System won't stay up after installing NvidaGTX560Ti

[bbd33]

Hello,
My original hope was for multi-monitor support from a single graphics card.(Integrated mobo graphics leave much to be desired.) Upgraded from 250W stock psu to 600W to aid the card,(32A on the 12volt),but keeps shutting down after power-up. Does it need more power?
Windows 7 Home Premium 64bit.
Intel Core i3-550
6G DDR3
MS-7613 (iona gl8e) ver1.1
Advice please for dual digital monitor set up, non-gaming,HD Video and audio a must...(2 Acer 24in. LCD)
Thanks in advance.

That PSU should be enough. What make and model?

Yeah that setup isn't bad at all, my guess is that the power supply has something wrong with it, it could be that the cords for the graphics card are defective or some internal issue with the rail. Please give us your power supplies specs to be certain.
