Please help me on choosing a correct power supply for my system.
My spec like below:
- Pentium 4 3.0GHz
- Motherboard 775VM800
- 2GB DDR RAM (1GB + 1GB)
- 320GB Harddisk (160GB + 160GB)
- TV Tuner
- 512MB DDR2 Graphic Card

How much watts my system need?
Is it 350W,400W,450W or 500W?
Or you have another suggestion?

Best solution
