Overloaded PSU or Graphics card fault???

I have just installed a new geforce 6600 256 MB RAM AGP graphics card. The graphics are quite poor, frame rates are slower and image quality is poorer than the fx5500 it has replaced. I cannot decide if this is a problem with the card ( it has a fan and requires adittional connection to the PSU ) or the power supply. I have a 300watt PSU which is possibly not up to the task. I would have expected system instability as opposed to poor graphics performance if the PSU was over-burdened. Any thoughts would be really appreciated.

About nine months ago I installed a basic GeForceFX 5200 nVidia chipset graphics card and found out, after reading the manual, that it needed at least a 300w PSU and preferably 350w.

At the time my six-year-old Enermax PSU was delivering not 235w as I thought, but just 100w...:-(

It coped, as a quality unit will do, with the demands placed on it, but I took the obvious step.

It looks therefore, especially as you have a TV card as in my case, that a more powerful PSU is required - I had to buy a 500w unit...:-)

300W is low for that spec. Have a look here for an estimate of your computer's power needs click here
