Default P5K Deluxe WiFi-aP power supply

Ok, new machine time. One 'new' thing since the last time I did this.. The
ATX 12V 4 Pin socket is now optionally an 8 pin.. EATX 12V.. I can
understand that this would supply more power to the board.

But why or what would be the reason to have to op for an 8 pin power supply
over an older model with just a 4 pin.

Will be running a E6750, Kingston Hyperx 1066 mem, still looking at video.
Some where in the 8600 gts or 8800 gts series. Single SATA drive w/DVD
burner...
Least I don't think I'm going to run a RAID drive setup... depends on where
what ,, price I find drives at..

TIA

You use the 2x4 connector type, if the processor TDP power is going over
130W. Now, the highest power draw, at stock speed, of an Intel processor,
*is* 130W. So that means, for stock processor operation, there is no need
to use a 2x4. Even a P4 at 3.8GHz would still only need the 2x2 connector.

A while back, people were using D805 processors, and overclocking them. This
thing was cheap and fun to play with. Overclocking from 2.66GHz to 4GHz
was possible, with enough cooling.

If you were to do that, the power consumption when running at 4GHz,
is more than 200W. In such a case, you'd want to use the 2x4 connector,
as the 2x2 connector would start to get warm and the plastic could
melt.

When overclocking that particular processor, someone placed their motherboard
on top of some foam while experimenting. The Vcore regulator
got so hot, that it melted the foam sitting underneath the motherboard.

So if you're doing stuff like that, forcing the motherboard to crank
out immense amounts of power, that is when you get serious about the
2x4 connector on a desktop board. For more conventional, tame usage,
the 2x2 is enough.

Ok that makes cents' .. looks like the E6750 TDP is 65W so I may have quite
a bit of room using the 2x2 connection.
