Is it bad to use a 550W power supply on this?

A 550W PSU will easily allow you to put almost any GPU in this build. You could use a 770 or 280x easily. Point is, 550W is a lot of power for a i3 which is a low power CPU.

You'd only need more than a 550 W PSU with a Crossfire or SLI setup. Even the most powerful single video cards on the planet still only draw around 300-350 W under full load.

That said, I know nothing about Corsair's VS series and how reliable they are. They may be fine, but I'd be more comfortable recommending one from their CS or TX lineups. But yeah, 550 W from a reliable unit is ample.

What about my second question? Will the power supply work with the case? In Cooler Master website, it says that the Power Supply Type is Standard ATX PS2 while in the power supply, it says Compatibility: Conforms to ATX12V v2.31 standard, and is backward compatible with the ATX12V 2.2 and ATX12V 2.01 standards

I have no idea what this means.

This was the cheapest one I could get.

"ATX" is the name of the form factor. Motherboards, cases and power supplies conforming to the ATX standard should (should!) always physically fit together. Just watch out for other form factors, such as microATX or ITX, though there's some cross-compatibility.

For future reference I'd caution strongly against the attitude that you ought to get the cheapest PSU you can find. Don't make the assumption that an unknown PSU is safe or reliable; there's a lot of Brand X garbage in the PSU market that may not even have proper industry-standard safety features. The PSU is not the place to go super-cheap in your build.

You're fine in this case. A $60 PSU from Corsair is not at all likely to die or fry your system. I don't believe they would make a truly "bad" PSU. I just haven't had experience with their VS series, so I can't speak for their performance.
