Newegg power calculator wrong?

[patater]

Hello all you TH peeps!

So, I was doing what I do best, being bored and throwing ridiculous gaming PC builds on newegg that will NEVER happen (hahaha, dream machines if you will) and thought of a very good question...will the power supply be enough?

First my list:
5820k
ASUS Rampage Exreme V
G.Skill 4x4gb DDR4 PC 3200
ASUS Strix GTX 970 (SLI)
8 x MX100 256GB SSD
2720SGL raid card

I seen a decent seasonic 860W platinum rated PSU. Thought, would this work?

Found the tool on Newegg to calculate PSU recommended wattage. Guess what it came up with? Said this PC would need at least 1350W to run! That is crazy!

I know, I'm the only sucker who puts together dream PC's to never buy them. But, it would be ONE HELL OF A BUILD if someone had the money for this! Im sure some of you people reading actually have something very similar! Would hate to see you power bill, but LOVE to see your FPS!!

Each component has a portion of system overhead, and allowance made is made for crappy PSUs that deliver 80% (or less) of what they promise and to allow for degraded performance at higher temperatures. Some PSU's rated wattage is only 30C which is cooler than a summer day here. At the real temperatures inside computers, which may have inefficient cooling, their power drops like a cartoon safe.
