My PSU enough for gtx480?

Why not get a properly powered platinum PSU for $75 less in the first place then you dont have to make up the cost and STILL have the platinum level efficiency... THAT makes sense. Buying a KW of power when you dont need 500W is a HUGE waste of money and makes ABSOLUTELY NO SENSE WHAT-SO-EVER.
BUT this isnt about that.. Lets get this thread back on track. Ivy my advice is to do the math. We did and know the outcome.

How much cent/kW for a household? All i found is industry charges. 5 cent/kW, but i bet a household will have to pay at least three times more (because world was never fair).As I mentioned, we used Australian power rates in that thread, which are some of the highest in the world.
US charges vary a lot dependable on location but average is below 10 cent/kW which is below average (compared to other industry nations), so i understand why US dont care to much about power.

Measured in kWh. You pay for energy, not power. Power is kW, energy is kWH (kilowatt-hour).
US electricity rates are also not that high.
Electricity rates in Queensland, Australia, are 25.378 AUD cents.

7-8 cent? Oh dear thats almost free compared to what i pay. Guess you mean 25 cent in Australia, so 5 times more than industry, seems like lobby work well done.
Obviously i mean 1 kW a hour. Energy is a kind of power, in that term you say that energy is measurable quantity while power is a source of certain strenght. Sounds correct for economics but hard to take over to mother nature. Usualy its been told that the sun is giving energy, but is that a measurable quantity? That quantity will vary a lot dependable on countless factors so its not a fixed value. As long as that energy isnt measured its a variable continous power (of nature) with a photon source.
Ok now i say that the power is giving energy, but the energy is still not measured at that point. So, energy itself is still not a measured value, its just a certain condition. Ah well... matters are never easy to understand, i feel. To be correct, you have to tell me that i pay for measured energy else i might still forget to add the hours.

Well, ok, first text has been solved.
Its correct that time is canceling out because we already did set a specification, but energy itself isnt bound to a time value, its just a certain condition such as you said "capacity to do work". I never used any form of time, when i say "kW (related to power)", its witout time so its neither power nor energy when trying to be stick to your description. Its in that term simply a certain spec of a source. Actually its still a certain power because time is continuos so we can cancel out time.
Finally thinking logical, kW/H is the rate of energy a hour, resulting into energy, so we can call it energy. Now thats not the rate, thats simply energy with a spec (measured). So kW itself would be power because its the rate of energy, its continuous 1000 W, so it must be a certain rate. Never took that stuff to serious but still interesting to see it from a more technical view, can give some more understanding into handling it so i dont make silly failures.
Anyway, its joyful to see someone with some knowledge in physics, i was never dealing with, so i hear lot of new stuff.

Here we go, run-down of power and energy.
Power = Energy/time. In units, Watts = Joules per second.
Energy is the capacity to do work, or the change in energy = work. Both measured in joules.
Work = Force times distance.
Force = mass times accleration
Acceleration = speed over time
Speed = distance over time
All can be completely calculated. Mass in kilograms, distance in meters, time in seconds.

As long as you dont OC it will work but i would not OC, easy as that.
Time is relative because it can be affected by speed and mass.
KG is affected by mass so i kinda dont know if i can turn a certain mass into certain KG in term i dont know how it will be affected by other mass.
Even distance cant be fully calculated into meters because distance is affected by temperature and mass, and can be different, so im trying to measure a variable unit with another variable unit.
Im just saying it because i like to make your time harder.

Time, mass, and distance are not relative. There are specfic definitions of each. There are six base units which have definitions, everything else is derived.

Just to throw out there I picked up a new psu. I happen to sell few parts i had laying around. So seasonic has 15% off I picked up the 620 watt psu they have. I think that should take care of it for me and not overkill.
