4-pin ATX-12v, or 8-pin EPS +12v plug in an EATX-12v mobo?

My new power supply for an ASUS P5B board has two 4-pin ATX-12 plugs. The cpu is Intel Core2 E6400 (no tweaks). The manual never explains more than what you can do. In this case, the board takes 4-pin, or 8-pin. I think the two 4-pins will fit the 8-pin configuration.

Is there any advantage to using a full 8-pin configuration?

The state of technology has moved on in the three years since my system was one of the leading edge systems. The above is new stuff to me, so please forgive a dumb question, if such.

Thanks,

The additional pins gives a greater current capacity across the connector. This is only a factor if the CPU can draw more current than a 4 pin connector can handle. This will never be an issue with the CPU you are using. It's really only a potential issue with older (pre Conroe) high power consumption CPUs.

If you do have 2, 4 pin leads from your PS and an 8 pin connector, then connect both. If you only have one 4 pin connector then don't worry about it.

Thanks, B_r. It has run fine with 4-pin setup, so I won't worry on that part.

Right now I am having posting issues, after a malware attack. Trying to chase down that gremlin.....
