By far. I have that PSU, actually. Hasn't failed me once.

I doubt it. 2 gigs more requires barely any more power, and an 8800 GT doesn't require too much power (to my knowledge). I know people with 8800 GTX's in SLi and only have 700w PSUs.

It should be fine (even with the etra 2GB and SLI) but if ur at all concerned it isnt much to boost it up to a 800Watt. that way u will be taking no chances.

Wattage has nothing to do with anything.

Amperage is all that matters.

Wattage is the product of voltage and current, so amperage directly correlates with wattage in ATX power supplies, since ATX specifications set the voltage across the different rails in stone. What's important is how the current is distributed across the rails.

Wattage has a lot to do with everything. It's the total rating of how much power your supply can feed your components. The trick is to know how much power you can pull on each rail. Which sucks having to research.

All you have to do is find the maximum combined power on your +12v rails (or those of the prospective power supply) and divide it by 12.

650W would suffice.
You didn't list any HDD's, though I doubt you have more than two so it's not a problem.

Takes more time than simply knowing that an E6600 is better than an E6400. Typically you'd want to do U*I to get P, rather than U/I, which would give you R, if I remember my Ohm's Law correctly.

Meh.

I would feel safer with lower watts with higher amps than higher watts with lower amps.

Yes, i dont have to read it because 750 wats will power anything, even a small microwave, i mean wtf...

Quality before quantity. Make sure you buy a respected make over a shitty make that claims to be able to power a small residential estate.

As you should be aware a video card cannot drain more than 75W from the PCI-E slot. Now add on 2 - 6pin power connectors, they are 75 watts each so we have a total of 225W. (this why you need to check you 12V rails as alot of power needs to be on each one)

Even if you Sli thats only 450Watts, add the most power hungry proccessor 600Watts max. 100Watts free to power optical drives and fans. This is where we hit the slight snag.

Im assuming you want a mini fridge built in now these are quite power hungry 400Watts for the fridge/freezer and now, you need 1100 Watts.

Hmm, damn it i knew i would need a small generator to power this.
