Re: Power Supply Question...
As long as it isn't something like the x-fi pro, you should be fine. However, running a psu at 90% of its maximum power constantly is not a good thing. In the long, you might want to, because that's a power-demanding system there. A 500W+ would do you even better, but if you don't do any overclocking, etc. you shouldn't be having to worry about a melt-down...
Macbook Pro and Logitech z5500s. All you really need.
