Paul Moriarty grabbed his first win as Cardiff director of coaching after his side strolled to a 30-3 victory at Ebbw Vale.
Moriarty suffered a shaky start with last season's Premiership champions following the shock opening day defeat to Swansea.
But the former Scarlets forwards coach saw his men bounce back to winning ways as Ryan Howells bagged two tries at Eugene Cross Park.
Captain Ryan Shellard led front the front for the Blue and Blacks before wing Howells crossed for a double to kick-start the campaign.
Matthew Jones also touched down in a routine victory while Gareth Davies scored 15 points with three conversions and three penalties.
Swansea and Aberavon continue to set the pace at the top of the table thanks to home wins over Newport and Glamorgan Wanderers.
They are joined in the upper part of the table by Neath, who were the only other away victors 35-19 at Llandovery. Once-capped Wales international wing Nathan Brew scored his first try for the club following his move from Bristol.
Bedwas took on Llanelli and came out on top. Two late, late Gethin Worgan penalties secured Bedwas a thoroughly deserved 30-23 victory.
The home side showed plenty of guts and determination to overturn a halftime deficit of 9-20 with man of the match Deri Mattravers edging Bedwas in front with a barn storming run to the line. With time running out Worgan ensured there was no way back for Llanelli as Bedwas bounced back from their opening day defeat to Neath to record their first scalp of the campaign.
In the other match played on Saturday, Cross Keys recorded their first win of the campaign by beating Pontypool 30-23. Pontypool remain winless but their losing bonus point means they sit twelfth on the table, just ahead of Ebbw Vale and Llandovery.
