Re: 300W with GF 6600
Frankly Watts are nothing. There are 500 W psu out there with 60% efficiency and 12A on the 12V rail.
Which would get Killed by A good Antec 330 truepower,
If yours has 18A, you're fine buddy.

Mild agnosticism —the view that the existence or nonexistence of God or gods is currently unknown but is not necessarily unknowable, therefore one will withhold judgment until/if more evidence is available. A weak agnostic would say "I don't know, but maybe you do."
