Is this 500 watt psu any good

[li4m53]

I need a new graphics card since I currently have an ati 4550, but the problem is I only have a 300 watt psu. So i found this psu which is a OCZ 500W StealthXstream. However i'm not sure if its any good.

Heres a chart http://www.ocztechnology.com/resources/drivers/500wchart.JPG

Would this be a good enough upgrade to get a decent graphics card?


Thanks for any help
