PSU good enough for this GPU?

Hardware Hub GPU
1

Upgrading my uncle's PC. He has a Dell Studio XPS 7100 with a Radeaon HD 5450 currently installed. Now from the information I got here http://tinyurl.com/2e9qpq5 this PSU should be good enough. The GPU in question is my old BFG Geforce 8800 GTS 640mb. It may be the OC edition I can't remember (I do not have it with me right now). So what do you guys/gals think?

*Ctrl+F: watt*

*Sees 460*

I looked through some sites and saw that 400 was the bare minumum and that you should have at least 600. Then again, I am probably unreliable.

So this is the equation: 430W(PSU Wattage) - 19W(5450 average wattage draw) + 143W(8800 average wattage draw) = 554W

So go with something around 600+ W for future upgradability and overclocking

in my oppinion, it would be fine.... its cutting it close... but i think it would be good.

put the card in, play some games... if the pc randomly turns off... get a better PSU. no point in buying a psu if you dont need one, so test it first.

Aren't Dell PCs designed in such a way that you can't use standard aftermarket power supplies?

Are you talking about the proprietary connectors?
