It can. When it can't output enough watts to the card, it will shut down your system to prevent damage. Maybe in your case the Thermaltake PSU is a good one but it can barely hold up, it is probably not providing enough power for the card to perform to the fullest. Can you elaborate more on this "lag"?

I just looked at your sig again. The Phenom 925 OC'ed shouldn't be a bottleneck. Most likely the PSU.

Graphics cards need power to run. When you are gaming you will need more power because it has to do more things such as render textures and stuff. When the needed power isn't there then the card cannot do it's thing, performance will drop. This is what you are experiencing right now.
EDIT: By the way, what exactly do you mean by chocked?

For a system using a single GeForce GTX 470 graphics card NVIDIA specifies a minimum of a 550 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 38 Amps or greater and that has at least two 6-pin PCI Express supplementary power connectors.

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

Overclocking of the CPU and/or GPU(s) will 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.

If you have the Thermaltake SMART 430W (SP-430P) it has a maximum combined +12 Volt continuous current rating of 34 Amps and with one (6+2)-pin PCI Express supplementary power connector, and is insufficient to power your system configuration with a single GeForce GTX 470 graphics card. This is the only Thermaltake 430W PSU model that may have had a possibility of working, although you would need to use a dual 4-pin Molex peripheral to 6-pin PCI-E adapter cable.

If you have any other Thermaltake 430W model it will be grossly insufficient to power a system with a GeForce GTX 470.

It's not worth risking the possible destruction of any of your system components.
