People, you don't need much stronger GPU supplies, the onboard one is good enough and with mods it can provide what's needed.

An off-board supply is not that easy to use properly, you need to pay attention to wire voltage drop, you need remote sense, you need a way to clean the voltage of the EMI picked up by the connection wires and the hardest thing, you need to take care somehow of the poor transient response a remote supply has - especially if it's a linear design.

The onboard supply doesn't have these problems and with upgraded RC components, raised switching frequency and decent cooling it can handle exactly what the tiny 8400GS chip needs.

Not realy, power management of the xfx cards dieing in a straight line overhere,....in fact , the fets are burning literly of the cards, and cooling was sufficient (-8 air) ....if you want to go realy high you need external supply.

I have 0.03 voltage drop at 2.70v , clocks where 1070/2700/501 , biggest problem is youre psu, mine (1kw version) dropt to much on the 5v line, had to get the 620w enermax psu who was a little better at the 5v.
