Hello, I've been trying out my new GPU (Gtx590) for a week now with dissapointing performance, last night I tried the newest Nvidia drivers and tried playing Mafia 2 once I've play 10-20 min the computer just died, like pulling the power cable. And now refuses to start, I've tried if the PSU work in another computer without any luck and was thinking of what PSU I should get next?

GPU: GTX590 (stock)
CPU: AMD 1090T (currently stock, might overclock)
RAM: 8gb 1333Mhz (stock)
HDD: 1.5 TB

PSU which broke: Corsair CX600
Output: +3.3V@25A, +5V@25A, +12V@46A, -12V@0.8A, +5VSB@3.0A

And I was thinking of the CX750M
Output: +3.3V@25A, +5V@25A, +12V@62A, -12V@0.8A, +5VSB@3.0A

And could the CX600 be the reason why my 590 were underperforming?
 
For a system using a single GeForce GTX 590 graphics card NVIDIA specifies a minimum of a 700 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 50 Amps or greater and that has at least two 8-pin PCI Express supplementary power connectors.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Total Combined Continuous Power/Current Available on the +12V Rail(s) rated at 45°C - 50°C ambient temperature, is the most important factor.

Overclocking of the CPU and/or GPU(s) may require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.

I can see why that CX600 died. Over-stressing a PSU means it'll have a much shorter life span.

The CX Series also uses cheaper lower temperature spec'd components in its build.

I agree with the other posters in this thread, get a better quality PSU.
 


The 80 PLUS Bronze unit will work. It is less efficient than the 80 PLUS Gold unit so it'll just give off more heat.
