1000w Overkill?

Below is a list of the components I intend to put into my first build. I really can't determine if I'm overdoing it on the PSU and I'm assuming, the higher the Watts the better, just to be safe. I also can't determine if this is even a good brand so some advice would be appreciated. I don't want to spend over 150.00 on a PSU.

Also could anyone advise me on the graphics cards? Would it be better to get one higher rated card or SLI two of those GTX 550 Ti's? I don't want to spend more than 250.00

1,000 watts is definitely overkill.

Have you checked the Nvidia web site? Nividia recommends a 525 watt power supply with two 6-pin power cables for a desktop gaming rig with two GTX 550 Ti cards in SLI mode.

Overkill much! But they way I see it, a 1000W PSU can last to system to system as long as its a decent brand. If you want to do 680 sli or 7970 crossfire, then a 1000watt will hold up, and be cheaper in the long run since you wont be in a need for a new PSU.

Depends how you look at it tho. But a 600watt would be enough and then some.

1000w Is extremely overkill for your current build but would also give you alot of headroom for upgrades of your video card .. It would also hold up much longer and is a lot of wattage so you wont have to upgrade anytime soon

For a system using two GeForce GTX 550 Ti graphics cards in 2-way SLI mode NVIDIA specifies a minimum of a 500 Watt or greater power supply that has a combined +12 Volt continuous current rating of 38 Amps or greater and that has at least two 6-pin PCI Express supplementary power connectors.

I wouldn't call it overkill, but you definitely have much more than you need. Unless you plan on adding more parts in the future, 700-750w seems about right.
