Quality unit great price.

Out of the many P.S.Us I had to pick from on a budget I decided to choose this P.S.U. it stood out for it's specs and price. I was not let down. It had more than enough power for my new P.C Build. Impressively running a hungry 200watt graphics card, motherboard, Fans, ARGB lighting without ANY power drop issues. Extremely quiet, stays cool. Highly recommended.
