From the article you linked:
"Above, a chart of relative power consumption. Again the Wattage shown is the card with the GPU(s) stressed 100%, showing only the peak GPU power draw, not the power consumption of the entire PC and not the average gaming power consumption.
.
Yeah and? I've already compensated for that.
The 2 cards by themselves are 500w's, add a highly OC'd CPU, tons of fans, OC's on the GPU's, drives and you are way over the amount a 850w can take.
.
Wow you cannot read at all. SLI 780's pulls 440w at peak 100% load, and that still doesn't compensate for PSU efficiency so the draw at the actual PSU is still closer to 400w....just for the cards.
I've already stated that your ''highly overclocked CPU'' would be drawing 100w while gaming most likely. It may draw 200w with just the CPU stressed at 100%, but no game or bench would ever stress it that high at the same time the GPU's were being stressed.
I also do alot of benchmarking as a hobby and the cards are always maxed 100% in the test's. To not compensate for full load is just plain stupid.
.
lol a lot of benching with an I7 920, sure. My left pinky has done more benching than you have. But anyway, as stated the 860w psu would have plenty compensated for even full load of everything, which would never happen.
Even if you stressed the GPU's and CPU's to 100% at the same time, thats 600 even call it 650w. Add 50w to run the motherboard, so you're at 700w on the 12v rail. Add even a ridiculous 100w for overclocking and thats 800w, not a problem at all for the 860w PSU.
So you cry bloody murder when you think I am stating something incorrect and when I prove the statement wrong you say "whatever"... Also that comparison was of a very, very efficient 860w PSU. If I compared it to the 850w you think I should get that margin would be much greater. All I was debunking was the statement that a 1200w PSU was less efficient then a 860w.
.
What are you talking about? I didn't say whatever, my point was the difference was so minuscule it was ridiculous for you to even say your reasoning for getting the bigger PSU. Do you really think you were proved right? 1% difference of efficiency putting 800w of load on the 860w PSU VS the 1200w unit. wow.
Even if the PSU was 85% efficient, that would probably add up about $20 a year of electric, and that is definitely a bloated figure if anything. That would STILL take you 10 years to make up for the cost difference.
I am done talking to you, I have already wasted too much of my time. .
I wish that was true, you just keep digging yourself into a deeper hole. The more you say, the more you get proved wrong. lol
