My build: http://pcpartpicker.com/p/nzn2jX
I put my build in several different wattage calculators and got completely different results. These are the results, along with the PCPP estimated wattage:
- 503W -- PCPartPicker Estimated Wattage
- 800W -- ASUS Wattage Calculator (minimun) (http://support.asus.com/powersupply.aspx)
- 1197W -- Newegg Wattage Calculator (http://images10.newegg.com/BizIntell/tool/psucalc/index.html?name=Power-Supply-Wattage-Calculator)
- 472W -- MSI Wattage Calculator (http://us.msi.com/power-supply-calculator/)
And the popular PSU calculator at www.extreme.outervision.com/psucalculatorlite.jsp doesn't work. The page doesn't load for me.
I don't understand why the results above are so different. What size PSU do I need? Thanks.
