Now the problem is I cannot remember how to calulate these last figures yep I am because I know how to to this but I'm having a silly moment or should I say a senior moment. If my memory serves me correctly the total amout calculated together for the +12V RAILS is the total amout of amps per RAILS.

I have heard of this one before and it pretty well on the ball when it comes to calculating the PSU... thanks for the link. WOW I was pretty close with my calulations and I even added my upgrade fro the GFX card as well.

Recommended Wattage: 792 Watts

Sorry, but as was stated earlier, these online calculators are 'ballpark' at best and usually not a very good reflection of what is required.

I can also guarantee you, that the spec above will not draw anything even close to 792W.

BTW...to calcualte what Amps a PSU will provide, you need to take a look at the sticker on the side of the PSU.
Ignore the retail stated Watts (as that is a peak power). Look for the other number which states the continuous available wattage.

Once yu have it, divide that by 12 and thats the amps the PSU can supply continually.

I agree with above. I don't trust those calculators.

how much did ypu pay for that 3 day thing?
you could've just bought a power calculator that you plug into the wall
