Hey Pum,
The X1950 is a seriously power hungry beast!
That corsair may not be up to the job of handling it well im afriad!
(and please no people jumping in telling me that they are running their 8800 cards off it fine as they do not have the same power requirements as these older cards do)
I know you think you have 40a in that power supply, but the reality is that you do not.
A multirailled unit will only supply a maxmimum of 18A per rail... this does not mean that if you have 2 rails it will supply 36A etc...
What this means, is that each rail has a limiter on it that wont allow it to exceed that amount.
I perviously had a sapphire X1950 pro... I had it on a 350W dell psu... which wouldnt even boot it up... anyways I did a lot of research on this an it was all about power.
I upgraded to an OCZ GameXstream 600W and it ran fine though I had crashes like you experiencing in the beginning.
It needed 2 molex power connectors and I plugged two in from the same rail at first. This is silly as that rail has a max of only 18A and the card needs a rail of minimum 30A.
After plugging these in from each seperate rail I was able to run perfectly stable.
Also a good power supply will run the card cooler!
try plugging in a molex from each of your two unused rails to the card... this will give it the most even power.... you say you have 3 rails... try and use the rails that do not have other peripherals plugged into it.
I have now stopped messing around and bought an Enermax Galaxy 1000W and what can I say! perfect
