overclocking 960t problem - psu???

[jwmachon]

Hi,

This is my system specs

AMD x4 960T 3.0Ghz Processor
Hyper 212 evo cooler
GTX 560 TI GPU
Windows 7 Ultimate
various usb sources keyboard mouse, 360 controller, joystick
pci Wireless card
EZCOOL 650W Power supply

Here is my problem

Overclocking the cpu upto 3.4ghz is not a problem on stress tests however if i go higer or increase the voltage a bit the pc shuts down completely just turns of no screens or anything when i click start to stress test

Core temps are fine

Does this sound like a psu not good enough

Thanks

Jonny
