Hi! I am trying to compare my old pc power draw with a pc I am looking to buy next month. After trying a while to compare on my own, I got lost, mainly because old components info are hard to find around the web and I don't have experience with this so i came here.
I haven't overclocked the old pc and I won't overclock the new one either.

OLD (bought in 2009):
AMD Phenom x3 8750 (2,4 GHz, triple core)
Sapphire HD 4850 (512mb, 256bit. ddr3)
Western digital blue 320gb
2x Kingmax 1GB DDR2 @ 1066mhz
Motherboard AsRock A770DE
PSU is spire 420 (no certificate)

What I am looking to buy is:
AMD FX8350
Sapphire HD7950
Western digital blue 1Tb
1x Corsair DDR3 8192MB 1600MHz CL10 Vengeance
Motherboard ASUS M5A97 LE R2.0
PSU COrsair CX600M (80 plus)

In my situation, power consumption matters. I know the new components have lower power consumption in idle. I am mostly interested in a peak comparison and if possible a medium comparison (watching a HD movie for example). Thank you!

ok... your origional build under full load assuming a bit of an overclock would draw something like...

Phx3 8750 - 220W
HD4850 - 130W
rest of system ~ 50W
= 400W

future build (assuming overclocks)
FX8350 - 230W
HD 7950 - 200W
rest of system ~ 50W
=480W

now understand this is under 100% load with overclocks assumed... the actual W will probably be a bit less (maybe as much as 80W less) without overclocks. Furthermore i can't suggest in strong enough terms that the m5a97 LE R2.0 is not good enough to run a 125W cpu. And it's certainly not good enough if you plan to overclock. I suggest you get the m5a97 R2.0 or ga-970a-ud3 as the "cheapest" boards for that monstrous cpu.

additionally, AMD cpus are notoriously unstable with...

additionally, AMD cpus are notoriously unstable with just 1 stick of ram. please get a 2 stick kit.

Thank you for the clear and useful info. The Motherboard on my wishlist is actually the EVO version. I was going to buy a 2nd stick of ram (same as the one mentioned) in less than 2 months after purchase. Maybe you would like to take a look at the wishlist. It's not english website but the components have same english names and details are predictable. Components here are more expensive in my country than the rest of EU (some PC cases for example costs twice more). The current build is ~1100$
