How accurate is the estimated wattage?

I'm making a new build for gaming and some 3D design for school. The estimated wattage is 461W, so I was looking at a 550W power supply, but some people say that I should get at least 650W.

So basically, I'm wondering how accurate is the estimated wattage? Here's a link to my build: http://pcpartpicker.com/p/2DVCHx I'd also appreciate general thoughts about the build, it's not my first one, but it is my first time using this site.

Thanks in advance!

Don't buy that SSD. A good 550 watt psu would be enough for this build.

Thanks! I'm actually still on the fence about do I really even need an SSD, the only thing I'd really put there would be the OS, so it's not something I see as necessary.

Do you need one? No. Is it very nice to have? Yes.

Kingston did a bait-and-switch with that SSD. Don't get that one.

Ehh, take the estimated wattage, add 50%, the you have your psu good wattage

Minimum x 1.5 = optimum, roughly, the bigger the minimum, the smaller the number after the decimal point should be, might need to calculate that.

461 x 1.5 = 691. So a 550 would be enough, but if you want overclocking and lots of headroom, i would get a 700 if you can afford without filing for bankrupcy.

550W should be enough.

About the SSD, the V300 series is pretty bad. It's overpriced to say the least, and Kingston changed their NAND flash type so now it's a slightly faster and a bit more reliable HDD. When the space begins to fill up to about 100GB, it'll probably become even more slow and maybe even slower than a 7200RPM mechanical drive.

If you can afford one, I'd definitely get a Samsung 850EVO 250GB SSD. (Or a 120GB)

I'd suggest a 600W or 650W, G2 EVGA 650W would be perfect.
