What's a PSU that's good for my rig?

[Anarch1012]

This is my PC, http://support.hp.com/ca-en/document/c04319096 but instead of a GeForce GT 635, I just got a GTX 960 Superclocked, and I was wondering what PSU would fit this PC perfectly. I want at least a 500watt PSU, and my budget will be 100$, but I'm hoping to spend less.

that PC has a 460 watt PSU which would prk as long as it has connectors and at least 20A on each 12V rail or 35A if it is single rail. But this PSU that i liked is 40$ after rebate and manufactured by seasonic which means it is a good unit.
