hey all - i got a biostar TA870+ and AMD Phenom II x6 1055T - A COOLERMASTER MID Tower case - a 2x 1gb ram - 300 watt - my question is do i have enough power ??

More than enough, since you have no pesky video card or hard drive to burn all that extra electricity.

You only need 181 watts, according to this power supply calculator.

Unless it's a crappy PSU that can't actually deliver near what it claims. Be easier to help if you listed all specs, manufacturer and model #. Links help, too.
