those 3 gpus run at max with power supply.

Yep over clocked and 24/7 stable.

And wattage this system consume?

looks like an accident waiting to happen

Just looks dodgy with all the cables.
790 watts I believe it drew last time I checked.

Hope that radiator ain't on!, seriously get all that gear fixed down into some sort bench if you want an open air system, an ikea table doesn't do it for me.

most people in your "situation" would use a milk crate or something.

Somehow your benchmarks look not right. SHA1 is too low comparing to WPA/WPA2 which is a bit too high :/ also your PSU run on +-MAX load, it's also not right, you have to be on ~80% load to be safe.

My system must be majestic then. Can someone who knows a lot about power supplies pitch in, as out of the 790watts I've measured, 20% of that will be waste then, so my computer is actually using around 650watts.
No idea about SHA1 , I just used the benchmark tools for that.
For WPA I get 160k each for my 7970's and my 7850 does 95k. They are overclocked.
