Intel Core i5 2500 - 4 or 8 pin power?

post #1 of 8
Thread Starter 
My motherboard (MSI P67A-C45) had a small cover on 4 of the 8 pins for the CPU power, without thinking I took it off and connected all 8 pins.
The PC works fine, but does my CPU really need 8 pins or are 4 enough?
Just to make it clear, it's the non K version.
Thanks and sorry for the dumb question.

It will work fine with either

What he said, either is fine.

Also when you get a chance, fill in your system specs under "User CP"

I didn't expect this answer.
I guess I'll leave both connected so I don't have a cable hanging around.
Thanks. +rep

Done, thanks for reminding.

You've got a nice system. I like your clarification on the CPU too

Even if you can't overclock it very much, that 2500 could probably still beat most all of the C2Q's out there, and some of our first-gen i7's.

Yeah, I know. My previous CPU was an Intel Core 2 Duo e5200@3,1GHz, so I've made a huge jump in perfomance.

Either will work, but for heavy overclocks the 8 pin has the capacity of delivering more power.

More importantly, the resistive drops through the wire will be lower allowing the VRMs to have a much lower duty cycle, helping thermals and ripple.

The 4-pin would likely continue to source current until the wires melted, but the overclock would fail before that happened due to the aforementioned delivery issues.

Though none of that matters in this case.
