You included tdp but tdp /= actual electrical power. Intel approximates it from base clock (practically all consumer motherboards ignore the tdp/boost spec). AMD uses voodoo to calculate tdp, it's a pure marketing number with no basis in power usage. To make matters worse, motherboards typically go nuts with voltage on consumer boards, and power draw can vary wildly depending on what instructions you're using. There are a crap load of x86-64 extensions.
Yes, you forgot ram. And network chips, motherboard power delivery losses, motherboard power usage, cabling losses, etc. I'd guess it would total 50-100w, but feel free to current clamp the psu rails to get a realistic number.
As for the 95% uptime, I agree with you. I wasn't considering how much breathing room that actually provides, I was just going with my instincts.
