It's no problem. What are these places for after all
And personally i wouldn't trust that PSU but I am running i7 system. On the system you intend to put it in then it's entirely up to you if you wanna risk it. Yes it should run it all fine but like i said it's your call.
The only concern and something you need to look out for is the 12V rail Amperage. I notice on that one it states "+12V@17A". Do a PSU calculation online if you need to for all the components you are going to have in total on that system (ie. http://www.extreme.outervision.com/p...ulatorlite.jsp
) Should give you a rough estimate for the Wattage. In regards to Amps then i'd say you should be ok with that Graphics card plus other components so long as you don't go over the top with HDD's and such.
In the past i run a E6400 @2.8GHz, 4GB ram, 2x HDD's, Creative Sound card, 2x Optical drives and a Nvidia 8800GTS off a 500W 22Amp PSU. And that was just some generic PSU too. Run fine for a couple of years but i think it's down to luck also. If you want to take the risk that is. I wouldn't take that risk these day's with my i7 setup and run it all off a Corsair TX850W PSU. So i think you'll get my point
Hope you get everything sorted anyway and please come back and let us know if you finally do. Always nice to know when something comes together
