Rocketfish PSUs are actually pretty solid on average, though they like to rate units at their maximum capability rather than what the manufacturer recommends.

Also, 50-100W is a safety margin. 300W is stupidity.

I'm currently running my 2 560ti OC to 900/2100 (mild) on a 650TX so far it's running solid.

2600k @ 4.5ghz
2 SSDs - raid 0 + 1TB WD green in a HAF 932 case

So an answer for your question is "plenty".

The 850 will laugh at that and then ask for more.

You could probably run 2 580s in that system and be okay (hint the word probably)

From what I see, the entire system pulled 450W from the wall. That means about ~400W DC if the PSU is good and averages 85-87% efficiency. So 1kW is enough for two entire system with leftovers.
