Are you looking at buying the VS650? Or do you already own it?
If you already have it, and you are not overclocking, then you should be ok with that PSU. It's not the best on the market but it's fine for basic use. It just has come cheaper capacitors in its construction. It's not recommended for systems that will be overclocked though.
If you are looking at buying it, don't. There are better units for the same price.
