i was wondering what i need for my system because it keeps crashing.

I have a msi NF750-G55 motherbord.

Two xfx gforce 9600gt sli.

Amd Phenom II x3 at 2.8 GHz

My psu is one that came in the case its ATX 450W psu.

My cpu fan is TR2 r1 tt from thermaltake.

I didn't know what i needed for it exactly and if water cooling would be unnessary. I don't have much extra cash so if i can keep it under 200 would be nice.

I would say a new PSU

A single GeForce 9600 GT requires you to have a 450 Watt power supply unit at minimum if you use it in a high-end system. That power supply needs to have (in total) at least 26 Amps available on the 12 volts rails.
A second GeForce 9600 GT installed on this system requires you to have a 500 Watt power supply unit at minimum if you use it in a high-end system. That power supply needs to have (in total) at least 36 Amps available on the 12 volts rails.


There are many good PSU's out there, please do have a look at our many PSU reviews as we have loads of recommended PSU's for you to check out in there. What would happen if your PSU can't cope with the load?:

bad 3D performance
crashing games
spontaneous reset or imminent shutdown of the PC
freezes during gameplay
PSU overload can cause it to break down
