No , your PSU is more than sufficient to run either option you want to do.

If it's a Capstone , Lightning , or Tachyon series version of a Rosewill , they are great PSU's made by Super Flower.

850 watts should be enough, but I've had enough bad experiences with Rosewill power supplies that I'll never trust another one again.

I have heard horror stories about Rosewill, and I have also heard people praise them. I guess it is like most things in life, sometimes you get the cream, and sometimes you get the clabber.

SR-71 Blackbird has it right, if it's from one of their high quality lines he listed, then you're good.

I would upgrade your PSU , that Rosewill isn't very good.
