8-pin / 4-pin CPU power connector

post #1 of 9
Thread Starter 
My psu has a 4-pin, I just ordered a new motherboard ( EVGA 122-CK-NF67-T1 ) and noticed it has an 8-pin. Is there an adapter?

yes there is an adapter but don't use it.

you see the 8 pins on the mobo take two 4pin connectors. they are there so that that mobo can draw more current safely. meaning they are all connected in parallel. they were created mainly for servers and high end desktop cpus -> dual core and quad core.

if you get an 4 pin to 8 pin converter you are defeating the purpose of the 8 pin connection. you are taking all the current and splitting it in to 8 wires, when the current stays the same.

you should just plug in the 4 pin connector into the port - leaving the other 4 pins empty. if you have a power hungry cpu, or plan on overclocking you might want to look in to a PSU that actually has the 8 pin connector connected to the power source.

There are adapters.

It's just that you should make sure you psu supports it.

the 4 pin is designed for something like 75 watts (correct me if wrong )
And the 8 pin doubles that.

So the best of advice is getting another psu

EDIT: You beat me too it

thanks for the replies. I agree might as well get a new PSU to go with the SLI board. That way I could add a second video card in the future. Might get a new case and a core 2 duo as well, they are so cheap right now. I'm thinking the E6420 for $187.

Ditto...if you plan to overclock at all you must have a PSU that will power the board correctly.The Evga manual says a 4 pin will work,but strongly recomends using an 8 pin.Good choice BTW on the 6420,dropped mine in and clocked it to 3.2 off the bat,been solid ever since,great performing chip
best regards,
Scott

if you get an evga board and plan to overclock i recommend you get a stong psu with a 8pin cpu power connector,

if you plan to overclock with a 8 pin mobo then i strongly recommend you get a 8 pin cpu power connector psu
