The PCPP PSU calculator sounds like a great feature on paper, but it really isn't that accurate and doesn't help that much at all. In reality, it causes more confusion than good.

How accurate is the Power Supply Calculator?
While highly accurate, it's recommended to add a 10-20% buffer to the calculated wattage for safety and future upgrades. For best results, input as much detail as possible, but the PSU calculator tool can estimate based on common setups if specifics aren't known. After calculating your needs, Newegg’s power supply calculator will suggest compatible power supplies, but the final choice depends on your preferences and requirements.

So far, the most realistic PSU calculator I've found is this one: http://www.extreme.outervision.com/psucalculatorlite.jsp · It has much more reasonable sounding estimates (it recommends 550W minimum for an R9 290+4790K instead of somewhere in the neighborhood of 400W-450W like the PCPP one does), and has systems to compensate for things like overclocking and capacitor aging. ...
