How many fans? That will make a difference. Also, I'm surprised you're going with such a basic hard drive given the rest of the system specs.
At any rate, 750W should be enough, but quality is the most important aspect here. A cheap power supply in a high-end system like this is a huge risk to take. What kind of chassis are you getting? Make sure it is a good chassis, because a poorly-vented chassis will lead to heat issues, which will also kill your system. A quick search led me to the following chassis/psu combo on Newegg: http://www.newegg.com/Product/Produc...82E16811129021 Click the View All link under the combo deals and here is a 850W PSU option there that will save you a few bucks. It may be a little more than you wanted to spend, so do your own search. But stick with Antec if you can for the PSU. And don't overlook the necessity of a well-designed chassis for a performance system like you are building. |

I like to think more is better; 500-650watts is plenty. There are 550w units out there as well. Remember your system only takes what it uses, so your video card will pull about the same as your X4 9750 during internet play 36watts. And more than the CPU during screensaver and game play. 200watts-500watts usage.

Usually I just wouldn't respond (read the thread I linked!) but a 850W Antec? Are you kidding me?
Minus the fact that the build is a very weird mishmash of parts, a 500W Earthwatts, 400W Corsair, or 400W Seasonic is very much fine. A low-quality "high-wattage" power supply just costs you more in power bills and is prone to failure. For $150 you could get a modular Corsair 520, not some junk non-Earthwatts quad-rail Antec bundled with a giant black box with no features.
