Antec True380 and P4S8X

[PokeSmot]

I'm probably a moron for asking this, but i've never built a p4 rig (p3 and earlier)...

I have a Antec True 380W ps... Do I plug all 3 power cables to the motherboard or just the 12V connection? (theres the ATX12V (4 pin), AUX12V EZ Plug (6 pin) and ATX Powersupply (20 pin))

You only need two, the 20 pin ATX and either of the other two. However, some people have reported more stable voltages when used all-3. (There was a post in Overclocking forum by Thugsrook about 4-5 months back, IIRC)
