post #1 of 9
Thread Starter 
I was planing on upgrading my mobo to M4A88T-V Evo but there is a 8pin connector i read that you can put the 4 pin in it but will it be enough if i overclock Phenom II B55 to 4Ghz

Yes.

Those adapters are absolutely pointless. They actually do more harm than good since they are adding two additional pin connections and additional cable length.
Once again...

Only potential problem would be if it's wired like some of the 1156 boards where if it doesn't have all 8 pins it won't boot.

AFAIK on AMD boards there's no issue. Those extra pins are just wired in parallel with the first four in an effort to cut cable amps.

As for how much current can go through the 4 wires... my C2 955 is an absolute power hog, my board only has a 4 pin connector on it, and I've measured an increase of 230 watts over idle at the wall in linpack at my highest overclock. If a 4 pin will handle my chip, it'll handle darn near anything not deep underwater.

I asked this same question in the past and was suggested to upgrade my old PSU before overclocking which I did. See here.

You'll be fine using the 4-pin in an 8-pin slot on most motherboards. Plug it into the left or right half, not the middle.
