my 4-pin connector barely
reached the jack and using it as an extender was helpful. Here's a link:http://www.amazon.com/gp/offer-listing/B003F6VQ2W/ref=dp_olp_new_mbc?ie=UTF8&condition=new
Good luck! Enjoy your 2500k.
