document: Three converted first-half tries from Cory Hill, Ashton Hewitt and Jason Tovey gave the Welsh side a 24-0 lead at the break that did not flatter them.
  Carl Meyer crossed after the break for a fourth try to secure the bonus point.
  Paddy Butler, Mosese Ratuvou and Watisoni Votu all added tries for Pau but the Dragons were always in control.
  Victory leaves the Dragons top of Pool Two, two points above second-placed Sale Sharks after their win over Castres.
  Second row Hill's brilliant individual try gave the visitors an early lead, before a Tovey penalty made it 10-0 and then Sarel Pretorious' pass saw Hewitt burst through a gap in the Pau defence to cross for the second try.
  Tovey ran clear after a mistake by the French side to add the Dragons' third try and he duly converted, before kicking through to Meyer for the fourth try after the break.
  With Hill sent to the sin-bin, Pau capitalised to score through Butler, but they failed to convert and a Tovey drop-goal made it 34-5.
  Word Cup-winning New Zealand centre Conrad Smith came on for his Pau debut and, shortly afterwards, Ratuvou barged his way over the line for the home side's second try.
  Fijian Votu added a late third score but Pau remain bottom of the pool.
  Dragons director of rugby Lyn Jones told BBC Radio Wales:
  "We're absolutely delighted. It was a great performance from us. It was as good as we get
  "We were a far better team than them and we deserved to come away with the spoils.
  "We kept (Colin) Slade quiet and they couldn't deal with us."
