Hello, I wanted to know if this power supply would be good for my needs.

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

I don't think i need this much power but I would like extra in case I ever did sli/crossfire. I have an overclocked i5 750 @ 4 ghz and a ssd, 1 7500 harddrive, 1 dvd/writer and a 7970 overclocked and about 7 fans(3 200, 2 140s, 2 120s). I will be upgrading this system once ivy bridge comes out.

The only one that comes close is the Kingwin Lazer Platinum LZP-850 but it's only $10 cheaper.

I would personally consider sticking with the Ultra unless I was having stability issues. It is definitely not a top tier PSU, but if it works then why spend the extra money on another PSU. If you really want to upgrade your PSU, then a good quality 750W is more than enough to power your rig. Something like this Rosewill Capstone 750W http://www.newegg.com/Product/Product.aspx?Item=N82E168...

For a system using two Radeon HD 7970 graphics cards in 2-way CrossFireX mode AMD specifies a minimum of an 750 Watt or greater power supply. The power supply should also have a combined +12 Volt continuous current rating of 59 Amps or greater and have at least two 6-pin and two 8-pin PCI Express supplementary power connectors.

Seasonic 850 Watt power supplies have a +12 Volt continuous current rating of 70 Amps and also have at least four PCI Express supplementary power connectors so it should be sufficient.

thank you. I couldn't find any power supply guides on the internet for the 7900 series so i had to go by the reviews.
