How much power do you need???

[Jeff_s510]

so i figured id post this thread to help people descide how much they realy need. i would like anyone who knows the exact power draw from there system to just post some system specs and your power draw! my purpose of doing this is just to show people you dont need a 1200 watt psu for a single I5 with 1 video card. also to give people an idea on the "will 450 watts be enough?" question

so for me:
I5 2500K @4.5Ghz
GTX 560Ti
4 corsair AF fans
1.5TB WD Black drive
OCZ Revo drive3
16gb ram

Power draw (from corsair link) 305 watts

That's a good value, The latest gen Intels are more energy efficient than ever. My system, although not as powerful as yours, probably draws more. I don't know how acurate your value is, but it's a good one.
I saw an i3 once sucking about 22-23W from the wall at idle and 48W in full load, so I agree with you that some people might go over the top with 850-1200W PSU's when they really need 3 times less power... maybe even less.

Here's a good vid to help people make an idea about power consumption.
