So..... I picked up a Belkin Conserve Insight (http://www.belkin.com/conserve/insight/). It's like the Kill-A-Watt and equipped with a 2-3 foot cable so you can put the hand meter on your desk or mount it. I picked it up for $29.99 at Fry's Electronics. My original plan was to pick up a Kill-A-Watt, until the extension cable on the Belkin sold me. If you don't have a Fry's you can buy it online from a lot of places or get it at your local Staples or Walmart.

So why am I doing this? Well mostly because everyone screams about how much power the FX-8150 consumes. I've seen many review sites show major power consumption readings. However, I wanted to see for myself and share with OCN my personal findings.
Side note: Ultimately I feel I'm sort re-posting the review site readings somewhat. Ha!

What did I change? I only changed the multiplier, Bus, and CPU voltage. My video cards aren't and weren't overclocked for this. All of my fans were at their max RPMS and my H80 was on setting three or high performance.
EDIT: 02-18-2012: So I couldn't resist. I overclocked my video cards a bit. Check for the BF3 photos below.

The other stuff? I couldn't think of an easier way to provide proof of use other than the photos listed below. If you need more proof or a video let me know. Keep in the mind the watts fluctuate so I tried to take the highest reading than the lower reading. If you would like to see the low readings let me know. OH! Yes.. only my tower is and was plugged into the meter.

My system specs are listed below in detail in my sig but in short.....

CPU: AMD 8150
GPU1: GTX570
GPU2: GTX570
RAM Stick: 2
Hard Drive 1
SSD: 1
DVD Drive: 1
Case Fans(H80 Fans included): 6
Cathode Lights: 2
Water Cooler(H80): 1
Fan Controller: 1
Sound Card: 1
PSU: Corsair AX750

So.... take this meter with a grain of salt. Take my results the same way. But if the readings are true, I'm spending anywhere from $19-53 a month to run a stock or overclocked machine. I enjoyed doing this and if you have any questions or requests let me know. Thanks and enjoy.

I said I didn't overclock my video cards but I just had to do it! Why not? Got BF3 Test?

very nice review...but
jumping from 280w to 500w is tooo much

Its alot indeed. Phenom II is also quite bad in this regard, both Thuban and Deneb produce similar readings at their respective "max" clocks. Nehalem was similar also.

It's really Sandy Bridge that makes this look so bad. Intel did an amazing job on it and raised (or lowered) the bar.

Ya can't wait. I hear the end of the year and it's an 8350? It was something from Wiki so take it with a grain of salt.

I couldn't resist. I added BF3 photos with OC'd cards and one Folding photo @ 4.8ghz. Enjoy.

Still under 750watts. This is kind of a good basis for proving sometimes you don't need a 1000w+ PSU.

Thanks again for the update. Really good info here and a perfect real world reflection with the 570 sli / oc'ed power consumption results.

Don't forget the efficiency of a good PSU as well, so that wall number isn't 100% representative.

Also thats at the wall, Work out what efficiency your PSU is and then calculate what the components are using.
And enable Cool & quite, That should drop the idle power usage down to 120ish W (well it did for me with my 2 GFX cards from 179W)

Power company only cares about power draw at the outlet. Didn't Cool & Quiet hinders the performance (one of the flaw in early FX benchmark)?

It's more a headroom thing than an extra 5 bucks a month. It's nice knowing he could probably get by with a very good 650W PSU even overclocked given the PSU's efficiency.

While yes you are charged by draw at the outlet but the power ratings of the PSUs are what it can put out into the computer. So 750W draw at the outlet at 80% efficiency means that PSU is actually only putting out 600W which means much more to go

. For you to maximize 750W output you should be drawing 937.5W from the wall assuming 80% efficiency but I would not recommend running your PSU at 100%.

That is very true. Assuming at the outlet draws 600 W, an average efficiency (0.85) estimates an internal power draw of 510 W.

I'm one of those picky guy, extra $5 per month = $60 per year. In California it is more like $120 per year.

I've said it before in other posts, I love this chip, but damn it soaks the power. Here is mine at idle with C1E enabled and then full load JUST cpu, no video under prime. I break 730 watts with full load CPU and GPU's
Chip at 5.0Ghz, 1.56V This chip is pulling more then 420 watts alone under full load.

With only 5770's ?
