As Earnhardt said you will be fine with that unit.
That PSU is made by Enhance, and from what I've read they are mainly a server and industrial power supply manufacturer and contract manufacturer for desktop supplies. Silverstone also designs their own units and then uses contract manufacturers to make them, so they are a good brand, unlike many of the power supplies out there which are made by people in the backstreets of China with less electrical knowledge than a 13 year old nerd here in the USA. They have to say a 1500w PSU because there are still some crap units which split power between multiple rails, so to deliver the power that card needs (about 500w) you need a rail with at least 42 amps (42A x 12V = 504W), or a combination of two rails. Also it is a good idea to, whenever it is feasible, to have a power supply rated at twice your need for optimal efficiency, to counter capacitor degeneration with age, and for future expansion.
Back about 6 or 7 years ago, the ATX specification capped power supplies on the 12v rail to 18 amps each, about when the HD 2000 series came out, and graphics cards started to become very power hungry. The reason was for protection, and why mult-rail PSUs became the standard. Nowdays there is no limit, and reputable manufacturers use digital protection boards instead of simple (unreliable) fuses. But there are still plenty of garbage power supplies out there, usually rated to twice their capacity, and easily able to be spotted because they have an insane price to rated power ratio (such as 750w for $25).
If you're ever in the market for a new PSU though, I would stick with SeaSonic and Enermax units. They are expensive, but they're the best you can get.
