Power Calculator ?

Hi All

Some where i have seen a site where you can chuck all your components in and it tells you the Watts Drawn, what is it lol ? I just wanna work out if i can go Sli with some head room left

Most sites tend to show recommended wattage PSU to use, one being below:

Looking at actual power draw your best bet is to look at review sites as these often show total power draw from the socket.

cheers mate @ 100% load my system in SLI 825w according to that site :eek:

SLI'd GTX 480s- because the radiators in your house just aren't hot enough.

is it just my imagination or does these sorts on online calculators really over-compensate?

i understand why they do it though:
- people dont get underpowered psu's and blame problems on their calculator
- they might be back-handed by psu companies

i personally think they do indeed over calculate but its better to over than under, i would be worried if my system with another 480 pulled 750w all day lol

i think they should give two values

1) actual power requirement - no bias, just the real value

2) rounded up safe value

e.g.

1) your system should draw ~230W

2) we suggest a 250/300W
