Is 400 watts enough for this?

I'm not sure I really trust all those power supply calculators out there. So I figured its best to ask a real human who will have the knowledge and experience. My system will be as follows:

I5-3450

Spare dell motherboard

GTX 750 TI

8Gb of DDR3 1600 mhz

Creative Xfi sound card

DVD drive

CPU fan

Samsung 850 Evo SSD (500 Gb)

Seagate 1Tb storage drive

System exhaust fan

And a few USB peripherals like mouse, keyboard, flash drives, xbox controller... stuff like that. Is a 400 watt Power supply good enough for all this?

Really depends on which 400 watt you are talking about as many of them are not very good so what exact brand and model are you talking about?
As for the calculators they are all rubbish that will overstate numbers by 28% or more

Might touch 150W from the wall if you try to kill it with a power virus.

Thats a model from 2008 and its a rebrand of the Seasonic S12II and while its not terrible i do question how much of those 400 watts it has lost
By the way the 12v rail is only rated for 360 watts so its not a even a 400 watt unit the other 40 watts are on the other rails

Well its not perfection but it does sound like its more than plenty, as other members have said.
