In the process of my first build here, but I'm stuck on a power supply for my first build. I don't want to spend money on a high wattage PSU I won't fully utilize, but at the same time I definitely don't want to buy a cheap one that will fry. My specs are: - AMD Phenom II X4 955 3.2 ghz Black edition. - HD 6850 (Would brand play a significant role in Power consumption for the PSU?) - Gigabyte GA-890GPA-UD3H - Corsair 2x2 4gb DDR3 memory 1333mhz - Western Digital 500GB HDD - Coolermaster Gladiator 600 Chasis - Samsung DVD writer.
