Help needed

Can someone tell me how much power does a 1.25gb nvidia geforce gtx 570 uses? because when i click proceed it says it only needs a 600w power supply but when i click on the question mark next to the graphics card option when im designing my pc it says it needs a minimum of 650w :S

 

[Nemesis]

Next to that the maximum power usage is noted and it is 225W

 

[zamulak]

so does that mean that i only need a 600w power supply then? what about the minimum psu then :S

 

[Nemesis]

Id say that its just playing safe....
Its always good to overspec PSUs even if your not planning on upgrading much

What is your current spec??

[Fear]

right i have just done the spec you have above and selected a underpowered PSU just to get the figures.

1.We notice that you have selected a 450W power supply, but based on our calculations we recommend you change your selection to a 600W power supply because your computer could require up to 552W of power including a 20% allowance.

so you will be ok with the 600W PSU

as nemesis said if you want to future proof just incase you ever get a higher powered graphics card or add to the system i would up it to the 650W

also if you can spend a bit more i would get the caviar black HDD (forget that the mother board only goes up to 3GB/s)

 

[Nemesis]

Like Fear said i would upgrade the First HDD to a caviar black for quicker boot times and program loads.
And maybe a caviar green as your secondary (not so important)

 

[Fear]

sorry nemesis i didn't notice straight away but motherboard only supports 3GB/s so it's a waste of the caviars 6GB/s but i also just remembered that it will boost the cache from 16MB to 64MB so it will still be better.

 

[Nemesis]

Yeh and im pretty sure that the caviar drives dont make use of even half of the speeds offered by sata 6gb/s

In fact i dont think there are any mechanical drives that benefit greatly from SATA 6gb/s as they just dont reach those speeds
