I'm really cautious when it comes to even considering something like a 750-800 Watt PSU, reason being is I automatically assume that's how much power it's going to draw and I'm going to watch the electric bill go through the roof! I realize that's how much the PSU is rated for and most CPUs don't draw that much power, I also know that you can adjust how power a CPU uses. What about when you are playing very demanding games on high settings? Is it possible that you could use the whole 750 Watts and if so for how long, is their some way to know for sure? Should I consider going with a less powerful PSU? Thanks for any info.

Based on some of the math here:

http://www.overclockers.com/how-much-does-it-cost-to-run-your-pc/

If you got to full load on a 800 Watt PSU 24/7, it would run you....

$69.12!

You will never hit that cap though, so if <$69.12~ is not a huge deal, you'll be fine!

Hi..as per the datasheet that you have referenced, the absolute maximum rating of Vcc is 35 V. You can exceed that at your peril. Never operate at the absolute maximum rating. All test conditions in the datasheet indicate a 30 V maximum, that is probably a good maximum operating point for long term reliability. Those dots are for reference when using coupled inductors. If the 2 inductors are coupled, then the polarity dots should be observed. If not coupled then it does not matter. prototype pcb assembly services
