Yeah, the VS series are not officially rated on the 80 Plus scale, but it's still not a bad PSU. Honestly I'd probably go with a CX modular if you're looking for something sub $100. You get an 80 Plus Gold rated PSU that'll look good in any case because it's modular.
 
^I think OP meant clean current.

@ OP, if the PSU fails to provide clean current it will damage the components. And cheap/crap PSU's inflate the wattage then they actually provides, so eventually they will fail on load. Worst case scenario the PSU can/will take out other components with it too.
