anyway guys all i want to know at this point on what power source i need to beable to run the card and the new cpu with out me having to empty my pockets in to a device i'll never use to its full potential so really i just want a good power source that matches the old one enough where it is easy to install
Looks like a 400-500W range PSU will be fine for you.
Check ones you are interested in here: [to avoid fraudulent 80 Plus claims]

I checked my own, and even at lower watts it's waste (as heat) is still reasonable.
I would pick this one for you with a little extra room:

They didn't have a 500W.... 80 Plus Gold rated, and very quiet, good deal.

Here's a look at the power consumption of the GTX 550 Ti:
GeForce GTX 550 Ti review MSI Cyclone II OC - Power consumption
With one GTX 550 Ti under load in their power-hungry system (take note of what's in their system!), their PSU pulled 289W from the wall outlet. Their CPU was idling, so I have to add 65W for the E4500 or the E7500. So with the 550 Ti and the E7500 (or E4500) both under full load, the PSU would then be pulling 354W from the wall outlet. This means that if the PSU is 90% efficient, then the computer is pulling 318W from the PSU. Your gaming power draw will be even lower at about 200-275W, maybe as much as 300W for some games. Then you have to remember that these calculations are based on their power-hungry system, so we can easily knock off another 25-50W.
If you were to use a CPU that can pull up to 125W while under full load (such as a modern AMD CPU), then the final calculation would be 372W absolute max in extreme situations (unrealistic situations), and about 275 -350W while gaming. Again though, knock off about 25-50W because these calculations are based on Guru3D's power-hungry system. So really, it would be about 225-300W at the most while gaming with a more powerful CPU like yours.
The two 450W PSUs I recommended are able to easily deliver 450W 24/7 up to an internal PSU temperature of 50°C. Therefore, these PSUs would have absolutely no problems with that and the average efficiency would be better than it would be if a 'bigger' PSU were used.
Being that these are modular PSUs, installation should be a breeze.
alright, i am giving that one an order if any one else has anything else better to suggest then tell me other then that i have it about ordered and all i need to do is hit the accept button
The thing is, what about the E7500? Or are you going to just take the PSU and the video card and make a new system out of it someday?
Oh, I see now. That's a good idea. There's no greater computer-related pleasure than building a computer and then using it. I also love upgrading because the only real obstacle is money. With a pre-built, there are other obstacles.
Do you know if you'll ever have more than one video card?
maybe idk if i'll do sli or just have one really powerful gpu
i may do sli just because the card i bought is ready for it
In that case, you would want a good 550W PSU to power a system that has two 550 Ti's in it. A high-end 450W might be enough while gaming, but I wouldn't want to chance it. It's not that anything bad would happen (especially not with a good PSU), but it's just that it would be better to have enough power.
I'm a little short on time at the moment, but one PSU I know I can recommend is the 550W SeaSonic G Series. It's $79.99 shipped at Amazon.com right now:
