I'm going to be upgrading my system to replace both the motherboard and graphics card. Right now my rig is:
Asus A8N-Deluxe motherboard
GeForce FX 5800 graphics card
Audigy 2 Value sound card
2x Hard drives
DVD-RW burner
CD-RW burner

I'm going to be putting in (while keeping the hard drives, sound card, and optical drives):
Asus A8N-E motherboard
GeForce 7800GTX graphics card

My power supply is 400W and I'm wondering if it's going to be enough to power the new equipment as well as the rest of the parts.

Nobody can tell you, because 400W power supplies are capable of 200-460W constant load depending on manufacturer.

I've seen this a hundred times. People link to this weak PSU calculator which only calculates wattage.

In order to properly select a PSU for your Rig, you need to know how many AMPs it will potentially draw on the +3.3v, +5v, and most importantly, the +12v Rails.

"The world ends when you're dead. As long as your breathing you got more punishment in store. Stand it like a man and give some back."
 
The calculator is just to get you in the ballpark wattage wise, any other special requirements is really up to the individual to research themselves, do you want us to build the thing for them too?

Should be enough power, you're not changing it THAT much. Shoot, I was running on a 250 watt for quite some time... well, for a couple of months... with the A/C vent on it at all times... and now i have a new Mobo, case, and PSU.
