4 pin atx 12V power connector

I have been using just the 20 pin connector for the past 1 year. OC'ing my 2500+ to 3200+ at 1.75 Vcore.

I have only been using the 20 pin connector. Putting the OCing aside, I have always been taught to use only the 20 pin power connector for amd xp systems. To my understanding the 4 pin atx 12V power connector is for Intel systems. Is this accurate? Am i undervolting my board?
 
Well that board has the ATX 12V connector, so you should be using an ATX 12V supply for the best stability and performance.

The idea that only P4's needed the connector was put forth as a bit of Intel bashing.
 
If it's there, it should be used. AMD has recommended running the CPU off the 12V rail for a long time, but it is just recently that mobo makers have started using the P4 connector on their mobos for AMD. Using it makes for more stability and spreads the load more evenly among the PSU rails. Also allows for using a lower powered PSU successfully. With it you could run with a good brand 250W PSU - without it, you might need a good 350W unit or better.
.bh.
 
I would hate to think a mobo mfg made me pay for a connector and circuitry and mobo engineering that I didn't need. 😀
