Thanks for the throught description.
Well Ibelieve in my case it's different coz I got a 1000W PSU and have a little gadget (a fan controller) that also shows the energy consumed. These days never goes above 400. Even when I had my graphics cards working properly which now I have 1 out of 4 only (see my other post 2 x EVGA 9800gx2 are tehy dead? ) barely went above 600.
So I think it gets enough power.
Looks like that my home built computer is like Real Madrid. Excellent and expensive players, but as a team is sh!t
(Or maybe just expensive players in my case)
No offense if you are a Real fan.
Please help with that one too if you can.
