I have a XFR XTR 550w, but I want to upgrade to something with more headroom. Thinking something around 750w. Any recommendations??
My Silverstone Platinum 1500w that powers my 3770k, GTX 680 and 3 hard drives would like to pick a bone with you.
Here's the deal:compared to what?
Did you even try the calculator? Hint it doesn't say anything near the 850w, try 1/4 of that.Here's the deal:
The values that are used in the calculations are based solely on their peak power draw and their TDP. However, today's components output far more heat than their old-generation forebears per watt consumed. As a result, the recommended minimum wattage as indicated by such a calculator would have been far higher than what those components really draw. (Anyone really need an 850W PSU for a cheap dual-core CPU with only integrated IGP?)

That calculator and at least 1 other seems to be accurate. Now Newegg calculator is drunk
I haven't used PSU calculators recently but historically they have been inaccurate. The inaccuracy varies depending on component selection. Getting power draw numbers from tech review sites and adding them up yourself is more accurate.
