hi

I am trying to oc my 4770K but my PSU is Enermax noisetaker 485W I heard it can handle 550w +32a 12v rail. Since it doesnt have 8pin connector its connected with 4 pin which provides 75w to cpu.
Its paired with a 7950. I am not able to overclock anything over stock even with voltage increase.
Is the 4 pin bottlenecking the oc or its the cpu? Bios shows correct voltage reading when overvolting with maximus vi hero.

Thanks

well the 4770k can use 84w at stock clocks and if 1 pin has 75w you dont have enough power to run it at stock correctly then your 7950 will probs be using 100+w during use and if your psu it a few year old it will not be giving its original power anymore so you probably getting short on spare power 485w is a little low to start with to be running a system like that on and overclocks soon eat up extra power very quickly

whilst you will probally be able to get more then the 75w out of the connecter it not really advised to be running like this
